ARRIS, Xtend Achieve DOCSIS 2.0 using Extended HFC Spectrum

Xtend Networks and ARRIS (announced the ability to offer dedicated high-bandwidth spectrum to commercial customers using standard DOCSIS products. In the tests conducted at ARRIS' laboratories, engineers used off-the-shelf Xtend and ARRIS DOCSIS products under a normal testing environment. Reliable operation and high performance were achieved at 256 QAM modulation downstream and 64 QAM SCDMA modulation upstream.



Xtend's products are based on the ability of advanced application technology and Block Division Multiplexing to increase the available spectrum of the existing cable TV network while providing high-speed symmetrical services to subscribers. Xtend said its technology is compatible with the existing head-end and CPE devices, including DOCSIS, analog and digital TV transmission, and telephony.
