Optical Channel Monitoring Card(OCM) are used for DCI BOX
The main function of the Optical Channel Monitor board (OCM) is to analyze the transmission signal performance of DWDM system in the wavelength range of 1528nm-1567nm, such as co-wave signal spectrum, channel optical power, wavelength and other transmission signals. It has the characteristics of high stability, high sensitivity, accuracy, high dynamic range and short scanning time. It is an indispensable part in the optical performance monitoring of DWDM system.
