Channel Monitoring (OCM)

  • ocm 2

The optical channel monitoring card (OCM) launched by Sintai Communication is mainly used to analyze the performance of the MUX signal spectrum, channel optical power, wavelength and other transmission signals in the wavelength range of 1528nm-1567nm of DWDM system. It has the characteristics of high stability, high sensitivity, accuracy, high dynamic range and short scanning time. It is an indispensable and important part of optical performance monitoring in DWDM system.
