2.488G CWDM SFP Optical Transceiver, 80km Reach
Description
The SFP transceivers are high performance, cost effective modules supporting data-rate of 2.488Gbps
and 80km transmission distance with SMF.
The transceiver consists of three sections: an uncooled CWDM DFB laser transmitter, a PIN or 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.
