Abstract
The wavelength division multiplexing passive optical network (WDM-PON) incorporated with colorless optical network units (ONUs) and centralized light source is the most promising approach for next generation PON. A cost-effective architecture utilizing coherent detection for upstream (US) signal is proposed to enlarge the reach of such WDM-PON systems. Simulation results show that a symmetric 10-Gbps WDM-PON with 80km error-free transmission is realized without using any optical amplifiers.
