Local Dispersion Map Deviations in Metro-Regional Transmission Investigated Using a Dynamically Re-Configurable Re-Circulating Loop

The performance of 40x10.7 Gb/s NRZ-OOK signals is measured in a dynamically reconfigurable recirculating loop experiment with local dispersion map variations up to +/-120 ps/nm and mean residual-dispersion per-span between 10.3-54.0 ps/nm over 28x27dB spans.
