Here's How to Install a Fiber-Optic Modem for Internet

When looking for an internet connection for your home, you might have come across the term fiber internet or Gigabit internet. Fiber internet is the fastest internet connection type available today. It uses fiber-optic cables to transmit data. Since the data transfer occurs through light pulses, fiber cables can carry large amounts of data quickly. Typically you get speeds of around 1 Gbps with a fiber internet connection.

It is important to note that most Internet Exchange Points (IXPs) across the world use fiber-optic trunk lines to connect with each other. However, when you get a standard cable internet connection, your service provider will run a traditional coaxial cable from the local IXP to your house. In the case of fiber internet, this last run will be of fiber-optic cable. As such, if you are getting a fiber internet connection, it essentially means that the final connection between your house and IXP is also using fiber. This last-mile fiber ensures high-speed connectivity.

Read on to find out how to install fiber internet and the equipment required. Also, learn about the top fiber internet providers in the country and their installation processes.

Fiber-optic internet equipment

Fiber internet cable

What does it do?

A fiber-optic cable utilizes small glass fibers to transmit data using light pulses. It connects your home with a nearby optical distribution box to access the internet.

How is it installed?

If a fiber network is not available in your home, you will have to run new cable lines from the distribution box to your home. You can run these lines either along the existing phone poles or underground.

Fiber-optic modem

What does it do?

A fiber-optic modem or Optical Network Termination (ONT) modem receives incoming optical signals over fiber-optic cables and converts them to digital signals that your digital devices can understand.

How is it installed? 

Usually, a technician from your service provider will install the fiber modem on the side of your house, or possibly in a garage or basement to serve as a connection point for fiber-optic cable.

Fiber router

What does it do?

Just like the fiber modem, the job of the fiber-compatible router is to keep up with the speeds provided by fiber-optic cables. These high-speed optical routers manage internet traffic between all your connected devices either wirelessly or via LAN channels.

How is it installed?

An Ethernet cable connects a fiber router to the modem or ONT. One end of the Ethernet cable goes into the back of the modem, while the other end goes into the WAN port available on the fiber router.

Bottom line

Fiber internet connection offers the fastest internet speeds of all other internet connection types today. With speeds of up to 2,000 Mbps, you can enjoy high-speed internet across multiple devices without any glitches. However, fiber internet differs in technology compared to DSL and cable internet. As such, its installation is also different. Knowing the installation procedure and the equipment required will give you a clear idea of what’s involved and any additional expenses that you may incur.

In fiber-optics, data transmission between two devices occurs through light particles that travel through small glass wires about the diameter of a human hair. These light signals are decoded to present information.

A fiber-optic Ethernet cable consists of thin wires made up of glass. A protective tube conceals these wires to protect them from the outside environment. The purpose of a fiber optic Ethernet cable is to connect two physical devices such as your router and a computer and enable high-speed data transmission between them.
