ABSTRACT:
In a method of preventing twisting of a fusion-spliced optical fiber in the process of encasing the optical fiber in a casing, one of a pair of optical fibers is wound N turns in one direction to form a first coil. Another of the pair of optical fibers is wound N turns in another direction opposite to the direction to form a second coil. Ends of remainder portions of the optical fibers which are not wound are fusion-spliced to each other to form a fusion-spliced portion. The fusion-spliced portion is fixed within a casing. The remainder portions of the optical fibers are pushed into the casing to expand the first and second coils.
