Abstract
Official abstract text for this publication.
An optical transmission device includes a first power monitor to monitor a first signal into which second signals with respectively different wavelengths are multiplexed so as to measure received power of the first signal; an amplifier to amplify the first signal, to generate a third signal; a driver to drive the amplifier; a demultiplexer to separate the third signal into fourth signals with the different respectively wavelengths; second power monitors each to monitor each of the fourth signals so as to measure received power of each of the fourth signals; a memory to store therein data related to gain in the amplifier, the data corresponding to each of wavelengths of the second signals, with respect to parameters which are the received power measured by the first power monitor and driving condition; and a processor to calculate power of each of the second signals.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical transmission device comprising: a first optical power monitor configured to monitor a first optical signal, the first optical signal being a multiplexed signal received by the optical transmission device into which a plurality of second optical signals with respectively different wavelengths are multiplexed, the first optical power monitor obtains a received power of the first optical signal; an amplifier configured to amplify the first optical…
