VDSL (Very-High Data Rate DSL)

Very-high data rate Digital Subscriber Line (VDSL) is one of the newest of the DSL technologies, which offers speeds up to 25 Mbps downstream and 3 Mbps upstream. The gain in speed can only be achieved at short distances. VDSL is not yet very common because there is not an international standard for VDSL.

VDSL is actually proposed for shorter local loops that can provide up to 53 Mbps downstream and up to 2.3 Mbps upstream. VDSL’s bandwidth allows for high definition television. One downfall of VDSL is that even though it is a high speed technology it has a very limited range. VDSL is currently working to develop a technology that promises much higher data rates over relatively short distances.

VDSL is a relatively new technology that does allow much higher symmetric and asymmetric bit rates. VDSL also has the capability to simultaneously transmitting ISDN services, but with much smaller ranges of course. If you decide on VDSL it may require the deployment of optical links and possibly the setting up of active equipment in the local loop.
