DLS vs Fiber Internet

Choosing the right Internet connection for your home is one of the most important decisions you will make. Having reliable Internet access is no longer a luxury. It’s a necessity. And with so many options available for Internet services, how do you choose the best one?

Multiple factors affect the way you choose your Internet connection. You’re probably asking yourself some of these questions:

  • Can it deliver high-speed internet?
  • Does it work well with multiple devices?
  • Is it an expensive Internet provider?

If you’re trying to make a choice between DSL Internet and Fiber Internet, it’s key to know all the pros and cons that set each Internet connection apart. Both Internet options are different and almost entirely opposite to each other.

What it boils down to is figuring out which connection is better for you, your wallet, and your location. Here’s everything you need to know about DSL connections and Fiber Internet.

How Do Internet Service Connections Work?

Before making a choice between a DSL service or Fiber connection, it’s helpful to understand how Internet connections work. Broadband connections are complex, so it’s good to have basic knowledge about their inner workings.

Try to visualize the Internet as a tree. In this case, the tree trunk is like the Internet’s backbone – what holds Internet service together and transmits data around the world. And your neighborhood is like one of the tree branches – they are dependent on what the tree trunk can provide so they can survive.

An Internet connection is mostly made up of fiber-optic cables. They transmit data between cities and countries. And this applies to any type of connection, like DSL, cable, and Fiber.

In simple terms, even when you have weak dial-up Internet, the process of transmitting data is the same. Data travels from your computer to a server and back to your computer all through fiber networks.

This doesn’t mean that everyone has fiber Internet. The foundation of an Internet connection is made up of fiber optic cables.

But, the last bit of data that travels from your computer to your ISP switches over to copper cables. This slows down the process and makes some types of cable Internet speeds much slower than others.

What IS DSL?

DSL stands for digital subscriber line. It’s a type of Internet connection that transmits data through a phone line that gives you Internet access. Although there are many Internet services available today, DSL providers are still prominent.

Present-day connectivity continues to rely on telephone wires as a way to provide Internet service. This is the case with a DSL connection.

For DSL services to work, you need a modem and two copper wires within phone lines. Without those two components, a DSL service won’t be able to receive or transmit data.

DSL speeds vary but tend to be on the lower end. Upload speeds range from one to 10 Mbps, while download speeds range from five to 35 Mbps. unlike cable Internet, DSL Internet speeds are much slower and don’t perform well with online activities such as multi-player gaming.

DLS Pros and Cons

Pros of DSL Internet

Even though DSL speeds are not the best to stream Netflix, there are some positives you should consider before making a decision.

DSL Internet Doesn’t Need New Wires

Remember that DSL depends on telephone lines, and they are everywhere. This type of connection doesn’t typically have problems with infrastructure.

It uses the same copper phone lines as your home phone (if you have one). And they are still widely available and used by a multitude of customers.

DSL Is Affordable

When you compare DSL vs. cable Internet and Fiber optic Internet, DSL wins the battle. Unlike cable and Fiber, a DSL connection is much more affordable.

Keep in mind that DSL won’t get you the fastest upload speeds or download speeds. Overall, you can expect to pay between $15 and $35 for up to 8 Mbps.

DSL Has a Dedicated Connection

Unlike cable Internet, a DSL connection doesn’t share connectivity with others. Cable Internet speeds are often influenced by the number of users that are connected at the same time. It’s what’s normally referred to as “Peak Hours,” or “Peak Times.”

It’s true that Fiber optic Internet and cable connections perform at faster speeds. But, cable service often suffers from slower speeds due to the number of users engaging online during peak times.

This is something that doesn’t happen with a DSL service; the bandwidth is not shared. Because of this, and the reliability of a telephone line, DSL is more consistent. DSL can’t promise faster Internet than fiber, but at least it’s dependable.

Cons of DSL Internet

Although a Digital Subscriber Line (DSL) is a consistent source of connection, it still has a few negatives you should consider.

Slower Speeds

If it wasn’t for the telephone cable itself, DSL Internet would be much faster. The problem is that a phone line can only reach up to 45 Mbps for download speeds. Whereas Fiber optic Internet can deliver between 250 and 1,000 Mbps.

There are also issues with distance. Depending on how far away you are from the central ISP office, you’re more prone to slower speeds and higher latency. The material of the telephone cable doesn’t help as it’s much thinner than a coaxial cable.

Because of this, Internet connections that depend on telephone lines have to use “repeaters.” The “repeaters” make sure that the signal stays strong throughout the three to five miles of separation between your home and ISP office. Otherwise, your download speeds would greatly diminish.

Limited Availability

DSL connections are not available everywhere. People that live in rural areas have a better chance of finding a satellite Internet provider than DSL.

