Optical Processing for Performance Monitoring
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2011, 2011We review recent experiments of waveform spectrum analysis by the nonlinear Kerr effect, and its application to multi-impairment monitoring of optical signals. The measurement of 640 Gb/s signals via nonlinear fibers and planar waveguides is compared.

Optical domain performance monitoring
Optical Fiber Communication Conference. Technical Digest Postconference Edition. Trends in Optics and Photonics Vol.37 (IEEE Cat. No. 00CH37079), 2002The rapid evolution of terrestrial optical networks is driving the need for optical domain performance monitoring in order to provide the lowest transport cost per managed bit. This paper presents various techniques for monitoring optical signals between 3R interfaces in terms of their economic value to the network operator.

Performance degradations and monitoring in optical networks
SPIE Proceedings, 2004nonlinearities [1]. Typically, systems are designed such that these degrading effects are eitherminimized or compensated (e.g., using compensation fibers and devices). It has been widelyrecognized that as domains of transparency get larger, data rates of 10 Gb/s and higher becomemore common, and channel spacings are reduced, physical impairments will ...

Performance Monitoring in Optical OFDM Systems
Optical Fiber Communication Conference and National Fiber Optic Engineers Conference, 2009We investigate performance monitoring within coherent optical OFDM systems. Estimates for CD and instantaneous DGD can be extracted from the result of channel estimation. The method can also provide information about OSNR and non-linear distortion.

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.

Monitoring the performance of a semiconductor optical amplifier
Applied Physics Letters, 1990Measurements of optical gain and spontaneous emission of optical amplifiers show that the latter is a good measure of the former. A device structure is fabricated where a photodetector is integrated next to the amplifier. A fraction of the spontaneous emission from the amplifier impinges on the photodetector in this device producing a photocurrent. The

Asynchronous Sampling for Optical Performance Monitoring
OFC/NFOEC 2007 - 2007 Conference on Optical Fiber Communication and the National Fiber Optic Engineers Conference, 2007We 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.
