Optical performance monitoring in optical packet-switched networks [PDF]

, 2015
Para poder satisfacer la demanda de mayores anchos de banda y los requisitos de los nuevos servicios, se espera que se produzca una evolución de las redes ópticas hacia arquitecturas reconfigurables dinámicamente. Esta evolución subraya la importancia de ofrecer soluciones en la que la escalabilidad y la flexibilidad sean las principales directrices ...

Performance monitoring techniques supporting cognitive optical networking [PDF]

2013 15th International Conference on Transparent Optical Networks (ICTON), 2013
High degree of heterogeneity of future optical networks, such as services with different quality-of-transmission requirements, modulation formats and switching techniques, will pose a challenge for the control and optimization of different parameters.

Optical Performance Monitoring Systems in Disaggregated Optical Networks [PDF]

2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
In this paper, optical performance monitoring is presented as enabler to address the key challenges in disaggregated optical networks. In fact, data plane elements for non-intrusive monitoring of different modulation formats will be discussed, reviewing different options based on high resolution spectral analysis.

Applications of polymer optical fibre grating sensors to condition monitoring of textiles [PDF]

, 2009
Fibre Bragg gratings (FBGs) in polymer optical fibres (POFs) have been used to measure the strain in a woven textile. FBGs in both POFs and silica optical fibres were attached to a woven textile specimen, and their performance characterised.

A study to trial the use of inertial non-optical motion capture for ergonomic analysis of manufacturing work [PDF]

, 2016
It is going to be increasingly important for manufacturing system designers to incorporate human activity data and ergonomic analysis with other performance data in digital design modelling and system monitoring. However, traditional methods of capturing

A Novel Monitor Placement Algorithm for Accurate Performance Monitoring in Optical Networks [PDF]

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2011, 2011
We propose a novel monitor placement algorithm that reduces significantly the number of monitors required to accurately assess the QoT of all lightpaths established in an optical network, compared to other monitor placement methods.

Optical Labels Enabled Optical Performance Monitoring in WDM Systems

Photonics, 2022
Optical performance monitoring (OPM), particularly the optical power and optical signal-to-noise ratio (OSNR) of each wavelength channel, are of great importance and significance and need to be implemented to ensure stable and efficient operation/maintenance of wavelength division multiplexing (WDM) networks.

Optical Performance Monitoring in Mode Division Multiplexed Optical Networks [PDF]

Journal of Lightwave Technology, 2021
This article considers, for the first time, optical performance monitoring (OPM) in few mode fiber (FMF)-based optical networks. 1-D features vector, extracted by projecting a 2-D asynchronous in-phase quadrature histogram (IQH), and the 2D IQH are proposed to achieve OPM in FMF-based network.
