Blazing-fast optical chip set could download a movie in a second

Anaheim, Calif. — IBM Corp. is getting closer to solving one of the most vexing challenges in optoelectronics: harnessing the speed of light to transmit data to an electronic interface flawlessly. The company made its initial efforts public recently at the Optical Fiber Communication Conference here, where IBM ?251-186?scientists reported on a prototype optical-transceiver chip set that transfers data at 160 Gbits/second–eight times faster than currently available optical components.
