VDSL 2, short for Very High Bit Rate DSL 2, is a type of Internet
connection that uses the phone line, much like DSL. However, VDSL 2
uses 30 MHz of spectrum, has speeds of 100 Mbps, and has a range of
12,000 feet. These high capabilities allow for data to be sent in
larger volumes, at a much faster speed, and over longer distances. It
is no surprise why people are gaining interest in VDSL 2 for their
Internet service.
What is the Difference between ADSL, ADSL 2, VDSL, and VDSL 2?
- ADSL stands for Asymmetric digital subscriber line. It is the
weakest and slowest of these four forms of DSL. ADSL speeds will never
surpass 8 Mbps downstream and only 1 Mbps upstream. The unbalanced
rate of receiving and sending data is what makes the system
asymmetrical. The range for ADSL can reach around 15,000 feet from the
central office.
- ADSL 2 is similar to ADSL and typically the modems can be
interchangeable. The difference is that ADSL 2 offers a downstream
rate of up to 25 Mbps, while the upstream rate remains the same as
regular ADSL, at 1 Mbps. The range of 15,000 feet from the central
office also remains the same.
- VDSL is a different type of DSL that can offer customers up to 100
Mbps downstream and 50 Mbps upstream. The range from the central
office is 5,000 feet, more limited than ADSL and ADSL 2. VDSL is
mostly used in very densely populated and condensed cities in Asia
because of its lack of distance.
- VDSL 2 is currently the most advanced version of all DSL
connections. Not yet offered in most areas of the country, VDSL 2
offers a symmetrical upstream/downstream rate of 100 Mbps, with a range
from central office of 12,000 feet. VDSL 2 offers the very fastest
speed, with a strong distance range, for a highly desired service
around the world.
