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.

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.

Conclusion

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.

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.

Conclusion

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.

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.

Conclusion

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.

How to Choose the Right PoE Cabling

Power over Ethernet (PoE) is a technology that enables electrical current to be transmitted over standard Ethernet network cables rather than traditional power cords. By operating power and data transmission over a single Ethernet cable, PoE has achieved popularization in a variety of applications, such as IP cameras, IP phones and Wireless Access Points. However, if there is no right PoE cabling, PoE can encounter cable heating and connectivity issues which will adversely affect the transmission performance from PoE switch to these devices and in reverse. So in this article, we will discuss some considerable factors and FS product recommendations related with PoE cabling.

Importance of the Right PoE Cabling

Heat generation in cable bundles is one of the biggest issues that affect PoE performance. When power is added to balanced twisted-pair cabling, the copper conductors generate heat and then temperature rises. In the meanwhile, high temperature will bring about higher insertion loss and shorten permissible cable lengths in result. Due to more power dissipation in cabling, bit error rate and power costs increase consecutively. A proper and right PoE cabling with PoE switch becomes especially crucial to the network quality and reliability.

Cabling Considerations for PoE Switch

According to the above introduction, we have known the importance of right PoE cabling. Now, some cabling considerations with PoE switch are suggested to help lower cabling temperature.

  • Category Cabling

Higher category-rated cable typically means larger gauge size. When power currents increase, these larger conductors can perform better than smaller cable. For instance, with larger gauge size, Cat6a can reduce resistance and keep power waste to a minimum degree as it has a lower temperature increase compared to smaller gauge Cat5e. This advantageous performance will create additional flexibility with larger bundle sizes, closed installation conditions and higher ambient temperatures.

  • Cable Structure

Copper cable can be divided into UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) cable based on cable structure. Cables with metallic or foil shields, like STP cables are proved to dissipate more heats than UTP (Unshielded Twisted Paired) cables. If possible, choosing a Cat6a STP cable with a foil shield around each pair which can dissipate more heats than Cat5e UTP cable.

  • Installation Configuration

Cables plugged into PoE switch in the middle of the bundle always heat up more than those toward the outer layer of the bundle since they have difficulty in radiating heat out into the environment. Therefore, separating large cable bundles into smaller ones or avoiding tight bundles will help reduce temperature rise. On the other hand, enclosed conduit can contribute to heat issue. To use ventilated cable trays would get better airflow.

FS PoE Switches & Ethernet Cables Solution

When it comes to PoE cabling, we will need PoE gigabit switch and Ethernet cables to construct a network. For PoE switch, FS offers fully managed PoE switches with SFP/SFP+ ports, which deliver robust performance for increasing networks. The details of FS PoE switches are listed as below.

As for small-sized families or networks, an 8 port PoE switch is adequate, such as S1130-8T2F (130W) or S1250-8T2F (250W). While for larger enterprises or businesses, a 24 or 48 port PoE switch would be better, like S1400-24T4F, S1600-24T4F or S1600-48T4S. For Ethernet cables, FS also provides various types of cables including Cat6a, Cat6, Cat5e and Cat7 Ethernet patch cables to satisfy your cabling solution demands.

Conclusion

Choosing the right and proper PoE cabling is essential. The cabling you choose decides how fast your network can be. And whether PoE devices can operate well depend on three parameters, including category cabling, cable structure and installation configuration. For cabling equipment, FS provides varieties of PoE switches and high quality Cat5e, Cat6, Cat6a and Cat7 PoE cables with shielded or unshielded type. If you need to build PoE connections, FS is a good choice.

Understanding Combo SFP Port on Ethernet Switch

For new comers who are not familiar with the structure and functionality of Ethernet switch, they are apt to get confused with different ports built in for different connection. Except for those common ports on SFP switch, such as SFP port , there is another port called “combo SFP port”. Do you know what is it and what is the difference between SFP port and combo SFP port? In this article we aim to give you comprehensive understanding of combo SFP port on Ethernet switch.

What Is Combo SFP Port on Ethernet Switch?

In a nutshell, a combo SFP port is regarded as a single interface with dual front ends, i.e. an RJ-45 connector and an SFP (Small Form Pluggable) module (also called Mini-GBIC) connector. In other words, this is a compound port which can share the same switch fabric, port number and allow the users to configure their SFP switch according to different applications. But the two different physical ports can not be used simultaneously. It means that you can either plug a cable into copper 10/100/1000 interface, or plug the cable into SFP slot.

A combo SFP port is a way to provide different types of connectivity and give users the power and flexibility to configure SFP switch for unique application requirements. Below is the demonstration of 4 combo SFP ports on FS SFP switch.

What Is the Difference Between SFP Port and Combo Port?

Combo interface, also known as optoelectronic multiplexing interface which is a switch device panel with two Ethernet ports: an optical port and an electrical port. Combo electrical port and its corresponding optical port are logically multiplexed, and the user can choose which one to use according to the actual network demand. But when one of the ports is activated, the other port is automatically blocked since they can not be used at the same time.

While SFP port (mini-GBIC port), a small form-factor hot pluggable interface, is designed for high speed and density SFP connection. SFP ports on SFP switch support both copper and optical links. When SFP ports on SFP switch are inserted into SFP modules with electrical ports, Ethernet copper cables are needed for data transmission. If SFP ports are plugged by SFP optical modules with optical ports, then fiber patch cables are required.

Introduction to FS.COM 24 Port Switch With 4 Combo SFP Ports

There are many SFP switches with combo SFP ports, but today we are going to take FS S3800-24F4S: 24 port switch with 4 combo SFP ports as an example to illustrate the usage of combo SFP ports on a SFP switch.

S3800-24F4S 24-port Gigabit switch comes with 20x 100/1000Base SFP, 4x 1GE combo and 4x 10GE SFP+ slots which offers up to 128Gbps switching capacity to synchronously process the traffic on all ports without any packet loss. The 4 combo SFP ports on switch facilitate the application of different connectivity, making it more flexible to configure the switch. In addition, this diversiform port combination form provides a high bandwidth aggregation connectivity for multiple switches to enhance network capacity. All in all, this 24-port Gigabit managed switch is fit for enterprise network operators who pursue high performance and low power processor to provide full speed forwarding and line-dormant capacity.

Conclusion

From the above introduction, we have known that combo SFP port on SFP switch is a port type to carry out different connection applications. For combo SFP ports on Ethernet switch, only one of the twisted pair port or SFP slot can be used. For SFP ports on SFP switch, it can be either plugged into Ethernet copper cable with RJ45 SFP module, or optical fiber cable with fiber SFP module to achieve short and long reach distance transmission. What is more, FS S3800-24F4S is a good example of combo SFP ports on switch. If you have any need, FS would be a choice.
