Optical Channel Monitor

Optoplex Optical channel monitor (OCM) uses proprietary thin-film interference filter technology combined with a micro-actuator and high-speed electronics. Optical channel monitor is used to measure critical information data on optical transmission signals in DWDM networks for monitoring signal dynamics, determining system functionality, identifying performance change, and providing feedback for controlling network elements so as to optimise operational performance. In particular, Optoplex Optical channel monitor can automatically scan the C-, L- or C+L-band wavelength range and precisely measure channel wavelength, power, and optical signal-to-noise ratio (OSNR). See the following schematic diagram for OCM working principle.Features
