Abstract
This invention relates to a plastic optical fiber having a three-layer structure comprising a core, a cladding and a protective layer wherein the core material is polymethyl methacrylate and the cladding material is a copolymer composed of 20 to 45% by weight of long-chain fluoroalkyl methacrylate units represented by the following formula (1), 54 to 79% by weight of methyl methacrylate units, and 0.05 to 2% by weight of methacrylic acid units. This invention also relates to a plastic optical fiber cable having a four-layer structure wherein the optical fiber cable is produced by covering the aforesaid optical fiber with a jacket layer.
