What do you understand by the VDSL Access Technology? |
|
Answer» VDSL stands for Very High Bit Rate Digital Subscriber Line. It is the technology that has the highest rate of DSL. Operating at speeds up to 52Mbps, VDSL is the next generation of DSL technology with higher throughput and requirements for implementing simpler than ADSL. VDSL began its life being called VADSL, but was renamed VDSL by the ANSI working group T1E1.4. The main reason T1E1.4 decided VDSL on VADSL was that, unlike ADSL, VDSL is both symmetric and asymmetric. VDSL is nearly ten times faster than ADSL and is over thirty times faster than HDSL. The tradeoff for increased speed loop length: VDSL has a shorter reach in the loop. |
