Broadcom has introduced a high-speed coaxial cable solution with access technology for Chinese subscribers in Multi-Dwelling Units (MDUs). The BCM63500 and BCM63333 devices integrate the China HomePlug AV 1.0 (C-HPAV 1.0) standard endorsed by the State Administration of Radio, Film and Television (SARFT), the government agency overseeing broadcasting in the region, to provide operators with an economical solution for broadband services over cable.

The chipset will allow Chinese cable operators to extend broadband services to home subscribers outside of China's major coastal cities, particularly in densely-populated apartment buildings. The integrated C-HPAV 1.0 standard complements Broadcom's existing C-DOCSIS technology by addressing different bandwidth and subscriber density levels than are required for C-DOCSIS deployments.

Broadcom's BCM63500 master chip contains TDMA media access control and physical layer functions, and is located in a fibre termination point in the basement or just outside of an MDU building. The BCM63500 can support up to 64 BCM63333 C-HPAV 1.0 client modems, which are in subscriber's homes.

"Broadcom has delivered a solution that allows cable operators in China to provide services to a previously underserved segment of the MDU market," said Ernie Bahm, Senior Director of Cable Head-end Product Marketing, Broadcom. "The Broadcom C-HPAV 1.0 solution provides our customers with access technology that allows them to take advantage of the large installed base of coax to support multiple MDU markets throughout the region."

"We are pleased with Broadcom's C-HPAV 1.0 solution, which allows us to expand our offerings to a broader footprint of subscribers in our network," said Liang Dong, Technical Director, Henan Cable Network. "Cost-effective and standards-compliant cable broadband modems will allow us to address the growing MDU market in 2015 and beyond without any interoperability issues."

"With new cable modems integrating the C-HPAV 1.0 standard, Kingtype Group now has a more complete portfolio to address the needs of consumers in China," said Mr. Yu Bo, Vice President & CTO, Kingtype Group. "Broadcom's latest chipset design allows us to build new solutions for cable customers in densely populated areas."
