Description
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 information, please refer to SFP MSA.
