Optical fiber is a flexible and transparent fiber that is made by stretching glass (silica) or plastic to a diameter slightly thicker than a human hair. Optical fibers are often used as a means of transmitting light between two ends of the fiber and are widely used in fiber optic communications, where they allow transmission over longer distances and higher bandwidth (data transfer rates) than electricity. Fibers are used instead of metal wires because signals travel along them with less loss. In addition, fibers are immune to electromagnetic interference, a problem that metallic wires suffer from. Fibers are also used for lighting and imaging and are often wrapped in bundles to be used to transmit light into or out of confined spaces, as in the case of fiberscopes. Specially designed fibers are also used for various other applications, some of which are fiber optic sensors and fiber lasers.
Optical fibers usually consist of a core surrounded by a transparent cladding material with a lower refractive index. Light is retained in the core by the phenomenon of total internal reflection, which causes the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes are called multimode fibers. Those that support one mode are called single-mode fibers (SMF). Multimode fibers generally have a wider core diameter and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 1,000 meters (3,300 feet).
The ability to splice optical fibers with low loss is important in fiber optic communications. It is more complicated than splicing a power wire or cable and involves precise fiber separation, precise alignment of fiber cores, and mating of these aligned cores. For applications that require permanent bonding, fusion bonding is common. In this technique, an electric arc is used to melt the ends of the fibers together. Another common technique is mechanical splicing, where the fiber ends are brought into contact by mechanical force. Temporary or semi-permanent connections are made using specialized fiber optic connectors. The field of applied science and engineering that is related to the design and application of optical fibers is known as fiber optics. The term was coined by Indian-American physicist Narinder Singh Kapani, widely regarded as the father of fiber optics.
Comprehensive fiber optic solutions
Nowadays, due to the increase in users, the increase in the volume of data transfer, online games, watching TV channels, providing services such as telephone, Internet, IPTV, etc., on the copper cable bed, due to low bandwidth, high attenuation and short distance support, it is affordable. It is not cheap and as a result, the best solution is to use optical fiber technology.
