Development of a Simulator for Testing Methods of Forming Analogue Signals in the Form of a Sequence of Command Codes in an Optical Communication Channel

The article deals with a simulator designed to test the possibility of transmitting telemetry command codes in the form of sequences of video pulses through a long-distance fibreoptic communication line. The general scheme of a long-distance analogue FOCL, the simulator’s scheme, the principles of its functioning and its element base are considered. An electrical filter is implemented in the simulator, which allows to eliminate some distortions of transmitted pulses. Oscillograms of signals before and after filtering are shown. The conditions related to the dynamic range under which the developed FOCS is able to function are experimentally established.
