Abstract

Изобретение содержит последовательно соединенные первый каскад фазового модулятора, первый фиксированный оптический элемент связи, второй каскад фазового модулятора и второй фиксированный оптический элемент связи. Радиочастотные модулирующие сигналы, которые подаются на каждый каскад фазового модулятора, регулируются по амплитуде для компенсации ошибок в значениях углов связи первого и второго оптических элементов связи. Уровни напряжений смещения постоянного тока, которые подаются на каждый каскад фазового модулятора, подстраиваются для компенсации асимметричной фазовой модуляции. Средства согласования импедансов, подключенные между выходными контактами радиочастотных модулирующих сигналов и фазовых модуляторов, согласовывают импеданс между ними.
