155M SFP Bi-di Single Fiber Transceiver Module 20km to 120km
Overview
Newbridge® 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 or 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.
