Abstract :
We demonstrate the generation and detection of single-carrier electronic time division multiplexing 400 GE signal based on 120-GBd PDM PAM-4 signal. The signal performance is significantly improved by using our novel pre-equalization scheme. A line rate of 480-Gb/s is achieved, which enables 20% forward-error correction overhead to keep the record 400-Gb/s net information rate.
