Hollow-core microstructure optical fiber preform, optical fiber and method for manufacturing thereof

Abstract

The present disclosure provides a hollow-core microstructure optical fiber preform, an optical fiber, and a method for manufacturing thereof. An objective of the present disclosure is to introduce a support sheet into a nested structure unit of the hollow-core microstructure optical fiber preform, which not only increases the number of reflection surfaces without increasing the number of nested layers of glass tubes, but also achieves a more accurate positioning by the support sheet and improves manufacturing accuracy as compared to a tangential structure of nested glass tubes, such that the following technical problems, difficulty in controlling a curvature of reflection surfaces, low manufacturing accuracy, large difference between actual loss and theoretical loss, or poor batch consistency, in related anti-resonance optical fibers, caused by increasing the number of layers of nested microstructure units in order to increase the number of reflection surfaces, are solved.

Dependencies are inferred from the claim text.
