Ethernet Patch Panel: Keystone vs. Feed-Through vs. Punchdown


General Introduction on Patch Panel Ethernet

Patch panel is a device designed with a few jacks to monitor, interconnect and test circuits on network connecting and circuits routing. It is very convenient and is commonly used in computer networking, radio, audio, TV, etc.

Nowadays, patch panel ethernet, namely, ethernet patch panel, is almost the most common application of its kind. It is of great importance for cable management in data centers. Serving as the nerve center of the cabling network, the importance of patch panels cannot be neglected. There are different forms of ethernet patch panels. Here, let’s focus on the mostly used three, keystone patch panel, feed-through patch panel and punchdown patch panel.

Patch Panel Ethernet Comparison – Keystone vs. Feed-Through vs. Punchdown

Keystone Patch Panel Ethernet

Keystone patch panel is a traditional form of patch panel Ethernet. It is always in flat style with 1U rack space (24 ports). The clear numbering on the front provides a quick, easy way to identify cable runs, grounding wire included. In addition, keystone lets you create your own color coding scheme. You can choose to card into different color modules for color code management.


Feed-Through Patch Panel Ethernet

Feed-through patch panel is an in-line series of connections mounted onto a frame, which enables network cables to be terminated in an orderly manner. It is usually in 1U (24 ports) and 2U (48 ports) configuration. The feed-through patch panels have RJ45 ports on both sides for easy installation.

It can be repaired without punching a large amount of wires onto the back of the panel, which keeps the patch cable clean at the back of the panel. Without punching down the wires to the ports, it saves time and energy while maximize productivity. Among all the feed-through patch panels, Cat5e and Cat6 patch panel are commonly used in data centers nowadays.


Punchdown Patch Panel Ethernet

Punch down types are available in Cat5e or Cat6 patch panel. In the front of the panel, RJ45 ports (usually 24 ports) are used to directly connect Ethernet copper cable. And these ports have their own numbers as well for easy identification. In the rear, it has patch panel module with color markings for punching down Ethernet cable. This type of panel is a litter cheaper than other panels.

Normally, color coded labels are designed for T568A and T568B wiring configurations. You should insert each wire into its own slot and then terminate the wires with right configuration match. Once you finished the cable installation, you should have a double check with a cable tester to see if all the wires are correctly terminated.


Summary on Patch Panel Ethernet Comparison

Among the different forms of patch panels, keystone can provide different color module management. Punchdown is cheaper but with complex cable installation steps. While, feed-through patch panel is more expensive but it is less messy and is quite suitable for high-density network system, which can protect cable and improve cable management efficiency.

What Is Twinax Cable?

What Is Twinax Cable?

Speaking of Twinax cable, you might think of coax cable. They are two similar cable types. The difference is that the former one has two inner conductors in stead of one inside coax cable. The twin conductors of the Twinax do not carry individual signals, they work in a half-duplex mode, that is, both connectors are required to transmit data.

Twinax cable is often used for 10 Gigabit Ethernet Network. It has been used commonly to connect network hardware through SFP+ interfaces in short-range signaling applications such as in local area networks for its relatively low cost. To be exact, Twinax SFP+ is a copper 10 Gigabit Ethernet cable which comes in Twinax cable assembly and connects directly into an SFP+ housing.


Twinax Active vs. Passive

You must know that Twinax cable has two different types, active Twinax and passive Twinax, whose classification normally depends on Twinax cable length.

Generally, Twinax cables shorter than 7 meters are passive and those longer than 7 meters are active, but this may vary from vendor to vendor.

An active Twinax has active electronic components carrying a 10 Gig Ethernet signal over long lengths in the SFP+ housing to improve the signal quality; a passive Twinax is mainly just a straight “wire” and contains few components. Therefore, active Twinax cables are a litter more expensive than passive Twinax cables.


Twinax Cable vs. Fiber

Normally, when choosing cables for network connecting, Twinax and fiber cable are two major considerations. However, which one is a better choice? Read on and find out the answer.

Twinax cable is a lower cost alternative to traditional fiber and twisted pair copper cabling in data center applications when you include switch, NIC and cable. Typically, we see Twinax being used between the server and the Top of Rack (ToR) switch. The advantage in this configuration is that the Twinax connection is much cheaper than a fiber optical cable. The disadvantage is that you are limited in distance and you may have some cable interoperability issues to deal with, which fiber cables won’t.

