Optical Performance Monitor

OPM01CX An optical performance monitor (OPM) is a device that is used in a dense wavelength division multiplexed (DWDM) network to monitor the quality of signals within the fiber optic network. In fiber optic networks, data is provided to network service provider in the form of optical signals modulated at individual wavelength channels transmitted along a fiber optic cable. With current WDM technology a plurality of different single wavelength modulated optical data signals propagate within a same fiber. Ideally each of these single wavelength modulated optical data signals is individually monitored in these WDM systems to ensure a certain signal quality.
