Fiber Optic Splice Protector, Heat Shrink Sleeve

Fiber optic splice protector, also known as heat shrink sleeve or fusion splice protector, is an essential component used in fiber optic splicing to protect and strengthen the splice points between two optical fibers. When two fiber optic cables are spliced together, the exposed bare fibers are joined and then enclosed within a splice sleeve.

How They Work:

  1. Enclosure of Spliced Fibers: After the fusion splicing or mechanical splicing process, the exposed area of the spliced fibers is inserted into the fiber optic splice protector.
  2. Protection from Environmental Factors: The fiber optic splice protector or sleeve provides protection to the delicate spliced fibers from environmental factors such as dust, moisture, and physical stress, ensuring the integrity of the splice over time.
  3. Heat Shrinking: Most splice sleeves are made of a heat-shrinkable material, typically made from polyolefin or similar materials. When heat is applied, the sleeve shrinks, tightly encapsulating the spliced fibers and providing mechanical protection.
  4. Ensuring Signal Transmission: The splice sleeve also helps to maintain the optical alignment of the spliced fibers, ensuring minimal loss of signal transmission.
  5. Color Coding: Some splice sleeves come in different colors, which can be used for identification purposes, especially when dealing with multiple splices within a single fiber optic cable.

Fiber optic splice sleeves are available in various sizes to accommodate different fiber diameters and splicing techniques. They are essential components in both outdoor and indoor fiber optic installations, providing reliable protection for spliced fibers in a wide range of environments.
