摘要： Disclosed are: a plastic optical fiber comprising a core and a clad composed of at least one layer, wherein the clad comprises a copolymer comprising, as a copolymer components, 10 to 35% by weight of ethylene, 45 to 69% by weight of tetrafluoroethylene, 20 to 45% by weight of hexafluoropropylene, and 0.01 to 10% by weight of a specific fluorovinyl compound; and a plastic optical fiber code comprising the plastic optical fiber. The plastic optical fiber and the plastic optical fiber code have such a level of heat resistance that they can withstand the use at an actual use temperature of 105°C. The plastic optical fiber and the plastic optical fiber code have a good balance among wet heat resistance, bending loss, flexibility and other properties and also has excellent pistoning properties, and therefore are suitable for automotive interior wiring and house wiring.
