Transceiver 850nm WDM coupler module

Basic Info

Model No.: SFP-125-85-S055

Product Description

* Transceiver 850nm WDM coupler module Description


1.The sfp transceivers are high performance, cost effective modules supporting dual data-rate 1.25gbps and up to 120km transmission distance with SMF.


2.The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.



3.The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
