Splice Sleeves

The fiber-optic shrink tube, also known as the heat-shrink fiber protective sleeve, consists of three parts: the heat shrink tube, the hot melt tube and the stainless-steel needle or ceramic. Fiber-optic heat shrink tube is specially designed by cross-linked polyolefins, heat shrink tube and reinforced stainless-steel wire fiber continuity protection elements, it can improve the mechanical strength of fiber fusion points, protect the fusion point, to ensure the reliability of the fusion. Before shrinking, the transparent outer layer can be used to detect the correct connection at the light joint, allowing the fiber to be assembled easily and safely, and providing protection, maintaining the transmission characteristics of the fiber after shrinkage, providing strength and protection at the light joint.

Standard Splice Sleeves

The fiber is spliced together by the fiber-optic fusion machine, and then the fiber-optic successive sleeve is needed. The protection of fiber continuity points is very important. Single-core fiber-optic shrink tubes are made up of heat shrink tubes, hot melt tubes and stainless-steel needles (or ceramic rods/quartz rods). The bright outer layer makes it easy to detect the accuracy of the connection of the fiber optic connector, which allows the fiber to be stopped on a simple and safe day, and the optical transmission characteristics of the fiber are maintained after expansion, as well as the strength and protection of the processed fiber connector. Simple operation, regardless of whether the machine can be relied upon, can prevent the equipment outside the history of optical fiber damage.

Splice Sleeves Types

Huihongfiber ribbon fiber fusion protection sleeves is designed to accommodate 2-12 strip fiber. Stock length is 40 mm but can also be in the new 30 mm length for smaller packaging requirements. This product consists of an internal EVA meltable hose, polyolefin heat shrinks outer tube and single-strength or double-strength components. Our single-strength component sleeves have become the industry standard, with a shrinkage diameter of 4.9 x 4.4 mm, with special glass components. Our dual-strength component casings are designed to “clamp” the band, eliminating any excessive stress on the fibers and shrinking to a diameter of 5.7 x 4.9mm. This option can be used in a variety of glass and special high temperature plastic component combinations. The tubes are transparent so that the fiber can be seen during and after stitching.

Splice Sleeves from Professional China Manufacturer

Fiber-optic shrink tubes are successive components for enhanced protection or support positioning at the fiber optic continuity site. When we connect the fiber through a fiber-optic melting machine, we peel off the outer coating and protective layer of the fiber, which makes the fusion point vulnerable to external influences and reduces the mechanical strength accordingly. Therefore, the docking and continuation site needs to be strengthened protection.

In the maintenance and construction of fiber optic cables, we are most commonly used is the shrink sleeve. The heat shrink sleeve is a polyethylene shrink tube with hot melt on the inner wall and a small steel pipe with a diameter of about 1.5 mm in the middle. After heating, the polyethylene sleeve shrinks and encases the fiber optic connector and the small steel pipe together. This operation not only increases the strength of the fiber optic connector, but also avoids the effect of polyethylene casing shrinkage on the bending and deformation of the fiber optic connector. You can also make the connector have better moisture-proof performance. When heating should be aware: should ensure that the tube of air is all removed, even heating, to avoid the formation of bubbles when heat.

At the same time, the heating temperature should be reasonably controlled to avoid burning the polyethylene tube. Technicians according to different use environment, designed a different succession casing, such as a single fiber continuing casing, multiple fiber-optic succession casing.

Professional Splice Sleeves Manufacturer

Because of its high-quality performance, fiber-optic shrink tube plays an important role in the network trunk line, and how to use fiber-optic heat shrink tube is especially important for the user. The continuity of optical fiber is directly related to the quality and life of the project, the key lies in the preparation of the fiber end surface. if the fiber end surface is not qualified, the fuse machine refused to work, or the joint out of the loss is very large, does not meet the engineering requirements. After the fiber is melted, it is necessary to protect the fiber as well.


For years we use a big amount fiber optic splice sleeves from Huihongfiber, they work perfectly and save us a lot of cost, their products quality is always reliable but price always competitive, we trust Huihongfiber as long time partners, highly recommend them for the fiber optic communication products.
