Abstract
Application-specific integrated circuit (ASIC) is at the core of modern ultra-high-speed transponders employing advanced digital signal processing (DSP) algorithms. Jointly to advanced transmission techniques, such as probabilistic shaping and digital sub-carrier multiplexing, it enables high capacity coherent transmission. In this invited contribution, we present our recent data-rate × distance record with experimental transmission of all real-time 800G channel over 1000 km in full C-band.
