Abstract

Se divulga un sistema de comunicaciones opticas y un método para poner en marcha y detener el funcionamiento de un sistema a fin de garantizar la seguridaddurante la reparacion de la ruptura de una fibra. Una técnica para deterner el funcionamiento de un sistema optico de comunicaciones con intervalos de fibrasde transmision optica intercaladas en serie entre los sitios de transformacion optica y una pluralidad de sitios de amplificador incluye detener elfuncionamiento de los dos amplificadoresen cualquiera de los lados en los que hay una disrupcion de la fibra y de ambos amplificadores en los mismos sitiosdel amplificador que proporcionan la transmision en la direccion opuesta, seguido por la desactivacion de todos los amplificadores dentro de una misma líneaoptica entre los sitios de transformacion optica. Durante la puesta en marcha, los amplificadores entran en un modo de operacion con el objeto de ignorar unsistema de interrupcion del servicio del sistema, se fuerza a que opere un amplificador en un sitio terminal y, posteriormente, comienzan a operar lossucesivos amplificadores en un nivel de potencia intermedia segura antes de alcanzar la plena portencia operativa.An optical communications system and a method for starting and stopping the operation of a system to ensure safety during the repair of a fiber breakage are disclosed. A technique for determining the operation of an optical communications system with intervals of optical transmission fibers interspersed in series between the optical transformation sites and a plurality of amplifier sites includes stopping the operation of the two amplifiers on either side on which there is a disruption of the fiber and both amplifiers at the same amplifier sites that provide transmission in the opposite direction, followed by the deactivation of all amplifiers within the same optical line between the optical transformation sites. During start-up, the amplifiers enter into an operating mode in order to ignore a system service interruption system, an amplifier is forced to operate at a terminal site and subsequently begin to operate the subsequent amplifiers at a level safe intermediate power before reaching full operational power.
