Titel
Nonlinear transmission of 6PolSK-QPSK signals using coded modulation and digital back propagation
Abstract
We experimentally investigate the characteristics of 126-Gb/s coded 6PolSK-QPSK signals in the nonlinear transmission regime and demonstrate that required OSNR improvement is increasing with fiber-launch power due to coded modulation as well as digital back propagation.
