In automatically restorable optical networks, the control plane has to detect a failure and send traffic through recovery paths. A successful restoration is guaranteed if an appropriate number of spare resources is available in the network. Usually a quality of transmission (QoT) estimator helps estimate the number of opto-electronic devices to guarantee transparent connection, within a given confidence...
This paper presents the design architecture of a new optical switching device named Protection Switching Device (PSD) for providing protection and restoration against fiber failures/faults in the distribution region of passive optical network (PON). The developed PSD prototypes are employed at the customer end, just before the optical network units (ONUs) to ensure the data flow continuously due to...
