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.

Artificial intelligence based optical performance monitoring
Journal of Optical Communications, 2021AbstractIn this paper, a technique for optical performance monitoring (OPM) using deep learning-based artificial neural network (ANN) is implemented. ANN is trained with parameters derived from eye-diagram for the identification of optical signal to noise ratio (OSNR), chromatic dispersion (CD) and polarisation mode dispersion (PMD) simultaneously and ...

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 performance monitoring in elastic optical OFDM networks
2015 International Conference on Photonics in Switching (PS), 2015Optical 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.

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.

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.
