Fiber Optics
Fiber optic cables are a common factor in cable television industry. Internet and also some other communications mediums. Fiber optics will carry digital information over long distances through a strand of optical thin glass. Fiber optics is very thin strands of glass or plastic fiber that carry light along its length and is widely used in fiber optics communications because it allows communication over long distances at higher bandwidths compared to other forms of communication.
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. Lower power transmitters can be used instead of high voltage electrical transmitters due to less power loss in fiber optics.
Since its suitability to be used in digital signals, optical fiber are mostly used in the telecommunication aspects. Due to the flexibility of fiber optics usages today it is often seen in almost any industry.
