Fibre 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. fibre optics is very thin strands of glass or plastic fibre that carry light along its length and is
widely used in fibre optic communications because it allows communication over long distances at higher bandwidths
compared to other forms of communication.
Because of the sudden improvements in fibre optics these higher end signal carriers have replaced the conventional
core type electrical wires in many industries. How it works is fibre 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. Consisting of three layers, the inner core will carry the light from the sender to the receiver, while
the next level of layer reflects the light back on to the core to make sure none is lost and finally an outer layer
will protect the light signal from environment.
Due to its smooth transition, fibre optics are recommended for longer distant signal transmission. Some main
benefits of using fibre optics is its low loss, high data carrying capacity where a single high bandwidth fibre
cable replaces thousands of electrical links and long distances between amplifiers. When fibre cables run alongside
each other for long distances, they don't experience crosstalk unlike some types of electrical transmission
lines.
Several miles of optical cable could be cheaper than copper wire saving your provider and you money. fibre
optics is thinner which is why unlike electrical signals in copper wires; light signals from one fibre do not
interfere with those of other fibres in the same cable which results in clearer reception. The loss of signal is
also less in fibre optics than in electrical copper wires which is why lower-power transmitters can be used instead
of the high-voltage electrical transmitters.
Fibre optics is most often suited for carrying digital information which is why most industries such as
telecommunications and computer networks are frequent users of it. Due to the flexibility of fibre optics usages
today it is often seen in almost any industry.
