1. A method of transmitting an optical data signal via a fiber optical medium in opposite directions at the same carrier wavelength, comprising:
providing a fiber-optical line comprising passive optical elements and is terminated with transparent bidirectional signal dividers for input/output of data signals to and/or from the fiber-optical line, wherein preliminarily or during implementation of the method, an overall reflected signal power reaching the input of an optical receiver is measured or calculated for a specific optical communication system, wherein a value is compared with a maximum noise power acceptable for a data signal extraction by the optical receiver, and then, by excluding and/or redistributing highly reflecting elements in a path of an optical signal between a transmitter and the optical receiver, or by replacing the passive optical elements for lower reflecting ones, wherein an overall power of a reflected signal reaching the input of the optical receiver is lowered to a level that is acceptable for separating a target optical signal from an overall optical signal reaching the input of the optical receiver and, as a result, the transmission of the optical signal is achieved in the opposite directions at the same carrier wavelength for the specific optical communication system. |
