What Is Fiber Optic Internet?

Fiber internet is a type of broadband transmitted over fiber optic cables, offering fast, reliable service. However, fiber internet isn’t as well-dispersed as many would prefer, thanks to last-mile infrastructure challenges. Read on to learn more about the benefits of fiber optic internet, what to consider if you want to build your own and how SelectROW can help.


How Does Fiber Optic Internet Work?

Fiber optic internet starts with cables made up of bundled optical fibers. While copper cables send data as electrical impulses, fiber optic cables use light. Each optical fiber has a glass or plastic core to transmit the light, surrounded by cladding that reflects the light and keeps it from escaping the core.

Light travels through the cable in pulses that can travel long distances, with optical amplifiers boosting the signal along the way and preventing data loss. When the signal reaches its endpoint, an optical network terminal converts the light to electrical signals.

Before it can get there, the signal must cross the last mile — the final step that connects the endpoint consumer to the backbone of the internet. This step is typically the biggest stumbling block for fiber optic internet providers. In many places, the copper wiring that transmits telephone and television signals is the only existing infrastructure for last-mile connections. With a lower bandwidth and greater attenuation than fiber optics, copper wiring presents challenges for this crucial last-mile connection.


Different Types of Fiber Optic Last-Mile Connections

Establishing a fiber optic connection requires careful planning to solve the last-mile challenge. An internet service provider (ISP) must balance cost and customer desire to reach the best solution. Providers can choose one of the following types of fiber optic last-mile connections:

  • Fiber to the premise (FTTP): These are the most direct connections, establishing a fiber connection from beginning to end with no copper wiring. Since they call for new infrastructure for each endpoint, they are also the most expensive for the ISP.
  • Fiber to the neighborhood (FTTN): In this connection method, the fiber endpoint is a street cabinet positioned in a central location. From there, copper cables distribute the connection to individual locations. This method allows ISPs to use the existing copper infrastructure, helping keep initial costs down. However, customers at the edges of the connection may notice slightly lower speeds as the signal has to travel farther.
  • Fiber to the building (FTTB): An FTTB connection offers a fiber optic solution for buildings with multiple residents like apartments and commercial properties. It can function as a mix of the options above. Like FTTP, the fiber cable runs all the way up to a building where it connects to a distribution point, like the street cabinets that FTTN uses. The data might travel to the individual offices or apartments via fiber optics or pre-existing copper wiring.

What Are the Benefits of Fiber Optic Internet?

Investing in fiber internet lets providers offer benefits that outweigh other internet options, such as:

  • Faster download speeds: Most United States internet customers currently have download speeds between 10 Mbps and 25 Mbps. Fiber optic internet speed commonly reaches 1,000 Mbps, meaning fiber optic internet is good enough for five or more people to use high levels of bandwidth at the same time with no interruptions.
  • Matching upload speeds: Average broadband download speeds are about twice as fast as average upload speeds, while fiber offers matching upload and download speeds. With dramatically faster upload speeds, fiber internet is better for video calls, sharing high-resolution images and livestreaming.
  • Reliability: Fiber optic internet maintains speed and connectivity during peak hours, over long distances and during severe weather events. Additionally, fiber optic cables are more durable than the copper cables that DSL and cable internet use. Since the cables last longer without needing replacement, fiber internet customers face fewer maintenance outages.


Building Fiber Optic Broadband Infrastructure

Municipalities and ISPs interested in building their own fiber optic cable internet can start with the following steps:

1. Choose Your Method

When you’re ready to begin building, your first decision will be whether to choose an aerial or underground infrastructure.

Since aerial fiber runs cable over utility poles, it’s easiest for ISPs that already have an aerial infrastructure for their copper wiring. The costs of building an aerial infrastructure from scratch can be high, as the ISP will need to either lease the poles or build new ones. This method also faces geographical limitations and possible local restrictions.

While an underground infrastructure offers more options and flexibility, it still presents its own challenges. The Dig Once practice lets municipalities save money and minimize community disruptions, but it may mean facing delays in establishing your infrastructure. You’ll need to consider your route selection and the complications that might come with it if you opt for this method.

2. Hire Qualified Personnel

Consider what areas you already have staffed and where you’ll need to hire on or contract out. To build and maintain your infrastructure, you’ll need trained and licensed professionals who will:

  • Map out where to build the infrastructure.
  • Run heavy equipment.
  • Wire and maintain the network.

Municipalities that want to establish their own broadband infrastructure might consider partnering with an ISP to ensure they have all the necessary personnel.

3. Consider Your Return on Investment

Building a fiber optic broadband infrastructure requires a significant up-front investment. Before you start, it’s important to understand what to expect regarding a return on investment (ROI).

It might take a long time for ISPs to see a significant ROI, depending on:

  • Where they build their broadband network.
  • How many customers they serve.
  • What prices they charge.
  • What type of last-mile connection they choose.

Municipalities that invest in creating their own broadband infrastructure will likely measure their ROI differently. While an ISP is profit-focused, municipalities are typically more concerned with reaching community goals like attracting new residents and businesses and building a more robust economy.

4. Investigate Government Financing and Familiarize Yourself With Local Regulations

You can offset your investment with funding from government programs that encourage broadband expansion. The Connect America Fund (CAF) gives money to ISPs building their infrastructure in rural areas. Those ISPs can use the funding to connect more homes, broadening access.

Although rural municipalities can also qualify for CAF-funded grants to build or expand their broadband networks, those communities may face other roadblocks depending on their locations. Several states currently have laws prohibiting municipalities from building their own networks, leaving many rural towns without any broadband options. However, should the Community Broadband Act of 2018 pass, those restrictive laws will be nationally prohibited.
