SFP05MMLC 1.25G SFP MM LC 550M MODULE DUAL FIBRE 850NM

DESCRIPTION

OVERVIEW

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 550m transmission distance with MMF.
The transceiver consists of three sections: a VCSEL lasertransmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.
