Optical networks and ID tags

Senior engineer Kevin Chang (below) is part of a team at Fujitsu Network Communications that developed a novel program for optimising optical networks.

Today's popular wavelength-division multiplexing nets break communications channels into various lambdas that get switched back and forth, sometimes creating unusable spaces. Chang and team developed a program that finds and eliminates the unused spaces in a way that's similar to defragmenting an over-used disc drive.

Other researchers showed a way of using patterns of reflected LED light as an ID tag that can be picked up by a smartphone's camera. Once detected the tag calls up cloud data that can be presented as, for example, an augmented-reality animation on the portable device. Fujitsu sees the technology being used in many locales including retail shops and museums.