Nevertheless, if you want to create an ideal short distance connection scheme using Cisco 10GbE SFP+, Twinax cable Cisco is a better choice.



From all the above, you will see that Twinax cable is divided into two types, namely, passive and active cable according to Twinax cable length. It is an ideal 10GbE solution used to integrate storage and data networks for servers connected to Top of Rack switches. It has low power consumption and higher reliability. Passive Twinax is recommended when the transmission distance is no more than 7m and active cable is suitable when the distance is over 7m.

Can I Use Cat6 Cable on Cat5 Network?

Nowadays, internet data cabling has become an important part of our daily life. While, with fast update of technology, the old ethernet cable versions are being substituted by the new ones for better experience. For example, Cat6 cable is an advanced version over an older one Cat5. If I update to Cat6 cable on previous Cat5 network, will it work? Read through this post and find out the answer.


What Is Cat5 Cable?

Cat5 cable is a twisted pair cable for computer networks. Consisting of four twisted pairs of unshielded copper wire, Cat5 is a multimedia cable for carrying signals to transmit information, voice and other information communication services. It is widely used in broadband access projects such as broadband user premises networks. The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair. Cat5 is also used to carry other signals such as telephony and video. The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95.

What Is Cat6 Cable?

Cat6 cable is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5 cable standards. Similar to Cat5, Cat6 cable is made up of four twisted pairs of copper wire. Compared with the previous cable versions such as Cat5 and Cat5e cable, Cat6 cable has a better performance of up to 250 MHz and a faster speed of 10Gbps.

Cat6 cable must be properly installed and terminated to meet specifications. The cable must not be kinked or bent too tightly (the bend radius should be at least four times the outer diameter of the cable). The wire pairs must not be untwisted and the outer jacket must not be stripped back more than 12.7 mm.

Can I Use Cat6 Cable on Cat5 Network?

Of course, Cat6 Cable can work on Cat5 network. It is backward compatible with previous specifications, which means it can be effectively used with Cat5 network.

From the introduction above, the major components between Cat6 cable and Cat5 cable are similar. What makes them different are their electrical specifications, or signal transmission capabilities. Category 6 cable has better specifications than 5 or 5e, enabling it to support faster data transmission when installed with compatible devices.

In fact, it’s typical to use newer cabling types when upgrading a physical network infrastructure, even though the hardware is still using older standards. This is how a network admin can get newer cable installed in preparation for a future time when newer hardware will be deployed.

Things You Need to Know:

The major differences between these cables are their capabilities when put into use. Nevertheless, it is apparent that both Cat5 and Cat6 cables use the same end piece known as RJ-45, which is capable of connecting to Ethernet jack on a computer, router, etc. They can be plugged in to the same ports. Therefore, Cat6 cable works on Cat5 Network. However, Cat5 cable can’t be used on Cat6 network since Cat6 network has more requirements on cabling performances and capabilities, which Cat5 cable can not reach.

What Is VXLAN and VXLAN Switch?

The past few years have witnessed a massive change in the world of information technology by reason of network virtualization and cloud computing. Virtualization brings the efficiency of physical resource and energy use as well as the challenge for network administrators to support large-scale and dynamic workloads with multitenancy. In order to seek a way for addressing the challenge of network scale and workload mobility, VXLAN is released as one of several network overlay technologies. In this article let us probe into the understanding of VXLAN technology and VXLAN switch.

VXLAN for cloud data center

Figure1: VXLAN for cloud data center

Understanding of VXLAN

VXLAN, also called Virtual Extensible Local Area Network, is a network virtualization scheme that enables users to create a logical network for virtual machines (VMs) across different networks. It is designed to provide layer 2 overlay network on top of a layer 3 network by using MAC address-in-user datagram protocol (MAC-in-UDP) encapsulation. In this way, you could possibly create 16 million networks by using VXLAN instead of 4096 VLANs. To be brief, VXLAN can provide the same service as VLAN does with greater extensibility and flexibility.

How Does VXLAN Work?

VXLAN adopts Layer 3 multicast to support the transmission of multicast and broadcast traffic in virtual network. In this environment, a VXLAN gateway device can be used to terminate the VXLAN tunnel and forward traffic to and from a physical network. The following picture helps to deeply understand VXLAN technology.

how does VXLAN work

Figure2: How VXLAN Works

VXLAN gateway: A VXLAN gateway is mostly a bridging between VXLAN and non-VXLAN environments by serving as a virtual network endpoint. For instance, it links a traditional VLAN and VXLAN network.

