Broadcom rolls C-DOCSIS chipset for Chinese operators

Broadcom Corp. has unleashed a C-DOCSIS SoC for Chinese operators to scale service deployments for more cost-efficient, competitive offerings. The device offers Chinese operators with tailored offerings for their growing customer bases that scale effectively for smaller multiple-dwelling units (MDUs) with 50 to 200 users, stated the firm.

Driven by the market evolution towards interactive TV, Internet and telecommunications services in China, also known as "triple-play" services, Chinese cable operators require standards-based solutions for economical and final-100m access technologies. Broadcom said its 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 fibre 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.

Broadcom's C-DOCSIS CMC chipset is optimised for compatibility with Broadcom's cable modem, set-top box, and 10G EPON Optical Line Terminal (OLT) and GPON products, to deliver advantages to cable operators distributing their services over coaxial cable across in-building networks. The BCM3227, when coupled with Broadcom's cable modem chips including the BCM3383, BCM3384, BCM33843 and BCM3385, supports advanced modes in the C-DOCSIS standard to boost downstream speeds by 25 per cent to 1Gb/s, and to boost upstream speeds by 33 per cent to 160Mb/s. When integrated into a coax media converter, the BCM3227 transitions DOCSIS-based customer premise equipment from a multi-dwelling unit (MDU) coaxial network to a digital fibre network. As a result, operators can take advantage of DOCSIS benefits while providing an economical architecture to implement triple-play services to MDUs in China.

The Broadcom BCM3227 is currently sampling.
