Overview

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 DFB 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
