A method of manufacturing a flat type optical cable, said method comprising the steps of: passing a number of parallelly extending optical fibers over a surface of a first roller, said first roller having an axis and having a layer of light-curable lacquer on the surface thereof, said fibers being provided with a layer of lacquer on one side thereof after passing over the first roller; passing the parallelly extending fibers over a second roller having an axis arranged perpendicular to the axis of the first roller, the fibers being rotated 90° by passing over the second roller; and exposing the flat assembly of rotated fibers to light to cure the lacquer to bond the fibers together with lacquer present only on facing circumferential parts of the optical fibers.
