30 Gbit/s downstream capacity of cost-effective colourless WDM-PON based on injection-locked Fabry-Perot lasers
27 August 2009
A 100 GHz spaced comb, generated by a quantum dash passively modelocked laser, is used as a low-noise coherent seeding source for the colourless wavelength-division-multiplexed passive optical network based on injection-locked Fabry-Perot laser diodes. Error-free downstream transmission over 25 km singlemode fibre of 12 WDM channels at 2.5 Gbit/s with 100 GHz channel spacing is experimentally demonstrated.
