Optical performance monitoring (OPM) is the estimation and acquisition of different physical
parameters of transmitted signals and various components of an optical network. OPM …

Publisher Summary This chapter explores optical performance monitoring (OPM) and its
potential for enabling higher stability, reconfigurability, and flexibility in a self-managed …

Today's optical networks function are in a fairly static fashion and are built to operate within
well-defined specifications. This scenario is quite challenging for next generation high …

The rapid growth of packet based Internet traffic and big data, associated with
interconnected Data Centers (DC) and High Performance Computing (HPC) systems have …

This paper investigates the fault-diagnosis problem for all-optical wavelength-division-
multiplexing (WDM) networks. A family of failure-localization algorithms that exploit the …

The invention relates to a method for detecting a check-back signal in a transmission system
for optical signals. According to said method, a constant proportion of the output in a defined …

Feature Issue on Optical Performance Monitoring (OPM) We report on the pilot-tone-based
optical performance monitoring techniques for use in the wavelength-division multiplexing …

The sustainable growth of high-bandwidth services and on-demand applications has
introduced new challenges to next-generation networks in terms of capacity, configurability …

We report on the performance comparisons of the chromatic dispersion-monitoring
techniques using pilot tones. The results show that the monitoring technique using phase …
