Abstract
Abstract An optical element for use in optical transmission comprising one or more optical fibers provided with an essentially tight-fitting coating and a strength member provided with an essentially tight-fitting coating of the same material, each of said coatings having an essentially circular cross-section, wherein the coating or coatings on the optical fibers are firmly connected with the coating on the strength member by connection means of the same material, and whose thickness is substantially smaller than the diameter of the coatings and where further the fiber or fibers are given a curve or wave shaped course. The connection means can be a continuous or locally broken fin and the coating can be applied commonly or separately around the fibers. Optical transmission means comprising such optical elements are described.
