OCM Card

The DWDM Multi-Channel Monitoring Board, also known as OCM (Optical Channel Monitor), is designed to enable online monitoring of the center wavelength, power level, signal-to-noise ratio, and number of optical channels in the system. It reports the monitored wavelength, power level, and number of optical channels to the main control board for processing. It allows the system to monitor different points along the routes, making it easier and more convenient for the system to detect alarms and locate faults.


Product Features

  • OCM supports spectral analysis of 1/4/8-channel signals.
  • Completes channel monitoring, analyzes channel status data, and generates power addition and power drop alarms.
  • Monitors and reports optical power, center wavelength, signal-to-noise ratio, and number of wavelengths.
  • Communicates with the main control board and receives control instructions from the main control board.
  • Utilizes optical switching for selecting the direction of the optical path.
