Popular Design for Ftth Acessories - Optical fiber heat shrinkable tube – GELD

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

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.

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.
