With the development of data centers and the improvement of broadband, optical transceivers play an increasingly important role. It is understood that after years of development, optical transceivers have increased from a rate of 10G to 200G, and packaged from a 1X9 packaged optical module to the mainstream QSFO28 optical transceiver package. Each development has a new rate and a new package. In the family of optical transceivers, there is such an optical module-SFP28 optical transceiver. Today UnitekFiber will introduce SFP28 optical transceiver products, applications and solutions.
SFP28 is an optical transceiver packaging method in the optical transceiver family. So, how was the 25G SFP28 optical transceiver born?
We know that energy saving and cost are two important factors that need to be considered when deploying a network in a data center. In addition, the price of 40G optical transceiver and 100G optical transceivers is too high, the power consumption is too large, and the speed of 10G optical transceivers cannot meet network requirements. Therefore, the 25G SFP28 optical transceiver was born under this situation, which just made up for the shortcomings between the three, and greatly improved the port density, reduced the network deployment cost, and the power consumption was relatively low.
How many types of 25G SFP28 optical transceivers do you know?
25G-LR 1310nm 10km SFP28 optical transceiver module
This 25G-LR 1310nm 10km SFP28 optical transceiver is an SFP28 packaged hot pluggable optical transceiver module that supports 25Gbps data rate. It is a high-performance transceiver module for short-distance data, supporting communication and interconnection applications, with a 25.78125 Gbps transmission distance of up to 10 kilometers. This transceiver module mainly uses the operation of a single-mode fiber system with a nominal wavelength of 1310nm. The optical interface adopts double LC sockets.
25G-SR 100m SFP28 optical transceiver
25G-SR 100m is a single channel, pluggable fiber SFP28 optical transceiver for 25 Gigabit Ethernet and Infiniband EDR applications. It is a high-performance short-distance data communication module using OM3 fiber or using OM4, interconnecting applications running at 25.78125Gbps up to 70m fiber. This transceiver module is designed to use a multimode fiber system with a nominal wavelength of 850nm. The electrical interface uses 20 contact edge type connectors. The optical interface uses a two-phase LC ports.
So far, we have learned about 25G-LR 1310nm 10km SFP28 optical transceiver and 25G-SR 100m SFP28 optical transceiver. However, the 25G SFP28 optical transceiver mentioned above is only a single product. Then, what is the combination of 25G SFP28 optical transceiver application? Where is it applied? Here are the two products to be introduced below: 25Gbps 850nm multi-mode SFP28 AOC Active Optical Cable and 25GE SFP28 DAC Direct Attach Copper (DAC) cable.
25Gbps 850nm multimode SFP28 AOC active optical cable
SFP28 active optical cable(DAC) is an SFP28 connector that directly connects optical fiber components. They are suitable for short distances and provide a cost-effective way to connect between racks and adjacent racks.
25Gbps SFP28 AOC is a single-channel, pluggable optical SFP28 for 25 Gigabit Ethernet and Infiniband EDR applications. It is a high-performance transceiver module for short-distance data communication and interconnection applications, using 100meters long OM4 or OM3 fiber cable, And operating at 25.78125 Gbps up to 70m. This transceiver module is designed to use a multimode fiber system with a nominal wavelength of 850nm. The electrical interface uses 20 contact edge type connectors.
25GE SFP28 DAC direct attach passive copper cable
UnitekFiber’s 25GE SFP28 passive copper cable can provide customers with 25Gb/high-bandwidth data interconnection capabilities. It complies with IEEE P802.3by Ethernet standard and SFF-8402 SFP28. This product is widely used in the data center or supercomputing center system.
