1.25Gbps SFP Transceiver, Single Mode, 20km Reach 1310nm TX / 1490nm RX

Product Description

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

The transceiver consists of three sections: a FB 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 and SFF-8472 digital diagnostics functions.
