Optical signal to noise ratio monitoring based on optical filtering effects in high-speed optical transmission systems
2015
Optical signal to noise ratio (OSNR) monitoring is an important topic of optical performance monitoring. A robust OSNR monitoring scheme is desired for management of dynamic optical networks. In this paper, our OSNR monitoring methods based on optical filtering effects are reviewed, which exhibit the merits of dispersion insensitivity, low cost, and simple operation.
