SFP 155Mbps up to 120km et 200km transmission distance with DDM.
The SFP transceivers are high performance, cost effective modules supporting data-rate of 155Mbps up to 120km, 200km transmission distance with SMF.The transceiver consists of three sections: a uncooled 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.
