NOVEMBER 19, 2008 -- Teknovus (search for Teknovus), provider of GE-PON chipsets for the deployment of triple-play services in broadband access networks, yesterday announced that three major Chinese communications equipment vendors have designed 10G EPON systems based on Teknovus' 10G EPON technology. The vendors'10G EPON systems were demonstrated at major tradeshows in October, including the Beijing PTT Show in China.
"China is positioned to exceed 6 million EPON-based FTTx subscribers this year with plans for up to 18 million new subscribers in 2009," reports Dr. Lynn Hutcheson, vice president, Communications Components at Ovum. "For future upgrades and higher capacity access networks, the Chinese carriers are arduously evaluating 10G EPON and the vendors are aggressively developing product. This looks like an excellent fit for high-density environments," he notes.
Teknovus says its 10G EPON guarantees quality of service for voice, data, and video services to hundreds of subscribers simultaneously, including hundreds of channels of HDTV along with heavy data traffic, such as YouTube videos.
Now generally available, Teknovus' 10G EPON evaluation board system (EVB) is compliant with the latest draft of the IEEE 802.3av 10G EPON standard. The EVB contains both OLT (central office) and ONU (customer premises) devices along with comprehensive development tools. A reference design is also available, which has already been used by system vendors to develop customized implementations of the OLT line card compatible with their existing chassis, as demonstrated at the Beijing PTT Show.
In addition to the IEEE 802.3av feature set, the 10G EPON EVB system supports triple-lambda WDM downstream operation at 1.25, 2.5, and 10G simultaneously, explains the company. This allows system vendors to do extensive testing of co-existence between 10G and currently deployed networks, which is of critical importance for carriers' network upgrade plans. The 10G EVB system also supports the same value-added features that exist in Teknovus' current-generation chips, says the company, including support for M-LLID; flexible Hardware-based DBA to ensure strict and accurate SLA enforcement; guaranteed service-level isolation; and predictable fairness under heavy traffic loads.
"Teknovus is working with several optical transceiver vendors to enable a cost-effective 10G solution," confirms Robin Grindley, director of product marketing for 10G products at Teknovus. "Our combined solution will help realize Chinese carriers' vision to support the medium-term per subscriber bandwidth requirements of 20 Mbits/sec for up to 512 users for 10G FTTB deployments for triple-play services, while future-proofing subscriber bandwidth growth needs of up to 50 Mbits/sec over the next five years," Grindley adds.
Teknovus' 10G EPON is the next generation of EPON and supports seamless coexistence with 1G and 2.5G EPON, enabling service providers to meet different subscriber requirements on one PON. Teknovus says it is demonstrating its 10G EPON EVB systems over the next several months in Asia, including China, Japan, Korea, Malaysia, Taiwan, and Hong Kong.
