Core Market Segment:

Bandwidth-hungry internet services such as streaming video, gaming, and file-sharing (especially video and high definition video file-sharing) drive service providers to deploy triple-play networks that support these services as well as traditional voice and data services.  The deployment of such triple-play networks place additional burdens on backbone networks, which is necessitating an increase in their transmission speeds.

Cortina Systems^® components support the development of core network deployments that are at the heart of high capacity “triple-play” networks. Cortina delivers a wide suite of products for these deployments that address customers’ performance and density requirements with modern semiconductor technologies and high-speed, analog-digital integration technology.  Specifically Cortina products support:

• Configurable lanes and data rates via Interlaken: an interconnect protocol optimized for high-bandwidth and reliable packet transfers. It builds on the channelization and per channel flow control features of SPI-4.2, while reducing the number of chip I/O pins by using high speed SerDes technology.
• Direct connection to serial optics via SFP and XFP
• Forward Error Correction: various standards based FEC codes including ITU-T G.709, ITU-T G.975.1. Available devices provide from 6dB of net coding gain to more than 10dB.

Target Applications

• OC768 POS Router Line Cards (see Figure 1)
• 40G Framer/Mapper Transport Applications
• High Density 10GE Line Cards
