Nonlinear Tolerance of 112-Gb/s DP-QPSK in a Live Field Upgrade Trial over a 848km 10G DWDM Link
Live Field Upgrade 10G DWDM Link Nonlinear Tolerance DP-QPSK
2015/5/18
An in-service field trial with coherently detected DP-QPSK at 112 Gb/s was performed over a Telefónica live link of 848km, testing long term stability and determining noise margin and optimum launch p...
Improved Nonlinear Tolerance of 112-Gb/s PDM-OFDM in Dispersion-Uncompensated Transmission with Efficient Channel Estimation
Nonlinear Tolerance PDM-OFDM Dispersion-Uncompensated Transmission Efficient Channel Estimation
2015/7/30
We show numerically that the nonlinear tolerance of a 112-Gb/s PDM-OFDM signal, coherently received with a robust and efficient channel estimation method, is substantially improved by fiber dispersion...
