According to LightReading, Google is providing a bandwidth breakthrough for its Dunant (Dunan) cable, and it is expected that Google will first implement space division multiplexing (SDM) technology in the cable network. The 6,400-kilometre cable linking the United States and France is entirely privately owned by Google and is expected to be operational in the third quarter of 2020 at a transmission speed of 250 Tbit/s. Google revealed in its Google Cloud blog that Dunant will become the first 12-fiber cable with SDM design, instead of six or eight pairs of traditional cable, and will also introduce power-optimized repeater design. Google is working with SubCom, a cable network builder and technology developer, to implement the technology. The Dunant cable will connect Virginia and Northern Spain at a transmission rate of 250 Tbit/...
