| Popis: | We experimentally demonstrate 506-Gb/s/channel (66.125-Gbaud/channel) eight-channel WDM probabilistically-shaped 16QAM signal coherent transmission using high-bandwidth coherent driver modulator (HB-CDM) over 6000-km fiber with BER under 4.2×10–2. 150% transmission-distance improvement, and 0.216-bit/symbol achievable-information-rate improvement can be attained after probabilistic shaping. |
