Vitesse Forms Next-Generation Fiber-to-the-Home Technology Ecosystem

Technology Leaders Assemble to Advance the Development of Fiber-to-the-Home
(FTTH) and Fiber-to-the-Building (FTTB) Systems
SAN DIEGO--(Business Wire)--
Vitesse Semiconductor Corporation (Pink Sheets: VTSS) continues to increase its
presence in the rapidly expanding Fiber-to-the-Home (FTTH) and
Fiber-to-the-Building (FTTB) markets by establishing a network of leading
technology companies to collectively address and advance development of
next-generation, end-to-end, passive optical networking (PON) systems. The
members of the FTTx Ecosystem will apply their respective architectural
expertise to the deployment of 10G and 40G PON in access networks that deliver
triple play services for high-speed data, voice, and video transmissions. This
collective effort will focus on standards compliance, backward compatibility,
and a smooth upgrade path from existing PON networks.

"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.
