Optical fiber heat shrinkable tube

Short Description:

Fiber Optic Fusion Splice Protection Sleeves is Consist of cross linked polyolefin, Hot fusion tubing and Stainless Reinforcing Steel Rod which keep optic transmission properties of optical fiber and enhance the protection to optical fiber splices. Easily operating to the optical fiber during installation without damaging and clear sleeve make it easy to detect splice before shrinkage. Sealing structure make the splice free from influence of temperature and humidity in special environment.

Fiber optic heat shrink splice sleeve,40mm, 45mm, 60 mm. Transparent plastic tube and stainless steel rod designed to prevent stress and protect fusion fiber optic splices in field and factory operations.

Product Benefits

Transparent plastic tube

Stainless steel rod

Prevents stress and protects fusion fiber optic splices in field and factory operations

Sleeves are made of ethylene vinyl acetate (EVA)

Sleeves have heat-activated memory which causes them to shrink under heat

Sleeves shrink tightly to exclude air and hold the rod firmly, preventing abrasion of delicate glass fibers

Product Features

1. Consist of cross-linked polyolefin, hot fusion tubing and stainless reinforved steel rod (quartz or ceramic).
2. Keep optical transmission performance of optical fiber.
3. Provide safe protection to optical fiber splicing.
4. Easily use and avoid any damage to the optical fiber during installation.
5. Sealing structure provides good performance to the splicing in the environment with temperature and humidity.

Product Applications

It is composed of heat shrinkable polyolefin, hot melt adhesive and a rod to strengthen the joint.  The fiber coating is reconstructed to provide mechanical strength in the fusion joint area and maintain optical transmission.
