Fibre Cables – Let’s have a look at the Characteristics, Types, and Uses

Fibre Optic Cable has become the backbone of today’s networking system.

They span almost everywhere, connecting local phone systems, and transmit data across long distances.

These cables have steadily replaced copper wires because of their ability to send signals faster and most securely.


So what do we need to know about the characteristics, types, and uses of fibre optics?


Fibre Cables – Characteristics

  • Optic cables are coated with plastic, which helps protect them from exposure to cold, heat, and other weather conditions.
  • This plastic coating also protects them from the sun’s ultraviolet rays and electromagnetic interface.
  • These cables are very reliable and transfer data fast.
  • Signals transferred through fibres carry higher strength and need less maintenance.
  • Optic cables have huge data capacity and are capable of establishing a connection and transferring data faster across continents.


Fibre Cables – Types

The most commonly used fibre cables include single-mode, multimode, and photonic fibres.



Single-mode fibre cable has a very small diameter core that allows propagation of only one mode of light.

Due to this reason, as the light passes from the core, the number of light reflections created decreases.

It lowers the attenuation, and the ability of the light signal to travel to a longer distance increases.

These types of cables are typically used in higher bandwidth and long-distance applications by colleges, universities, CATV and telecom companies.



Multimode Optical Fibre Cables cables have a larger core diameter that allows the light to propagate in multiple modes. Because of the multiple modes of light propagating in the core, the number of reflections of lights increases. This, in turn, facilitates the fibre optic cable to carry more data in a given time.

Due to the high dispersion of light and high attenuation rate, the quality of the signal transferred reduces over distance.

Because of this these types of fibre optic cables are typically used in short-distance data applications like LANs.

Photonic Fibres

In photonic fibres, the core can be formed in an air cavity or glass.

This is a new type of fibre optic cable available in the market with its performance still under observation for several applications.




Fibre Cables – Uses

Fibre optic cables offer several benefits in many different fields, out of which a few ones are discussed below:



Over the years, telecommunication companies have turned to fibre optic cable.

Whether you are at home or in the office and you have made a phone call or browsed the web in the last few days, there is probably a fibre cable at work.



Fibre optic cables are also useful in the medical field.

Flexible fibre strands can be inserted in certain body areas, such as blood vessels and lungs.

Fibre optic cables allow doctors to get a glimpse of a body’s internal organs without the need for exploratory surgery.


Government Projects

Fibre optics are also used by many government agencies as they find great use in different areas.

These cables play an essential role in the operation of submarines, sonar, certain aircraft, and many defense vehicles.



In short, fibre optic cables have significantly evolved the communication and data transfer abilities of different systems.

By allowing faster and more accurate transfer rates its range of benefits and features have made it a preferred communication channel.

Telecommunication companies, medical and government agencies have already made the switch to Fibre Optic Cable.
