HW Compatible 25GBASE SR Optical Transceiver SFP28 DFB 1310nm
HW Compatible 25GBASE-SR SFP28 850nm 100m DOM LC MMF Ethernet Optical Transceiver
Descriptions
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.

Notes:
1. Average power figures are informative only, per IEEE 802.3cc.
2. Measured at the BER less than 5E-5, back to back. The measure pattern is PRBS 231-1 with worst ER=4.5@ 25.78Gb/s.
High Performance and Reliability
* Low power consumption＜1W, saving power
* Stainless steel material, anti-corrosion, and salt spray resistance
* DDM for real-time monitoring supply volt, temp, bias current, and TX & RX power
