How do DSL, cable, fiber, and internet connections differ?
A wired internet connection is based on network cabling technology which connects computers and other devices. Network cabling was invented in 1973, and since then has advanced tremendously, allowing faster data transfer over the years. As a result, the differences between DSL, cable, and fiber—the wired internet technologies available today—are so confusing. Read on to learn about the main differences between these three types of internet wired connection.
DSL, cable, and fiber differ in how they deliver internet to your home. DSL internet runs through standard phone lines (folks from the early 2000s will likely remember the distinct dial-up sound when connecting to the internet, which also meant you could not use the landline while the internet was in use). Cable transmits data through copper coaxial cables (with an inner conductor and a protective outer jacket). Fiber-optic internet, also known as "fiber", transfers light signals along thin strands of glass.
Cable is usually faster than DSL as it has more bandwidth. Fiber internet, on the other hand, offers faster speeds and higher capacity overall. This is made possible because light signals travel faster and carry more information than electrical signals. In addition, fiber provides a reliable connection with less interference as it's more durable and less susceptible to degradation over long distances.Which is the fastest internet and is better overall? And are there downsides to fiber internet?
Fiber internet offers faster speeds and is more durable with less interference. However, cable internet can still provide an excellent solution to many. This is because suitability depends on your needs, budget, and circumstances.
If you are wondering which internet service is best for you, you may want to consider these facts:
Do I need a special router for fiber internet, and is the AT&T Gateway different from the router?
Yes, to use fiber internet, you'll need a dedicated router, known as a fiber-optic router. A router provides internet connectivity, and fiber-optic routers are designed to maintain high-speed data transmission. Usually, your internet service provider will provide this router, but you can also purchase one yourself if you prefer.
However, the AT&T Wi-Fi Gateway combines the functions of both a modem and a router. This seamlessly supports a home full of smart devices and your most demanding Wi-Fi needs. When choosing to install AT&T Fiber, the AT&T technician will determine if a new Wi-Fi gateway is necessary and provide one if needed. Learn more about AT&T Internet equipment
Is cable cheaper than fiber?
Prices can vary widely depending on the internet service provider, the speed of the connection, and the area in which you live. We recommend shopping around and comparing prices before deciding on a new fiber internet service provider or upgrading your current internet plan for your home internet.
