ABSTRACT:
The invention provides a plastic optical fiber cable comprising a plastic optical fiber having a core/clad structure, a light blocking coating layer provided around the plastic optical fiber, and a protective coating layer provided between the outermost layer of the core/clad structure and the light blocking coating layer. The outermost layer of the core/clad structure is made of a fluorine-containing olefin polymer containing at least a tetrafluoroethylene unit, the crystal melting heat of the fluorine-containing olefin polymer being 59 mJ/mg or lower. The light blocking coating layer is made of a resin primarily containing a polyamide resin, the content of polyamide resin-derived monomers and oligomers being 1.5% by weight or lower.
