How to Choose a Network Interface Card?

Network interface cards, which are also called NIC cards or fiber LAN cards. Nowadays, there are a variety of network interface cards in the market. Various network interface cards differ in transmission rate, prices and other aspects. And using different network interface cards may get different network performance. So how to choose different network interface cards is important. This post will give you some tips on choosing network interface card, which is likely to help you to choose the most suitable one.

Types of Network Interface Card

According to the bus interface type of the network card, it can be generally divided into ISA interface network cards, PCI interface network cards, PCI-X bus interface network cards and PCIe network cards. Based on different interface, it can be grouped into Ethernet RJ-45 interface network cards, BNC interface network cards, AUI interface network card, FDDI interface network cards and ATM interface network cards. In terms of transmission speed, there are gigabit network cards, 10G fiber network cards, 25G fiber network cards and 40G fiber network cards. As you can see, there are many types of network interface card. So how can we choose different types of network interface card, some tips will be given in the following part.

Tips on Choosing Suitable Network Interface Card

In the following part, some useful suggestions about selecting different types of network interface cards will be elaborated in detail.

Checking Supported Connector Types

Due to different network transmission media, common network interface cards have three different connector types. some network interface cards provide two ports on one card at the same time, and some network interface cards also provide three ports on the card at the same time. These ports are AUI port, BNC port and RJ-45 port. The AUI connector is often used with the thick coaxial cable, the BNC connector IS often used with thin coaxial cable and the RJ-45 port connector is often used with the unshielded twisted pair. Many small local area networks use a thin coaxial cable and a bus network with a BNC connector. The cost of this connector is low, but it is not easy to manage, especially for a large local area network. So you need to choose different types of network interfaces card according to different supported connectors.

network interface card

Determining the Transmission Rate

Take Ethernet network cards for example, there are 10Mbps, 10/100Mbps, 1000Mbps, even 10Gbps network interface cards in the market. In general, people is more likely to think that the network interface cards which have higher transmission rate will be the better network card. but it is not true. For example, if you insert a 1000Mbps card network card into your computer which connected with the 100Mbps twisted pair, the maximum transmission rate can only reach 100Mbps, so it is a waste to use this type of network interface card. In order to avoid unnecessary waste, you need to be careful when selecting network interfaces with different transmission rate.

Considering Prices and Brands

The prices of network interface cards in different brands is various. But there are some well-known brands, such as Intel, Netgear, Mellanox, FSand so on. Those brands are popular in customers because their products have good quality and perfect network performance, which is more likely to meet your requirements for network interface cards. Since the prices of different interface cards are effected by many factors, such as transmission rate, different ports and so on. When you comparing different network interface cards, you should not only consider the prices, but also you need to take each parameter of network cards in different companies into consideration, then make a wise choice.

Paying Attention to the Bus Type

PCI, PCI-X or PCI-E bus intelligent card are commonly used by servers and workstations. And the ISA connector is no longer support the PC. So when you purchase network card for you PC, what you should choose is the PCI-X and PCI-E or PCI card instead of the outdated ISA network card. And the PCIe network interface cards are now widely used in the customers. Here gives several types of PCI-E network cards in FS. Just show as the below picture.

10G base-T, network interface card

Figure1: Different types of 10G  PCI-E network cards in FS

Compatibility of Operating System

If you want to buy a network interface card, you need to consider which network interface can support your operating system. In general, most network interface cards can support Microsoft® Windows®, but not every interface card will support Linux or Apple’s Mac OS X. So you need to make sure that the network interface is compatible with the operating system that you are using.


As is known to all, the performance of network interface card can greatly affects the network performance and the data transfer rate of overall network. With the tips mentioned above, we hope this post can give you some inspirations in choosing the proper network interface cards. If you need any help, feel free to contact us at sales@fs.com.

How to Choose Boot Cover and RJ45 Plug for Cat5e, Cat6, Cat6a Bulk Ethernet Cables?

Bulk Ethernet cables, the network cable without connectors and boot covers, are popular among people as it is cost-effective and free of length limitation. One can customize the length of the cable and select RJ45 plugs and boot covers by themselves. This tutorial spells out how to choose suitable boot cover and plug for Cat5e, Cat6, Cat6a bulk cable.

What’s the Connector/Plug of Cat5e, Cat6, Cat6a Bulk Ethernet Cable?

For different purpose, bulk Ethernet cables are matched with keystone jacks or connectors/plugs. If applied for the patch cable, connectors are needed in the installation as they can put conductors in the right order and prevent cables from falling off. Usually made of plastic, it is mainly deployed in connecting network interface card, hub, switch, wired phones and so on. There are three types of connectors in the market, that is, RJ45, RJ11 and RJ12. This part will focus on how to choose RJ45 modular plug for Cat5e, Cat6, Cat6a bulk Ethernet cables.

