159 Tbit/s C+L Band Transmission over 1045 km 3-Mode Graded-Index Few-Mode Fiber

We transmit 3 × 348 × 24.5 Gbaud PDM-16-QAM modulated C+L band channels with a total data-rate of over 159 Tbit/s over 1045 km graded-index three-mode fiber, resulting in a record throughput-distance product of more than 166 Pbit/s × km.
