Description
- The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and 20km 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.
