Vitesse Chipset Enables Mass Deployment of Fiber-to-the-Home Systems

LOS ANGELES --(Business Wire)--

Vitesse Semiconductor Corporation (NASDAQ:VTSS), a leading provider of advanced IC solutions for Carrier and Enterprise networks, today introduced an advanced burst-mode architecture for XG-PON1 Fiber-to-the-Home (FTTH) applications. Highly integrated with no external components required, this most advanced edition of Vitesse's PON PROchipset, comprised of the VSC7719 transimpedance amplifier (TIA) and VSC7729 post amplifier, is aimed at XG-PON1 Optical Line Termination (OLT) receivers. The chipset exceeds XG-PON1 standards and enables system vendors and OEMs to easily ramp XG-PON1 systems to volume production.

The expansion of triple-play services and complex FTTH topology among major service providers has led to near-universal acceptance of burst-mode architectures in the central office. As networks move to 10G and faster backbones, individual links from the central office to individual Optical Network Units (ONU) vary in length and become less predictable in performance. Burst-mode receivers increase ONU performance predictability for the consumer, and help optimize for high-bandwidth services such as video on demand (VOD).

The new chipset architecture offers on-chip monitoring of burst power for optimal diagnostics. The set builds on Vitesse's longstanding experience in physical media dependent (PMD) components for passive optical network markets, where the VSC7718/7728 PON PRO set has served the GPON market since 2006, and the earlier VSC7716 TIA (News - Alert) exceeded five million units shipped in recent weeks.

"Few component vendors can offer a settling time capable of meeting GPON or XG-PON1 OLT requirements," said Dr. Simin Cai, president and chief executive officer at Go!Foton Corporation, parent company of Zenko Technologies. "Vitesse has established the expertise to offer proven burst-mode architectures for this market."

With the PON PRO architecture's integrated chip reset and monitor features, system builders can achieve burst-mode PON with no external components required. The set also offers overall performance that shatters conventional limits with APD sensitivity better than -33 dBm (News - Alert) and overload performance better than -6 dBm, as well as a host of features designed to simplify the system interface, such as flexible LVPECL/CML outputs, and a reset through the data interface, which allows the use of standard TO-can headers in design of a BOSA.

"Today's XG-PON1 solutions are mostly discrete, requiring several components, and face space constraints and performance challenges that cannot be supported in volume production. Our new PON PRO architecture solves builds on Vitesse's field-proven technology to solve these challenges and advance Ethernet throughout IP Edge networks," said Aditi Vaghashia, product marketing at Vitesse. "With its high degree of integration and burst-mode capabilities, Vitesse's solution can be used in industry-standard SFP modules, making it easy to support our customers ramping production of their XG-PON1 systems."

Product Packaging and Availability

The VSC7719 is sampling in bare die form, while the VSC7729 will be offered in a 16-pin 3-mm-square QFP-N package - small enough to fit in a SFF or SFP module along with a laser driver. More device information is available at:

Vitesse at OFC/NFOEC in Los Angeles

Vitesse is showcasing its latest IC and software solutions at the OFC/NFOEC Expo, March 6-8, 2012 at the Los Angeles Convention Center in Corporate Village Room #2157. Meetings are by appointment only.

Attendees are also invited to visit Vitesse's FTTX Ecosystem showcase at OFC/NFOEC. In collaboration with other industry leaders including Hisense, Dtech, Zenko, Anritsu (News - Alert), Boardlight, Etri and Oplink, Vitesse has organized a joint demo, located at the Light Brigade FTTX Resource Center in Booth #2747. This event will feature IC's, modules and system level demos for the EPON, GPON, XGPON1 and 40G WDM PON. Learn more about Vitesse's FTTX Ecosystem at
