VDSL

verkhvysokoskorostny digital subscriber line. Abbreviation of Very High Bit-Rate Digital Subscriber Line. Is the fastest of all xDSL technology. Provides data transfer rate of the "descending" flow within 13 — 52 MB/sec., and data transfer rate of the "ascending" flow within 1.5 — 2.3 MB/sec. (on one couple of telephone wires). This technology can become a cost-efficient alternative to the optical fiber cable. But it is necessary to consider that the data transmission distance for it makes 300 — 1300 meters.
