Light travels down a fiber optic cable by bouncing off the walls of the cable repeatedly. Each light particle photon bounces down the pipe with continued internal mirror-like reflection. The light beam travels down the core of the cable.
The core is the middle of the cable and the glass structure. The cladding is another layer of glass wrapped around the core. Cladding is there to keep the light signals inside the core. There are many types of fiber optic cables, often that end up in fiber optic cable assemblies to execute their function.
Fiber optic cables carry light signals in modes. A mode is a path that the light beam follows when traveling down the fiber. There are single mode and multimode fiber cables. Single mode fiber is the simplest structure. It contains a very thin core, and all signals travel straight down the middle without bouncing off the edges.
Single mode fiber optic cables are typically used for CATV, Internet, and telephone applications, where the signals are carried by single mode fibers wrapped into a bundle.
In areas such as industrial facilities where large motors, controllers, and air conditioners are constantly starting and stopping, fiber optic cabling is highly recommended. Speed: Fiber-optic cabling is many times faster than traditional copper cabling. The small diameter glass fibers can support bandwidth speeds in-excess of gigabit speeds per strand.
While copper cabling can support these speeds, it would take multitudes of large diameter category 6 cables aggregated together to reach the speeds of one fiber strand. Distance: Fiber cable is the ideal means for long-distance, point-to-point hardline communications. The fiber wires have replaced the copper wire as transmission cable since it has more advantages than the electrical cables.
The reasons clearly explain that the fiber optic cables are far better than the coaxial copper cables and this is why Fiber optic cables are preferred over the conventions transmission mediums. Light or Laser light to be precise is used for the optical fiber communication because of the reason that the laser light is a single wavelength light source.
While the other light signals like sunlight or bulb light have many wavelengths of light and as a result, if used for communication they would produce a beam which is very less powerful and on the other hand, the laser having a single beam would result in a more powerful beam as output. In Optical fiber communication, light is used as a signal which transmitted inside the optical fiber cable. This mode of communication has characteristics which are important to be discussed and makes it a good mode of communication.

Optical communication is any type of communication in which light is used to carry the signal to the remote end, instead of electrical current. Optical communication relies on optical fibers to carry signals to their destinations.
Because of its numerous advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world. Since the development of low-loss optical fiber cables in the s, optical communications became one of the most popular methods of communication. Optical communication systems consist of the following components:.
