SFP20SMLC 1.25G SFP SM LC 20KM MODULE DUAL FIBRE 1310NM

DESCRIPTION

OVERVIEW

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 20km transmission distance with SMF.
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.