FS RJ45 Modular Plug, bulk cables

Things to Consider When Buying RJ45 Connector/Plug

for Cat5e, Cat6 and Cat6a Bulk Cable

Performance Level

The first and foremost element to consider is the performance level. To effectively increase bandwidth speed, it is recommended to play Cat5e bulk cables with Cat5e plugs, Cat6 bulk cables with Cat6 RJ45 plugs, and cable Cat6a with Cat6a RJ45 plugs, say, match two components with the same performance level.

Conductor Gauges Supported

Conductor gauge refers to the size of the conductor cross section. It goes oppositely from the diameter, as the larger the figure is, the thicker the conductor looks. When punch down bulk Ethernet cables, the eight conductors should cling to the 8 contacts in the standardized order and they should be identical in gauge size. 23 AWG, 24 AWG and 26 AWG are supported by FS RJ45 connectors/plugs.

Cable Construction

According to cable construction, the network cable can be classified into stranded cable and solid cable, which is correlated with the contacts in the plugs. The first contact shown in the picture has the contact prongs that straddle the conductor, suitable for both solid and stranded cables. The second one suits only the solid cable as the jagged end pierces jacket and embeds into the strands of the conductor. The third one adopted by FS is applicable to both solid and stranded cables. Its long contact prongs spread apart to accept the conductor, ensuring the connectivity and reliability.

Three common bulk cable contacts, bulk cables

Shielded Vs. Unshielded RJ45 Connector/Plug

Shielded plugs are more expensive than unshielded ones, as shielded plugs have a metal outer shell and are often specified in areas where a shield or ground connection is required. Areas with high electrical noise use shielded cable and plugs.

What Is the Boot Cover?

Boot cover is a cable device that protects the connector from bulk cable snags while providing strain relief. It is slid over the RJ45 connector. An advantage of an RJ45 strain relief boot cover is that it completely closes the connection between the connector and the connection. This means that dust can not be added and the chance of malfunctions is reduced. One should first make the boot on the cable and then attach the connector. When you do this in reverse order, the connector can not be put over it anymore.

Things to Consider When Buying Boot Cover for Cat5e, Cat6 and Cat6a Bulk Cables

Cable Diameter

The diameter of the cover’s inner circle cannot be smaller than the cable diameter. Otherwise, the boot cover cannot be slid into the cable. FS provides different sizes of boot cover for bulk Ethernet cables: 5.8mm, 6mm, 6.5mm, 7mm and so on.

Cable Construction

Compared with solid cables which only contain one conductor, stranded cables that consists of several conductors woven together are more flexible. The boot covers for the two types of network cables are different. FS specifies them according to the cable construction for the customers.

Shielded Vs. UnShielded

Shielded bulk cable has an additional shielding jacket around the conductors, so it is thicker than the unshielded one. You must make clear the type of your network cables before buying the boot cover, to avoid unnecessary cost waste caused by improper selection. FS provides boot covers designed specially for the shielded bulk cable.

Structured Fiber Cabling Solutions for Network & Server Cabinet

How does your network or server cabinet look like? Are they stocked with varied servers or networking equipment connected with long cables that reach out to the devices on the other cabinet or enclosure? This is exactly what we used to call point-to-point cabling. However, it is also an art to keep a neat cabling. This article unveils a compelling new cabling method—structured fiber cabling solutions for network&server cabinet.

What Is Structured Cabling and How Does It Matter?

In recent years it has become apparent that fiber-optics are replacing copper wire as an appropriate means of communication signal transmission. The standardized architecture and components for communications cabling formulated by the EIA/TIA TR42 committee—structured cabling is used as a voluntary standard by manufacturers to ensure fiber-optics interoperability. In a structured cabling system, a variety of patch panels and trunk cables are harnessed to create a structure that allows for hardware ports to be connected to a patch panel at the top of the server rack. That patch panel is then connected to another patch panel via a trunk (multi-fiber assembly designed for use in conveyance) in the MDA (Main Distribution Area). When you have several servers, with multiple patch connections and power cords running through your server rack, you need to keep them arranged and managed with an excellent rack cable management system.
structured cabling for server cabinet

Here some may wonder why bother to cost more on the connecting gadgets? Well, without running long patch cords from equipment racks, MACs are much quicker as the cable and port tracing becomes a much easier job. The potential for downtime goes down with the reduced potential for human error. A structured cabling system will look aesthetically pleasing.

