1.25Gbps 120km DWDM SFP Optical Transceiver

1.25Gbps SFP, 120KM, 45-CH DWDM Wavelengths, duplex fiber, LC, single mode

General Details

The DWDM SFP Transceiver exhibits excellent wavelength stability, supporting operation at 100 GHz channel, cost effective module. It is designed for DWDM SONET/ SDH, Gigabit Ethernet and Fiber- Channel applications.


The transceiver consists of two sections: The transmitter section incorporates a cooled DFB laser. And the receiver section consists of a APD photodiode integrated with a TIA. All modules satisfy class I laser safety requirements. This DWDM SFP transceiver provides an enhanced monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage, laser temperature and TEC current.
