The main differences between DSL and VDSL

DSL and VDSL have more differences than just naming. In this practical tip, we summarize the most important of them for you.

DSL vs. VDSL: The transmission rate

The first difference is in the possible transfer rate. With a conventional DSL connection, a transmission rate of up to 16, 000 kbit / s (16 Mbit / s) is possible, whereas VDSL allows bandwidths of up to 100, 000 kbit / s (100 Mbit / s). This not only results in higher download rates; VDSL can also upload data faster.

DSL vs. VDSL: I'm staring at TV

Some Internet providers, such as Telekom or Vodafone, offer so-called IP TV. Here the television signals are not received via antenna or satellite, but via the Internet line. The transmission rate of DSL would be too weak here. With VDSL, however, HD content can also be received via the Internet line at a corresponding transmission rate. VDSL also offers the technical requirements for other demanding Internet applications.

DSL vs. VDSL: The technology

DSL is only transmitted via copper cables. There are disadvantages due to various physical aspects. To put it simply: With copper cables, the signal quality and thus the transmission rate deteriorate with every meter. VDSL, on the other hand, uses a new type of transmission medium: fiber optic cables. There is also a signal drop here, but in contrast to copper cables this is very low. While copper cables are a physical transmission medium, glass fibers are an optical transmission medium.

DSL or VDSL?

VDSL is clearly superior to DSL because it offers both higher transmission rates and future-proof technology. Unfortunately, VDSL is not yet available everywhere. If you are thinking of switching from DSL to VDSL, it is best to speak to your Internet provider - they can give you more information about whether VDSL is available to you or whether it will be available in the near future.
