摘要： PROBLEM TO BE SOLVED: To provide an optical fiber unit that maintains oneness without coming loose in the terminal part and that excels in discriminability, and also to provide its manufacturing method and an optical fiber cable.
SOLUTION: A plurality of coated optical fibers 11 are bound by using a spirally formed plastic ribbon 20; therefore, while the optical fiber unit maintains oneness of the unit without coming loose in the terminal part, no coated optical fibers 11 are strongly tightened, preventing transmission characteristics from being deteriorated. In addition, the wide plastic ribbon 20 can be easily discriminated.
