Abstract

The invention discloses a forming method of a flexible optical fiber ribbon, which comprises the following steps: 1) a plurality of optical fiber units advancing in parallel are respectively coated with coloring layers capable of mutually distinguishing colors through a coloring mold, and then the coloring layers on the optical fiber units are incompletely cured in a curing oven; (2) an upper glue outlet unit and a lower glue outlet unit of the glue dispensing equipment respectively drop a bonding material B into a gap between the optical fiber units from the upper side and the lower side of the optical fiber units; and (3) the bonding material A, the bonding material B and the coloring layer are gradually cured, the adjacent optical fiber units are connected together through a first bonding part and a second bonding part which are formed through curing, any two adjacent optical fiber units are not bonded any more through curing of the coloring layer, and therefore the positions without the first bonding part and the second bonding part can be separated. The flexible optical fiber ribbon has good bending performance in the downward direction and the upward direction, attenuation of side fibers of the flexible optical fiber ribbon is small when the side fibers are stressed, and improvement of the optical fiber density of the optical cable is facilitated.

Description

technical field

[0001] The invention belongs to the field of optical fiber, and more specifically relates to a flexible optical fiber ribbon, a molding method thereof and a glue dispensing device for implementing the molding method. Background technique

[0002] With the advent of the 5G era, data has grown explosively, and massive amounts of data need to be realized in the form of dense networking. In the context of intensive and dense networking in data centers and computer rooms, the demand for large-core, ultra-high-density optical cables has emerged as the times require. Traditional large-core optical cables include rigid optical fiber ribbon cables (such as skeleton optical cables and layer-stranded ribbon cables) and layer-stranded optical cables in the form of loose fibers. Rigid optical fiber ribbon cable has the characteristic that the whole ribbon can be welded, and the welding construction efficiency is high. However, the traditional optical fiber ribbon cable ...
