Abstract

Patente de Invenção: <B>"REDE ANELAR WDM"<D>. Esta rede anelar é subdividida em uma primeira e uma segunda parte, sendo que partindo de um elemento central de rede são alimentados sinais de trabalho às primeira e segunda partes da rede anelar. Sinais de proteção são transmitidos na direção dos sinais de trabalho aos elementos de rede da outra parte do anel até os elementos de rede que encerram as partes do anel. Os sinais de proteção são transmitidos então na direção oposta aos sinais de trabalho na parte correspondente do anel até o elemento central de rede.
