We propose and experimentally demonstrate the first all optical digital network coding between OOK-NRZ Subcarrier Modulated (SCM) signals for Radio over Fiber (RoF) networks using a Semiconductor Optical Amplifier-Mach Zehnder Interferometer (SOA-MZI) as an XOR encoder. Successful encoding and decoding is demonstrated for 1 Gb/s data on a 10 GHz sub-carrier for synchronous and asynchronous NRZ data.
