How Many Types of 25G SFP28 Optical Transceivers Do You Know?

With the development of data centers and the improvement of broadband, optical transceiver 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.
