Transmission over 1050-km Few-Mode Fiber based on a Bidirectional Distributed Raman Amplification
15 April 2016
We characterize the distributed Raman amplification in a 70 km 3-spatial-mode few-mode fiber with different pump configurations and demonstrate bidirectional pumped Raman amplification and 1050 km combined wavelength-division and spatial-division multiplexed transmission in the same fiber with a zero-net-gain fiber span.
