A comparison of energy consumption of an integrated optical-wireless network with different wireless signal transport schemes is investigated. The results indicate that digitized RF/IF-over-fiber schemes are the most energy-efficient for integrated optical-wireless access networks while baseband-over-fiber scheme consumes the most energy.

A reduced nonlinear Volterra filter is applied to 14 Gbaud DP-16QAM and 28 Gbaud DP-QPSK systems for nonlinearity mitigation. An increased reach of 500 km and 1200 km, respectively, is achieved compared to the non-Volterra filter case.

We generate the QPSK signal by utilizing the chirp characteristics of the directly modulated RSOA for the high-speed coherent WDM PON. In addition, we demonstrate the error-free transmission of the 5-Gbps QPSK signal generated by using this technique over 100-km long fiber link without using any optical amplifiers and electronic equalizers.
