Introduction In the current digital age, network components play a vital role in people's daily lives. Among them, fiber optics and cables have become the "black technology" in network transmission due to their unique advantages and characteristics. This article will provide a detailed analysis of the principles, characteristics, and applications of fiber optics and cables to help readers better understand the charm of these two major network components. II. Basic Principles of Fiber Optics and Cables Fiber optics, also known as optical fibers, are media that use the principle of total internal reflection to transmit optical signals. It is composed of a core, cladding, and protective sheath. A cable is a transmission system consisting of one or more fibers combined with a protective outer covering. The main working principle of fiber optics and cables is to achieve fast and long-distance information transmission through the transmission of light. III. Characteristics of Fiber Optics and Cables 1. Fast transmission speed: Fiber optics and cables use light as a transmission medium, which has a very high transmission speed. 2. Long transmission distance: Compared to traditional electrical signal transmission methods, fiber optics and cables can transmit information over longer distances. 3. Strong anti-interference ability: The optical signals transmitted by fiber optics are not easily affected by electromagnetic interference, ensuring the stability of information transmission. 4. Large bandwidth capacity: The bandwidth capacity of fiber optics is far greater than that of traditional cables, meeting the transmission needs of large amounts of data. IV. Applications of Fiber Optics and Cables 1. Communication field: Fiber optics and cables are the main transmission media for modern communication networks, widely used in telephone, Internet, television, and radio fields. 2. Data centers: In data centers, fiber optics and cables are used to connect servers, storage devices, and network equipment to ensure fast data transmission. 3. Industrial automation: Fiber optics and cables are used in industrial automation for monitoring, control, and data acquisition. 4. Medical field: Fiber optics and cables are used in medical equipment connections and data transmission, such as endoscopes and medical imaging.
