"Intel has delayed shipment of a component module required for its silicon photonics technology, which uses pulses of light to move data between servers at extremely high speed.
“The original batch of modules, which was supposed to ship at the beginning of the year, failed to meet Intel specifications and quality requirements, Intel spokesman Mark Miller said. Those parts will now be used as samples for testing.”