Structured Fiber Cabling Solutions for Network & Server Cabinet

In the server room, there may be a server cabinet and a network cabinet for the storage of routers, patch panels, switches and a wide variety of networking equipment as well as networking accessories. Taking FS GR600-series server cabinet and GR800-series network & server cabinet housing 10G and 40G applications as an example, let’s see an exemplary structured fiber optic cabling.

Server Rack to Network Rack

As for intra-rack cabling, say server rack to network rack (10G-40G), connect the 10Gbe switch to a MTP-8 MTP/MPO breakout cassette via a 10GBASE-SR SFP+ transceiver and an LC fiber optic patch cable. Then bridge the cassette with fiber adapter panel which is finally linked to the 40Gbe QSFP+ uplink port on a 10Gbe switch through the MTP trunk cable and a 40GBASE-SR4 QSFP+transceiver. In this respect, the centralized cabling solution keeps cables organized and out of critical airflow paths.

Server Rack to Network Rack

Network Rack to Core Rack

When it comes to network rack to core rack (40G-40G), connect the 40Gbe QSFP+ uplink port on a 10Gbe switch to the FS ultra high density fiber adapter panel with 6 MTP adapters through the MTP trunk cable and a 40GBASE-SR4 QSFP+transceiver. Then draw together two same adapter panels together via an MTP trunk cable. Finally, link the second adapter with the 40Gbe switch by the 40GBase-SR4 QSFP+ MTP/MPO transceiver module and MTP trunk cable. In this way, you can save much energy on tracing each devices.

What Is Open Networking and How Does It Benefit Customers?

Open networking possesses distinct interpretations in different fields. It gradually picked up steam when adopted in open network switching, attracting flocks of vendors to take a share from the giant and burgeoning market. What is open networking? This article facilitates us to have a close look at it.

What Is Open Networking?

Open networking appeals to breaking the tight linkage between the hardware and software. Previously, network switches are sold with hardware and software together. That is to say, if users buy a Juniper EX or MX series network switches, they also buy JUNOS; if customers buy a Cisco Catalyst network switch, they have to buy Cisco IOS. With the advent of open networking, things vary greatly alongside the separation of proprietary hardware from its software. Ethernet switch now lives in a disaggregated world where these elements can be chosen from the most appropriate supplier. Not only hardware and software, but also technical support and accessories are traded respectively.

open networking

How Does Open Networking Impact on Network Switch?

Open network switching hardware was first adopted by tech giants such as Google and Facebook, followed by a slew of enterprises. Besides, Cisco is jumping on the bandwagon of disaggregation in data center networks. It will allow data center customers to run its Nexus operating system (NX-OS) on third-party switches and to use other network operating system on its Nexus switches. Having been backed by several hyperscale companies, open networking drives the network switch to develop in a decentralized way.

How Can Network Users Benefit From Open Networking?


Open network vs. closed network, flexibility wins. As it is stated elsewhere, open means choices and options. You can configure the devices with equipment, software and architecture designs from different vendors. And you can turn down the affiliated OSes that may be feature-rich for you, and refer to those satisfying your rigid demand. Open networking entitles you to the architectural freedom to deploy the best topology and protocols for your environment. This has also fostered innovation dramatically with technologies and practices, allows enterprises to move faster to capture opportunity in the market.


With open networking, you can save budget on dealing with what breaks down rather than throwing away the malfunctioned network switch. That is to say, if open source hardware fails, then you can change it; if software can no longer satisfy your needs, then replace it with other open source software. For example, some people have encountered the issue that the switch whines loudly. In this case, you can decide to make changes only on the hardware. Targeted troubleshooting also saves time and energy.

Unified Development

From the perspective of the vendor, they can jump out of the scenario where they work behind closed doors, and turn to seek common points while reserving difference from others. You want to survive in the market, you need to be open, inclusive and be compatible to the third parties gadgets. A closed system by definition prevents others from openly interfacing with your offer, thus stifling collaboration and increasing the time to market. FS.COM not only released the open networking switch, but also recently sought cooperation with Cumulus Networks to add the leading open source operating system—Cumulus Linux to the FS N-series 40G and 100Gbe switches. This progress brings high-end features like automation to customers.

FS N-series switch, open networking


Open networking represents the general trend. As vendors rush in swarms, customers can stay and wait to reap the benefits. Choose what suits your hardware needs from household names such as FS.COM. This freedom extends to every aspect of your purchase including cables and optics.

