Intel Ready to Ship Silicon Photonics Modules This Year
The technology, in development for 16 years, will help address the growing demand for better network speed and bandwidth between data centers.Intel officials are ready to bring silicon photonics—in development for 16 years—to the market. At the Intel Developer Forum (IDF) this week, Diane Bryant, executive vice president and general manager of the company's Data Center Group, announced that the chip maker has begun shipping silicon photonics modules, the first products in an expected portfolio that officials have said will help meet the growing demand from cloud service providers for more network bandwidth, better scalability and faster connectivity. Silicon photonics refers to the use of pulses of light rather than electrical signals over copper wires to move large amounts of data at high speeds and over long distances. Intel's first two products, the 100G PSM4 (Parallel Single Mode fiber 4-lane) and 100G CWDM4 (Coarse Wavelength Division Multiplexing 4-lane), will target switch-to-switch optical interconnects in data centers and will be available later this year, with adoption ramping next year. The first silicon photonics-based components will enable the transfer of data at 100 gigabits per second over distances of 2km or more, and will come in a pluggable model and an embedded form factor. Silicon photonics not only will use light to offer faster connectivity, but Intel's technology also uses silicon lithography to more precisely align the laser, all of which will lead to greater performance, better efficiency and lower costs, officials said.
The technology will enable organizations to move beyond the scaling and distance limitations of copper wire for transferring data between data centers and within systems, all at lower cost and greater efficiency, Bryant said during her keynote address at the show.
