* Up to 2.488Gb/s bi-directional data links
* 1310nm DFB laser and PIN photodetector for 20km transmission
The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 2.488Gbps and 20km transmission distance with SMF.
The transceiver consists of three sections: a 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.
