What is fiber optic Internet

Fiber optic Internet is a type of high-speed broadband Internet access provided via fiber optic cable. This is the fastest type of cable Internet connection that can theoretically provide the speed of up to 1 Gigabyte. That’s because fiber cable has much higher data transmission rate comparing to regular copper cable.

How fiber optic Internet works



The signal is transmitted via fiber optic cables made from glass or plastic. The data is transmitted using light unlike with copper wires, where the signal is transmitted via electricity.

How fast is fiber optic Internet service



In order to understand how fast is fiber optic Internet service at your home, you can use special online services. These services help you check your connection and its average download and upload speed. But please note that your fiber Internet speed may vary. So the best bet would be to check the speed regularly, make notes and then calculate your average speed. The actual speed of your fiber Internet connection may not correspond to the speed declared by your Internet service provider. There are several factors that affect the actual speed including the quality of your modem and the quality of your line.

Types of fiber optic Internet connections



There are several types of fiber optic Internet connection depending upon where the optical fiber cable terminates. The two most popular ones are:

Fiber-to-the-Building (FTTB)


As the name tells, optical fiber cable runs from the Internet service provider data center to subscribers’ building only. And then the Internet is delivered to subscribers via common copper cable.

Fiber-to-the-Home (FTTH)


This is the most beneficial type of connection. In this case fiber optic cable runs into the user’s home. Such a connection provides broadband bandwidth with extremely high speed Internet access.

  • Besides fiber cable is not susceptible to electromagnetic interference, so the data can be transferred over greater distances with less interference and energy loss.


  • The biggest disadvantage of fiber optic Internet is the high cost of fiber optic cables. Another disadvantage of this type of broadband Internet connection is that it is not available in all residential areas.


  • Fiber optic Internet providers in the U.S.


    Fiber optic Internet availability is far from being perfect. Most states in the U.S. have several fiber Internet providers operating on the market.
