MAY 7, 2007 -- Conexant Systems Inc. (search for Conexant) says it has delivered the world's first family of SoCs for GPON and GE-PON residential gateway applications.
The CX95202 "Xenon-IIIG" GPON and the CX95203 "Xenon-IIIE" GE-PON devices are targeted at optical network units (ONUs) that are used on the client-side of FTTP networks. The devices have a processing capacity of more than 10 Gbits/sec, Conexant says.
"Operators worldwide are planning to use PON technology for next-generation network upgrades to improve their ability to deliver bandwidth-intensive services such as video-on-demand and IPTV," said Akram Atallah, senior vice president and general manager of Conexant's Broadband Access business. "With the launch of our new 'world's first single-chip' PON residential gateway solutions, we now offer our customers a comprehensive portfolio of industry-leading solutions that deliver the performance required for both advanced DSL and next-generation fiber-optic networks."
"Carriers are moving as quickly as they can to establish robust networks that have the speed and capacity required for triple-play service deployments," said Aileen Arcilla, senior research analyst for market research firm IDC. "PON is becoming a viable broadband access technology to be implemented in residential gateways, which are critical to driving mass subscriber growth."
Conexant says the Xenon-III product family provides manufacturers with a flexible option that enables them to address multiple applications in a cost-effective and efficient manner. For example, the Xenon-IIIG and Xenon-IIIE are pin- and software-compatible, enabling product developers to address GPON and GE-PON deployments with the same hardware and software platform. The devices can also be used with Conexant's VDSL2 CO and CPE devices to provide carriers with a cost-effective, end-to-end system approach for fiber-to-the-node applications.
To ensure interoperability, the Xenon-IIIG and Xenon-IIIE SoCs are based on ITU G.984 and IEEE 802.3ah PON industry specifications, respectively. Xenon-IIIE also complies with China Telecom's EPON specification. In addition, Conexant successfully conducted extensive tests with "leading optical line terminal (OLT) end-product manufacturers" to further ensure interoperability on both sides of the connection.
The Xenon-IIIG and Xenon-IIIE include several features that improve performance and lower system costs including:
- Full line-rate performance at 2.4 Gbits/sec downstream and 1.25 Gbits/sec upstream with complete physical layer encryption, security, bridging, and routing required to enable quality of service (QoS) in IP video applications.
- Integrated functionality for four concurrent voice-over-IP channels, three-way calling, and a T.38 fax demodulator.
- Enhanced routing capabilities combined with deep classification and filtering support to enable superior QoS, robust security, and complete management of a customer premises device from the central office.
- Interfaces for home networking technologies including Multimedia over Coax Alliance (MoCA), HomePNA, HomePlug A/V, and Gigabit Ethernet.
The CX95202 Xenon-IIIG and CX95203 Xenon-IIIE SoCs are packaged in an 824-pin plastic ball grid array (PBGA) and priced at $29.50 each in quantities of 10,000. They are currently sampling, with volume production slated for July 2007.
