Product description

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of
1.25Gbps/1.0625Gbps and 20km transmission distance with SMF.
 
The transceiver consists of three sections: a FP 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.
