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...

We experimentally confirm the optimum combination of modulator delay and filter bandwidth to maximize the dispersion tolerance of partial DPSK.
Enhancing Crosstalk Tolerance in Single-Feeder Reflective PONs by Using 8B10B Coding and Ad-Hoc Electrical Filtering
Crosstalk Tolerance Single-Feeder Reflective PONs 8B10B Coding Ad-Hoc Electrical Filtering
2015/7/16
Reflective PONs performance are physically limited by crosstalk from reflections and back-scattering.We demonstrate a seamless approach based on 8B10B coding and proper high-pass filtering allowing to...
Impact of nonlinear impairments on the tolerance to PMD of 100Gb/s PDM-QPSK data processed in a coherent receiver
nonlinear impairments tolerance PMD PDM-QPSK coherent receiver
2015/8/3
The tolerance to PMD of 100Gb/s PDM-QPSK systems is investigated in linear and nonlinear regime.Experimental results show that nonlinear effects decrease the robustness of the system against PMD.
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...
