SFP28 SR Optical Transceiver

HW Compatible 25GBASE SR Optical Transceiver SFP28 DFB 1310nm


HW Compatible 25GBASE-SR SFP28 850nm 100m DOM LC MMF Ethernet Optical Transceiver



This Ethernet Optical 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.
