Abstract
We investigate off-the-shelf semiconductor optical amplifiers for long-haul transmission and find error-free performance after 2400 km of 7×WDM, polarization division multiplexed 32-Gbaud probabilistically-constellation-shaped 16 and 64-QAM rate-adaptive signal in a recirculating loop system.
