What You Need to Install Fiber-Optic Internet

And why fiber is the best connection there is

Fiber-optic internet connections are by far the fastest and most reliable type of internet connection you can choose, but getting those precious beams of internet light to your devices can be quite an ordeal. For those taking their first steps into the world of fiber-optic internet—or those who are still considering it—here’s all you need to know.

How does fiber-optic internet work?

Fiber is already an essential part of everyone’s internet experience, as the backbone of the internet is built from huge fiber-optic cables. Fiber-optic cables are made from thin fibers of glass or plastic that transmit information as pulses of light across long distances. Compared to metal wires, they can carry much more data, they are much less prone to data loss, and they are completely immune to electromagnetic interference (as you might get from solar storms). Fiber-optic cables cross continents and oceans—whether they’re at the bottom of the sea or just beneath your feet, they can be counted on to do their job reliably.

Tubes full of light

In fiber-optics, information is transmitted as pulses of light. The inside of a fiber-optic tube acts like a mirror, bouncing the light off of the inside walls and down the tube, toward its destination. Since information is literally moving at the speed of light, you can move a lot of data really fast. There are lots of different types of fiber-optic cables—some are more durable, some travel longer distances—but all of them transfer data quickly and reliably.

All internet traffic will travel over fiber-optics at some point, but ideally you’d want fiber to reach all the way to your home. Fiber to the home (FTTH) not only gives you the fastest, most reliable connection currently possible but also saves internet service providers (ISPs) money in the long run with much less maintenance and fewer customer complaints. As such, fiber internet plans are often the same price or cheaper than other types of connections in the same area. It’s a win-win!

The last mile

Unfortunately, most fiber networks don’t reach all the way to the home. This distance between the core fiber lines of the internet and internet users’ homes is often referred to as the “last mile” (even though the actual distance will vary). The last mile of connection is usually filled by coaxial cables, phone lines, or wireless transmissions. This is the difference between fiber internet and other types of internet. Fiber customers have fiber all the way from their home to the rest of the internet infrastructure. Cable or DSL customers will have fiber most of the way between their house and the rest of the network, but the last mile to their home will be made over coaxial cables or copper phone lines.

These older technologies become the bottleneck, making your speeds lower, your latency higher, and your connection much less reliable. That’s why even though everyone’s data travels mostly over the same fiber-optic cables, some people end up with a much better overall experience.

Why fiber is so great

So, why should you care about fiber? Besides being the cool, cutting-edge technology for accessing the internet, there are a lot of very tangible benefits that fiber offers that other internet technologies can’t match. The main advantages of fiber are its high download speeds, symmetrical upload speeds, reliability, and scalability.

High download speeds

Since fiber is used to connect entire continents with billions of internet users, it should come as no surprise that fiber is the fastest choice for connecting your home and all your devices. Most fiber plans nowadays offer 1 Gbps (1,000 Mbps) speeds, which is more than most people can use—even if they invite all their friends over to use their Wi-Fi.

Many cable internet plans can also reach 1 Gbps, but the two technologies are by no means equals. Cable speeds will probably continue to increase as we push the technology to its physical limits. Meanwhile, fiber isn’t even breaking a sweat yet. As home internet speeds increase, the gap between cable and fiber is only going to get wider.

Symmetrical upload speeds

Cable download speeds are roughly on par with fiber, but uploading on a cable connection reaches only a fraction of those speeds. Fiber, on the other hand, has symmetrical upload and download speeds. This means that if you can download at 1 Gbps, you can upload at 1 Gbps as well.

Most internet activities, like watching video, reading the news, or just web surfing, require very little upload speed, so download speed is the important factor. However, as more people start using the internet for video conferencing and livestreaming, upload speed becomes more important. Nothing comes close to fiber in terms of upload speed.


Fiber connections don’t just have the highest advertised speeds; they also maintain those speeds more reliably than other connections. Most types of internet are vulnerable to certain types of interference. Here are some examples:

  • Cable internet is slower when there’s more internet traffic in your neighborhood.
  • DSL internet slows down the farther you get from the provider’s central office.
  • Fixed wireless signals require direct line of sight to the transmitter, so they can be blocked by trees or other obstructions.
  • Satellite internet can be disrupted by the weather.

Fiber doesn’t suffer from any of these problems. It also doesn’t require as much maintenance as other types of internet. This means that you don’t have to deal with outages from old cables being replaced nearly as often as you would with cable or DSL.


Fiber is certainly the best internet you can get right now, but it’s also the best option when looking to the future. Since fiber uses light instead of electricity to transmit its data, it uses much higher frequencies and loses less energy over long distances. This means that fiber can carry more information much farther than is physically possible across metal cables.

Fiber-optic cables are also sometimes installed with what is known as “dark fiber.” Dark fiber is extra fibers in the cable that aren’t initially used. As the amount of internet traffic in an area increases, dark fibers can simply be turned on to provide additional capacity, rather than having to dig up the cables and lay bigger ones.

Why don’t I have fiber now?

Although fiber has many advantages over other types of internet, there are several challenges to widespread fiber reaching your home.

