Fibre Channel SFP: Why Fibre Channel?

With the advent of SFP transceiver communication, there have been many different standards. In network hardware, the advantage of SFP transceivers is that they allow a single device, such as a switch, to support different cabling and transmission formats. However, when you try to find out which optical transceiver type you need, you will encounter problems. Because there are several different types of fiber SFP that can support a variety of communication standards, such as CWDM/DWDM, SONET, fibre channel, Fast Ethernet, and Gigabit Ethernet. Today we are going to introduce fibre channel SFP.

What Is Fibre Channel?

Fibre channel is a protocol mainly used for “storage area network”. Fibre channel speeds are different, ranging from 1, 2, 4, 8, 16Gbps to 128Gbps. Fibre channel is a lossless protocol developed when switches are not as reliable as they are now. When using Ethernet as a protocol, frames are discarded, which brings problems to applications such as data traffic. With the development of technology, switches are now becoming more reliable. However, fibre channels still have a small advantage over Ethernet in terms of consistency and latency.

What Is Fibre Channel SFP?

Fibre channel SFP transceivers is an important device for connecting fibre channel networks in data centers. It provides an interface between fibre channel system and SAN optical fiber. Fibre channel SFP transceiver is a common module in storage area network (SAN), which can provide 1, 2, 4, 8, 10, 16 and 20Gbps data transmission rate. Fibre channel SFP transceiver can be used for single-mode and multimode fiber applications.

Fibre Channel SFP: Why Fibre Channel?

Fibre channel, as a set of advanced data transmission standards, allows large amounts of data to be reliably moved at thousands of megabits between computers, servers, disk arrays, and other devices. Fibre channels are chosen for high-end storage connections because they have three main advantages: high speed, proven reliability, and guaranteed ordered packet transmission.

  • High speed: The original version of the fibre channel runs at the maximum data rate of 1Gbps. Now it can run at the rate of 128Gbps.
  • Proven reliability: fibre channels were initially accepted by almost all the world banks, Fortune 500 companies, and other organizations. These enterprises and organizations needed reliable and timely data transmission no matter how much it costs. Nowadays, the reliability of data transmission is still crucial. fibre channels are the most reliable for any enterprise or organization. Moreover, the choice of the fibre channel is not expensive.
  • Guaranteed in-order delivery: Fibre channel ensures that the raw block data is transmitted sequentially. Sequential delivery greatly improves network efficiency and is required by some applications, such as video streaming and IP streaming. Fibre channel naturally streams video frames sequentially, eliminating the bottleneck of reorganization. Otherwise, the frame speed per second required for video will be reduced seriously.

Conclusion

In summary, the advantages of fibre channel are still abundant, such as fast speed, reliability and sequential delivery, which is why we advocate fibre channel SFP. You can find high-quality FC SFP on FS.COM, such as 2G/4G FC SFP, 8G/10G FC SFP + module. Besides, we can also supply Gigabit SFP, 40G QSFP+ and 100G QSFP28. We offer a full range of branded and reasonably priced 100% compatible transceivers to meet your business need.

Cable Management Bar: What Role It Plays In Rack Cable Management

I think it’s safe to say that in most data centers or server rooms, cable clutter is an annoying issue that’s hard to ignore. In recent years, more and more data centers and server rooms feature high density and large capacity, usually accompanied by a large number of copper cables or fiber optic patch cables to connect the entire network. If you want to ensure the performance of the entire network, then there is no doubt that links to patch cable cannot be wrong. Any incorrect cable management will directly lead to cable damage and network failure, resulting in data transmission errors, performance problems, and system downtime. Today, our topic is cable management bar, a super important tool in rack cable management.

Rack Cable Management

Our commonly used cable management solution is rack cable management. Rack cable management is an economical cable management solution, suitable for the daily use of telecommunication room, computer room and laboratory space. The five main cable management solutions are horizontal rack, vertical rack, cable hanger and pallet, data wiring rack and fiber optic wiring rack.

As well known that rack mount enclosure, cable rack (such as copper and fiber distribution frames), cable lacing and J-Hook can achieve better cable management in high-density networks. In addition to these tools, are there other tools needed to achieve good cable management? The answer is the cable harness and cable management bar. Here, let’s look at the cable management bar. It is very important for rack cable management.

What Is Cable Management Bar

Cable management bar is made of metal, which is designed to be installed above, below, behind, or in front of your rack, so as to facilitate placement between racks (between switches and wiring racks) or cabinets. With the support of the bar, the pressure of cable connections will be greatly relieved. The installation of the cable management bar is pretty easy. Users only need several screws to fasten each end of the bar onto the rack.

Advantages of Cable Management Bar

What makes the cable management bar so widely used to manage patch cables? What are the advantages of the bar when it is compared with other cable management tools?

  • First, if we use the cable management bar to manage patch cables, we can save a lot of space. Because it uses less than 1U of space. Or if installed in front of or behind a rack, cable management bar does not take up any space. Therefore, we can save valuable space for installing other network devices.
  • Secondly, using a cable management bar can reduce the strain of the cable. When users install large amounts of cables in the rack, cable stress will increase accordingly. Using the bars can relieve cable stress and avoid pulling cables when routing them from one side of a rack to the other. This plays an important role in the high-density cabling network.
  • Third, the cable management bar can promote the bending radius of patch cables, thereby reducing or even avoiding risks such as slower data transmission rates or damaged patch cables.

Conclusion

As we move to more and more complex networks, cable management plays an unprecedented role. Cable management bar has the edges of reducing the pressure caused by cable connection, increasing the bending radius of patch cables and saving space. It is an ideal choice for efficient and tidy cable routing, and it is also an important part of the rack cable management. Therefore, if your network features high density and large capacity, it is best to select the appropriate type of cable management bar to manage your patch cables.
