Claims
- 1. A method of manufacturing a plastic optical fiber including (1) a core made of a setting type transparent silicone rubber and (2) a cyindrical outer portion made of a high molecular weight substance whose refractive index is at least 0.02 less than that of the core, comprising the steps of:
- a) injecting the silicone rubber for the core into the cylindrical outer portion;
- b) setting the injected silicone rubber at room temperature; and
- c) heating the core and the outer portion at a temperature of 120.degree. C. or greater for at least one hour to stabilize the light receiving properties of the optical fiber.
- 2. A method according to claim 1, wherein the high molecular weight substance for the outer portion of the optical fiber contains at least one fluorine atom in each repeating unit of the polymer.
- 3. A method according to claim 1, wherein the injected silicone rubber is set by electron beam irradiation.
- 4. A method according to claim 1 wherein the silicone rubber is set at room temperature.
