Fiber-Optic Internet vs. Cable Internet
Fiber and cable can both deliver high-speed internet. The difference comes down to how they connect your property, the upload and download speeds available, and the service you receive.
Here’s what to know when choosing a connection for your home or business.
What is cable internet?
Cable internet typically uses a combination of fiber-optic and coaxial cables. The coaxial connection carries data to your property using radio-frequency signals.
A cable modem connects to the provider’s network. A separate router, or a combined modem and router, connects your devices through Wi-Fi or Ethernet.
What is fiber-optic internet?
Fiber internet carries data as pulses of light through optical fiber. With fiber-to-the-home or fiber-to-the-business service, that fiber connection reaches your property.
An optical network terminal, or ONT, converts the optical signal into a connection your router and devices can use.
Is fiber faster than cable?
Both technologies support high download speeds. Actual speeds depend on the provider, available plans, network, and equipment.
Upload speed is an important part of the comparison. Many cable plans offer lower upload speeds than download speeds, although some upgraded cable networks offer symmetrical service.
Planet Networks offers equal upload and download speeds, helping you send large files, back up photos, and join video calls without a slower upload tier holding you back.
Why choose Planet Networks fiber?
- Equal upload and download speeds: Get a connection designed for sending as well as receiving.

Like cable service, fiber internet still depends on powered equipment. It is not automatically immune to power outages, physical damage, or service interruptions.
