IPC: G02B6/44
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To improve skew characteristics by coating two dummy fibers positioned on an outer side and one or more optical fibers parallelly arranged between them altogether. SOLUTION: Between the dummy fiber 1A of a core number 1 and the dummy fiber 16A of the core number 16 positioned on the outer side, the optical fibers 2,..., 15 of the core numbers 2-15 are arranged. Then, in the state of parallelly arranging 16 of them, they are coated with a batch coating layer 20 composed of ultraviolet ray curing resin or the like altogether in a tape shape to constitute the coated optical fiber tape. While a core is turned to an optical waveguide in the optical fibers 2-15, the dummy fibers 1A and 16A are not provided with the optical waveguide. By arranging the dummy fibers 1A and 16A on the outer side where slew become large in such a manner, optical signals are not transmitted to the dummy fibers 1A and 16A and the skew characteristics of the coated optical fiber tape are improved as a result.
