1.25Gbps 1550nm 40km SFP Optical Transceiver

General Details

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 40km transmission distance with SMF. The transceiver consists of three sections: 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.
