Optical fiber is a technology used to transmit data by sending short light pulses along a long fiber, which is typically made of glass or plastic. These cables are used mainly for digital audio connections between devices. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. Optical fibers are also resistant to. Optical cable: When the phone converts the acoustic signal into an electrical signal and then transmits it to the switch via the line, the switch transmits the electrical signal to the photoelectric conversion equipment (converts the electrical signal into an optical signal). It can have different manifestations according to different environments, such as the need for waterproofing, buffering. There are mainly three types of cables used in network connection: twisted pair cables, coaxial cables, and fiber optic cables. Among them, fiber optic cables have become more and more popular in recent years for their information carrying at a high speed and it may gradually replace copper wires. Fiber-optic cables are at the core of modern communication networks, enabling the transmission of data at high speeds and over long distances with minimal signal loss.
