The EON-OMP-OCM Interface card measures the optical spectrum, channel power, channel wavelength, channel OSNR, and total power on the monitored fibre. The EON-OMP-OCM module is a component of Prolabs’ EON-OMP-2 platform and uses a tunable optical filter to de-multiplex and monitor 1529nm-1561nm, 100/50 GHz spaced optical channels.
