    1.25G Bidi Fiber Optic SFP Module SC Connector 20Km Gigabit Optical Transceiver

    1.25G Bidi Fiber Optic SFP Module SC Connector 20Km Gigabit Optical Transceiver


    SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and
    120km 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.


    ●Supports 1.25Gbps/1.0625Gbps bit rates
    ●Bi-Directional SC/PC connector
    ●Hot pluggable SFP footprint
    ●1490nm DFB laser and 1550nm APD photo detector
    ●1550nm DFB laser and 1490nm APD photo detector
    ●Applicable for 120Km SMF connection
    ●Low power consumption, < 1.0W
    ●Digital Diagnostic Monitor Interface
