Description

 

The SFP transceivers are high performance, cost effective modules supporting 155Mbps data-rate and 120km transmission distance with SMF.

 

The transceiver consists of three sections: an uncooled 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.
