Infinera Makes 1Tbit/s Claim (reader comment included)

WASHINGTON -- With worldwide Internet data traffic increasing by 50 percent each year, telecommunications companies that handle this digital torrent must be able to economically expand the capacities of their networks while also adapting to new, more-efficient data-handling technologies. Over the last decade, a development team at Infinera Corp. in Sunnyvale, Calif. has pioneered the design and manufacture of photonic integrated circuits (PICs) aimed at meeting that need. This technology has enabled the team to achieve a record one trillion bits per second (1 Terabit/s) speed on a single integrated indium phosphide chip. The findings will be presented at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC) taking place March 6 -- 10 at the Los Angeles Convention Center.
"Traditional transponder-based system architectures are inflexible and costly and time-consuming to upgrade," said Dr. Radhakrishnan Nagarajan, research fellow at Infinera and a senior member of Infinera's PIC development team. "Our PIC approach enables us to make optical networks more powerful, flexible and reliable than ever before using equipment that is significantly smaller, less expensive and uses much less energy."

I think it has been well known that current 10G system has always had a TX and RX PIC. I not sure if they plan on incorporating both within one PIC. However if they are that would certainly an order of magnitude more difficult then their present architecture. To answer your question regarding could another company duplicate the PIC. Yes, if they hired all the INFN Software, Hardware and PIC development people and have 3-5 year window to accomplish it not mention the $300M+ to fund it. So the real answer is NO. |
