An optical element for incorporation into optical transmission means and comprising an optical fiber provided with a coating with a substantially circular cross section applied essentially coaxially closely around the fiber, to which coating is imparted such an adhesion to the optical fiber that a contraction tendency in the coating brought about in connection with the application of the coating affects the fiber with such an axial compressive force in its whole length that the force causes a real shortening of the fiber and a corresponding increase of the elongation at break of the fiber. The fiber can be provided with an intermediate protective layer, and an intermediate adhesive layer can be used. Optical transmission means comprising one or more optical elements in a sheath are described.
An optical element for incorporation into optical transmission means which comprises an optical fiber provided with a coating with a substantially circular cross section applied essentially coaxially closely around the fiber, to which coating is imparted such an adhesion to the optical fiber that a contraction tendency in the coating brought about in connection with the application of the coating affects the fiber with such an axial compressive force in its whole length that the force causes a real shortening of the fiber and a corresponding increase of the elongation at break of the fiber, said shortening amounting to at least 0.5% of the original length of the fiber when otherwise the element is not affected by external forces.
Optical transmission means comprising at least one optical element located in a sheath wherein said optical element consists of an optical fiber provided with a coating with a substantially circular cross section applied essentially coaxially closely around the fiber, to which coating is imparted such an adhesion to the optical fiber that a contraction tendency in the coating brought about in connection with the application of the coating affects the fiber with such an axial compressive force in its whole length that the force causes a real shortening of the fiber and a corresponding increase of the elongation at the break of the fiber, said shortening amounting to at least 0.5% of the original length of the fiber when otherwise the element is not affected by external forces.
