ONU, OLT SoC Solutions Go 10G
Fiber-to-the-home semi-conductor provider PMC-Sierra Inc. is marketing an end-to-end symmetric 10G-EPON fiber-access System-on-Chip (SoC) solution.
The PAS9000 Optical Networking Unit (ONU) and the PAS8000 Optical Line Terminal (OLT) SoCs are the industry’s first to support 10Gb/s downstream and 10Gb/s upstream access connectivity, the company says. “This performance and feature integration enables carriers to provide advanced triple-play video on demand, high-speed Internet access and Voice-over-IP services to residential and business customers,” PMC adds. “Transitioning from EPON to 10G-EPON allows carriers to connect up to 10 times more subscribers per Optical Distribution Network (ODN), reducing opex and capex per subscriber.”
PMC’s 10G-EPON solutions reportedly are interoperable with deployed EPON equipment, allowing carriers to upgrade their networks gradually and to deploy 10G-EPON ONUs alongside EPON ONUs. The new units include integrated synchronization functions to enable backhauling of mobile networks over 10G-EPON, “eliminating the need for external circuitry,” company literature says. Integrated power-saving modes help reduce ONU power consumption by more than 50 percent, enabling energy-efficient networks.
“Carriers continue to seek ways to meet the demand for enhanced triple-play services and increased bandwidth, and 10G-EPON provides the answer with high reliability and low operational expenses,” comments Ofer Bar-Or, vice president/general manager at PMC’s FTTH division.
The two recently released devices include a 10G-EPON MAC, SERDES, an embedded controller and a GigaPASS bridge for advanced classification, queuing and filtering. An integrated programmable networking engine provides Quality of Service (QoS) that complies with China Telecom specification version 3.0, including IPv6 protocol support. They also include mobile-backhaul-over-EPON support with integrated Synchronous Ethernet and Time of Day delivery as well as wire-speed throughput at all packet sizes, queuing, filtering and advanced QoS, and Ethernet connection to an external processor.
