NTT has developed a prototype chip that could increase communications speeds in data centers and submarine cables. The chip can amplify a 100 Gigahertz (GHz) electrical signal in laboratory conditions, a key step towards 6G. The ultra-compact baseband amplifier IC module is years away from being commercially released, but NTT expects to use the chip in future all-photonics networks. NTT believes that its core optical network, Innovative Optical and Wireless Network (IOWN), will require transmission speeds of more than two terabits per second and a baseband amplifier IC module that can amplify the signal. NTT develops prototype baseband amplifier chip for 2 terabytes per second networks – DCD (datacenterdynamics.com)
