In today’s connected world, choosing the right internet service to power your connected devices is more important than ever. With multiple options like fiber and cable internet growing in availability, understanding the differences can help you make the best choice for your home or business. Explore our answers to the most-asked questions about fiber and cable internet and determine the best option for your needs.

Understanding Fiber and Cable Internet

What Is Fiber Internet?

Fiber internet uses fiber-optic cables made of thin glass or plastic strands to transmit data as pulses of light. This allows for incredibly fast data transfer speeds and higher bandwidth capacity.

Learn more about fiber internet and how it works.

What Is Cable Internet?

Cable internet delivers data through coaxial cables—the same ones used for cable television. These cables use copper wires to transmit data via electrical signals.

Speed Comparison: Fiber vs. Cable Internet

Is Fiber Faster Than Cable Internet?

Yes, fiber optic internet typically offers faster speeds than cable. Fiber is capable of delivering symmetrical upload and download speeds up to 1 Gigabit per second (Gbps) or more.

Fiber Optic vs. Cable Internet Speed

  • Fiber Internet Speeds: Typically up to 1 – 2 Gbps for both uploads and downloads.
  • Cable Internet Speeds: Download speeds up to 500 Mbps, with significantly slower upload speeds.

This means activities like streaming 4K videos, online gaming, and video conferencing are smoother with fiber.

How Does Fiber Internet Work Compared to Cable?

  • Fiber Internet: Uses light to transmit data, which is less susceptible to interference and results in less signal loss over long distances.
  • Cable Internet: Uses electrical signals over copper wires, which can degrade over distance and are susceptible to electromagnetic interference.

Reliability and Performance

Is Fiber Internet More Reliable Than Cable?

Yes! Fiber optic cables are less prone to outages and can withstand harsh weather conditions better than cable. They are also immune to electromagnetic interference, which means it’s more secure than cable.

Does Fiber Internet Have Better Upload Speeds Than Cable?

Yes! Fiber offers symmetrical speeds, meaning uploads are as fast as downloads. Cable’s upload speeds are often a fraction of its download speeds. Upload speeds are important for online activities like videoconferencing, gaming and file sharing.

Discover why switching to fiber could enhance your online experience.

Bandwidth and Latency

Does Fiber Offer Higher Bandwidth Than Cable?

Fiber has a much higher bandwidth capacity, allowing multiple devices to connect without sacrificing speed. That’s why many describe fiber as “future-proof.”

How Does Latency Compare Between Fiber and Cable Internet?

Fiber generally has lower latency than cable, which is crucial for real-time applications like online gaming and video calls.

Availability and Installation

What Factors Affect the Availability of Fiber vs. Cable?

  • Cable Internet: Widely available due to existing cable TV infrastructure.
  • Fiber Internet: Availability is growing but is still limited in some areas due to the need for new infrastructure.

While most fiber internet providers focus on servicing densely populated urban areas first, Mercury Broadband is actively expanding fiber access in rural regions of the Midwest.

What’s the Installation Process Like for Fiber vs. Cable Internet?

  • Fiber Installation: Involves installing new fiber-optic lines directly to your home. Installation in the home typically takes a few hours and is completed by a professional technician.
  • Cable Installation: Utilizes existing coaxial cables, making it quicker and easier to install yourself, but potentially less advanced.

Can Cable Internet Be Upgraded to Fiber?

Upgrading requires installing new fiber-optic cables outside the home. Installing this infrastructure can be expensive, which is why fiber is not yet available in all areas, particularly rural and remote regions. However, upgrading comes with substantial benefits.

Cost Considerations

Is Fiber Internet More Expensive Than Cable?

Initially, fiber plans may be priced higher due to infrastructure costs, but the gap is narrowing. Considering the speed and reliability, fiber offers excellent value compared to cable and other types of internet.

What Is the Cost Difference Between Fiber and Cable?

  • Fiber Plans: Starting at $79/month with Mercury Broadband.
  • Cable Plans: Prices vary but may offer lower speeds at similar prices.

Which Is Better for Your Needs?

Is Fiber or Cable Better for Streaming and Gaming?

Fiber’s higher speeds and lower latency make it ideal for streaming high-definition content and competitive online gaming.

Is Fiber or Cable Better for Large Households?

Fiber’s higher bandwidth can handle multiple devices simultaneously, perfect for busy households and smart homes.

Does Cable Have Any Advantages Over Fiber?

Cable has a few advantages, though the performance benefits of fiber often outweigh these factors.

  • Availability: Cable is more widespread in certain areas.
  • Bundling Options: Cable providers may offer TV and phone services in a single discounted package.

Future-Proofing Your Internet Connection

Is Fiber More Future-Proof Than Cable?

Yes! Fiber infrastructure can support increasing internet demands without significant upgrades, making it a long-term connectivity solution.

What Are the Long-Term Benefits of Fiber Over Cable?

  • Scalability: Easily accommodates future speed increases.
  • Durability: Less maintenance and longer lifespan.
  • Enhanced Value: Homes with fiber internet typically have higher property value due to the appeal of very high speed internet among buyers and homeowners.
