Abstract
Official abstract text for this publication.
Multiple receivers are comprised in a flexible coherent transceiver of a multi-span optical fiber network. Each of the multiple receivers is operative to handle communications on a respective channel. The multiple receivers measure optical characteristics. For each of the multiple receivers, the optical characteristics include optical nonlinear interactions on the respective channel, the optical nonlinear interactions being at least partially dependent from one span to another span. An optical power of a signal on each of the multiple channels is adjusted as a function of the optical characteristics.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of power control in a multi-span optical fiber network, the method comprising: measuring optical characteristics in multiple receivers comprised in a flexible coherent transceiver of the multi-span optical fiber network, each of the multiple receivers operative to handle communications on a respective channel; and adjusting an optical power of a signal on each of the multiple channels as a function of the optical characteristics, wherein for eac…
