Key takeaways

  • Fiber is faster, highly reliable, more durable, and great for cloud-based or real-time work.
  • Cable is cheaper to install and more accessible but can get slower during busy hours due to shared bandwidth and asymmetrical speed.
  • Fiber supports ultra-fast speeds (~10 Gbps+) and has the capacity to increase internet speed as usage expands.
  • Cable remains an option for basic internet needs and if there are limitations on fiber line installations.

Between fiber and cable internet, which option reigns supreme? Read through my detailed comparison as I break down their differences, best use cases, and pros and cons.

Choosing between fiber-optic and cable internet is a strategic decision that significantly impacts work, particularly for the use of high-bandwidth applications, in hybrid work environments, and for organizations that rely on cloud-based systems. While both technologies are reliable, they differ in network performance, scalability, and long-term viability.

Having experienced both types of internet lines for both my personal and professional use, I would recommend going for a fiber connection, despite the higher upfront cost. It’s not only faster, but outages are rare as well compared to cable internet, thanks to its durability. However, I recognize that this isn’t always the best option.

Understanding fiber vs. cable internet

Before making a decision, it is essential to understand their key differences so you know which infrastructure best suits your organization’s needs. Here’s my straightforward comparison of these two internet technologies:

Fiber

This type of internet line makes use of glass or plastic strands to transmit data as light pulses. Fiber internet is more popular among those who use cloud-based systems, as the fiber-to-the-premises (FTTP) process ensures data integrity from the backbone to the endpoint, resulting in high-speed communications.

Cable

Cable has been around since the 1990s, initially designed for televisions and later evolved into a technology for transmitting digital data. It utilizes radio frequency (RF) signals over copper-based coaxial lines, employing data-over-cable service interface specification (DOCSIS) protocols.

Fiber internet: Pros and cons

It’s been five years since I’ve made the switch from a copper line to a fiber connection for our home internet, and I’ve seen significant improvements. However, it’s not always the right solution, as needs and situations of every person or household vary. To help you decide whether fiber internet is also what’s best for you, I listed down the advantages and disadvantages of using it:

Pros

  • Symmetrical speeds deliver equal upload and download speeds, which are crucial for high-internet use (e.g., large file uploads or hosting).
  • Having high bandwidth enables users to handle multiple high-demand uses and workloads without compromising on performance.
  • It can easily be upgraded to more than 10 Gbps as your business needs grow.
  • Low latency, often under 10 ms, works best for real-time applications like interactive remote support, virtual desktops, and even gaming.
  • It’s more weather-proof and reliable, unaffected by electromagnetic interference and safe from changing weather conditions.
  • Fiber cable is a long-term investment, as it can support decades of use and increasing data loads, as in an enterprise.

Cons

  • ❌Fiber infrastructure is not widely available, especially in rural, suburban, and underserved areas, so it may not even be an option for some, let alone a default choice.
  • ❌It has higher installation costs due to the complex process of laying fiber, which involves trenching, permitting, and the use of specialized equipment.
  • ❌Installation and implementation can take time, as there is a need to coordinate with city utilities or secure approval to access private properties.
  • ❌This type of cable internet may be overkill for teams or organizations that don’t need a fiber’s full capacity or can operate with low data usage.

Cable internet: Pros and cons

The cable internet was first in terms of commercial availability and infrastructure development. And while it is widely used across the globe, like the fiber internet, it’s not the ideal option for everyone. Learn what makes cable internet great, as well as its drawbacks, to know if it is the right technology for you.

Pros

  • Cable internet is sufficient for basic everyday use, such as email and chat, casual browsing, video or audio streaming, and general software as a service (SaaS) applications (e.g., project management tools, social media).
  • It is more widely available, being accessible in most urban and suburban areas, thanks to existing TV infrastructure.
  • Unlike fiber, cable internet requires a lower upfront investment because it’s faster to install, and the necessary infrastructure is usually already in place. Internet service providers normally need only a few days to install and activate a cable line.

Cons

  • ❌Having asymmetrical speeds (download is faster than upload) can result in bottlenecks when conducting remote backups, uploading videos, and facilitating VoIP phone systems.
  • ❌One of the biggest drawbacks is that bandwidth is shared with nearby houses or establishments. This often causes connectivity issues during peak hours, especially in densely populated areas.
  • ❌It has high latency, causing delays in data transmission. Aside from this, jitter also affects internet use, resulting in glitches, freezing, or echoing during video calls or gaming.
  • ❌Coaxial cables are susceptible to electromagnetic interference; hence, users may experience outages more frequently. This is probably the main reason why I switched from cable internet to fiber connection.

Cost comparison: Fiber vs. cable internet

One of the differences between cable and fiber internet is the cost. It is important to keep in mind that affordability doesn’t guarantee efficiency, so just because it is cheaper doesn’t mean it should be your go-to choice. You must consider the long-term maintenance and other potential costs such as upgrades.

Costs
Fiber internet
Cable internet
Installation
Starts at $1,000
Up to around $300
Monthly fees
Between $100 and $1,500 per month
Between $50 and $300 per month
Upgrades
Replacement of optical network terminal (ONT) and Wi-Fi router upgrade
May require a new modem every 3–5 years or DOCSIS upgrade, which are pricier
Maintenance
Wiring repairs are rare, as fiber lines are more weather-proof and durable
Coaxial lines are prone to damage and may need to be replaced

Which type of internet connection is best for you?

Choose fiber internet if your team relies heavily on cloud-driven apps and systems and if you consider use cases such as video conferencing a vital part of your operations. If you also need to collaborate with remote team members in real time, this is the best choice. Lastly, businesses aiming for longer infrastructure stability with plans to scale usage up, fiber is the way to go.

Cable internet lines, being more affordable, are best suited for basic internet use, such as browsing websites, social media, and sending emails. It is also reliable enough if you’re only going to stream music and videos and play basic online games, but not for high-bandwidth online gaming.

I would recommend installing cable lines if you don’t have plans to increase usage and bandwidth. Otherwise, fiber is worth the initial investment for higher bandwidth and better performance.

Frequently asked questions (FAQs)

Which is faster: fiber or cable internet?

Fiber-optic lines provide faster internet speeds with symmetrical upload and download rates, starting at 1 Gbps. Cable lines, on the other hand, deliver asymmetrical speeds, which can cause delays. For instance, it can reach up to 1 Gbps download but only 50 Mbps upload.

Can I get fiber internet in my area?

It depends. Although I would highly recommend fiber internet, the truth is that it is not easily accessible. Check with popular ISPs like AT&T Fiber or Verizon Fios to confirm if they offer fiber internet services.

The good news is that there is another option in the form of cable coaxial lines, which have infrastructure ready in most areas, including rural or suburban areas.

What happens if the fiber line gets damaged?

Fiber is far more durable than copper lines. However, if it sustains damages (e.g., fiber cut due to road repairs or landscaping), it must be repaired by the ISP technicians. The ISPs usually handle the cost of repairs, but if it was the user themselves that caused the damage, there will be corresponding charges.
