Optical Fibre

In today’s connected world, effective transmission of data is very important. Fibres have been the medium of data communication. Earlier it was metallic wires and in the recent times it is optical fibre. Read More..

What is an optical fibre and how does it help transmit data?

An optical fibre is the medium that sends light signals down fibres. These light signals are able to carry tremendous amount of data without much loss to quality. The technology concerned with application of optical fibre is called fibre optics. The optical fibre are hair thin strands of fibre made of pure glass or plastic. The light is passed through the centre of the fibre, which is called the core. Cladding, which is an outer encasement to the core helps keep the light trapped in the core, using a technique called total internal reflection.

Advantages of fibre optic:

Optical fibres have mostly replaced copper wire communication in the UK. The advantages of optical fibre:

  • Very high bandwidth. This means volume of data transmitted is very high.
  • Longer distance signal transmission with negligible loss.
  • Negligent electromagnetic interference.

Let us understand a bit more about optical fibre:

What are types of optical fibre?

Optical fibre isprimarily of two types– Single mode and multimode fibre. Here’s an over view of single mode vs multimode fibre:

Single mode fibre has

  • a smaller core, about 8-9 microns, and carries the light signal straight down the fibre.
  • Lower loss and distortion, unlimited bandwidth and applied for long distance transmission of data. It is used for telecommunication network, internet, CATV, remote offices, undersea.
  • Is lesser in cost than multimode fibre.
  • Types of single mode fibre cable are: Standard single mode fibre (G.652), Cutoff shifted fibre (G.654), Low water peak fibre (G.652), Dispersion shifted fibre (G.653), Non-zero dispersion shifted fibre (G.655), Bend insensitive fibre (G.657)

The multimode fibre has

  • a five to six times larger core (approximately 50-60 microns) and the light signals follow various paths travelling within the core
  • It is mainly for short distance transmission of data. Used mostly for LED sources, slower local area networks and connecting computer networks.
  • More expensive than single mode fibre
  • Types of multimode fibre cable are om1 fibre, om2 fibre, om3 fibre, om4 fibre, om5 fibre.

How does optical fibre work?

When data has to be transmitted through a fibre, it starts as electrical energy, converts into photons or light rays, travelling in waves through inner core of the fibre. The core of the optical fibrecarry the light rays to transmit data through principle of total internal reflection. The photons (light particles) bob up and down the fibre core. An outer layer, called the cladding keeps the light in the core secure, without letting it escape. When the light particles reach the other-end an optical receiver decodes and converts it back to electrical energy, which then the receiving device is able to read and display as data for the user.

Wireless communications and cloud computing are gaining importance, however, presently the majority of data in voice and video signals are still transmitted through optical fibrenetwork. According to various reports,

  • Fibre optic broadband is already available to 96% of UK properties, although many users are still considering switching.
  • By end of 2020, additional 3.2 million homes and businesses in hard to reach, remote parts of UK are ready to be connected with gigabit ready full fibre broadband.

Optical fibre networks are the networks built to connect people and devices across cities, counties and even several nations. These networks are complex installations of wired networks with appliances to transmit large amounts of data over hundreds and thousands of kilometres. Optical fibre networks are typically laid by telecommunication companies worldwide; however, as the data demand grows significantly, more and more governments and other tech organisations.

Optical fibre is used to carry information between two destinations using optical or light-based technology. Be it data transfer requirements within four walls of an enterprise or accessing data from servers that reside in different continents, optical fibre is some of the most common means of data transmission across long distances.Itis used to transmit light between the two ends of the fibre and are widely used in fibre optic communications. Their popularity as long-distance data carriers of choice is owed to the higher bandwidths and data transfer rates.

There are three key types of optical fibre: single mode fibre, multimode graded-index or multimode fibre, and multimode step-index fibre. The difference between the three lies in how light travels down the fibre, which in turn depends both on the wavelength of the light and the mechanical geometry of the fibre.

In a single mode fibre, a light beam travels straight through the fibre with no reflections from the core-cladding sidewalls at all. Because of this, only the fundamental zero-order mode is transmitted. This also eliminates modal dispersion, which is often the cause for pulse overlap. It has a tiny core of 5-10 microns in diameter, which means that the signals are able to travel without interference. This kind of fibre is used for internet and telephone connectivity. On the other hand, multimode fibres have much bigger core diameters, resulting in higher-order modes being propagated. Multimode fibres are often used to transmit information over short distances, which is why it is used for linking computer networks together.

While fibre optics are safer than copper wires in the sense that they don’t carry any electricity, however it is recommended that fibre optics is handled with care, especially for people involved in the installation.

Most advanced technologies in communication such as 4G and 5G heavily rely on a superior network of fibre optics. Technology such as 5G need fibre optic network to offer ultra low latency, higher speeds and denser coverage. Since 5G is still in its infancy and5G applications are yet to mature, optical fibre continues to be a promising medium required for 5G. A lot of 5Gspeed and low-latency promises are still in the theoretical stage and only time will tell if they’ll be able to surpass the speed and simplicity offered by optical fibre.

We are all used to WiFi connections everywhere, which may make you wonder if optical fibre is any better than all ubiquitous WiFi connections. The short answer is yes. Optical fibre usually offers much faster speeds when compared with wireless transmission in the form of WiFi communication. However, WiFi networks also tend to slow down when multiple users are connected to the same network and can lead to congestion. Fibre optic network, on the other hand, can continue offering a consistent experience despite handling multiple users. Moreover, when it comes to connecting at a distance, WiFi suffers from range constraints and you start to lose the connection as you move further. For fibre optics, you’ll have to lay physical lines in order to connect at a distance.
