JAKE SALTZMAN, NEWS EDITOR [email protected]A University College London (UCL) and Microsoft-led research team has introduced a new technique for simultaneously synchronizing the clocks of thousands of computers, in less than one nanosecond. The technique, which the team is calling “clock phase caching,” paves the way for the use of all-optical networks by enabling optical switching to take place in data centers. A heavy and increasing volume of server-to-server traffic currently places high demand on data centers, the extensive networks of connected servers that empower users to perform a wide range of functions...Read full articleRelated content from Photonics MediaArticlesQuasicrystals Create Light Vortices to Transmit More Data with Fiber OpticsAs the demand for data storage grows, better ways to encode large amounts of data for rapid transmission are required.
