What effect can the fiber heat shrink tube play in fiber fusion?

Composition of optical fiber heat shrinkable tube: The heat shrinkable tube is composed of transparent heat shrinkable tube, hot melt tube and stainless steel needle (or ceramic rod/quartz rod).

The role of optical fiber heat shrinkable tube:

1. The transparent outer layer facilitates the detection of the correct connection of the fiber splices, enables the fiber to be assembled simply and safely, and maintains the optical transmission characteristics of the fiber after contraction, providing strength and protection to the fiber splice. It can avoid the damage of optical fiber during installation.

2. Protect the optical fiber after fusion splicing, and the reinforced parts inside make the contact more firm.

3. It plays the role of a sheath after the fusion of the optical fiber is completed, the purpose is to waterproof, dustproof, and anti-aging.
