Optical performance monitoring and network diagnosis in reconfigurable optical networks

Abstract

We review some of the recent developments of optical performance monitoring (OPM) in various aspects: (i) the enhancement of monitoring resolution, (ii) multi-impairment monitoring, and (iii) OPM network optimization. In particular, some of the studies on the optimization of performance monitoring networks to achieve the optimal monitoring locations and number of monitoring probes are discussed.

The Network Management System of WSS-Styled ROADMs Based on Openflow

“…The OPM module is essential in building a reliable, high-capacity and service-differentiation enabled optical networks [4]. It enables to obtain the parameters of wavelength interval, optical power, channel and so on.…”
