Communication optical cables are the cornerstone of modern communication networks. They are used for long-distance, high-speed data transmission. Their working principle is based on the total reflection of light, and transmits information through optical signals in optical fibers. Communication optical cables are composed of multiple parts, mainly including:
Optical fiber: The core of a communication cable, used to transmit optical signals. Optical fiber is usually made of high-purity glass or plastic, and has the characteristics of low loss and high bandwidth. Optical fiber is divided into single-mode fiber and multi-mode fiber. Single-mode fiber is suitable for long-distance transmission, and multi-mode fiber is suitable for short-distance and local area network applications.
Buffer layer: Wrapped outside the optical fiber, it provides physical protection to prevent the optical fiber from being damaged by bending and extrusion.
Armor layer: In some optical cables, in order to increase the mechanical strength and environmental resistance of the optical cable, materials such as metal wire, steel belt or Kevlar fiber are added outside the buffer layer as armor layer.
Sheath: The outermost protective material, usually made of polyvinyl chloride (PVC), polyethylene (PE) or other weather-resistant materials, provides additional physical and chemical protection against water, ultraviolet rays and corrosive substances.
Communication optical cables can be divided into many types according to different application scenarios:
Direct buried optical cable: Optical cable directly buried underground, with strong mechanical strength and waterproof performance.
Pipeline optical cable: used in pipelines or pre-buried pipelines, with a smaller diameter and weight, easy to thread.
Overhead optical cable: used on poles or towers, usually self-supporting optical cable (ADSS) or composite ground wire optical cable (OPGW).
Submarine optical cable: used for long-distance communications across oceans or lakes, with extremely high waterproof and pressure resistance.
Indoor optical cable: used inside buildings, usually with a smaller diameter and softer sheath for easy wiring.
The selection of communication optical cables should be based on comprehensive considerations such as transmission distance, data rate, environmental conditions and cost. Proper installation and maintenance of optical cables can ensure the stability and reliability of the communication network. (Source: Dongguan HX Fiber Technology Co., Ltd)
