FIELD: radio engineering, communication.SUBSTANCE: invention relates to communication engineering and can be used in optical communication systems. The communication system comprises: nodes (102-102), configured to communicate with one or more devices; a central node (100); a passive optical network (106), having a multiplexer/demultiplexer (108), configured to demultiplex a first optical signal transmitted from the central node (100) to nodes (102-102), and multiplex second optical signals, obtained from one or more nodes (102-102), each assigned a wavelength on which it emits an optical signal; wherein for forward transmission of signals from one node (102-102) to at least one of the other nodes (102-102), said node (102-102) is configured to emit, at a wavelength assigned to said at least one other node (102-102), an optical signal comprising a signal to be transmitted; and the multiplexer/demultiplexer (108) of the passive optical network (106) is configured to combine the optical signal from said one node (102-102) with the first optical signal.EFFECT: high throughput of transmission channels.15 cl, 7 dwg |
