摘要： A single-mode optical fiber for use as a stub fiber in an optical fiber connector is disclosed. The optical fiber is configured minimize the adverse effects of multipath interference (MPI) that can arise in a short, single-mode conventional stub fiber that has a large group index difference. The optical fiber is also configured to have a mode-field diameter that is substantially the same as that of single-mode optical fibers intended for use as field fiber in a mechanical splice connector, along with a cutoff wavelength λ C ≤ 1200 nm. An optical fiber connector that uses the optical fiber as a stub fiber is also disclosed.

摘要： A distributed refractive index optical fiber having a multilayer structure of concentric layers made of (co)polymers selected from the group consisting of homopolymers HP1, HP2, ..., and HPn manufactured from two or more kinds of monomers M1, M2, ..., and Mn and having refractive indexes gradually lowering in this order, and one or more kinds of binary copolymer CP of these monomers. Mixed layers of mixtures of the (co)polymers of the adjacent layers are formed between the adjacent layers. The central portion of the optical fiber has the highest refractive index, and the refractive indexes of the optical fiber decreasing gradually toward the outer circumferential portion thereof. This optical fiber can be manufactured continuously by supplying (co)polymers to a concentric multilayer nozzle, and drawing the (co)polymer therefrom. The polymers mutually diffused among the layers.

摘要： A novel process for producing an optical transmission medium comprising a drawing step of drawing a molten portion of a preform to form the optical transmission medium is disclosed. In the process, the preform is heated by irradiation with laser light thereby being partially molten, and desirably rotated in a fixed direction, during the drawing step. An apparatus comprising a means for heating and melting partially a preform by irradiation with laser light and a means for drawing a molten portion of the preform is also disclosed. A novel plastic optical transmission medium is formed of a plastic wherein molecules are oriented in a certain direction not in parallel to the longitudinal direction of said medium is also disclosed.
