Sparsely repeated 21.7 Tb/s Net-Rate Transoceanic Transmission with 266 km Ultra-Long Spans Enabled by Low IMI and Low loss Hollow Core Fiber
Rajiv Boddeda, Carina Castineiras Carrero, Haïk Mardoyan +6
We demonstrate 21.7-Tb/s net-rate transmission across 6660-km with 266-km ultra-long spans of HCF. By exploiting a newly designed GTA-ST-HCF, high-power booster, and adaptive chann…
Secret Key Rate Limits in Coexisting Classical-Quantum Optical Links
Lucas Alves Zischler, Amirhossein Ghazisaeidi, Antonio Mecozzi +1
Classical-quantum coexistence enables cost-effective transmission of data and quantum signals over the same fiber-optic channel. Nevertheless, weak quantum-key distribution (QKD) s…
Experimental Characterization and Model Validation of Interference in Classical-QKD Coexistence Transmission
Lucas Alves Zischler, Amirhossein Ghazisaeidi, Carina Castiñeiras Carrero +4
We present an experimental characterization of coexistence-induced interference in QKD transmission arising from SpRS and FWM, validating a comprehensive semi-analytical model for…
First Single-Carrier Transmission at Net Data Rates of 1.6 Tb/s over 9075 km and 2.4 Tb/s over 1210 km Using 300 GBd Dual-Polarization Signals and Probabilistic Constellation Shaping
Haik Mardoyan, Daniel Drayss, Sylvain Almonacil +7
We report long-haul transmissions of single-carrier 300 GBd dual-polarization signals with optical arbitrary waveform generation and measurement. We demonstrate net 1.6 Tb/s over 9…
