PROCESSING OF OPTICAL PERFORMANCE DATA IN AN OPTICAL WAVELENGHT DIVISION MULTIPLEXED COMMUNICATION SYSTEM

摘要

Optical performance measurements are taken in an optical network and display ed in a form that allows an operator to enter fault information related to eh measurements, or to automatically generate fault alarms to the operator, bas ed on processing of the measurements. The optical measurements may be individua l power measurements taken for each light-path at various points in each node it traverses, such as amplifiers/demultiplexers or at an interface with another node.
