Claims

[Scope of utility model registration request]

(1) A plurality of multi-port side optical fiber cables with one end tied together, a light guide section that emits light received from the input side end face from the output side end face, and one single port side optical fiber cable. are formed separately and connected by a connecting member so that the end face of the binding part of the multi-port side optical fiber cable is brought into close contact with the input side end face of the light guiding part, and the connecting side end face of the single-port side optical fiber cable is connected to the end face of the bundle part of the multi-port side optical fiber cable to the input side end face of the light guiding part. The optical coupler is brought into close contact with the output side end face of the optical part, and the light transmission area of the input side end face of the light guide part covers the entire core part of the bundle part end face of the multi-port side optical fiber cable. The optical fiber cable has a size such that the light transmission area of the output side end face of the light guide part has a size such that the entire area is covered by the core part of the connection side end face of the single port side optical fiber cable. Characteristic optical coupler.

(2) The optical coupler according to claim 1 of the utility model registration claim, 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. .
