Claims

[Scope of utility model registration request]

(1) Separate one single-port side optical fiber cable, a light guide section that emits light received from the input side end face from the output side end face, and multiple multi-port side optical fiber cables with one end tied together. the single-port side optical fiber cable is formed in a body and connected by a connecting member to bring the single-port side optical fiber cable into close contact with the input side end face of the light guide part, and the bundle part end face of the multi-port side optical fiber cable is brought into close contact with the output side end face. In the optical branching device, the light transmission area of the input side end face of the light guide part has a size that covers the entire core portion of the connection side end face of the single port side optical fiber cable, and the light transmission area of the input side end face of the light guide part An optical branching device characterized in that the light transmission area of the side end face has a size such that the entire area is covered by the core portion of the bundle end face of the multi-port side optical fiber cable.

(2) The light splitter according to claim 1 of the utility model registration, characterized in that the light guiding portion is formed by forming a cladding on the outer periphery of a core that transmits light to reflect the light coming from the core side. .
