Description

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 2.5Gbps and 40km transmission distance with SMF.

The transceiver consists of three sections: a DFB laser transmitter, a APD 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.