VXLAN segment: A VXLAN segment is a Layer 2 overlay network over which VMs can communicate. One thing to be aware of is that only VMs within the same VXLAN segment can communicate with each other.

VNI: Virtual Network Identifier (VNI) is also called VXLAN segment ID. The system uses the VNI along with the VLAN ID to identify the appropriate tunnel.

VTEP: The VXLAN Tunnel Endpoint (VTEP) terminates a VXLAN tunnel. And the same local IP address can be used for multiple tunnels.

VXLAN header: VXLAN header carries a 24-bit VNI to uniquely identify Layer 2 segments within the overlay.

Overview of VXLAN Switch

In data center, VXLAN is widely applied in creating overlay networks that sit on top of the physical network, enabling the use of a virtual network of switches, routers, firewalls and so forth. When it comes to VXLAN switch, it usually possesses the features of scalability and agility. What is more, VXLAN network switch can offer multiple solutions for private, public and hybrid cloud networks. Take FS S5850-48S2Q4C 10GbE switch as an example, it comes with 48 10G SFP+ ports and 6 hybrid 40G/100G uplink ports. It is a VXLAN fiber switch with advanced features, including MLAG, VXLAN, IPv4/IPv6, SFLOW, SNMP and etc., which is an ideal choice for traditional or fully virtualized data center.

FS S5850-48S2Q4C VXLAN switch

Figure3: FS S5850-48S2Q4C VXLAN switch


With the rapid development of VLAN technology and layer 2/3 networks, more higher network management technologies will arise definitely. VXLAN technology is one of them to solve the problem of limited scalability at present and bring more convenience for today and future networks. VXLAN support Gigabit Ethernet switch has been accepted as a better solution with sufficient links and capacity to handle massive traffic in cloud environment. If you are looking for professional and cost-efficient network switch solutions or VXLAN switches for networks and data centers, FS is a good choice.

How to Choose an Appropriate Rack Mount Fiber Enclosure?

With the ability to create easy-to-manage cabling environment and effectively boost network performance, fiber enclosure is playing an increasingly important role in current equipment rooms, central offices and high-density data centers. When it comes to rack mount cabling applications, rack mount fiber enclosure is particularly popular. In order to meet the needs of various users, there are a number of rack mount fiber optic enclosures available in the market. In this article we are going to introduce several fiber enclosures with different configurations and types and provide some considerations for you to choose an appropriate one.

Rack Mount Fiber Enclosure Configurations

Rack mount fiber enclosures are usually made for 19 inch rack mounting with rack units (RU) of 1U, 2U, 3U and 4U which are loaded with fiber optic patch panel, cassettes or modules. For 1U and 2U rack mount enclosures, they offer full front and rear access with a drawer that slides forward and backward. 3U and 4U rack mount enclosures feature a fixed bulkhead design. Among them, 1RU rack mount fiber optic enclosures are the most commonly used size in data center server rack cable management.

different rack units of fiber enclosure

Figure1: different rack units of fiber enclosure

Rack Mount Fiber Enclosure Types

In general, there are three types of rack mount fiber optic enclosures: cover removable type fiber enclosure, slide-out type fiber enclosure and swing-out type fiber enclosure. The cover removable type is an early type of fiber enclosures which is more economic but harder to access. By contrast, slide-out type and swing-out type are more expensive than the cover removable type. While you can still benefit a lot from cable installation and maintenance. Since slide-out type and swing-out type respectively feature a convenient slide-out support tray and an integrated swing-out tray, you do not need to remove the whole fiber enclosure from the rack to gain internal access. It is proved to be time and energy saving in the long run.

Considerations for Choosing an Appropriate Rack Mount Fiber Enclosure

In this part we will concentrate on the reference guides when selecting a rack mount fiber enclosure which is a troubling question in some data center operators.

  • Physical Requirement

Before buying a rack mount fiber optic enclosure, you should know precisely the external specification that you want. You can measure the height, depth, width and weight of your equipment which will help you determine what type of fiber enclosure you need. An important thing to note in this process is that you’d better choose a bigger one for your existing equipment and near-future growth.

  • Accessibility Requirement

A proper rack mount fiber enclosure should provide plenty of access points through the rear and top of the cabinet for installation and ongoing maintenance. Not only the fiber optic cables but also the hubs, routers, fiber patch panels and monitors are needed to be mounted in the enclosure. Remember that any accessories that are not rack-mountable will result in additional trays, shelves and mounting accessories.

