Optical performance monitoring with tunable narrowband optical filtering

open access: goldOptics Express, 2005
We propose an optical performance monitoring scheme that combines a tunable narrowband optical filter with asynchronous histograms to create density plots that represent probability maps of both optical power and frequency. Simulations are used to investigate the technique, and show that measurements at transmitters and filters can directly detect ...

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

open access: greenOptical 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 performance monitoring in coherent optical OFDM systems

open access: goldOptics Express, 2007
Optical performance monitoring is an indispensable feature for optical systems and networks. In this paper, we propose the concept of optical performance monitoring through channel estimation by receiver signal processing. We show that in coherent-optical-orthogonal-frequency-division- multiplexed (CO-OFDM) systems, critical optical system parameters ...
