Real-time 33.6 Tb/s (42 × 800 Gb/s) Unrepeatered Transmission over 302 km Using ROPA System

This paper demonstrates a record unrepeatered transmission with the capacity of 33.6 Tb/s (42 × 800 Gb/s) over 302.7 km (47.52 dB) with a single fiber configuration, using forward Raman pump, backward ROPA, and ultra-low loss & large effective area fiber.
