Abstract

A WDM PON(wavelength-division-multiplexed passive optical network) structure using 40Gb/s FSK signal for downstream transmission and 10Gb/s orthogonal FSK/ASK re-modulated signal for upstream transmission is demonstrated. In the downstream direction, a novel FSK modulation scheme based on phase-to-intensity modulation conversion is adopted to generate a FSK signal at 40Gb/s, while orthogonal modulation format is used in the upstream transmission. The performance of the system is studied both with and without scattering. Simulation results show that the PON system can transmit for more than 20km, which is a promising candidate for future high-speed access network.
