METODO E DISPOSITIVO PER LA SOPRAVVIVENZA DEL TRAFFICO IN SISTEMI DWDM CON ADD/DROP NEL CASO DI INTERRUZIONE DEL COLLEGAMENTO A FIBRE OTTICH |
摘要 |
A traffic survival method in optical fiber telecommunication systems and in particular DWDM and having amplification sites (10) with ADD/DROP of channels and arranged between fiber spans is described and claimed. In accordance with the method the ASE noise produced in amplifiers (13) in the site is amplified in power to compensate at output the power of channels (n) lost by breakage of the site inpul span. An amplification device with ADD/DROP and a telecommunication system with it is also described and claimed. |
