Fiber Optics
Fiber optic cables are a common factor in cable television industry. Internet and also some other communications mediums. They are considered strands of optically pure thin glass that carry digital information over long distances. Mostly used in communication mediums due to the availability of a higher bandwith, these fiber optics will carry the light far longer than many other forms of electrical signal carriers.
Because of the sudden improvements in fiber optics these higher end signal carriers have replaced the conventional core type electrical wires in many industries. How it works is fiber optics are long, thin strands of pure thin glass that are arranged in bundles referred to as optical cables that are used to transmit light signals over long distances. A single optical fiber consists of a core that is the thin glass center of the fiber where the light travels, cladding which is the outer optical material around the core that reflects the light back into the core and a buffer coating which is a plastic coating that protects the fibers from damage and moisture.
Due to its smooth transition, fiber optics are recommended for longer distant signal transmission. With minimum number of amplifiers these fiber optics calbles can carry the amount of data carried in many electrical wires. When fiber cables run alongside each other for long distances, they don’t experience crosstalk unlike some types of electrical transmission lines. Although fiber optics being higher in value, it will save some money in the longer run with less maintenance. Fiber optics is thinner which is why unlike electrical signals in copper wires; light signals from one fiber do not interfere with those of other fibers in the same cable which results in clearer reception. The loss of signal is also less in fiber optics than in electrical copper wires which is why lower-power transmitters can be used instead of the high-voltage electrical transmitters.
Since its suitability to be used in digital signals, optical fibers are mostly used in the telecommunication aspects. Medical imaging, mechanical imaging and plumbing use fiber optics in many of their digital cameras due to its flexibility.
