80km 1.25g LC Fiber Optic CWDM SFP Optical Transceiver

Product Description

80km 1.25G LC Fiber Optic CWDM SFP Optical Transceiver

 

The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps and 80km transmission distance with SMF.
 
The transceiver consists of three sections: an uncooled CWDM 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.
