ZTE Corporation ("ZTE") has set a new world record in 400G high-speed transmission.
ZTE used its patent technology to achieve 40 DWDM (dense wavelength division multiplexing) channels of 400Gb/s single-carrier polarization division multiplexing QPSK (PDM-QPSK) signals to successfully transmit 2800 km in standard single-mode fiber, smashing the world record of 1200 km transmission distance of single-carrier 400G.
