Fiber Splice Tube Fiber Optical Heat Shrink Tube

Fiber Splice Tubes, also known as Optic Fiber Heat Shrink Tube, Fiber Optic Fusion Protection Tube or Fiber Optic Splice Protection Tube, is a critical component of modern optical fiber communication networks. It is a specialized type of tubing designed to protect and secure optical fibers by providing a durable and reliable protective layer that can withstand the harsh environments commonly encountered in telecommunications installations.

These protection sleeves are specifically designed to support and safeguard fiber optic fusion splices. Their rigidity enables them to provide some level of protection to the splice area. Additionally, the ease of installation minimizes the risk of damage to the splice. The splice sleeves are heat shrinkable, and after correct alignment of the fusion splicing, heat is applied, causing the sleeve to shrink and provide environmental protection to the splice.

Expertly designed to precise specifications, the optic fiber heat shrink tube is made from high-quality materials that ensure it meets strict industry standards for performance and durability. Its unique properties enable it to withstand extreme temperatures, humidity, and mechanical stress, making it ideal for use in a wide range of industrial, commercial, and residential applications.

As an important component in fiber optic networks, heat shrink tubing ensures that optical fibers remain secure and protected from environmental factors that could otherwise interfere with their performance. This critical function helps to maintain the high levels of data transfer speeds, reliability, and efficiency that are essential to the functioning of modern communication networks.

Optic fiber heat shrink tube is an essential component of any robust and reliable fiber optic communication system. With its proven performance, durability, and reliability, it is an essential tool for ensuring that today’s communication networks operate at peak efficiency, enabling businesses, organizations, and individuals to communicate more effectively and efficiently than ever before.

Optic Fiber Heat Shrink Tube is a component that is made up of cross-linked polyolefin and hot melt tube, as well as a steel rod. This is used to protect the fiber optic splicing components. The inner thermal fusion tube is made up of a high-quality polymer that is soft, transparent, and has fast shrinkage. This means that it will not produce bubbles due to uneven heating. The cross-linked polyolefin is temperature resistant and has high strength and elongation properties. The middle metal steel pin is made of 304 stainless steel, and the ends are polished to be round. The steel rod keeps the fusion tube flat and prevents it from warping due to high temperature heating, which could cause damage to the internal fiber.

The Fiber Optic Fusion Protection Tube is commonly used in fiber optic splice boxes, fiber optic terminal boxes, fiber optic distribution boxes, fiber optic joint boxes, and other communication fiber optic equipment. It not only protects the splice point but also increases the mechanical strength of the fiber. This reduces the risk of damage to the fiber during the installation process. Additionally, the tube does not affect the optical fiber conductivity characteristics. If a transparent fiber optic fusion protection tube is used during the butt fiber optic splicing process, the fusion of the fiber can be easily seen.

To use the Fiber Optic Fusion Protection Tube in a fusion splicing machine, the outer skin of the fiber optic cable must first be peeled. The fiber optic cable is then fixed, paying attention to the core bundle tube. The optical fiber is then peeled and passed through the Fiber Optic Fusion Protection Tube, making sure to separate the different colored fibers. The power of the fiber optic fusion splicing machine is then turned on, and the appropriate fiber optic fusion mode is selected. The prepared fiber optic endface is cut according to the fiber, and the windshield is opened to remove the fiber from the fiber optic fusion splicer. The Fiber Optic Heat Shrink Tube is then moved to the location of the fiber fusion splice point, put into the heater, and heated up. After heating, the fiber is removed from the heater, and the spliced fiber is put into the fiber optic splicing tray. The fiber is fixed to the tray, splice box, terminal box, etc. Finally, the operation is complete.

how to use Fiber Optical Heat Shrink Tube

Features

  • Excellent heat resistance: Optic fiber heat shrink tubes are designed to withstand high temperatures and are highly resistant to heat and flames.
  • Durability: These tubes are made from high-quality materials that provide excellent protection for optic fiber cables.
  • Moisture resistance: Optic fiber heat shrink tubes are highly resistant to moisture and can protect cables from water and other liquids.
  • Easy to use: Optic fiber heat shrink tubes are easy to install and require no special tools or equipment.

Function

  • Cable Protection: Optic fiber heat shrink tubes are used to protect cables from environmental factors, including moisture and heat. These tubes provide an additional layer of protection to the optic fiber cable, which can help to extend the lifespan of the cable and maintain its performance. The tubes are also resistant to UV rays, which can cause cable jackets to become brittle and crack over time.
  • Splicing and Termination: Optic fiber heat shrink tubes are commonly used in splicing and termination applications. When two optic fiber cables are spliced together, a heat shrink tube is used to protect the splice point from external factors that can cause signal loss or damage. The same is true for termination points, where the tube is used to protect the exposed ends of the optic fiber cable.
  • Insulation: Optic fiber heat shrink tubes provide excellent insulation for optic fiber cables. They are used to protect the cables from external heat sources that can cause signal loss or damage. The tubes are also used to prevent water penetration, which can affect the performance of the cable.
  • Repair: Optic fiber heat shrink tubes are used to repair damaged optic fiber cables. When a cable is damaged, the heat shrink tube is used to cover the damaged area and protect the cable from further damage. The tube also helps to maintain the integrity of the cable and prevent signal loss.

Application

  • Fiber Optic Cables: Optic fiber heat shrink tubes are used in the production of fiber optic cables. The tubes are used to protect and insulate the fiber optic connectors and splices. The heat shrink tube is slid over the connector or splice, and then it is heated to shrink the tube tightly around the connector or splice. This creates a strong, protective seal that prevents moisture, dust, and other contaminants from entering the connector or splice.
  • Telecommunications: Optic fiber heat shrink tubes are used in telecommunications to protect and insulate fiber optic connectors and splices. They are used in applications such as local area networks (LANs), wide area networks (WANs), and fiber to the home (FTTH) installations. The tubes are also used to repair damaged fiber optic cables, allowing for a quick and easy fix to any broken cables.
  • Data Centers: Optic fiber heat shrink tubes are used in data centers to protect and insulate fiber optic connectors and splices. They are used to connect servers, storage devices, and other network equipment, ensuring a high-speed, reliable data transmission. The tubes are also used in data center upgrades, allowing for easy installation of new fiber optic cables and connectors.
