Google, SubCom, to deploy space-division multiplexing on Dunant submarine cable

Google and submarine network technology supplier SubCom (formerly TE SubCom) say they will apply space-division multiplexing (SDM) technology on the transatlantic Dunant submarine cable SubCom is constructing for Google. The use of SDM, in which transmission power is split across multiple spatial dimensions, will provide a significant, power-efficient capacity boost for Dunant over what a more traditional approach could provide.
