  "IBM has adopted optical interfaces for its latest POWER7-based
   high-end computer system. Gazettabyte spoke to IBM Fellow,
   Ed Seminaro, about high-performance computing and the need for
   optics to address bandwidth and latency requirements."
.....
  "Using optical engines, each node - a specialised computing card -
   has a total bandwidth of 224, 120 Gigabit-per-second (12x10Gbps)
   VCSEL-based transmitters and 224, 120Gbps receivers. The interfaces
   can interconnect up to 2,048 nodes, over half a million POWER7
   cores, with a maximum network diameter of only three link hops.

   IBM claims that with the development of the Power 775, it has
   demonstrated the superiority of optics over copper for high-end
   computing designs."
