Title:
PLASTIC OPTICAL FIBER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/054141
Kind Code:
A1
Abstract:
This plastic optical fiber 10 comprises a core 11 including a first fluorine-containing resin as the principal component, and a cladding 12 disposed on the outer periphery of the core 11 and having a second fluorine-containing resin as the principal component. When a fiber structure 13 comprising the core 11 and the cladding 12 is heated at 90°C for 24 hours, the shrinkage factor in the length direction of the fiber structure 13 is 5% or lower. The shrinkage factor is calculated on the basis of numerical formula (I): shrinkage factor (%) = [(D1 – D2)/D1] × 100, where D1 is the length of the fiber structure 13 before being heated at 90°C for 24 hours, and D2 is the length of the fiber structure 13 after being heated at 90°C for 24 hours.
