Optoplex Optical channel monitor (OCM), also known as Optical performance monitor (OPM), uses proprietary thin-film interference filter technology combined with a micro-actuator and high-speed electronics. Optical channel monitor / Optical performance 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 controling network elements so as to optimize operational performance. In particular, Optoplex Optical channel monitor / Optical performance monitor can automatically scan the C-, L- and/or C+L-band wavelength range and precisely measure channel wavelength, power, and optical signal-to-noise ratio (OSNR) with a 60 dB dynamic range. See the following schematic diagram for OPM working principle.
Operating through a continuous wavelength scan and built-in wavelength reference with optical tunable filter technology, Optoplex's Optical channel monitor / Optical performance monitor has a high wavelength accuracy and resolution with a low channel cross-talk. Built with Optoplex's high-isolation and wide passband thin-film filter and assembled together with high-grade single detector, Optoplex's Optical channel monitor / Optical performance monitor increases channel power measurement accuracy and dynamic range. Using an innovative optical design and high-grade single-element InGaAs detector, channel OSNR measurement range is increased to >30 dB. Further, the Optical channel monitor / Optical performance monitor includes a built-in filter driver and PCB to control and interface with all data-processing electronics. DPRAM, RS-232, or USB interfaces are available and can be customized to meet specific requirements. Optoplex's Optical channel monitor / Optical performance monitor has passed Telcardia GR-468-CORE tests. Moreover, the Optical channel monitor / Optical performance monitor device features compact size and low cost.
1. Certain parameter specs can be varied based on customer demands. 2. Optional feature. Its values at lower input power level are limited by noise floor. 3. Including PCB. |
