Abstract

<B>"REDE DE COMUNICAçãO óPTICA E PROCESSO DE CORRIGIR A FAL;HA DE UM ENLACE DE FIBRA óPTICA EM UMA REDE DE COMUNICAçãO óPTICA"<D>. Uma rede de comunicqação óptica transparente que assegura a proteção do canal de comunicação principal de cada comprimento de onda suportado e suporta tráfego ocasional em um canal separado. No caso de uma disrupção ou degradação no canal principal, estas comunicações são redirecionadas para o canal ocasional.<B> "OPTICAL COMMUNICATION NETWORK AND PROCESS TO CORRECT FAL; HAVE A FIBER OPTICAL LINK IN AN OPTICAL COMMUNICATION NETWORK" <D>. A transparent optical communication network that ensures the protection of the main communication channel of each supported wavelength and supports occasional traffic on a separate channel. In the event of a disruption or degradation on the main channel, these communications are redirected to the occasional channel.
