Cortina unveils next-gen optical transport platform

JUNE 2, 2009 -- The CS600x OTN processor platform aggregates and transports data, voice, and video signals simultaneously over 10G or 40G networks.

JUNE 2, 2009 -- Cortina Systems Inc. (search Lightwave for Cortina), a supplier of intelligent communication systems, has releases its next-generation optical transport processor platform. The first product family in this platform, the Cortina Systems CS600x, is designed for use in core, optical, and metro Ethernet markets spanning 10 to 100 gigabits.

The CS600x permits efficient multiplexing and transparent transport of a broad spectrum of 10G class clients including Ethernet, SONET/SDH, and storage over high-speed optical transport networks, says the company.

"Demand for bandwidth-intensive applications such as video-on-demand, music downloads, and telepresence is growing, and network delivery of larger file formats like HD video continues to gain in popularity," says Arun Zarabi, director, Infrastructure Business Unit at Cortina. "Telecom equipment makers are looking for solutions that allow them to deliver these bandwidth-intensive experiences to consumers while keeping their power usage and costs in check."

Developed through close collaboration with systems and service providers, Cortina says its highly integrated common platform is able to aggregate multiple service types such as Ethernet, storage, and SONET/SDH over metro, long-haul, and submarine networks.

"We expect 40G port deployments to double year-over-year and account for nearly 10% of all optical port revenue in 2009," notes Andrew Schmitt, directing analyst, optical at Infonetics Research (search Lightwave for Infonetics). "OTN multiplexing is the critical technology that allows carriers to combine legacy traffic alongside new data services like 10GbE, and the 10G to 40G muxponder is the high-volume application for near-term 40G deployment. The Cortina CS600x is designed to address this application while also providing a solution for the high- density 10G designs which represent the majority of volume."

Features of the platform allow for denser and more flexible line cards for metro and long-haul DWDM applications, Ethernet switch and router platforms, and submarine ultralong-haul systems. Key features include aggregation of four fully independent synchronous or asynchronous 10Gs tributaries to a 40G signal; super forward-error correction ("Super FEC"); transport, mapping, and performance monitoring; and networking support for various client signals.

The CS6001 transport processor, the first member of the CS600x family, features two 17-lane or 16-lane 40G-class interfaces (SFI-5.1 or 16-lane SFI-4.2), eight 4-lane 10G-class interfaces (XAUI or SFI-4.2), and four XFI serial 10G-class interfaces. Additionally, each SFI-5.1 interface can be down-clocked to operate as a 16-bit SFI-4.1 compliant interface. The CS6001 can handle full duplex processing of either a single 40G signal or up to four independent 10G signals. The receiver and transmit ports can be configured independently to monitor (and optionally terminate) OTU3/OC-768, 40GE, and OTU2/OC-192/10 GbE/FC-1200/FC-800 signals.

The device family is offered as five different options that are tailored to various 40G or 10G applications. It is built with 65-nm technology; Cortina is currently shipping samples.

The CS600x will be generally available in July 2009.
