Title:
PLASTIC OPTICAL FIBER, PREPARATION METHOD THEREFOR AND PREPARATION DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/045972
Kind Code:
A1
Abstract:
A plastic optical fiber, a preparation method therefor and a preparation device thereof. The preparation method includes the following steps: coordinating the fluidity of a fluororesin raw material and the fluidity of a PMMA raw material, and jointly matching and extruding the fluororesin raw material and the PMMA raw material in a multi-core coextrusion die (310). Producing a plastic optical fiber by using a multi-core co-extrusion method can help solve the problems of fluidity mismatching and air setting of an optical fiber cladding layer fluororesin raw material, improve the stability of the quality of optical fiber production, and achieve effects such as a more cladding layer uniform thickness, better optical fiber toughness and reduced optical fiber attenuation.
