The LumaOptics DWDM-XFP-ZR+-XX 120km XFP Transceiver exhibits excellent wavelength stability, supporting operation at 100 GHz channel, cost effective module. It is designed for 10G SDH/SONET and 10G Ethernet applications. The transmitter section incorporates a colded EML laser, and the receiver section consists of a APD photodiode integrated with a TIA, Integrated low power dual CDR with Electronic Dispersion Compensation (EDC). This module can be used to compensate channel impairments caused by either single mode fiber up to 120 km .All modules satisfy class I laser safety requirements. The LumaOptics XFP 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.
