DeSCRJPTion
The ESFP transceivers are high performance, cost effective modules supporting multi-rate of 155Mbps~2.67Gbps and 80km 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.
