Optical Monitoring Modules

Optical Channel Monitors – OCM Series

The OCM Series of optical channel monitors are ideal for high-capacity multi-degree ROADM applications. They can be configured via software commands to operate in scanning or dwelling mode. In scanning mode, the OCM performs flexible-bandwidth channel monitoring function with fine frequency granularity using an integrated frequency reference. The rich set of spectral data resulting from one measurement is transferred over a high-speed serial peripheral interface (SPI) to virtually eliminate measurement latency. In dwelling mode, the OCM 2580 provides access to a high bandwidth photocurrent signal to enable advanced signal analysis on a selected channel.
