Abstract: PROBLEM TO BE SOLVED: To obtain a novel optical energy transmission medium improved in mode coupling. SOLUTION: The optical energy transmission medium 10, such as an optical fiber, contains the plural particles formed in >=1 layer of coating layer enclosing a clad region and/or >=1 layer of buffer region layer 16 enclosing the coating layer. As a result, advantageous mode coupling is accelerated and consequently, the band-width potential lowered in dispersion is improved. This process for producing the optical energy transmission medium 10 consists in forming >=1 layer of the coating region layer and/or >=1 layer of the buffer region layer containing the particles in such a manner that the particles like those of fumed silica are maintained in the optical energy transmission medium and that the perturbation controlled along the optical fiber to enhance the mode coupling up to the extent of improving the band weight of the optical fiber is formed.

Abstract: PROBLEM TO BE SOLVED: To obtain a novel optical energy transmission medium improved in mode coupling. SOLUTION: The optical energy transmission medium 10, such as an optical fiber, contains the foam 26 formed in this medium 10 in such a manner that the microbending of the medium 10 is induced, the advantageous mode coupling is thereby accelerated and consequently dispersion is lessened and the band-width potential is improved. The foam 26 is formed in >=1 layer of buffer region layer 22 and/or at the boundary between a coating region 16 and the buffer region 22. The process for producing the optical energy transmission medium consists controllably in forming >=1 layer of the buffer region layer around a coated optical fiber in such a form that a desired amount of the foam 26 is formed and held in >=1 layer of the buffer region layer 22 and/or the boundary between the coating region 16 and the buffer region 22. The foam 26 generates the prescribed perturbation to enhance the mode coupling to the extent that the band-width of the optical fiber is improved. The size and amount of the foam 26 are controlled by the moisture content in the coating layer.

Abstract: PROBLEM TO BE SOLVED: To greatly increase the speed of the production line of coated optical fiber. SOLUTION: The speed of production line of coated optical fiber can be greatly increased by adopting the divided lamp system for curing the coated optical fiber 21. The glass fiber is coated with a protecting coat layer, partially cured by exposure to the first electromagnetic radiation line source, then the partially cured layer is cooled and the coated layer is exposed to the second electromagnetic radiation line source. The curing station 30 is divided into plural steps and the cooling steps 35 are provided between individual curing stations. Thus, the partially cured optical fiber is cooled and the line-drawing speed of the optical fiber can be increased thereby largely increase the line speed of the coated optical fiber production as a result.
