Claims (1)

В пассивной оптической системе дальней связи, в которой множество децентральных устройств соответственно через собственную световодную соединительную линию соединены с оптическим разветвителем, который непосредственно или по меньшей мере через еще один дополнительный оптический разветвитель через световодную шину соединен с общим световодным вводом центрального устройства, причем децентральные устройства и центральное устройство передают или соответственно принимают оптические цифровые сигналы по способу передачи одновременного двустороннего разговора на одинаковой полосе частот. Для избежания соответствующего изменению конфигурации двоичного кода своего сигнала передачи отрицательного воздействия на чувствительность при приеме центрального устройства приемо-передающая схема выполнена таким образом, что выход оптоэлектрического преобразователя соединен с входом электрооптического преобразователя через электрический инвертор приемного сигнала, а между выходом электрооптического преобразователя и световодной соединительной линией введена оптическая линия задержки, время задержки которой согласовано со временем срабатывания электрического инвертора приемного сигнала.In a passive long-distance optical system, in which a plurality of decentralized devices, respectively, are connected via an own fiber optic connecting line to an optical splitter, which is directly or at least through another additional optical splitter connected to a common optical fiber guide of the central device, and decentralized devices and central device transmit or respectively receive optical digital signals by transmitting simultaneously two-way conversation in the same frequency band. In order to avoid a transmission signal corresponding to a change in the binary code configuration, a negative effect on sensitivity when receiving a central device, the receiving-transmitting circuit is designed in such a way that the output of the optoelectric converter is connected to the input of the electro-optical converter through the electric inverter of the receiving signal, and between the output of the electro-optical converter and the fiber optic connecting line An optical delay line has been introduced, the delay time of which is coordinated with response time of the electric inverter receiving signal.
