Abstract

Optical performance measurements are taken in an optical network and displayed in a form that allows an operator to enter fault information related to eh measurements, or to automatically generate fault alarms to the operator, based on processing of the measurements. The optical measurements may be individual 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.
