2.5G SFP Dual Fiber 1550nm DFB Up to 40km on SMF SFP Optical Transceiver Module
Features
Commercial : 0 to +70°C
Industrial : -40 to +85°C
Applications
Description
The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 2.5Gbps and 40km transmission distance with SMF.
The transceiver consists of three sections: a DFB laser transmitter, a APD 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.
