Abstract:
We demonstrate a C-band 50 Gbaud 16-QAM WDM transmission under bidirectionally pumped distributed Raman amplification, where the forward pumps are only semiconductor incoherent sources. Compared with the EDFA-only amplification, the transmission distance is extended from 1,800 km to 3,200 km.
