Usually everyone will regard optical fiber as optical cable, which is very confusing, but they are actually not the same. When you walk on the street, you will find such a warning: Be careful of underground optical cables, do not dig! Instead of paying attention to optical fiber. This article will introduce the difference between optical fiber and optical cable.
In real life, many people confuse optical fiber and optical cable. In order to understand the difference between optical fiber and optical cable more intuitively, let's first look at a diagram of the structure of an optical cable. Moreover, it can be clearly seen from the structure diagram that optical fiber is the core part of the optical cable, so optical fiber is not an optical cable. Next, I will introduce optical fiber and optical cable to you respectively.
Currently commonly used optical fiber is made of glass, so optical fiber is very fragile. So, how is the fragile optical fiber used as a medium for light transmission to transmit information? The answer is that the outer layer of the optical fiber needs to be covered with a protective structure, such as a loose tube, waterproof grease, spinning wheel, PE outer sheath, etc., so that the covered optical fiber cable is called an optical cable, and data is transmitted over long distances through the optical cable. Therefore, the optical fiber is not the optical cable itself, it is the core part of the optical cable.
Summary: After being processed by multi-layer protective structures, optical fibers can not only be made into optical cables, but also fiber optic patch cords and fiber optic PLC splitters. These products play a key role in telecommunications, railway communications, radio and television networks, national defense communications, the Internet of Things, and other fields. The future of mankind is inseparable from the development of science and technology, and the development of science and technology is inseparable from communication transmission. I hope this article will be helpful to you.
