Title:
NET-SHAPED OPTICAL FIBER RIBBON AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/016387
Kind Code:
A1
Abstract:
A net-shaped optical fiber ribbon, comprising a semi-regular structure and a completely irregular structure, wherein the semi-regular structure is formed by combining a plurality of single regular optical fibers, and comprises long bonding points and short bonding points; the long bonding points and the short bonding points are alternately combined to form a net-shaped structure; the completely irregular structure is formed by means of a foaming technique; glue supply pressure fluctuates during bubble breakage to form the completely irregular structure; and all bonding points, which are connected by means of the optical fiber ribbon, in the completely irregular structure have different sizes and distances. A piezoelectric-valve-based gluing mode is used by the semi-regular structure, such that relatively low costs can be ensured; lower attenuation of the optical fiber ribbon is realized by using a long-short combination mode; additional attenuation of the optical fiber ribbon is reduced by means of spaced dotting on front and reverse sides; the completely irregular structure is formed by using the foaming technique, such that the additional attenuation is further reduced; and one-step forming is implemented, and an existing ribbon formation process is used, such that investment costs are low.
