Product details:

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps.

The transceiver consists of three sections: a FP(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.
