How Do Fiber Optics Work in the Home?
Fiber optic internet brings the speed of light right into your home! It uses thin glass strands to transmit data as pulses of light, significantly faster than traditional copper cables.
-
The Outside Connection: A fiber optic cable runs from your internet service provider (ISP) to your home, either underground or aerially via power poles. This cable terminates in a small enclosure, often called a "clamshell," usually mounted outside your home. [Reference: How Does Fiber Internet Connect to Your Home?, Race.com blog, Frontier.com blog]

Entering Your Home: From the clamshell, the fiber optic cable enters your home, typically through a small hole drilled in an exterior wall. [Reference: Dgtl Infra]

The Optical Network Terminal (ONT): Inside your home, the fiber cable connects to an ONT. This device converts the light signals into electrical signals that your home network can understand. [Reference: How Does Fiber Internet Connect to Your Home?, Race.com blog]

Connecting to Your Network: The ONT typically has an Ethernet port. You connect your router to this port via an Ethernet cable. Your router then distributes the internet signal wirelessly (Wi-Fi) or through additional Ethernet cables to your devices. [Reference: Reddit r/googlefiber]
Key Components & Concepts
- Fiber Optic Cable: A bundle of thin glass strands that carry data as light pulses.
- Clamshell: A protective enclosure housing the connection point of the fiber cable to your home.
- Optical Network Terminal (ONT): A device that converts light signals from the fiber cable into electrical signals usable by your home network.
- Router: Distributes the internet signal within your home via Wi-Fi or Ethernet.
Speed and Reliability
Fiber optics offer significantly higher bandwidth and speed than traditional copper wire, enabling faster downloads, smoother streaming, and support for multiple devices simultaneously. Because it uses light, fiber optics are less susceptible to signal interference, resulting in a more reliable connection. [Reference: HowStuffWorks]
