ABSTRACT:
The invention describes a method for optical communication of information between transmitter and receiver spatially separated from each other. The principle of heterodyne reception is utilized. A non-modulated optical carrier of a laser arranged on the receiving side is subdivided in a first fiber-optical coupler KE into two portions, the transmission path EMF and the local laser wave LL. In one branch, a displacement of frequency by the amount of .DELTA.f takes place. The non-modulated optical carrier passes through a one-mode fiber EMF in direction transmitting side and is modulated there with an effective signal in a modulator MOD (FIG. 1). This now modulated optical signal travels back to the receiving side, where it is converted with the local laser wave LL into an intermediate frequency band.
