What's the Difference Between Fiber and Regular Internet?

Technology comparison

When people say 'regular internet,' they usually mean cable (coax) or DSL (phone lines). Fiber is fundamentally different technology — not just a faster version of what you have.

DSL: The Oldest Generation

DSL runs on existing telephone copper lines. It's widely available in rural areas but limited in speed — typically 5–100 Mbps download. Performance degrades the further you are from the telephone exchange. For most households with streaming and multiple devices, DSL is no longer adequate.

Cable: The Most Common Upgrade

Cable internet uses coaxial cable (the same infrastructure as cable TV). It's faster than DSL — up to 1 Gig in some markets — but the network is shared with your neighbors. During busy hours, speeds can drop noticeably. Upload speeds are especially limited: typically 10–35 Mbps.

Fiber: The New Standard

Fiber-optic internet transmits data as light through glass or plastic fibers. It's not affected by electrical interference, doesn't degrade over distance, and isn't shared with neighbors. Symmetric speeds mean you get the same bandwidth for uploads as downloads.

The Real-World Impact

On paper, a 200 Mbps cable plan sounds similar to a 200 Mbps fiber plan. In practice, fiber delivers that 200 Mbps consistently at all hours, while cable might deliver 120 Mbps during peak evening hours. Fiber also has lower latency, which matters for gaming, video calls, and real-time applications.

What Most Homes Should Consider

If you have cable and it's working fine, you may not feel compelled to switch. But if you've noticed slowdowns in the evenings, poor upload speeds, or frequent service interruptions, fiber is a meaningful upgrade that will likely remain relevant for the next decade or more.
