    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
