Short-term wavelength drift is a critical parameter for Next Generation Passive Optical Networks (NG-PON2). This parameter is measured on a pre-commercial system. A wide wavelength drift is observed, suggesting toughening current recommendations.
Upstream time-dependent wavelength drift of directly modulated lasers under burst-mode operation is measured on a second next generation passive optical network precommercial system. A new measurement method is used to demonstrate that the international telecommunication union (ITU-T) recommendations on maximum wavelength drift excursion should be improved. Considering the proximity of the different...
The versatility of FTTH users i.e. the fact that users have much different characteristics in terms of requirements but also in terms of physical parameters creates an opportunity for FTTH transmission systems to optimize their performance and efficiency.
We demonstrate the co-existence of G-PON, XG-PON1 and TWDM-PON on the same infrastructure by wavelength overlay and measure the wavelength drift during the upstream burst of each technology.
