VDSL Standards

VDSL Standards
Among home users, there are currently two broadband technologies that dominate the market: cable modems and ADSL (asymmetrical digital subscriber line). While both of these choices offer connection speeds far better than a 56K modem, they are unable to support services such as digital television or Video-on-Demand. The next generation of broadband, though, is thought to be on the horizon in the form of VDSL, or very high bit-rate DSL.
To many observers, it has become clear that telephone companies will be using existing twisted-pair loops in the next generation of broadband access. Hybrid Fiber Coax (HFC) simply does not work if asked to carry telephony, interactive video, and high-speed data simultaneously. And Fiber all the way to the home (FTTH) is too expensive to be considered seriously. However, what is now–or will be soon–economically viable is Fiber to the neighborhood (FTTN), leading to Optical Network Units (ONUs). It is this technology that makes VDSL possible.
VDSL Standards: The Next Generation of Broadband
VDSL, like ADSL, has limitations depending on proximity to the source signal. In fact, VDSL requires that the maximum distance be significantly closer than does ADSL. This, however, is where FTTN, leading to local ONUs, becomes a factor. The local ONU will enable the distance from the signal to the end user to be within the accepted range.
VDSL service is beginning to be rolled out for residential service in select parts of the United States. There are, however, business applications that are currently available. We have the expertise, the know-how, and the experience to help your business use this emerging next-generation technology today. We have all the VDSL equipment you need to get started.
