How Do Fiber Optics Cables Actually Work in Practice?



Did you know that according to predictions, the global fiber optic cabling market will reach $22 billion in revenue by 2027?

There’s a good reason for this fiber optic cable growth. We use technology to transmit information all over the world. From the way global businesses run to how we use our internet, fiber optics has a hand in it.

Yet, even with knowing how much of an effect fiber optics can have on global marketplaces, the question of “how do fiber optic cables work?” remains. And the answer is a little tricky to parse out.

Keep reading for the breakdown of how fiber optic cables make instant communication possible.

What Is Fiber Optic Cable?

Fiber optics lighting cable is made up of incredibly thin glass or plastic strands that are capable of carrying data via pulses of light.

In order to transmit data, the initial receiver converts the electrical signal into pulses of light. The light then travels through the strands of glass or plastic.

On the other end, a receiver converts the pulses of light back into an electrical signal. Below we will discuss further how a fiber optic cable works.

Encode Data Into Light

Some of the best fiber wires are able to transmit data at extremely high speed and over long distances due to the way in which data is encoded into the light. Light is a very fast-moving electromagnetic wave and can travel through the cable without losing any data.

The data is encoded into the light by turning the light on and off at different speeds. The light is then amplified and sent through the cable.

Send Light Using Fiber Optics

The light travels on a small, thin tube of glass or plastic. The light is then bounced off the walls of the tube and sent to the other end.

Light travels using the tube for very long distances. This allows the light to travel without dropping the signal.

Light Is Read by a Receiver

This light is then read by a receiver such as photoelectric cells, which converts the light into electrical signals. These signals can then be used to carry information.

You can use the light signal in a variety of applications. These include the telecommunications industry, computer networking, and data transmission.

Convert Light Back to Original Data

Fiber optic cables convert light back into the original data. We call this process data conversion.

To convert data correctly, the fiber optic cable must be shielded to encode the data properly.

Know These Fiber Optic Cables Ideas

Fiber optic cables are an essential part of the modern world, carrying data at the speed of light. Data is encoded into light, then it travels using fiber optics. At the end of the fiber optic, the light is read by a receiver, which converts the light into the original data.

Therefore, it is essential that you know how fiber optic cable works. So, go out there and choose the best fiber optics when you consider buying cables.