This goes hand in hand with the distance problems. The farther you are from your ISP office, the slower the signal.

Data Caps

DSL plans tend to have data caps implemented in the service. That means that whenever you reach the data that your plan comes with, DSL Internet providers can throttle your service and slow everything down to prevent you from going over that much more. That, or they’ll just charge you for the extra data at the end of the billing cycle.

Why Is DSL More Expensive Than Fiber?

If you’re trying to figure out whether you want to go with Fiber optic Internet or DSL, you’re probably considering costs. And the thing about DSL is that, in the long run, it’ll cost you more per Megabit than Fiber optic Internet. Here’s why.

  • DSL costs more to provide. DSL is almost an outdated technology. Today’s demands overwhelm the capabilities of a DSL connection. This makes it more expensive to keep up with necessary changes. These include fixing and maintaining copper lines, investing in technical help for customers, and figuring out ways to increase Internet speed.

Consider a DSL Connection If:

  • You’re looking for a connection that’s faster than dial-up but not as expensive as Fiber optic Internet.
  • Your level of engagement online is mild and you don’t depend on the DSL connection for running a business or downloading large files.
  • You’re looking for a cost-effective solution for your Internet needs.
  • DSL is great for customers in rural areas that can choose this option over satellite Internet service.

What Is Fiber Optic Internet?

Fiber optic Internet is the most advanced technology available today for high-speed Internet. What sets Fiber Internet apart from other types of Internet connections is the way it transmits data.

Up until now, you’ve heard a lot about Fiber optic cables and their uses in other types of Internet services. What sets fiber optic technology apart is that it uses plastic fibers to transmit data in the form of light signals. That’s what makes Fiber optic have unbelievable high-internet speeds.

Pros and Cons of Fiber Internet Service

There’s no question that Fiber optic technology surpasses DSL and cable technology. And while the positives outweigh the negatives, you still need to consider both to make the best decision for you.

Fiber Optics Pros

Fiber Internet Offers the Best Speeds

Fiber Internet offers the fastest upload speeds and download speeds. In fact, Fiber Internet speeds range from 250 to 1,000 Mbps.

The Federal Communications Commission recommends users have Internet service that offers a download speed of at least 25Mbps. This gives you an idea of how fast Fiber is compared to other cable Internet providers.

Fiber Optic Internet Providers Focus More on Security

All Internet providers want their customers to feel safe online. But, they’re not always able to provide the security that you’re looking for with other types of broadband Internet options or a cable Internet service.

When you compare DSL vs. Fiber Internet, it’s easy to see how advanced Fiber technology really is. Because Fiber optics don’t radiate signals, breaches can’t occur. The technology itself makes it impossible for anything to pass through.

Plus, what’s great about Fiber optic networks is that you don’t need hardware in multiple locations. Instead, you can keep it in a central location which enhances regulations and privacy issues.

Long-Term Cost Effectiveness

Initially, Fiber will seem like the most expensive option. In the long run, the maintenance and capacity for scalability will outweigh the initial investment.

Fiber Optics Cons

Prone to Physical Damage

A lack of coaxial cables already makes Fiber technology the clear winner of all the Internet options available. However, because Fiber is thinner and lighter, it makes it very delicate to handle.

Because the cables are so thin and few, if one is cut during a renovation, it jeopardizes a greater number of people. Plus, Fiber optic cables are prone to radiation damage and chemical exposure.

Infrastructure Costs

Lack of proper infrastructure creates limitations on Fiber Internet availability. Fiber technology requires specific installation. And it is expensive.

Fiber endpoints and connection nexuses require special equipment and setup. And that means that if there’s ever any damage to the cables, it’s a higher cost to fix it.

Consider a Fiber Internet Connection If:

  • You want faster Internet speeds. Fiber Internet provides symmetrical bandwidth. Basically, it means that both your upload speeds and download speeds are the same.
  • You want to increase Internet security.
  • You want an Internet that’s reliable and less prone to outages.

Is Fiber Internet Better?

Overall, yes. It’s difficult to compare other types of cable Internet services, or dial-up, to what Fiber technology can do.

And because fiber doesn’t rely on a coaxial cable to give you Internet access, it automatically makes the quality better and a lot more reliable than what cable providers can offer. That, and the upload speed and download speed surpass all the other types of Internet.

The Bottom Line

Ultimately, you’ll have to go with the Internet service that works best for you. It will always come down to what’s available in your area and what you feel is affordable.

Cable Internet providers and dial-up providers are common. You’re likely to find a lot of options for that type of Internet connection.

And while it’s important to pay attention to speeds, reliability, and security; ultimately, there is no perfect service. Try to focus on what your needs are and go from there. In the end, what matters is that you choose the best Internet option for your household.
