Frequently Asked Questions

SFP28 Transceivers and Cables

What are the types of 25G SFP28 optical transceivers?

There are 3 types of 25G SFP28 transceivers: 25G SFP28 standard transceiver(SR, LR, ER), 25G BiDi SFP28 transceiver, and 25G WDM SFP28 transceiver(CWDM, DWDM, LWDM).

What are the applications of different 25G SFP28 transceivers?

25G SFP28 typical transceiver (SR, LR, ER, and BIDI) are mainly used to interconnect servers, switches, and routers in data centers.
25G CWDM SFP28 transceiver is a single-mode duplex CWDM module, mainly applied to switches, routers, NICs, and storage network devices of 25G Ethernet.
25G DWDM SFP28 optical module is mainly used to meet the requirements of 5G pretransmission services. The device adopts the EML+APD scheme, with the transmission distance of up to 10km through single-mode fiber.
25G LWDM SFP28 is a stable and cost-effective solution in 5G prequel networks. It adopts a high-performance and low-cost DML laser to provide 12-wave multiplexing, and makes up for the problems of large dispersion of 25G CWDM module and high cost of 25G DWDM optical SFP module laser.

Can SFP28 Modules Operate at 10 Gbps Speeds?

Yes, SFP28 modules can operate at 10 Gbps speeds. However, their performance at this reduced data rate depends on the specific module and the equipment it's connected to. It's necessary to consult the manufacturer's specifications to ensure proper functionality
