1.25G Lc Connector 20Km Single Bidirectional Optical Transceiver

Bidirectional Fiber Optic Transceiver 1.25G Lc Connector 20Km Single Fiber Sfp Module

Description

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.
