IBM optics hit 160 Gbits/s

Optical chip-to-chip links on a printed circuit board are not yet ready for prime time, but IBM researchers are already cranking up the speed limits. IBM's T. J. Watson Research Center will present a paper on March 29 at the 2007 Optical Fiber Conference in Anaheim of a "160-Gb/s, 16-Channel Full-Duplex, Single-Chip CMOS Optical Transceiver,” the company announced today. It claims the prototype device is eight times faster than today's transceivers although it may not be ready for commercial use for three to five years.

Few details of the paper are available yet. But IBM did say the chip set includes indium phosphide and gallium arsenide optical components as well as a CMOS transceiver in a 3.25 by 5.25 millimeter package. A Reuters report now on EE Times said the device measures 17 square millimeters and dissipates 2.5W.

This chipset is designed to enable low cost optics by attaching to an optical printed circuit board employing densely spaced polymer waveguide channels, IBM said. DARPA helped fund the research as part of its Chip to Chip Optical Interconnect (C2OI) program.

160Gb/s is amazing, make me thinking what "160-Gb/s, 16-Channel Full-Duplex, Single-Chip CMOS Optical Transceiver” means. 160G per channel or 10Gb/s for each channel (turns out 160Gb/s for 16 channels)? I am waiting for more detailed info from them.
