FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication engineering and can be used in optical communication systems. The communication system comprises: nodes (1021-102n), 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 (1021-102n), and multiplex second optical signals, obtained from one or more nodes (1021-102n), each assigned a wavelength on which it emits an optical signal; wherein for forward transmission of signals from one node (1021-102n) to at least one of the other nodes (1021-102n), said node (1021-102n) is configured to emit, at a wavelength assigned to said at least one other node (1021-102n), 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 (1021-102n) with the first optical signal.
EFFECT: high throughput of transmission channels.
