Anonymous Coward writes "IBM today announced it had developed a prototype chip that could transmit up to 8 terabit/sec of information — equivalent to about 5,000 high-definition video streams — using the power of a single 100-watt lightbulb. The applications for the technology IBM is calling its "green optical link" range from cell phones to supercomputers. The optically-enabled circuit boards, or "Optocards," employ an array of low-loss polymer optical waveguides to conduct light between transmitters and receivers, IBM said. The complete databus constructed with these Optocards incorporates a large number of high-speed channels and closely packs them to achieve huge densities: each waveguide channel is smaller in size than a human hair, IBM said. In addition to the optical data bus, IBM said it developed a parallel optical transceiver module with a higher number of channels and an increased speed of operation: 24 transmitters and 24 receivers that each operate at 12.5 Gb/s.
