Abstract
There is provided a plastic optical fiber capable of exhibiting good light transmitting characteristics even at high temperatures, which comprises a core layer, a cladding layer, and a protective layer as basic consititutional units, wherein the protective layer has a heat distortion temperature [HDT] of at least 120.degree. C., a thickness of at least 10 .mu.m, and a cross-sectional area of at least 0.07 times the sum of cross-sectional areas of the core and cladding layers. There is also provided such a plastic optical fiber good in high-temperature light transmitting characteristics, which comprises a core layer, a cladding layer, and a protective layer as basic constitutional units and has a plastic coating layer having a silane-crosslinked structure provided as an outer layer thereof, wherein the protective layer has a heat distortion temperature [HDT] of at least 120.degree. C., a thickness of at least 10 .mu.m, and a cross-sectional area of at least 0.07 times the sum of cross-sectional areas of the core and cladding layers.
