How much do you know about Optical fiber cable?

A dielectric waveguide that transmits light waves. Optical fiber cable is a kind of fiber composed of two layers of transparent media in concentric circles. The most widely used dielectric material is quartz glass (SiO2). The inner medium, called the core, has a higher refractive index than the outer medium, called the cladding.

The refractive index of the core or cladding is adjusted by doping the silica glass with impurities such as germanium, phosphorus, fluorine, boron, etc. The transmission wavelength of optical fiber cable for communication is mainly near-infrared light with a wavelength of 0.8 to 1.7 microns. The core diameter of an Optical fiber cable varies by type, usually a few microns to 100 microns, and most of the outer diameters are about 125 microns. It has a plastic coating on the outside. Optical fiber cables are made by combining single or multiple Optical fiber cables with reinforcement and protection. Optical fiber cables can be used in a variety of environments. Optical fiber cables are manufactured in a similar way to cables.

Optical fiber cable communication is one of the important ways of modern information transmission. It has the advantages of large capacity, long relay distance, good confidentiality, no electromagnetic interference and copper saving.
