Abstract
This study examined the performance of 110 Gb/s all-optical domain orthogonal frequency division multiplexing (AO-OFDM) signal transmission systems using optical multi-carrier generation and optical 2-subcarrier modulation under the effects of chromatic dispersion and fiber nonlinearity. The numerical simulation results showed that the performance degradation of AO-OFDM signals lies in the inter-carrier interference between the subcarrier signals generated from the fiber nonlinearities. The numerical simulation showed that the calculated BER of the AO-OFDM channels has some power penalties at 10 -9 BER for the fiber chromatic dispersion effect. The calculated receiver sensitivity at 10-9 BER showed additional degradation at the central subcarrier channel by applying a fiber launching power of 12 dBm after transmission over a 100 km standard single-mode fiber (SMF) link. The simulation results are expected to be useful for multi-service systems employing AO-OFDM technology in the future long-reach passive optical network (PON) applications.
