A multi-waveguide cylindrical optical conductor for telecommunications cable, the conductor comprising a plurality of optical fibers, each of which is a unit cylindrical fiber constituted by a core and by cladding, the unit fibers are all connected together by silica after a fiber-drawing operation, wherein said core of said unit cylindrical fiber has a diameter of about 8 .mu.m to 10 .mu.m, wherein said cladding has an outside diameter lying in the range 25 .mu.m to 35 .mu.m, and wherein all of the cores of said unit fibers are either situated regularly on generator lines of a cylinder having the same axis as said conductor, or else are parallel with one another and are coplanar. An optical conductor can thus be obtained having an outside diameter of 125 .mu.m and containing six waveguides each having a diameter of about 25 .mu.m to 35 .mu.m.
A method of manufacturing a multi-waveguide optical conductor, the conductor comprising a plurality of optical fibers, each of which is a unit cylindrical fiber constituted by a core and by a cladding the unit fibers being all connected by silica after a fiber drawing operation, wherein:
