Vitesse Introduces Grooming Switches That Enable Lowest Cost, Next-generation Access and Metro Equipment

Vitesse Semiconductor Corp. (NASDAQ: VTSS) today announced two new additions to its industry-leading SONET/SDH Time Slot Interchange (TSI) grooming switch family: the VSC9190, 50 Gbps TSI Switch, and the VSC9191, 100 Gbps TSI Switch. Both devices are targeted at dramatically reducing power and complexity of SONET grooming applications, while simultaneously simplifying and accelerating the system level design process. These devices reduce power requirements by more than 50% over comparable solutions, and, by incorporating automatic protection switching and rate aggregation into a single device, reduce board chip count by a factor of five, dramatically shrinking space requirements and lowering costs.

Scalable, Low Power Design Ideal for Growing Broadband Services While Maintaining Compatibility with Existing Equipment TSIs are a key building block in the $7 billion optical transport systems market. This market grew by 11% in 2004 and is forecasted to grow another 6% in 2005, as reported by the Dell’Oro Group. TSIs perform the necessary function of deskewing, switching, and regenerating SONET/SDH signals at the STS-1/STM-0 level. The VSC9190 and VSC9191 address these complex requirements within Access and Metro equipment such as SONET/SDH Multiservice Switches, Add Drop Multiplexers, Optical Switches, and DWDM Long Haul and Metro equipment.

These scalable TSIs support dual rate 2.5 Gbps or 622 Mbps Input/Output (I/O) speeds, enabling high-speed 2.5 G links or compatibility with existing 622 M equipment, and contributing to lower cost and power requirements. Their fully non-blocking memory-based switch core simplifies system architectures and shortens overall development time with fast, single-step programming that eliminates the need for complex programming algorithms.
