SFP28 is an enhanced version of SFP+ and has the same common form factor. 25G SFP28 transceiver includes SR, LR Lite, LR, ER, etc, adopt LC interface and the SFP28 specification is compatible with IEEE802.3by, IEEE802.3cc, SFF-8472 and other standards.
SFP28 supports speed of 25Gb/s over a single lane and provides a new way for networking upgrade: 10G-25G-40G-100G, which is an energy-efficient solution to meet the growing demands of next-generation data center switch. They have the characteristics of low power consumption, high speed and high reliability and mainly applied in 25G Ethernet, CPRI10 and other environments.
