Flexgrid High Resolution Optical Channel Monitor (FOCM)

Perform advanced monitoring of spectral features, including valid channel detection, optical power, and OSNR, and determine center wavelength with sub-GHz frequency accuracy.

The FOCM gives you optical spectrum analyzer (OSA) performance in an ultra-compact, cost-effective, optical networking component. It provides excellent power accuracy independent of adjacent signal power and can rapidly scan the entire C-band in real-time.


Use the FOCM for monitoring in conventional or mixed modulation formats. Get high-accuracy measurements thanks to our patented coherent detection technology.
