Description

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 120km transmission distance with SMF.

The transceiver consists of three sections: a DFP 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). For further information, please refer to SFP MSA.
