Specifications

            1.25Gbps SFP Bi-Directional Transceiver, 20km Reach1310nm TX / 1490 nm RX

 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.
