Description
　The SFP transceivers are high performance, cost effective modules supporting data-rate of 155Mbps and 150km transmission distance with SMF. The transceiver consists of three sections: a DFB laser transmitter, an 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.
