POWER EFFICIENT TRANSMISSION OF 320 GB/S OVER 17545 KM, AND 560 Gb/s OVER 6050 KM USING 98 GBD QPSK AND 64QAM AND CMOS TECHNOLOGY
22 September 2019
We demonstrate power efficient 320 Gb/s transmission over 17,545 km, and 560 Gb/s over 6,050 km, using 98 GBd PDM-QPSK/64QAM and CMOS DAC technology. We apply digital and optical pre-emphasis. At the receiver side the standard digital signal processing is employed. We avoid nonlinear compensation.
