25G SFP28 SR Transceiver (MMF, 850nm, 100m, LC, DDM)
The SFP28 transceiver adopts LC duplex connectors, reaching a link up to 100m over OM4 MMF (70m over OM3). The SFP28 transceiver module supports running on the same 1G/10G network cabling Infrastructure, giving 2.5 times increase in speed at least, and the built-in DDM/DOM functions monitor the real-time operating status. Each SFP28 transceiver module is individually tested on a series of Generic switches, and is fully compliant with the SFP28 MSA, RoHS, CPRI, and the eCPRI standards. Featuring low power consumption, high speed, this 25G transceiver is ideal for 25G Ethernet, telecom, and data center.
