How Does Fiber-Optic Internet Work? Everything you need to know

Fiber optic internet, sometimes known as “fiber internet” or simply “fiber,” transmits data as light signals over tiny cables constructed of glass or plastic fibers. In comparison to different other types of internet connections like DSL and cable internet networks, fiber internet can provide quicker, more dependable download and upload speeds.

Fiber-optics service is quickly gaining popularity due to the lightning-fast speed it provides, which has resulted in a number of providers like AT&T, Charter Spectrum, and Xfinity adopting this technology as the demand is only increasing every day.

In this article, we’ll talk all about the fiber internet you need to know!

What’s the best thing about Fiber internet?

A fiber-optic network is used by the majority of gigabit internet providers, however, not all fiber internet connections are created equal.

Fastest Internet type – Fiber optic internet is the best of the best options whenever it comes to the internet, with speeds up to ten times faster than DSL.

Symmetrical Speeds – Fiber internet services have the same transfer speeds, however, DSL and cable internet plans typically have substantially slower upload speeds.

Great Reliability – On a fiber network, you do not have to worry about interruptions or traffic congestion.


Highly expensive – Fiber broadband internet plans are often more expensive than cable or DSL internet connections.

Availability –  It needs to be understood that the Fiber internet is only available to around half of the population in the United States, but cable and DSL are available almost everywhere.

Start-up costs – Fiber optic networks are more expensive to build than other types of internet connections, resulting in higher upfront costs for both providers and customers.

Is Fiber Internet available in your area?

By now, you must have started to think if there is any fiber internet provider around you. Understand that Fiber is a relatively new technology, and most providers are currently attempting to expand their fiber networks.

However, there are different internet service providers offering internet connections.  In case, you are looking for fiber internet around your area, head over to sites like localcabledeals where you just need to put in your Zip-code to find all the providers around your area. Or, you may simply get in touch with the customer service of a provider and ask them about the availability.

Benefits of Fiber Internet

Fiber optic internet, as opposed to other internet types like cable and DSL, is ideal for a variety of applications, which also includes a list of countless intensive online tasks.

Streaming TV — Fiber’s fastest internet connection quality makes it excellent for streaming anything even in HD or 4K, with little to no buffering.

Downloading shows/movies/games — Most fiber internet providers provide gigabit speeds, which drastically reduce download times for huge files like movies or games. So, you can transfer your data or even download it within mere seconds.

Online gaming – Fiber optic internet allows data to travel at up to 70% the speed of light, resulting in exceptionally little lag, which is ideal for gamers.

Video conferencing – Compared to other internet types like cable and DSL internet, fiber internet has faster upload rates, which are required for video conferencing as well as uploading photos and videos to social media.

Working from home — Now because of the changing dynamics, people have started working from home and hence they require better internet connections.

Unfortunately, some internet providers are having problems keeping up with the demand. With fiber internet’s improved data capacity, you do not have to worry about any task you have to do, even the meetings go as smoothly as possible.

How does the Fiber Internet work?

Fiber internet means different things to different providers.

However, some of the most commonly available fiber internet options are mentioned:

FTTN — fiber to the node

The first is Fiber-to-the-node (FTTN) connection. It uses fiber optic cables to transport data to a hub near your area of residence or location. For the rest of the way, the DSL or coaxial wires are responsible for transmitting the data rest of the way.

FTTN – hybrid fiber-coaxial network

The second one is FTTN connections. It is also known as a “hybrid fiber-coaxial network” or HFC,  and it is a prevalent type of internet connection offered by cable companies. When it comes to uploading speeds, this type of connection isn’t as dependable or quick as a pure fiber connection.

FTTC stands for fiber to the curb.

The FTTC connections are responsible for transporting the fiber optic signals even further than FTTN connections while finishing directly outside your property.

Similarly, FTTN uses a DSL or coaxial cable to act as a bridge between the home and the street, FTTC uses a DSL or coaxial cable to bridge the gap between your home and the street, making your connection subject to signal interference.

FTTH stands for fiber to the home.

Fiber to the house (FTTH) connections actively use fiber optic cables to link your home to the internet. FTTH is also called “fiber to the premises,” and also provides the best bandwidth, reliability, and consistency.


The post above may have answered many of your questions by now. It must have made it easier to understand fiber internet and its operations based on the demand.

The entire popularity of the fiber internet exists because of the fast speed and the consistent download and upload rates. While fiber internet isn’t always the cheapest option, the speeds and stability it provides can be more valuable than other internet options.
