The acronym VDSL (Very high bit-rate Digital Subscriber Line) refers to the new Internet technology. Like ADSL, VDSL operates copper pair but still allows faster transfer speeds.
In addition to obtain these rates need to transfer the data transmission frequencies are much higher than the 1.1 MHz used in conventional ADSL. Four channels are used for transmitting, two for two to download and upload, so it improves signal strength appreciably.
According to my knowledge VDSL is typically installed with asymmetrical, allowing a much higher download speed than upload speed to adapt well to market needs.
52 Mb 12Mb download and upload, clearly much greater than those of conventional ADSL. With these speeds can be offered Internet services, phone calls and digital TV transmission under the same line.
Additionally VDSL can be deployed to customers very close to the telephone but it is not limited to this and that is normally provided from an office located in the street connected by optical fiber plant thus avoiding signal loss and noise that would fail the Using this new technology.
