SFP Transceiver,MM,1310nm,1.25G,2km
Description
SFP Transceiver,MM,1310nm,1.25G,2km
Description
The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps and 2KM transmission distance with MMF.The transceiver consists of three sections: a 1310nm FP LD 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.
