What is the composition of communication plastic optical cable

Summary: Communication plastic optical cable is composed of Optical Fiber, protective layer, stranded layer and sheath. The optical signal is transmitted in the fiber core, and the transmission and reception of the signal are realized through the cooperative work of the characteristics of the fiber and the equipment. Due to its superior characteristics, plastic optical cable is widely used in telecommunications, Internet and data transmission and other fields, providing an important infrastructure for people's communication and information exchange.

Communication plastic cable is a communication cable used to transmit optical signals, which is composed of optical fiber and plastic protective layer. It has the characteristics of small diameter, lightweight and flexible, easy to peel and install, and is suitable for short-distance transmission and indoor wiring applications.

The main components of communication plastic optical cable include optical fiber, protective layer, stranded layer and sheath. The composition and working principle of each part are described in detail below.

1. Optical fiber: Optical fiber is the core part of plastic optical cable, used to transmit optical signals. An optical fiber consists of one or more fiber cores and an outer refracting layer. Fiber core is the transmission channel of optical signals, usually made of high-purity silica or plastic materials, with high light conductivity. The refraction layer is a layer of material surrounding the outside of the fiber core, which is used to protect the fiber core from the external environment.

2. Protective layer: The protective layer is an outer protective material of optical fiber, usually made of polymer materials, such as polyethylene, polyvinylidene fluoride and so on. The protective layer is used to physically protect optical fibers from damage caused by stretching, bending, or extrusion. In addition, the protective layer can also improve the heat resistance and chemical corrosion resistance of the cable and enhance the service life of the cable.

3. Stranded layer: The stranded layer is a layer structure used to fix The Optical Fiber and the protective layer, usually made of polyester, polypropylene and other materials. The role of the stranded layer is to keep the relative position of the optical fiber and the protective layer unchanged, preventing movement and relative displacement between them to ensure the normal transmission and use of the optical fiber.

4. Sheath: Sheath is the outer protective structure of plastic optical cable, usually made of polyvinyl chloride, polyethylene and other materials. The sheath is mainly used for the overall protection of the entire cable to prevent external physical damage and chemical corrosion. The sheath can also provide the mechanical strength and fire resistance of the cable, ensuring the safety and stability of the cable during use.
