Abstract
1. A transmission system for the multiple bidirectional use of an optical fibre (1; 71) in wave-length multiplex, comprising a plurality of light sources in at least two different wavelength ranges, and a number of broadband light receivers (E1-8; E71-75) which corresponds to the number of light sources, each of said light sources and light receivers being connected to the bidirectionally used optical fibre via wavelength-dependent coupling devices and demultiplexers respectively, characterized in that the light sources (S1-S4; S5-S8; S71-S74) of a given wavelength range are each time connected together, via a non-selective, wavelength-independent coupling device (6; 7; 76) constructed as an optical fibre branch, to a first optical fibre (2; 3; 72) which is each time connected, via the window-selective, wavelength-dependent coupling device (10; 11; 80), to the second bidirectionally usable optical fibre (1; 71), to the other end of which there is connected a further window-selective, wavelength-dependent coupling device (11; 10; 81) which is adapted to the other coupling device, a wavelength-dependent demultiplexer (9; 8; 79) being connected to the output of said demultiplexer which are associated with the individual light source wavelengths there being connected the associated receivers (E1-E4; E5-E8. E71-E75).