  • Budget

Sometimes it is easy for people to get into the dilemma that whether to choose a budget-friendly equipment for the time being or the expensive one with high-quality for future. At this time, you need to combine your budget and other factors that matter to you and then make your investment decision.


As an expert of optimizing data center space, the rack mount fiber optic enclosure makes the fiber cabling system the most serviceable and manageable. It comes with different rack units of 1U, 2U, 3U, 4U and various mount types. You can choose the appropriate one according to the physical requirement, accessibility requirement and budget of rack mount fiber enclosure. If you are looking for high-quality fiber enclosures and fiber patch panels, FS would always be your nice choice.

What Is Access Switch and Why Do We Need It?

The Cisco hierarchical model, also known as hierarchical internetworking model, is a three-layer model for network design which is widely used in industry. It divides enterprise networks into three layers: core, distribution and access layer. As the lowest level of Cisco three-tier network model, the access layer is responsible for providing end user devices with a connection to network resources. Access layer devices contain hub, multi-station access unit and switch. In this article we will put emphasis on access switch. In the meanwhile, some important features of access switch will be introduced as well.

The Overview of Access Switch

Access switch is the only one that directly interacts with end user devices. Because an access network switch connects the majority of devices to the network, it normally has the highest port density of all switch types. In spite of the high port count, access switch usually provides the lowest throughput per port. For example, most modern access switches come with a 10/100/1000Mbps copper Ethernet connection to end devices. While core and distribution switches commonly use between 10Gbps and 100Gbps fiber optic ports. An example of this is FS S2800-24T4F 24 port 100/1000BASE-T copper Ethernet switch. It is designed to meet the demand of cost-effective Gigabit access for enterprise networks and operators.

The Difference Between Access Switch and Other Switches

Access switch, distribution switch and core switch perform different functions. Distribution switches collect the data from all the access switches and then forward it to the core layer switches. A core switch is a high capacity switch that is generally positioned within the backbone or physical core of a network. In small networks where there are only a few of servers and clients, access Ethernet switches are adequate without needing core switches or distribution switches. What is more, there is generally only one or two core switches used in a small or middle-sized network, but the distribution layer and the access layer might have multiple switches. The figure below shows where the access switches locate in a network.

access switch in the access layer

The Important Features of Access Switch

Access layer switch facilitates the connection of end node devices to the network, such as PC, modems, IP phone, printers and etc. On this account, they offer many features that the upper tiers do not require. For example, an access switch can create separate collision domains for each connected node to improve performance. What is more, some access switches support Power over Ethernet. An access Gigabit PoE switch can supply power to many endpoint devices, including wireless access points and security cameras. Additionally, access layer switch is more adept at interacting with endpoints from a security perspective. Port security, 802.1X authentication and other security mechanisms are built directly onto access switch software.


In the construction of a network, there might be access switch, distribution switch and core switch. Although access switch is not usually used in large network, smaller network is where access switch comes in. As the demand for higher Ethernet speeds and more enhanced link utilization increases, data center networking is requiring 10GbE switch at the access layer to optimize performance. If you have demand for access switches, FS could provide and satisfy your needs.

Difference of Connecting 2 Switches via RJ45 Port or SFP Port

In computer networking realm, Gigabit Ethernet is a version of Ethernet technology broadly used in local area network (LAN) for transmitting Ethernet frames at 1Gbps. Gigabit Ethernet normally employs optical fiber connection to transmit information at a relatively high speed over long distance. For short distance, copper cables and twisted pair connection are used. When it comes to Gigabit Ethernet switch, there are typically two ports as well: RJ45 copper port and SFP fiber port. But do you know the difference when you connect two network switches together via RJ45 port or SFP port? In this article we will introduce Gigabit port vs SFP port of Ethernet Gigabit switch and guide you to choose a proper RJ45 connection or SFP connection.

