The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps

and 550m transmission distance with MMF.

The transceiver consists of three sections: a VCSEL 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