Well, common Ethernet switches, also called closed switches, are sold with hardware and software together. That is to say, if you buy a Juniper EX or MX series network switches, you also buy JUNOS; if you buy a Cisco Catalyst network switch, you have to buy Cisco IOS. This is in contrast to bare metal switches which widen the choice available to network buyers. They can choose components like application, network OS, and driver, depending on their own needs. The segregation of hardware and software fulfills the vision of a more affordable, manageable network and saves the time and funding for more projects, which is really beneficial to business.

bare metal switch vs. traditional switch

With a cheap bare metal switch in hand, what about the network operating system? That’s what ONIE (Open Network Install Environment) can do for bare metal switch.

Ins and Outs of ONIE

Introduced by Cumulus Networks, open network install environment (ONIE) combines a boot loader and a small linux operating system. Having been pre-installed on bare metal switches where software and bare-metal hardware are sold separately, customers can freely choose network OS from a range of sources over a network using IPv4, IPv6 and TFTP, or even locally from a USB flash drive. ONIE enables switch hardware suppliers to manage their operations based on a small number of hardware SKUs, enabling a thriving ecosystem of both network hardware and network OS alternatives.

ONIE Paving the Way of Bare Metal Switch

With ONIE, consumers can run any compatible network OS, such as cumulus linux Pica8, and Open Source on the bare metal switch, which dramatically reduces the overall capital and operating cost and breaking through the proprietary traditional network architectures. Moreover, switch & network OS vendors can concentrate on researching and developing switches and operating systems, without being distracted by the minutiae of loading a network OS onto a specific switching platform.

As a component of the open hardware switch platform, ONIE will contribute to advancing standards that define the hardware/software interface. It has now been pre-installed on many bare metal switches, such as FS N8500-48B6C 100gbe switch which also supports current and future network requirements, including an x86- based control plane COM-E with BMC and Timing options for easier integration of automation tools familiar to server administrators. The increasingly mature bare metal switch will in return spur the ONIE to open its arm to more excellent network OS.


Bare metal switch indeed makes our choice flexible and diversified. Moreover, ONIE, presenting an open standards platform for network operating systems, will facilitate the widespread adoption of bare metal switches by making it much easier for administrators to purchase and deploy standards-based network hardware in the same way that x86 servers accept a variety of conventional operating systems.

CMR vs. CMP: When to Use Them in Your House?

Lots of customers have found the letters “CM”, “CMR” and CMP” in the product description when purchasing copper cables like Cat5e cable and Cat6 cable. These terms are the most common cable jacket ratings specified by the National Electric Code (NEC). CM rated cables that are designed for general use won’t be covered in this article. Let’s see the difference between CMR vs. CMP in their applications.

Introduction of CMR vs. CMP

CMR cable stands for “Communications Multipurpose Cable, Riser”. It is also referred to as “riser-rated cable” and designed to prevent fires from spreading between floors through risers or vertical shafts, that is to say, it can self-extinguish when ignited. As for flame-resistance, it does better than the CM cable, so CMR cable can be used where CM cable would be required. Consequently, CMR cable is more expensive than CM cable.


CMP cable stands for “Communications Multipurpose Cable, Plenum”, which is the so-called plenum cable. It is constructed to limit the amount of smoke emitted in case of a fire and prevent flame from spreading to more than five feet. In some places where air travels throughout a building via plenum spaces, it is critical that Ethernet cable is made of the material that doesn’t give off toxic fumes if burned. CMP cable is the one suitable for installation into air plenum spaces.

When it comes to the difference between CMR vs. CMP, as the flammability requirements for CMP cables are stricter than CMR cables, plenum cables can always replace riser cables, but not the reverse. Plenum rated cable is always twice as expensive as riser cable.

CMR vs. CMP: When to Use Them in Your House?

Even though we have read lots of materials telling what is CMR vs. CMP, the knowledge about when to use these cables truly matters for the mass people. Only being applied to the practice, can the theory be tasted. Let’s see the following illustration.
In the picture, the CMP plenum cables run horizontally in the structured ceiling and the dropped ceiling or under a raised floor where is typically considered plenum. This is largely due to the fact that this place is full of fast-moving air as it facilitates air circulation for heating and conditioning systems. The presence of fresh air can bring dander of rapid flame spreading or dangerous gases distribution, thus causing damage to the furniture and threatening people’s lives. Therefore, CMP must be used in air ducts or vents. Typically, it is the prime choice for cabling construction in train station, airport and other public people-intensive places where we must prevent hazards to human health and safety from wiring.

CMR riser cable runs between floors in non-plenum areas as the red line indicates. They are usually run vertically from the basement to the upper floor, so long as the cable does not need to run through an air duct.