RJ45 port and SFP port of Ethernet Gigabit switch

RJ45 Port and SFP Port of Gigabit Ethernet Switch

  • RJ45 Port

The RJ45 port of Gigabit Ethernet switch is a built-in port. For purpose of connecting two network switches, you can connect them with two RJ45 ports by merely using one Cat5 or Cat6 network cable. The following table shows the specific rate and bandwidth of this connection:

Shielded level Maximum transfer rate(distance of 100m) Maximum bandwidth
Cat5 network cable Unshielded 1000 Mbps / 1 Gbps 100 MHz
Cat6 network cable Shielded or unshielded 1000 Mbps / 1 Gbps 100 MHz
  • SFP Port

The SFP port of Gigabit Ethernet switch is in line with 1000BASE-T (IEEE 802.3ab) standard. The transmission rate of it can reach 1000Mbps. Built-in SFP ports on switch enable optical or copper links by inserting the corresponding SFP module: fiber SFP or copper SFP. When SFP port is inserted in 1G copper SFP module, the Ethernet copper cables (Cat5e, Cat6 and Cat7) must be used for data transmission. While when SFP port is pl ugged into Gigabit fiber SFP module, fiber optic patch cables (LC fiber) are needed to support connections.

RJ45 Connection and SFP Connection of Gigabit Ethernet Switch

In order to intuitively explain these two connections of RJ45 port and SFP port, we will take UniFi switch as an example to demonstrate the RJ45 copper connection and SFP fiber connection between two switches. The left side is the SFP connection of UniFi switch and the right side is the RJ45 connection. As the article already mentioned above, SFP connection requires the usage of two SFP electrical modules and a Cat5e/Cat6/Cat7 cable or the usage of two SFP optical modules with optical port and a fiber jumper. While RJ45 connection only requires a Cat5e/Cat6/Cat7 cable.

SFP connection and RJ45 connection

RJ45 Connection and SFP Connection: How to Choose?

The performance of RJ45 connection and SFP connection is basically the same, but the SFP port wiring cost is higher. Nevertheless, SFP port is still indispensable since it can support both SFP optical modules with electrical ports and optical ports. What is more, the transmission distance is obviously longer than RJ45 port when using SFP port optical transceiver. In the meanwhile, SFP connection between two switches performs better in practical applications with high flexibility and scalability.


SFP port empowers two Gigabit switches to connect to a wide variety of fiber and Ethernet cables so as to extend the switching functionality throughout the network. However, RJ45 connection still has the advantage of cost effective characteristic. Nowadays, 10GbE switch is becoming a trend. If you are looking for 10Gb network switch: 10Gb fiber switch with SFP ports or 10Gb copper switch with RJ45 port, FS can all fulfill your specific needs.

This 48 port managed switch with fixed 10G SFP+ ports for uplinks can satisfy the demand for now and future.

48 Port 10GbE SFP or Copper Switch: Which Is the Data Center Performance Choice?

10GbE network can be achieved both by 48 port SFP switch and 48 port copper switch. So, which one is the data center performance choice?

  • Price

10GBASE-T copper switch with 48 port uses copper cables to transmit 10Gbps data. This may help to save much money since copper cable infrastructure is far less expensive than the fiber optics of 10G SFP+ switch. So 10GBASE-T 48 port copper switch is much cheaper and provides the most economical solution than SFP+ solution.

  • Latency and Power Consumption

The power consumption of 48 port 10GBASE-T switch is 1.5 to 4 Watts per port depending on the distance, while 48 port SFP switch uses less power consumption which is typically less than 1 Watts per port. In addition, 10GbE SFP switch offers better latency with about 0.3 microseconds per link. 10GbE RJ45 switch latency is about 2.6 microseconds per link due to more complex encoding schemes within the equipment. With compelling improvement in lower latency and power consumption, 10GbE SFP switch has become the interconnect of choice for latency sensitive application with enhanced reliability and network performance.

  • High-Speed Application

Since 48 port SFP switch is endowed with the advantages of lower power consumption and latency, it is more suitable for large high-speed super-computing applications where latency is a critical factor and high port counts can create significant power savings.

  • Backwards Compatibility

48 port 10Gb copper switch comes with the advantages of being an interoperable and standards-based technology that uses the familiar RJ45 connector. It provides backwards compatibility with legacy networks. While SFP switch is limited with little or no backwards compatibility.


48 port 10GbE Switch is well poised for an expanding role in data center applications and the future of which is responsive in satisfying the market needs. Although 10G 48 port switch with fiber has lower latency and power consumption, 10G 48 port switch with copper is still popular for its cost-effectiveness and backwards compatibility. Each has its own advantages and disadvantages, you can make a choice according to you needs.

