Abstract: PROBLEM TO BE SOLVED: To provide a coating material which ensures little residue on the glass of glass fibers after peeling from an array of the glass fibers while maintaining satisfactory adhesion to the fibers so as not to cause delamination by specifying the equilibrium elastic modulus and tensile strength of a primary coating. SOLUTION: An optical fiber 10 coated with a primary coating material 14 comprising a photosetting polymer material has a slender glass fiber 12 capable of propagating light waves in the longitudinal direction. The primary coating has 120-500 psi equilibrium elastic modulus at 20 deg.C and

Abstract: PROBLEM TO BE SOLVED: To provide an improved shape memory material for an optical fiber connector application. SOLUTION: A connector for joining an optical element, especially an optical fiber is disclosed. The connector is a sleeve made of a simple shaped memory polymer(SSMP) into which the optical fiber is inserted, and the sleeve is heated to collapse the sleeve around the optical fiber. The SSMP material is not crosslinked and can be manufactured by a variety of techniques including extrusion. Various methods for forming the bore of the connector and expanding the size of the bore from the memory state to the metastable state are disclosed.

Abstract: PROBLEM TO BE SOLVED: To provide an optical terminal device small in reflection, inexpensive and difficult to deform with the pressure. SOLUTION: An optical terminal device 100 is brought into contact with an optical fiber at end parts. The end part of the optical fiber is held in a cylindrical ferrule. The optical terminal device 100 reduces the reflection generated at a part where the optical path is suddenly changed in the refraction index (for example, a part where the optical fiber is brought into contact with the air gap). The optical terminal device 100 is provided with an approximately columnar part 110 which is projected from a back bone part 120 and held by the back bone part 120. The columnar part 110 and the back bone part 120 are cast of polymethyl-methacrylate (PMMA) as an integrated structure. Reflection of approximately -40dB can be realized with PMMA. The plastic material of the refractive index n=1.46±0.06 produces the reflection below approximately -34dB, which is allowable for many applications. In addition, the plastic material which is higher in the glass transition temperature Tg from approximately 80 deg.C is minimum in recess creep under the compressive load at high temperature.

Abstract: In accordance with the invention, an optical fiber is provided with a protective coating having enhanced thermal characteristics for easy removal from the optical fiber. In particular, at elevated temperatures used in stripping, the delamination resistance drops to low levels substantially independent of modulus. This permits fabrication of a protectively coated fiber which has relatively high modulus and delamination resistance at room temperature but, due to its enhanced thermal characteristics, is nonetheless relatively easy to strip at elevated temperatures. Thus, for example, applicants can provide a protectively coated optical fiber or ribbon with a room temperature modulus of at least 90 psi, and a high temperature delamination resistance that is less than 40% of the room-temperature delamination resistance and preferably less than 30%. Coatings based on a polyether backbone and non-polar monomers are preferred.
