FIELD: electric communications via fiber-optic lines, possible use for ultra compression of large groups of short and long distance lines by wave lengths. ^ SUBSTANCE: packing device is made with spiral optical route on one or several repeatedly used prisms. Optical automatic telephone station is made of multi-line devices, multiple optical switches and connectors, interconnected by multipoint inter-cascade screens with optical commutation of channels of compressed lines. ^ EFFECT: decreased amount of equipment and increased speed of operation. ^ 2 cl, 10 dwg, 15 tbl |
