30 Gbit/s downstream capacity of cost-effective colourless WDM-PON based on injection-locked Fabry-Pérot lasers

Topic « Optical communication »International audienceA 100 GHz spaced comb generation in a quantum dash passively mode-locked laser (QD-MLL) is used as a low-noise coherent seeding source for colourless wavelength-division-multiplexed passive optical network (WDM-PON) based on polarization-insensitive injection-locked Fabry-Perot laser diodes (IL-FP). Error-free downstream transmission over 25 km single-mode fibre (SMF) of 12 WDM channels at 2.5 Gbit/s with 100 GHz channel spacing is experimentally demonstrated
