Transceiver 25Gbps SFP28 optical Transceiver Multi Mode 850nm 100m Reach
Description
The SFP28 transceivers are high performance, cost effective modules supporting data rate of 25.78Gbps and 70m transmission distance with OM3 MMF or 100m transmission distance with OM4 MMF.
The transceiver consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.
The transceivers are compatible with SFP Multi-Source Agreement and SFF-8472 digital diagnostics functions.
