Abstract
Official abstract text for this publication.
An apparatus and method of failure detection in optical amplifier is disclosed. The optical amplifier includes an optical amplifying fiber configured to receive input light so that the input light travels through the optical amplifying fiber, an excitation light generator configured to supply excitation light to the optical amplifying fiber to optically amplify the input light as the input light travels through the optical amplifying fiber, and a processor configured to determine whether a failure has occurred in the optical amplifier, based on a change in power of the excitation light and a change in power of the input light.
First claim
