Broadcom expands C-DOCSIS product line for Chinese operators

HANGZOU, CHINA: Broadcom Corp. has announced a new C-DOCSIS system-on-a-chip (SoC) for Chinese operators to scale service deployments for more cost-efficient, competitive offerings.

The new device expands on Broadcom's flagship C-DOCSIS silicon, the BCM3218, to provide Chinese operators with tailored offerings for their growing customer bases that scale effectively for smaller multiple-dwelling units (MDUs) with 50 to 200 users.

Driven by the market evolution towards interactive television, Internet and telecommunications services in China, also known as "triple-play" services, Chinese cable operators today require standards-based solutions for economical and final-100-meter access technologies.

Broadcom's standards-based C-DOCSIS technology provides the higher bandwidth packet transport needed for such Internet connectivity, video and voice service by leveraging operators' existing coaxial infrastructure.

C-DOCSIS works by using Ethernet Passive Optical Networking (EPON), Gigabit Passive Optical Networking (GPON) or point-to-point digital fiber methods to offer interoperability between system providers and robust Quality of Service (QoS) to ensure packet delivery during periods of network congestion.

The technology is certified by SARFT, the Chinese State Administration of Radio, Film and Television agency that oversees broadcasting in the region, and has been field-tested and deployed by top Chinese operators and OEMs, including Huawei, LanCable, Sumavision and ZTE.
