- 1 - Abstract: The invention relates to a plastic optical fiber having good heat resistance. The fiber comprises a core made of a polymer comprising units of methyl methacrylate and a clad- ding made of a polymer containing at least 20 % by weight of fluorine. The core polymer is first washed with an or- ganic solvent in which the core polymer is substantially insoluble, and then the core is formed from the washed core polymer and the cladding is formed around the core. The step of washing the core improves the heat resistance and light attenuation of the fiber.