Installation costs

While fiber-optic technology has been around since the 1960s, it’s still expensive to install. Much of this cost is simply digging the trenches to bury the cables underground. Digging a trench isn’t as big of a deal when you’re laying a major internet line to connect a city with millions of potential customers. Unfortunately, digging a trench to a small neighborhood or a single house gives a much smaller payoff to the provider. This is why the last mile of the network is often built with cheaper and less reliable technology.

Google Fiber attempted to overcome this problem by developing ”microtrenching” or “shallow trenching” methods, where instead of digging a deep, foot-wide trench, the company simply carved a narrow groove into a road, just wider than the cable and only a few inches deep.

Unfortunately, this experiment failed spectacularly, with cables becoming damaged and even popping up out of the road, tripping pedestrians in Louisville, Kentucky.1 These problems eventually caused Google Fiber to pull out of Louisville completely. Google also had to pay to repair all the roads damaged by the failed installation.

Short-term alternatives

Although fiber is currently the best long-term solution for residential internet, many other competing technologies offer connections that, while not as fast or reliable as fiber, are still enough to meet the immediate needs of most internet users.

While these alternatives make sense in the short-term, they can have serious consequences down the road. For example, after the bankruptcy of Frontier Communications, the company noted that one of the major factors that led to its bankruptcy was an underinvestment in fiber. The consequences of ignoring fiber shouldn’t have been a surprise since fiber has been the fastest and most reliable type of connection for decades. Rather, it was a choice by the company to focus on short-term goals instead of investing in the future.

Long-term roadblocks

Fiber is a good long-term investment, so it’s a popular choice for cities that want to invest in their own public broadband infrastructure. In 2020, the city in the US with the fastest average internet speed is Cedar Falls, Iowa, whose municipal fiber network delivered speeds over five-times faster than the nearest commercial ISP.2

Unfortunately, municipal broadband is restricted or banned in nearly half of the US, so this kind of long-term investment often can’t be done by cities or counties.3 That means that it’s up to ISPs to build their infrastructures with an eye to the future.

This is also easier said than done. Just as ISPs have slowed or stopped the expansion of municipal broadband, ISPs often get in each other’s way as well. One of the reasons Google decided to gamble on their disastrous microtrenching experiment in Louisville is that AT&T sued the city and county to prevent Google using their utility poles.4 Although AT&T lost the lawsuit, it spoiled Google’s plans and, in the end, meant that Louisville didn’t get Google Fiber.

How to self-install fiber

Since installing fiber most often requires laying a new cable and setting up specialized equipment, some fiber providers do not give the option for you to self-install fiber internet. You must have a technician come to your home to set it up for you, which can be very expensive. If your ISP doesn’t require a technician to set up your connection, these are the steps to self-install fiber internet:

  1. Locate your fiber network terminal.
  2. Connect the fiber terminal to the network box.
  3. Plug in your network box.
  4. Connect your device to the network box.
  5. Set up your home Wi-Fi network.

These steps are very similar to self-installing other types of internet, but with a few important differences. Let’s take a closer look at each one.

Locate your fiber network terminal

In order to install your own fiber internet, you first need to have an optical network terminal (ONT), also called a fiber network terminal or fiber jack, in your home connecting you to your provider’s network.

Unlike coax jacks or phone jacks, which are often plates installed flat against the walls, fiber terminals are typically bigger and blockier. They can range in size from just larger than a juice box to the size of a briefcase and are usually installed in out-of-the-way places like the corner of a room, inside a closet, or even out in the garage.

If you don’t have a terminal installed in your house, you’ll need a technician to come install one.

Safety tip

If your optical network terminal has loose fiber connectors, do not look into the end of the connector as this can cause eye damage. Refer to your terminal’s user manual to reconnect these cables properly.

Once you’ve found your terminal, make sure that the power light is on. If the light isn’t on, make sure the terminal is plugged in to a power outlet.

Connect the fiber terminal to the network box

The next step is to connect your network box or gateway to the terminal. Typically, this is done with an Ethernet cable, which should have been provided with the network box. Plug one end of the Ethernet cable into the port on the terminal, then plug the other end into the appropriate port on the network box. This is typically labeled “ONT” or “Fiber Jack.”

In some cases, particularly with larger terminals, the output of the terminal is wired to one or more jacks throughout the house. In this case, find an appropriate Ethernet jack (or in some cases, coax jack) inside the house and connect your network box to the jack.

Plug in your network box

Once your network box or gateway has been properly connected to your fiber terminal, connect the power cord to the network box and then plug it into a power outlet. As with a router, the lights should turn on and start blinking, eventually turning a solid color. This can take much longer for fiber service than other types of internet, sometimes up to 15 minutes.

If the lights on your network box are still blinking after 15 minutes, unplug the power, wait 30 seconds, and plug it back in. If it still doesn’t stop blinking after another 15 minutes, contact your internet service provider’s customer support.

Connect your device to the network box

Before you can set up your Wi-Fi network, you must connect a device to your network box or gateway. This can usually be done with a laptop, desktop, or even a phone.

