Ke

Hong Enterprises Ke

Hong Enterprises, based in Guangdong, China, specializes in optic fiber heat shrink tubes. Their products feature crosslinked clear heat shrinkable tubing with a clear fusion liner, stainless steel reinforcement, and PE material rated for 600V. They provide solutions for low-voltage applications, with smooth, deburred ends to reduce fiber damage and extended liner lengths to prevent contact with the fiber backbone.

Branch-off clips and customizable options are available for complex splicing needs. 2. Bonelinks Bonelinks offers fiber splice tubes or fusion protection tubes made from cross-linked polyolefin and hot fusion materials reinforced with stainless steel rods.

These tubes provide mechanical strength, moisture resistance, and clear sleeves for easy splice detection. They support both single fiber and ribbon fiber configurations and allow for customized designs to meet specific installation requirements. 3.

TE Connectivity T

E Connectivity provides a wide range of heat shrink tubing suitable for fiber optic applications.

Their RAYCHE

M heat sleeves offer electrical insulation, mechanical protection, environmental sealing, and strain relief. Available in single-wall and dual-wall designs, these tubes are compatible with back-end connector sealing, breakouts, and cable transitions. Clear types allow inspection of covered components, and the tubing comes in various materials, colors, and sizes.

Sommer Gmb

H Sommer Gmb

H manufactures heat shrink tubing with options for cut pieces, longitudinal slits, and punch-outs. They offer tubing with or without adhesive coating in multiple designs and sizes, suitable for high-volume production and specialized fiber optic applications. Considerations When Choosing a ManufacturerMaterial and Reinforcement: Look for cross-linked polyolefin with stainless steel or other reinforced rods for durability.

Voltage and Environmental Ratings: Ensure the tubing meets the required voltage rating and environmental resistance (moisture, temperature). Customization: Some manufacturers provide color coding, branch-off clips, and custom sizes for complex splicing. Ease of Installation: Smooth ends, extended liners, and heat-activated memory features reduce fiber damage during installation.
