You’ve probably heard of DSL, which is a high-speed Internet service. DSL stands for “digital subscriber line.” This means that broadband (high-speed) Internet is delivered to the user via his/her existing home phone line.
You’ve probably heard of DSL, which is a high-speed Internet service. DSL stands for “digital subscriber line.” This means that broadband (high-speed) Internet is delivered to the user via his/her existing home phone line.
But, did you know there are other types of DSL? These types are offshoots of the original DSL technology, and have improved in speed and performance for the user.
One of the best types of DSL is VDSL. VDSL stands for “very-high-bit-rate digital subscriber line,” and users can choose from regular VDSL and VDSL2. VDSL2 is currently the most advanced type of DSL broadband Internet available. We’ll focus on the standard form of very-high-bit-rate digital subscriber line.
VDSL vs. SDSL
SDSL stands for symmetric DSL, because the upload and download speeds are equal. One of the biggest ways to distinguish VDSL vs. SDSL is speed. On average, SDSL download and upload speeds max out at 2.3 Mbps. VDSL download speeds, on the other hand, can reach up to 52 Mbps. And VDSL upload speeds can reach 16 Mbps.
VDSL and SDSL also differ in terms of distance. Even though VDSL beats SDSL in terms of speed, users can receive SDSL up to a maximum of 22,000 feet from the central office. VDSL can only reach a maximum of 4,000 feet. Very-high-bit-rate digital subscriber line access also includes phone support and symmetric DSL does not.
VDSL vs. ADSL
Another one of the most popular types of DSL is ADSL. ADSL stands for asymmetric DSL because the upload and download speeds are not equal. ADSL offers the slowest max upload speeds for DSL – 800 Kbps. But, it offers relatively fast download speeds of up to 8 Mbps.
When it comes to VDSL vs. ADSL, VDSL is the clear winner in terms of speed. Because of its high bit rate, VDSL can offer significantly faster speeds. However, when it comes to distance, ADSL can reach further. Both VDSL and ADSL can support a home phone line.
