1.25G SM Single Fiber BIDI 1310/1550nm 20KM SFP Module
The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of
1.25Gbps/1.0625Gbps and 2km transmission distance with SMF.
The transceiver consists of three sections: a FP 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 (MSA) and SFF-8472. For further information,
please refer to SFP MSA.
