Switching to Fiber

Switching to Fiber Internet: What You Need to Know About Equipment Changes

If you’re upgrading from DSL or cable internet to fiber, you might be wondering what equipment changes are necessary. Some people think they need a special “fiber router,” but in most cases, that’s not true. Let’s clear up the confusion and help you understand what really changes when you switch to fiber internet.

How Fiber Comes to Your Home

Unlike DSL or cable, which use phone lines or coaxial cables, fiber internet sends data through thin glass fibers using light signals. Here’s how it reaches your home:

  1. Fiber from the Utility Pole or Underground – The fiber optic cable runs from the main network to your home.
  2. Outside Box (Patch Panel) – The fiber cable connects to a small box mounted on the outside of your house. This box is simply a junction point for the fiber.
  3. Inside Connection to the ONT (modem) – From the outside box, the fiber is routed inside to a device called an Optical Network Terminal (ONT).  This replaces the cable or DSL modem.
What is the ONT and Why Do You Need It?

The ONT is the key piece of equipment provided by your fiber internet provider. It’s similar to a cable modem, but for fiber. The ONT’s job is to convert the fiber signal into standard Ethernet, which is what your home network and Wi-Fi devices understand.

  • The ONT must be provided by the fiber company, as it is designed to work with their network.
  • It has an Ethernet port, just like your old DSL or cable modem.
Do You Need a New Router?

Your existing router will likely still work with fiber, connecting to the ONT with an Ethernet connector via the WAN or Internet port on the router.

  1. No Special “Fiber Router” Needed – The ONT handles the fiber connection, and it provides standard Ethernet output. Any router with an Ethernet input can connect to it.
  2. Speed Limitations on Older Routers – If you have signed up for gigabit speeds (1000 Mbps), your old router may not be fast enough to take full advantage, but like an older automobile, will go fast enough.
  3. Wi-Fi Performance – If your router is more than a few years old, it may not support the latest Wi-Fi speeds, meaning your wireless devices might not experience the full benefits of fiber.  Again though, most downloads and streaming apps will use less than 10% of your internet capacity, so there is no need to upgrade immediately.
ISP-Provided Router vs. Your Own Router

Some fiber providers offer or rent a router and Wi-Fi access point. Whether you should use it depends on your situation:

  • If you are comfortable with technology and already have a good router, you can use your own to avoid rental fees.
  • If you prefer a simple setup with ISP support, you may choose to use their router, especially if it’s included in your plan.
Key Takeaways
  • You do NOT need a special fiber-compatible router. The ONT converts fiber into Ethernet, just like a modem does for cable or DSL.
  • Your current router will likely work, but if you have purchased gigabit speeds, an older router may not handle the full speed.
  • Your WiFi may limit your speed unless you are using the latest versions.  This usually doesn’t matter.
  • The primary connection is Ethernet, from the ONT to your router, just like cable or DSL.
  • Your ISP may provide a router, but you can often use your own if it meets speed requirements.

If you’re unsure whether your current router will work at full speed, check its specifications or ask your fiber provider for recommendations. With the right setup, you’ll be able to enjoy faster, more reliable internet with minimal hassle!
