The power divergence and the resulting transmission penalty due to wavelength rerouting is measured in long-haul transmission for different power adjustment steps in an applied constant gain circulating loop experiment.
OSNR degradation at an optical performance monitoring site within a network is correlated with end terminal performance for fault localization. Sensitivity to 25 dB OSNR is shown to be sufficient for identifying faults that impact the end terminal.
The first experimental determination of the limitations of monitoring OSNR using the optical spectrum is provided for 10 and 40 Gb/s networks with high spectral efficiency and optical add-drop multiplexers.
