In this paper, the authors present long reach Wavelength Division Multiplexing Passive Optical Network (WDM-PON) system capable of delivering downstream 40Gbit/s data and upstream 40Gbit/s data on a single wavelength. The optical source for downstream data and upstream data is mode locked laser at central office and Reflective Semiconductor Optical Amplifier (RSOA) at each optical network unit. They use four RSOAs at each optical network unit for the 40Gb/s upstream transmission. The operating wavelengths of these RSOAs are separated by the free-spectral range of the optical demultiplexer at the central office and Remote Node (RN) for demultiplexing the WDM channels.
