A novel wavelength reused bidirectional RoF-WDM-PON architecture to mitigate reflection and Rayleigh backscattered noise in multi-Gb/s m-QAM OFDM SSB upstream and downstream transmission over a single fiber
The advantage of the proposed architecture is that the reflections of RB-RE of carrier and data signals are eliminated. The effect of the higher- order harmonics and their RB-RE in bidirectional transmission is considered in the analysis.
