“We are pleased to work with leading technology companies such as Teknovus, Emcore, and Anritsu in next-generation PON system development and look forward to expanding ecosystem participation,” added Raymond Fontayne, senior product marketing manager for Vitesse. “The ecosystem’s objectives include proving interoperability with sub-system and component vendors and shortening time-to-market for our network equipment OEM customers.”

FTTx Ecosystem Participants

The initial participants of the FTTx Ecosystem include Vitesse, Teknovus, Emcore, and Anritsu. Each company offers specific PON expertise and is well underway with their contribution to making next-generation wavelength-division multiplexing (WDM) and high-speed PON-based networks a reality.

Vitesse is uniquely positioned to support the migration to new 10G and 40G WDM systems with a complete line of industry leading burst and continuous mode capable 10G laser drivers, transimpedance amplifiers (TIAs), SerDes, and parallel array devices. In addition to this new set of physical medium dependent devices (PMDs) and physical layer transceivers, Vitesse is providing access to advanced technology and demonstration vehicles to ecosystem participants. The Company will also provide feedback to standards bodies focused on PON deployment and adoption.

Teknovus has demonstrated triple-rate (10/100/1000) PON media access controllers (MACs) with support for 10 Gbps, 2.5 Gbps, and 1.25 Gbps downstream data rates as well as 1.25 Gbps and 10 Gbps upstream data rates, enabling carriers to reduce costs by supporting coexistence of 1.25 Gbps, 2.5 Gbps, and 10 Gbps ONUs within a single fiber plant. The physical coding layer and multipoint MAC control layer are central to the system since new FTTx deployments will require reuse and extension of existing PON technologies for the higher layers.

“Working with Vitesse burst mode capable SerDes, Teknovus has been able to validate its Turbo-XPON product line in the industry’s highest performance 10G symmetrical EPON solution. We are already demonstrating this complete system solution to our customers, who are under extreme pressure to field a proven 10G-EPON system as quickly as possible,” said Robin Grindley, director of product line management for Teknovus.

“We are pleased to collaborate with Vitesse in the ecosystem initiative. Our 10G TOSA and ROSA have proven to work flawlessly with Vitesse’s 10G-PON burst mode driver chipset, resulting in the industry’s first 10G-PON market solution,” said Chris Wiggins, director of product line management for Emcore.

Validation of next-generation PON solutions has taken place recently using the latest test gear equipped with the most recent standards requirements. The end-to-end solution was tested with reference platforms using industry standard Anritsu test equipment along with independent confirmation in labs around the world.

“Anritsu is very excited to participate with Vitesse in validating their 10G-PON solutions. Vitesse is developing chipsets with features and performance that exceed industry specifications. To help ensure such high-level performance, the design team relied on our MP1800A Signal Quality Analyzer,” said Wade Hulon, vice president and general manager, Americas Sales Region, Anritsu Company. “The MP1800A, with its multichannel configuration, burst signal BERT capability, auxiliary preamble signals output, and the dedicated PON software, is the perfect solution for controlling burst data and accurately measuring the performance of PON devices. These features have helped Vitesse improve development efficiency and increase yield.”

Vitesse to Present and Demonstrate at Optical Fiber Conference (OFC) in San Diego

Vitesse will showcase a live demonstration of its 10G-EPON symmetric burst mode driver and SerDes solution at the OFC/NFOEC 2009 Expo, March 24-26, 2009, in San Diego, Calif., at the San Diego Convention Center. In addition, Vitesse will chair the “Advanced PON/10G-PON” technical session on Monday, March 23, from 4-6 p.m. during the NFOEC NME session. Please visit Vitesse at Corporate Village Rooms #3044 and #2945 in Hall D.
