Abstract :
The application of physical-layer network coding (PNC) in optical communications is explored. We propose and demonstrate a practical optical PNC prototype for multicast protection in optical flow, burst, and packet switching networks. Different from conventional theoretical PNC studies, our proposed optical PNC system does not require bit synchronization and can be easily implemented.
