A structure of bare fiber hot-melt unit

Abstract

The invention discloses a bare fiber heat fusion unit structure, relates to the field of bare fiber heat fusion and solves the problem that the existing bare fiber is likely to be damaged by a thermoplastic sleeve during butt fusion. The bare fiber heat fusion unit structure comprises a bare fiber, a bare fiber protection sleeve and a thermoplastic sleeve. The bare fiber is a 0.125mm standard bare fiber formed by stripping a rubber-covered wire, and the end of the bare fiber is connected onto a heat fusion joint. A notch is arranged on the bare fiber protection sleeve in the sleeve length direction, the bare fiber is embedded into the sleeve through the notch, and a plurality of round through holes are formed in the sleeve wall. One end of the thermoplastic sleeve is sleeved on the outer surface of the rubber-covered wire, the other end of the thermoplastic sleeve is communicated to the heat fusion joint, and the middle section of the thermoplastic sleeve wraps on the outer surface of the bare fiber protection sleeve. According to the bare fiber heat fusion unit structure, the layer of protection sleeve is sleeved on the outer surface of the butt fusion bare fiber, hot meting of the thermoplastic sleeve is not affected and the bare fiber is protected form damage. The bare fiber receives double powerful protection of the thermoplastic sleeve and the protection sleeve, and the fusion point is subjected to secondary protection. The length controllability of the bare fiber protection sleeve is good so that the bare fiber heat fusion unit structure can adapt to various optical cables and optical fibers with different packaging forms.

Description

technical field [0001] The invention relates to the field of bare fiber hot-melt, in particular to a structure of a bare fiber hot-melt unit. Background technique [0002] With the continuous and rapid development of the Internet, new online services emerge in an endless stream, especially online games, conference TV, video on demand and other services that have become popular in recent years, making people's demand for network access bandwidth continue to increase. [0003] Compared with other wired and wireless access technologies, optical fiber access has unparalleled advantages in terms of bandwidth capacity and distance. [0004] In the FTTH project, the user's indoor wiring is the most complicated link. As a substitute for the traditional indoor optical cable, the leather optical cable, combined with the on-site hot-melt quick connector, can provide users with broadband, voice and video services conveniently and quickly. On-site hot-melt quick connectors are currently...

AI Technical Summary

Problems solved by technology

When the thermoplastic sleeve is heated, it will slowly shrink and solidify. If it touches the bare fiber during shrinkage, it will burn the bare fiber, damage the bare fiber and cause it to be opaque, and cause the on-site fusion to fail.
