Abstract:
We have achieved polarization-interleaved 4-level/7-level coding PAM transmission using 1-Sps pre-compensation for chromatic dispersion with a narrow-electrical-bandwidth limitation based on numerical simulations. We experimentally confirm the scheme feasibility using 112-Gb/s signal and 20-GHz bandwidth limitation in a conventional direct-detection system.
