В статье приведены результаты решения проблемы затухания оптического сигнала
в волоконно-оптических линиях связи. Описаны широко используемые современные
технические решения промежуточных усилительно-регенерационных узлов волоконно-оптических линий связи. Показаны достоинствами и недостатки существующих
промежуточных волоконно-оптических усилителей. К достоинствам оптоэлектронных
регенераторов сигнала относится полное восстановление исходных характеристик
оптического сигнала. Оптоэлектронный регенератор позволяет ограничить величину
внутренних и внешних оптических шумов допустимыми величинами, но усложняет и
удорожает построение ВОЛС. Оптические усилители сигнала также используются для
увеличения дальности действия волоконно-оптических линий связи. Главным
достоинством промежуточных волоконно-оптических усилителей является их
относительно простая конструкция и, следовательно, невысокая стоимость, а также
большая величина коэффициента потерь и выходной мощности. Техническая задача
разрабатываемого волоконно-оптического усилителя - создание усилителя, в котором
происходит передача сигнала и энергии, по существу, аналогичное распределение в
волокне, которое также сконцентрировано в той области волокна, в которой
присутствует флуоресцентная присадка. Представлены характеристики,
функциональная и структурная схемы оптического ретранслятора с эрбиевыми
усилителями.Приведены конструктивные особенности построения и принцип работы
эрбиевого усилителя.