24 Port Switch SFP Port vs RJ45 Port: How to Choose?

Gigabit switch that offers greater speed and compatibility continues to gain in popularity in the realm of networking world. In the present market, Gigabit switch generally has two kinds of ports: SFP port vs RJ45 port. Different ports are endowed with relevant sizes and specifications which prevent the incorrect type of connector from being plugged into them. So what are the differences between SFP port and RJ45 port of the Gigabit switch? And how to choose the proper one from them? In this article we will take 24 port switch as an example to explore the distinctions and provide some considerations when choosing SFP port vs RJ45 port.

Comparisons Between 24 Port Switch SFP Port vs RJ45 Port

  • 24 Port Switch with SFP Port

Built-in SFP ports on 24 port switch enable optical or copper links by inserting the corresponding SFP module: fiber SFP or copper SFP. When SFP port is inserted in 1G copper SFP module, the Ethernet copper cables (Cat5e, Cat6 and Cat7) must be used for data transmission. While when SFP port is plugged into Gigabit fiber SFP module, fiber optic patch cables (LC fiber) are needed to support connections.

Take FS S3800-24F4S SFP port switch as an example:

FS S3800-24F4S 24 port switch

This 24 port managed switch comes with 1 console port, 4 1GE combo ports, 20 100/1000BASE SFP ports and 4 10GE SFP+ ports. What needs for special attention is that FS S3800-24F4S 24 port switch includes 4 combo SFP/RJ45 ports which allow users to use either SFP port or RJ45 port at a time for short-distance connections.

  • 24 Port Switch with RJ45 Port

Built-in RJ45 ports on 24 port switch follow the 1000BASE-T Ethernet standard. It only supports RJ45 cables (Cat5e, Cat6 and Cat7) for 1Gbit/s transmission with the distance of up to 100m (330ft).

Take FS S3800-24T4S RJ45 port switch as an example:

FS S3800-24T4S 24 port switch

This 1000BASE-T 24 port managed switch is equipped with 1 console port, 24 10/100/1000BASE-T RJ45 ports and 4 10GbE SFP+ ports that can be used in data centers for server switching, LANs and etc.

All in all, compared with FS S3800-24T4S 24 port Gigabit switch using merely RJ45 port, FS S3800-24F4S SFP port 24 port Gigabit switch supports more types of communication cables and longer reaches of links. For short-distance links on a 24 port switch, there is not much difference for using SFP port or RJ45 port. In addition, SFP port can exchange with the port of 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX or 1000BASE- BX10-D/U. The following table lists the RJ45 connection and SFP connection of 24 port switches:

Parameter SFP Port RJ45 Port
Connection Types
  • RJ45 SFP module + network cable (Cat5e, Cat6 or higher)
  • fiber SFP module + fiber optic cable (SMF fiber / MMF fiber)
  • network cable (Cat5e, Cat6 or higher)
Max Distance MMF (550m) / SMF (150km) / Cat5 (100m) 100m (330ft)
Data Rate 1000Mbps (1G) 1000Mbps (1G)

Common Considerations When Choosing 24 Port Switch SFP Port vs RJ45 Port

For 24 port switch SFP port vs RJ45 port, how to choose the proper one for efficient network construction?

Distance: when the distance of the run is over 328ft/100m, fiber SFP port of 24 port switch must be selected instead of copper RJ45 port since 1000Mbps could only go as far as 100m over copper cabling.

Reliability: on account of electromagnetic interference, fiber is considered as more reliable than copper RJ45 Ethernet cable that uses electric signal. Therefore, if the cable run will go through some places where the electric signal can be interfered, choosing 24 port switch with fiber SFP port rather than copper RJ45 port would be more secure.

Cost: due to the lower price of Cat5e/6 cable, choosing RJ45 ports to connect 24 port switches might be more economical since RJ45 port and SFP port actually run at the same speed.

Future consideration: if you will move to higher bandwidth in the future, fiber optic cable is more future-proof one compared with Cat5e/Cat6 RJ45 Ethernet cable. So in this case, choosing 24 port switch with fiber SFP port would be more preferable.


From the aspect of performance, 24 port switch with RJ45 port and SFP port are basically the same. From an economic point of view, SFP port’s cabling costs higher. While it is still a necessary choice since it supports both fiber and copper SFP optical modules. What is more, it is in possession of superior advantages to achieve longer distance, reliability and future-proof. For SFP port or RJ45 port of 24 port switch or 48 port switch, FS is a great choice.