Many network boxes will automatically create a default Wi-Fi network. The information on how to connect to this network is usually either printed on a sticker somewhere on the network box (often on the bottom) or in the manual.

If your box does not create a default Wi-Fi network during setup, you can connect directly with an Ethernet cable.

Set up your home Wi-Fi network

The final step in setting up your fiber internet is setting your home Wi-Fi network name and password.

How to get fiber to your area

Fiber is amazing and fiber is everywhere, but most houses in the US aren’t set up to use it yet. That “last mile” between your house and the rest of the internet makes all the difference and the task of bridging that gap ranges from difficult to herculean. Still, everyone’s gotta start somewhere, right?

How to get fiber to my house

If a fiber provider is already in your neighborhood, you might be in luck. Running a cable from your house to the curb is the smallest investment an ISP would have to make to connect you to its network and will usually be covered by the installation fee.

If the network is still a few blocks away, some ISPs might be willing to run a cable to your house for a much higher installation fee, but usually you have to wait until its network makes its way to your block.

In either case, it’s a good idea to contact your local fiber provider. Even if they’re not willing to run a fiber cable to your house yet, at least they’ll know that there’s interest in your area when they start expanding their network.

How to get fiber to my neighborhood

Having a fiber network in your city is great, unless you happen to live on the opposite side of town where it’s not available. Then it’s just frustrating. Fortunately, ISPs don’t usually make the massive investment of a new fiber network just to get a tiny pocket of customers. They want to expand to wherever they can get the most customers, which usually involves close cooperation with local city governments.

One of the best ways to show an ISP that there is interest for fiber in a particular area is to go to town and community meetings and ask about fiber internet. Better yet, talk to your neighbors and get them all to come with you and you can all express your desire for fiber internet together.

Community council members can pass your interest along to the ISP or, in many cases, the ISP might have employees at the meeting. Google Fiber, for example, often sends employees to community council meetings in areas where it’s expanding its network to share information and generate interest. If you’ve already got the interest, half their work is done.

How to get fiber to my city

If there are no ISPs in your city offering fiber service, you’ve got quite the daunting task. Although some ISPs are expanding their fiber networks, others, like Google Fiber, have cut back or halted their expansion altogether.5 Does that mean that all hope is lost?

There is still one other option: municipal fiber. Although ISPs are more likely to build fiber infrastructure in larger cities first, any city can build a municipal fiber network with enough community support. Cedar Falls, Iowa, had a population just over 40,000 when it built its fiber network.6 Mapleton, Utah, a town with barely 10,000 residents, is currently building its own fiber network as a public utility.7, 15 These networks are often paid for by bonds, which also means that they don’t increase taxes or take funds away from other important programs.8

Building a municipal fiber infrastructure can also have additional benefits. In 2015, the White House commissioned a study into the effectiveness of community-based broadband solutions. This study found that municipal broadband not only created fast, cheap, and widely available internet connections but also brought commercial competition and private investment to underserved communities.9 In this way, municipal broadband creates more choices for consumers and drives economic growth.

Even in the most technologically developed areas, public investment in fiber is one of the best ways to lower costs and increase competition. New York City recently announced plans to build a city-wide municipal fiber network, focusing on the most poorly connected areas first.10

Fiber access isn’t only a solution for dense urban areas. It can also be done in rural areas. In January 2022, the small town of American Falls, Idaho, announced that it would soon be offering fiber internet to all residents, free of charge.14 Giving every home in the city fiber access will help to bridge the digital divide in this area, allowing residents the same opportunities available in urban areas.

Municipal fiber networks can also be the seeds of larger projects. It’s no surprise that when Google Fiber announced that West Des Moines, Iowa, would be its first new city after four years of inactivity, it chose a city that had already laid down its own fiber infrastructure.11 This isn’t a new trend, either. Provo, Utah, the third city in the US to get Google Fiber, was chosen because Google was able to take over the city’s existing municipal infrastructure.12

If you build it, they will come.

Where are fiber networks expanding?

Fiber-optic networks are expanding all across the US, especially in densely populated urban areas. Additionally, increased federal funding for high-speed internet expansion is helping to bring fiber connections to rural areas that have historically been underserved by major internet providers.

Google Fiber is also on the move again after announcing West Des Moines as the first new Google Fiber city in several years.13 Google Fiber is also expanding in other areas like Salt Lake City, Utah; Omaha, Nebraska; Mesa, Arizona; and Austin, Texas.

In addition to Google Fiber, many large nationwide ISPs, especially those with aging DSL networks, are rapidly expanding their fiber coverage to keep up with demand from consumers. Many of these providers have also begun offering multigigabit connections as they race to be the provider with the highest residential fiber speeds.

With more people working and attending school from home than ever, the demand for fiber connections will continue to increase. This also means that you’re likely to see more and more fiber options in your area as ISPs try to fill these demands.

Fiber internet forever!

Fiber-optic internet has been around for almost 60 years, and although the digital landscape has changed dramatically, fiber won’t be going out of style anytime soon. It’s pretty hard to compete against the speed of light.
