Filed: 1988-12-02
Abstract: PURPOSE:To improve on-site workability by using fibers which are aligned after the clad layers of the fiber butt parts are removed and a certain angle with transmission path fibers is provided. CONSTITUTION:Part of leak light is emitted from bus fibers 1, 2 when the clad layers 14 of bus fiber 1, 2 sections are removed. This leak light changes largely with the angles of the bus fibers 1, 2.

The tap fibers 3, 4 are disposed symmetrically with the butt parts, by which the transmission and reception of the light are easily executed through the aperture of the core 15. Namely, the light is branched and coupled by utilizing the end faces of the fibers 1 to 4 and, therefore, the branching ratio of the light is variable and the constitution of the device having any light receiving sensitivity is possible.
