Asynchronous Sampling for Optical Performance Monitoring

OFC/NFOEC 2007 - 2007 Conference on Optical Fiber Communication and the National Fiber Optic Engineers Conference, 2007
We present two novel performance monitoring techniques for optically switched networks, based on asynchronous multi-tap sampling. We show that multiple simultaneous impairments can be separated and quantified by a single monitor.

Convolutional Neural Networks for Optical Performance Monitoring [PDF]

2019 IEEE Avionics and Vehicle Fiber-Optics and Photonics Conference (AVFOP), 2019
We demonstrate accurate OSNR estimation using convolutional neural networks based on the constellation image of a QAM signal. Simulation and experiment results demonstrate estimation error within 0.1 dB. Neural network training on simulated and successful testing on experimental data was also demonstrated.

Optical performance monitoring in elastic optical OFDM networks

2015 International Conference on Photonics in Switching (PS), 2015
Optical performance monitoring (OPM) is a crucial element in network management, in order to assure the quality of the optical signals at various intermediate and destination nodes. In future elastic optical network, the network operation is more adaptive and reconfigurable.

Sensitivity issues of optical performance monitoring

IEEE Photonics Technology Letters, 2002
Optical performance monitoring is becoming an important network building block as the system becomes increasingly sophisticated and the network span becomes larger and larger. The general requirement for the optical performance monitor from the noise perspective is derived from the fundamental considerations of detector noises.
