Extremely high-speed digital subscriber line (DSL) connections over short distances.
VDSL represents the most likely future of DSL technology. It offers the highest speed of all the DSL variants, and it uses a fiber-optic connection unlike the other variants, which use the telephone company's local analog loop for their transmissions. VDSL supports downstream speeds ranging from 13Mbps to over 50Mbps, depending on how far the customer is from the phone company's local exchange. The 13Mbps speed is supported over distances as long as 4500 feet, whereas the highest speed is supported only for stretches of 1000 feet or less. Upstream speeds for VDSL are 1.5Mbps and higher. VDSL technology will require the next generation of digital loop carriers - that is, fiber running (almost) to the home.

Very high speed Digital Subscriber Line (see ADSL).
The newest of the DSL technologies, VDSL can offer speeds up to 25 Mbps downstream and 3 Mbps upstream. Similar to SDSL, the gain in speed can be achieved only at short distances. These maximum speeds can be achieved only up to 1,000 feet. Sometimes also called broadband digital subscriber line (BDSL). See DSL, ADSL, HDSL, IDSL, RADSL, SDSL, xDSL.
A next-generation DSL service that will take advantage of sophisticated new modems to greatly accelerate video and data over existing telephone company network infrastructures at speeds of 8 Mbps to 53 Mbps.
VDSL is a developing technology that promises much higher data rates over relatively short distances. It's thought that VDSL may emerge somewhat after ADSL is widely deployed and co-exist with it.
Very high-bit-rate Digital Subscriber Line One of the asymmetric DSL technologies that have different transfer speeds between the upload and download of data. The transfer speed of downstream from an exchange to a user is 13Mbps to 52Mbps while that of upstream from the user to the telephone exchange is 1.5Mbps to 2.0Mbps. As VDSL uses higher frequencies than ADSL, it has less interference with other communications and is able to achieve higher speed data transfer. However, one disadvantage is that it can be used only for relatively short distance of communications.
VDSL (Very high bandwidth DSL) is in the early development phase but promises much higher data rates over relatively short distances (between 51 and 55 Mbit/s over lines up to 1,000 feet or 300 metres in length)
Very high bit rate Digital Subscriber Line - An ultra high-speed type of DSL that can deliver data communication at speeds up to 52 Mbps in close proximity to a central office.
Very High Bit Rate DSL; Customers must be within 4,500 feet of the Central Office. Provides data rates of 13 - 52 mbps downstream and 1.5 - 2 mbps upstream. Available in selected markets only.
very-high-data-rate digital subscriber line. One of four DSL technologies. VDSL delivers 13 to 52 Mbps downstream and 1.5 to 2.3 Mbps upstream over a single twisted copper pair. The operating range of VDSL is limited to 1,000 to 4,500 feet (304.8 to 1,372 meters).
Video (or Very-high bit rate) Digital Subscriber Line, the fastest form of xDSL, it provides asymmetrical full duplex connectivity at 52 Mbps to the subscriber and 16 Mbps from the subscriber, over distances of up to 1.2 Km (0.75 miles) over a single pair. This type of transmission does not support telephony over the same physical pair as do ADSL and RADSL.

Very-high-data-rate Digital Subscriber Line. A technology in the very early stages of definition. Initial VDSL implementation likely will be in asymmetric form, essentially being very high speed variations on the A D S L them.
Very High Bit Rate Digital Subscriber Line. VDSL is a shorter distance, higher speed derivative of the DSL family. It was intended for "the last mile," the costliest link from any service to any final destination. As this last segment is usually dedicated to a single customer, VDSL can be combined with fiber to offer cost-effective, short-distance runs at speeds of up to 52Mbps.
Very High-Speed Digital Subscriber Line. There is not yet an international standard for VDSL so it is not very common.

Very High Speed Digital Subscriber Line (VDSL) transmits data between 1000 and 4500 feet (300 - 1500 meters) up to 50 Mbps through twisted pair copper wire. The rule with VDSL is the shorter the distance, the faster the connection rate. VDSL users enjoy the maximum bandwidth available through normal phone lines.

Very High Bit Rate Digital Subscriber Line. An asymmetric DSL that delivers from 13 to 52 megabits per second downstream bandwidth and 1.5 to 2.3 megabits per second upstream.
A transmission medium that provides a maximum span of about 5,000 feet (1,500 meters) over a single twisted-pair cable. Over this distance, you can get up to a rate of 13Mbps downstream, and if you shorten the distance to 1,000 feet (300 meters), you can get up to 52Mbps downstream, which would be enough capacity to facilitate tomorrow's digital TVs. VDSL gives you 1.5Mbps to 2.3Mbps upstream.
Abbreviation for very high data rate digital subscriber line. A DSL operating at a data rate higher than that of HDSL. See also DSL.