CMR vs. CMP in house

CMP, CMR and the like are the NEC’s ratings for the cable jacket. Different types of copper cables like Cat5, Cat5e and Cat6 cables all have CM, CMR, CMP versions. They have the same exact copper inside. The difference is the outer casing or “jacket” that surrounds a cable’s internal wiring and insulation.


This article covers what is riser cable and plenum cable, when to use plenum cable and riser cable. Choosing the right CMR vs. CMP cable is really important. It not only helps prevent dangers but also avoid unnecessary interference by local authorities if you fail to meet the fire codes. If there are any problem or puzzle during cables selecting or application, FS excellent tech team and sales team would like to offer help.

How to Choose MTP/MPO Cable for 10G/40G/100G Connections?

As the data center expands, the traditional fiber optic cables can hardly meet the high requirements for networking, as they not only occupy a large room, but also make it more difficult to manage cables. In contrast, MTP cable and MPO cable provide multi-fiber connectivity in one connector to support higher bandwidth and higher density applications, thus becoming popular. Generally, MTP/MPO cables are classified into three types: trunk cable, harness cable and conversion cable. See what they are and their applications.

Common MTP/MPO Cable Types

MTP/MPO Trunk Cable

MTP/MPO trunk cable is a cable with two MPO or MTP connectors at both ends, with nothing different from ordinary patch cables seen from outside. However, the truth is that the cable usually accommodates 12, 24, 48 and even 72 fibers, and the ends are terminated with 12-fiber or 24-fiber MTP/MPO connectors according to customer’s choice. FS MTP/MPO trunk cables are designed for high density applications which offers excellent benefits in terms on-site installation time and space saving. They are available in multiple lengths and in single mode, multimode OM1, OM2, OM3 or OM4 with LSZH or PVC Jackets. With BIF, FS MTP and MPO  cables are designed for improved bend performance in reduced-radius applications such as residential or office environments which have less bend sensitivity.

MTP/MPO Harness Cable

MTP/MPO harness cable is also known as fanout cable or breakout cable as it has a single MTP connector on one end and on the other end it breaks out into 6 or 12 connectors (LC, SC, ST, etc.). As one fiber patch cord contains two fibers for receiving and transmitting, a 8-fiber MTP-LC harness cable, for example, has 4 LC connectors and an MTP connector at either end. Similarly, a 12-fiber MTP-LC harness cable has 6 LC connectors and a MTP connector. MTP/MPO harness cable is usually deployed for 40G to 10G transmission and 100G to 25G transmission.

MTP/MPO Conversion Cable

MTP/MPO conversion cable has the same fanout design like the MTP/MPO harness cable, but it is terminated with MTP/MPO connectors on both ends. However, the MTP connectors on each end are different in fiber counts and types, which can provide more possibilities for the existing 24-fiber cabling system. It eliminates the wasted fiber, and therefore can largely increase the capacity of the existing 12-fiber and 24-fiber MTP network.

How to Deploy MTP/MPO Cables in 10G/40G/100G Connections?

Follow with the MTP/MPO fiber cables are the MTP/MPO cassettes, MTP/MPO fiber adapter panels and MTP/MPO breakout panels. Here are some typical applications of MTP/MPO fiber cables in 10G, 40G and 100G connections.

10G-10G Connection

In the following two scenarios, two MTP/MPO cassettes installed in the fiber enclosures are connected by MTP/MPO trunk cables, making the core of the cabling simpler. The front panel of the cassettes is connected upwards to server and downwards to 10G ports of FS S5800-48F4S via OM4 fiber optic cable and 10G transceiver.



40G-10G Connection

In this scenario, a 40G QSFP+ port on the FS S5850 48S6Q switch is split up into 4 10G channels. An 8-fiber MTP-LC harness cable connects the 40G side with its MTP connector and the four LC connectors link with the 10G side.


40G-40G Connection

As shown below, a 12-fiber MTP trunk cable is used to connect two 40G optical transceivers to realize the 40G to 40G connection between the two switches. The connection method can also be applied to 100G-100G connection.

120G to 3x40G Connection

In this figure, a MTP/MPO conversion cable connects a CXP 120G SR12 and three 40G QSFP+ SR4 fiber optic transceiver modules to realize the migration from 120G to 40G networking.



High performance, high-density MTP cable, and MPO cable solutions can swap up to 12 traditional fiber connectors with one single small form factor connector, reducing installation time and labor costs. They are suitable for a variety of applications including data centers, telecommunications, broadcast communication, and server rooms. FS strives to provide you with best products with reasonable price and best service.
