Embodiment Construction

[0007] Next, the core, cladding, light shielding cladding, and protective cladding constituting the POF cable of the present invention will be described in order.

[0008] POF cable of the present invention such as figure 1 As shown, there is a plastic optical fiber (POF) 1, a protective cladding layer 2 arranged on its outer periphery, and a light shielding cladding layer 3 arranged on its outer periphery, wherein the plastic optical fiber (POF) 1 includes a core and a protective cladding layer formed on its outer periphery. At least one layer of cladding (core / cladding structure). The material (core material) constituting the core of the POF cable of the present invention is not particularly limited, but as the POF cable, from the viewpoint of satisfying long-term heat resistance at around 100 to 105°C, polymethyl methacrylate is preferably used. Copolymers of ester (PMMA) or methyl methacrylate (MMA) units and one or more vinyl monomer units (hereinafter, these are referre...

Abstract

The invention relates to a heat-resistant cable. A sheath structure comprises a fluoroolefins-contained copolymer and polyamide resin which both have extremely-high adhesion and can mechanically protect the cable and restrict loosening possibility under a high-temperature environment. Moreover, the copolymer has high oxygen shielding property and can restrict transmission loss increase caused by the oxidative degradation of POF (Plastic Optical Fiber) under the high-temperature environment.

Description

technical field [0001] The present invention relates to a plastic optical fiber cable, in particular to a plastic optical fiber cable with excellent long-term heat resistance in a high temperature environment. Background technique [0002] Conventionally, as an optical fiber, a silica-based optical fiber capable of excellent light propagation over a wide wavelength range has been put into practical use mainly as a trunk system, but the silica-based optical fiber is expensive and has low processability. Therefore, plastic optical fiber (hereinafter, abbreviated as POF), which is cheaper, lighter, larger in diameter, and has advantages such as end surface processing and easy handling, has been widely used in the field of lighting applications, sensor applications, or indoor wiring applications such as FA, OA, and LAN. Practical. [0003] However, due to the characteristics of POF itself, the transmission loss increases in a high-temperature environment, so it cannot fully mee...
