What is fiber optic internet?

best phone solution
Posted on Oct 16, 2021


The fastest internet available


Fiber optic is faster than both DSL and Cable. Compared to traditional copper wiring, it can carry vast amounts of data far more efficiently and offers better speed and stability than wireless connections. Fiber optics use light instead of electricity to send information across long distances, making fiber optic networks faster than other types of internet.


What are the benefits of fiber optic internet?

Fiber optics offer significant advantages over traditional copper-wire networks. Fiber optic service is available to any home or business that wants it, without affecting their existing telephone or cable television services. Fiber Internet provides greater bandwidth than other technologies, which means subscribers can start enjoying faster speeds relatively quickly. With fiber-optic internet, the amount of bandwidth available is only limited by the service provider and the number of users on the network.

How can I get it?

The easiest way to get Fiber Optic internet in your community is to contact your local ISP (Internet Service Provider) regarding availability in your area. They will be able to tell you right away if a Fiber Optic network is available and connect you with a Fiber Internet provider in your area.

The ISP will typically include other internet options such as DSL or Cable internet if availability is an issue. In some locations where there is no fiber option available, Wireless broadband may be offered as an alternative.

In some areas, Fiber Optic is only available from the phone company that serves your area. In this case, it will be called an “FTTN” installation (Fiber-To-The-Node) since the fiber lines run to a point where copper wires carry the signal to your home.

Benefits of fiber optic internet?


  • Ultra high speed compared to copper broadband.
  • Distance is not a problem with optic fiber; it can run miles without slowing down, unlike DSL & Cable Internet.
  • Reliable Fiber Internet, no electromagnetic interference or signal degradation.
  • The security of data on optic fiber networks is very high due to the lack of electromagnetic interference.
  • Data on an optic fiber is transmitted in light pulses, which can not be intercepted without physical access to the line itself.
  • Fiber optic networks are more secure due to the lack of signal leakage from houses and buildings connected by fibers.


What benefits does fiber internet bring for businesses?

Fiber internet for business is fast and secure. Dedicated fiber-optic networks are reliable and durable, meaning that companies using fiber-based broadband get greater bandwidth than DSL or Cable providers. Fiber has redundant pathways which ensure service availability to all customers. More businesses can be supported on a single network with less congestion, making it easier to support online high-bandwidth applications such as VoIP.

Fiber lines also do not interfere with other electronics, and signal degradation is not a factor in fiber optic connections. Fiber internet typically comes with SLAs (Service Level Agreement), which provide the subscriber business with an uptime guarantee for network availability, connection speeds, and other parameters.

A final benefit of fiber is its security. Since data transmitted over fiber lines are not susceptible to interference and signal degradation, it’s much more secure than copper-wire networks.

What are the disadvantages of fiber optic internet?

  • Fiber optics for homes and businesses usually do not affect current services such as phone or cable tv and vice versa.
  • Fiber optic installation is still expensive in comparison to traditional copper-wire networks.
  • Availability of fiber optics for homes or businesses depends on location; availability may be limited in rural areas.
  • Not all providers of fiber internet offer unlimited plans; some limit download and upload speeds.
  • Fiber optic deployments are still expensive for ISPs (Internet Service Providers); however, the infrastructure can support many users on a single line without degradation in speed or quality.
  • Availability may be limited to certain areas due to initial high costs of deployment; the installation of fiber optic networks only makes sense in large metropolitan areas with a high concentration of internet subscribers.
  • Fiber optics for home and business does not affect existing services such as cable tv or phone lines and vice versa; however, traditional copper-wire networks may be affected if they are running on the same poles.

What does fiber optic internet run on?


Fiber-optic broadband is usually available in two formats: through a provider (offered by the phone company) or directly from an ISP. Whichever way it’s shown, the technology works similarly. Fiber lines are connected to optical network terminals (ONTs) installed on the consumer side.

An ONT converts the optical signal into an electrical signal that the home can use and vice versa to send data back to the ISP’s network. The fiber-optic lines are connected to a series of nodes, usually located in local substations. These nodes are connected using high-capacity trunk cables capable of carrying data to different network parts, which are connected to other nodes. The last node acts as an interface between the ISP’s network and your home or business, where it then uses electrical signals to provide access for up-stream and down-stream internet traffic.

Data is transmitted either through a series of lasers or through infrared waves, then changed back into the light at the receiving end.

What is connected by fiber optic cables?


A single line of fiber can carry up to 40,000 phone calls at one time, more than enough capacity for any business enterprise. To give you an idea of just how much bandwidth is, an average internet connection can carry up to 50 gigabytes (50,000 megabytes) of data every second.

Now consider that through a single fiber line, an Internet Service Provider can deliver almost unlimited amounts of bandwidth to the subscriber within a metropolitan area without having to worry about degradation in quality or speed. For use around the home, fiber-optic lines can deliver an unparalleled internet connection that is more secure, faster, and with little to no maintenance costs.
