Title:
METHOD FOR MANUFACTURING OPTICAL FIBER BUNDLE FERRULE, AND MULTI-CHANNEL OPTICAL FIBER RECORDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/066029
Kind Code:
A1
Abstract:
A method for manufacturing an optical fiber bundle ferrule (14), the method comprising: manufacturing an optical fiber positioning mold, and forming a plurality of positioning holes in the optical fiber positioning mold (S100); respectively inserting first ends of a plurality of optical fibers (4) into the positioning holes of the optical fiber positioning mold (S200); fixing the parts of the plurality of optical fibers (4) exposed outside and close to the optical fiber positioning mold with the optical fiber positioning mold by using a curing material, so as to keep the relative positions of the ends of the plurality of optical fibers (4) inserted into the optical fiber positioning mold unchanged (S300); inserting second ends of the plurality of optical fibers (4) into a tubular member (2), such that the optical fibers (4) located between the tubular member (2) and the optical fiber positioning mold form an umbrella-shaped portion (S400); fixing the umbrella-shaped portion and part of the tubular member (2) by using the curing material to form a fixed portion (3) (S500); and withdrawing the optical fibers (4) inserted into the optical fiber positioning mold from the optical fiber positioning mold (S600). Further provided is a multi-channel optical fiber recording system based on the optical fiber bundle ferrule (14).
