PURPOSE:To obtain the titled fiber having a heat-resistance until near the glass transition point of a thermoplastic resin, and having a less tendency for suffering a mechanical injury by coating an org. optical fiber with a UV curable type resin, and by coating the obtd. optical fiber with a specific resin. CONSTITUTION:The titled cable is constituted of a core component 1 of the org. optical fiber, a shell component 2 of the org. optical fiber, the 1st coating resin layer 3 composed of the UV curable resin, and the 2nd coating resin layer 4. The characteristic of the titled cable lies in providing the 1st coating resin layer 3 composed of the UV curable resin, and the 2nd coating resin layer 4 composed of the resin having a larger glass transition point or a Vicat softening point than that of the core component polymer constituting the org. optical fiber, in order, as the resin layer coated on the org. optical fiber. Thus, the cable having the heat-resistance until the glass transition point of the core component 1 and having a sufficient resisting property against the mechanical injuring and a lateral pressure is obtd. The titled cable having an improved handling and practical properties is obtd. |
