At the physical level, fiber internet is a technology that broadcasts internet data using light signals that pass through fiber enclosed in a cable. A fiber optic cable is made up of a bundle of glass threads that are capable of broadcasting messages modulated onto light waves.


What are the Differences Between Fiber and Other Types of Internet Options?


The biggest difference between fiber internet and other internet options is the speed. Fiber internet offers super-fast connection speeds that can reach up to 100 Mbps. Unlike other internet options such as cable internet or DSL (Digital Subscriber Line), fiber internet can be shared by many users without compromising the speed.


It is cheaper to install and maintain fiber internet in comparison to other internet options. The cost of installing and maintaining cable internet, for instance, depends on the speed at which it runs, thus the faster the connection, the more the monthly fee. The fact that fiber internet can be shared by many users while maintaining the same speed means that business organizations and homesteads can have super fast internet connections that are relatively cheap, which translates into more efficiency.

However, the above applies only to communities that have already adopted fiber internet. Many cities still have no infrastructure supporting fiber internet, and significant investment is required to get a city started.


Security problems are more prevalent in internet options such as cable or DSL than in fiber optic internet. Since most internet connections use the cable modem technology, there are more established methods to steal information through cable connections. However, fibers glass wire construction of optic cables coupled with the non-subscriber sharing quality provides new obstacles for hackers seeking to jump on your connection.



  • Bandwidth Capacity – Fiber Internet can provide much more bandwidth compared to other modern internet connections. This means that once fiber is installed, your internet will be more than fast enough for nearly any purpose for the foreseeable future. In addition, fiber allows a tighter port density that is better than cable or DSL internet.
  • Larger Transmission Distance – Most internet options have a limit on the range at which they can transmit data. However, there is no such limitatios with fiber internet since a single optic signal can be sent between two distant nodes even up to 100 Kilometers apart if the right equipment is used.
  • Immunity from Electromagnetic Interference – Fiber cables are immune from external radio frequencies that may significantly reduce the speed. in cable connections Also, fiber is non-conductive, meaning that if lightning strikes or a surge occurs the cables will still remain intact.
  • Ease of Installation – Fiber cables are lightweight and easy to transport over long distances.


  • Large Initial Capital and Scalability – Besides the large capital requirements, it takes a lot of time to construct a fiber optic broadband. The technology is not scalable as well. It only works efficiently in networks confined to one location where fiber optic lines can be installed without bending.
  • Another drawback is the fact t that fiber cables cannot be installed above the ground. This impedes tinstallation on a national or regional scale.


Is Fiber Internet Available Everywhere?

Starting a fiber network can be a large investment for both an ISP provider and a city. In some cases, in can also take several years to build out the network once funded. For these reasons, many cities still do not have any providers offering fiber internet. However, more and more cities are picking up on the trend, so even if you don’t have it now you should keep checking every year or so.
