15 Tb/s Unrepeatered Transmission over 409.6 km using Distributed Raman Amplification and ROPA

15 Tb/s (150 × 120 Gb/s) unrepeatered transmission is achieved over 409.6 km (68.2 dB), corresponding to a record capacity-reach product of 6.14 Pb/s-km. We also demonstrate channel growth from 10 to 150 waves within 61 nm amplification bandwidth.
