iSMART's high-speed DSM L3 range and speed-multiplying technology

ECI Telecom and Actelis Networks the founding members of the iSMART Consortium have completed the tests on the consortium's Dynamic Spectrum Management Level 3 (DSM L3) technology. Through this technology crosstalk interference between twisted copper pairs can be eliminated and provides a high-speed, high-value VDSL2 services, effectively multiplying the coverage area of VDSL2 equipment by a factor of 10 in some cases.

DSL services can be provided efficiently over long distances in existing copper access loops. Using the existing copper wire, VDSL2 technology enables to offer 100Mb/s.

"For years, the high cost of FTTH implementation has hindered widespread adoption of GPON or point-to-point fiber access networks, making it extremely expensive - even for leading operators - to deliver advanced service bundles increasingly demanded by customers. But iSMART's successful leveraging of DSM L3 technology makes VDSL a far more viable and cost effective choice for operators who are still not ready to migrate their access networks to full-fiber end-to-end FTTH systems," said Erik M. Keith, Principal Analyst for Broadband Infrastructure at Current Analysis.

iSMART says, according to the 2Q09 'Broadband Aggregation Hardware and Subscribers' report from Infonetics, between 2009 and 2013 the number of worldwide VDSL subscribers will increase by 45%. Although the growth of PON FTTH subscribers will continue to grow, VDSL will unquestionably play an important role in the future strategy of high-speed broadband providers through the next decade.

"Today, we have truly revolutionized DSL with the world's first demonstration of the iSMART Consortium's DSM L3 technology. We are addressing operators' needs for increased competitiveness and cost-effectiveness in today's challenging marketplace," said Ido Shargil, chairman of the iSMART Consortium and head of system engineering at ECI Telecom.

"DSM L3 technology virtually eliminates the most significant source of crosstalk in VDSL2-based networks, enabling cost-effective wide-scale deployment of high-speed, high-value services over existing copper pairs," said Ioannis Kanellakopoulos, PhD, chief technology officer at Actelis Networks. "Actelis is delighted to leverage our extensive crosstalk cancellation experience in the iSMART Consortium, where the technology we and our consortium partners are developing is expected to result in products that deliver an unprecedented combination of rate, reach, and reliability over copper."
