Inner Dia 3.8MM Fiber Heat Sleeve Protector Fiber Optic OEM

FTTH Drop Cable Joint Protect I.D 3.8MM Big Hole Fiber Heat Shrink Sleeves

Description: 

  Fiber Heat Shrink Sleeve is a special polyolefin thermal-shrinkable sleeve, also called EVA. The outer layer is made of high quality soft cross linked polyolefin material and inner hot-melt adhesive. The outer tube made with the characteristics of insulation, corrosion prevention and wear resistance, while the inner inner has the advantages of low melting point, waterproof seal and high adhesion.

The Fiber Heat Shrink Sleeve intends to protect (mechanically) fiber optic drop cable connection. The Fiber Heat Shrink Sleeve is built from shrinkable plastic tube with metal cylinder inside. The cables are inserted before splicing into the plastic tube. After making the splice, the shrinkable tube is heated and shrunk on the splice. It can protect the spliced fiber from being break down and unwanted bending and is coated with the plastic tube. It gives to the installer flexibility while using the spliced fibers during installation.

Features:

1. Not affect the optical conductivity of the spliced fiber

2. Easy operation, reduce the damage of optical fiber duringl installation

3. Strong practicality

4. Transparent casing

5. Quickly shrink, improving work efficiency

6. extend the service life of the fiber

7. No air bubbles, no fiber breakage
