Optimum carrier to signal power ratio for remote heterodyne DD-OFDM in PONs

Abstract:

The carrier to signal power ratio (CSPR) in a direct-detection optical orthogonal frequency division multiplexing (OFDM) system based on remote heterodyne scheme is optimized in a passive optical network (PON) downlink. A numerical investigation shows that nonlinearities in fiber have the effects of increasing the optimum CSPR and making the system more vulnerable to CSPR changes. © 1989-2012 IEEE.
