Claims

[Scope of utility model registration request]

In the optical splitter-0, which has a mixing light guide relay rod having an input optical fiber connected to one end and a plurality of output optical fibers connected to the other end, the light guide relay The rod has a structure in which a high refractive index body is provided at the center on the input end side to which the input optical fiber is connected, and a low refractive index body is provided concentrically around the outer periphery of the rod. On the output end side where the output optical fiber is connected, a low refractive index body is provided at the center, a high refractive index body is provided concentrically around the outer periphery, and a low refractive index body is further provided at the outer periphery. The low refractive index body at the center on the output end side tapers into a conical shape from the output end side toward the input end side, and its tip is located between the input end and the output end. In addition, the high refractive index body on the outer periphery of the low refractive index body at the center on the output end side and the low refractive index body on the outer periphery are respectively the high refractive index body at the center on the large end side. and an optical splitter that is continuously integrated with a low refractive index body on the outer periphery of the splitter.
