Innovative VDSL vectoring solution from Alcatel
VoIP appliances industry giant Alcatel-Lucent has announced the general availability of VDSL2 Vectoring. Since now services providers acquire the possibility massively boost the data processing speed and capacity of existing copper access networks to ensure customers broadband speeds of 100 megabits per second (Mbps) and more.
As Alcatel-Lucent boasts, it will ensure them, “get to fast, faster.” Current global trends in industry of telecommunications are that facilities-based service providers are continuously speeding up the amount of fiber in their infrastructure. Nevertheless, the indicators show that 2/3 of the world’s broadband subscribers are connected by means of DSL. In average 1.25 billion households are connected to a copper wire, and in total 40 million VDSL2 lines have been deployed within last four years. The general challenge for service providers has been — keeping in mind growing demands for higher broadband speeds and growing market pressures from cable TV and now 4G LTE, as high-speed broadband access alternatives — how to quickly and cost-effectively provide customers the speeds and feeds they want. Carriers have done massive improvements in order to deploy fiber as deep as possible into their outside arrays. VDSL2 Vectoring makes it possible for SPs to extend the life of their last mile copper plant, thus soothing up the pains and cost for huge and expensive deployments of fiber. It also makes it possible for them to improve the quality of their broadband services while reaching more subscribers more quickly than ever. The message for SPs is simple and straightforward from asset management and competitive perspectives. Leveraging copper plant to boost DSL speeds has three key benefits as follows: Fast broadband, associated with 100M per second and beyond. Faster time-to-market: Rapid build-out, allowing service providers to reach more users with more bandwidth now and reach national broadband targets faster. Much more rapid turnover of the incurred investment. VDSL2 Vectoring is similar in concept to the technology used in noise-cancelling headphones. First, it measures the crosstalk, or interference, among the lines in a DSL bundle. Afterwards, it creates an opposite phased signal for every line to remove the crosstalk noise on the line. Having removed the crosstalk noise, each VDSL2 line in a bundle can work at peak speeds. This translates into for the SP is a standards-based consistent measurable increase in the amount of available bandwidth per line with all lines performing more predictably at a higher level. In other words, along with better performance it provides an improvement for facilities and services planning. ALU has been a leader in vectoring including: serving as editor of ITU-T Vectoring standard (G.993.5); developing the first prototype vectoring line-card in 2Q 2010; and is now first to commercial availability with its solution. With consumer needs expected to grow from 50 Mb/s to the home by 2015 to 90 Mb/s by 2020 (a 15% annual growth rate), the European Commission’s Digital Agenda calling for 30 Mb/s for all homes by 2020 with 100 Mb/s for half of households and the “Connecting America” initiative seeking 100Mb/s to 100M households by 2020, VDSL2 Vectoring not only meets but exceeds those requirements along with providing an answer to competitors. The proof as the old saying goes, “is in the pudding.” Increasing speeds on existing copper is cost-effective in the local loop and also takes less time than a nation-wide FTTH roll-out. In fact, it has been estimated With VDSL2 Vectoring, you can deliver higher speeds at about 1/3 the cost of deploying fiber. This means operators have a double edged sword to wield to be first to market, fast to market and fast in their markets in terms of generating new revenue, quickly.
