HOLDING STRUCTURE FOR OPTICAL FIBER

摘要

PROBLEM TO BE SOLVED: To handle a long-sized optical fiber in one body without causing the fiber to become disorder as a whole and to hold even an optical coupler compactly and stably in one body at the same time. SOLUTION: The long-sized optical fiber 1 is arranged shifting in circumference position in plane and another optical fiber 14 is coupled with this optical fiber 1 to constitute the optical coupler; and the optical fiber coupler 4 is held and stored integrally in a sheet material 12 for fixation such as an adhesive and a film together with the optical fibers 1 and 14.
