Symmetric end-to-end 10G-EPON SoCs
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. The company’s 10G-EPON solutions are interoperable with deployed EPON equipment, allowing carriers to gradually upgrade their networks and deploy 10G-EPON ONUs alongside EPON ONUs.
The company’s ONU devices claim the industry’s most advanced integration to reduce system cost and power. Integrated synchronization functions enable backhauling of mobile networks over 10G-EPON, eliminating the need for external circuitry. Integrated power-saving modes reduce ONU power consumption by more than 50 percent, enabling energy-efficient networks.
The 10G-EPON solution complies with IEEE 802.3av and China carrier specifications and is targeted at Fibre-To-The-Home (FTTH), Fibre-To-The-Curb (FTTC) and Fibre-To-The-Building (FTTB) applications. All devices feature the company’s field-proven GigaPASS architecture that achieves up to 10 gigabit data rates, and is already deployed in more than 20 million PON devices worldwide.
“10G-EPON provides one of the most cost-effective methods for service providers to deliver enough bandwidth across their access networks to support ever-increasing consumer demand for bandwidth-intensive devices like smart phones and tablets,” said Jeff Heynen, directing analyst for broadband access and video at Infonetics Research. “Features like EPON and 10G-EPON interoperability and the availability of symmetric and asymmetric modes make EPON the most flexible and scalable fibre access option.”
The PAS9000 family includes the PAS9301 asymmetric ONU and the PAS9401 asymmetric and symmetric ONU. The devices include a 10G-EPON MAC, SERDES, powerful embedded controller and GigaPASS bridge for advanced classification, queuing and filtering. An integrated programmable networking engine provides enhanced Quality of Service (QoS) that complies with China Telecom specification version 3.0, including IPv6 protocol support. The company’s scalable User Network Interface is configurable to up to four GbE interfaces, up to four 2.5 Gb/s interfaces, or to a 10 Gb/s interface for Single Family Unit or Multiple Dwelling Unit applications.
The devices 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. The solutions reuse the company’s widely deployed EPON software packages, including the ONU software package, which is common for EPON and 10G-EPON ONUs, to preserve OEM investment and reduce time-to-market. PMC software supports low-footprint OS and Linux, featuring a 10G EPON protocol stack and networking drivers, IEEE 802.3av OAM protocol with operator-specific stacks and integrated peripheral drivers.
The comapny’s previously announced PAS8000 OLT devices integrate the most advanced fibre access capabilities on the market. An integrated traffic manager enables carriers to deliver new services to more subscribers. A complete, always-on toolkit for optical network and ONU inspection, consisting of an Optical Time Domain Reflectometer (OTDR) and Upstream Signal Analyzer, enables carriers to test outdoor fibre-optics lines while in service, preserving network uptime and providing significant OPEX and CAPEX savings.
