SFP28
- inherits all the benefits and appearance of the SFP+, but supports an enhanced data rate of a maximum 25Gbps to 28Gbps
- it is the third generation of SFP connection systems built for 25G throughput following the IEEE 802.3by specification (25GBASE-CR)
- typically targets 25G Ethernet, CPRI, and wireless base station applications
- depending on the application, the SFP28 transceiver can be divided into six broad categories:
- Regular SFP28
- BiDi SFP28
- CWDM SFP28
- DWDM SFP28
- SFP28 DAC
- SFP28 AOC
