Abstract
A novel orthogonal-frequency-division-multiplexing (OFDM) passive optical network (PON) architecture with centralized light sources and colorless optical network units (ONUs) has been proposed in this paper. The proposed architecture provides bidirectional transmission and employs 2N wavelengths to support 2N ONUs for the downstream and upstream signals. We experimentally and analytically study the performance of downstream 10 Gbit/s OFDM signals and the upstream 2.5 Gbit/s NRZ signals. The study results indicate the system can alleviate the effect of Rayleigh backscattering and crosstalk.
Keywords: orthogonal-frequency-division-multiplexing (OFDM); passive optical network (PON) architecture; bidirectional transmission; Rayleigh backscattering
