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...
Cloud Radio Access Network (C-RAN) and Fixed Mobile Convergence (FMC) receive a lot of attention recently because of the cost decrease and the performance improvement that they represent for telecommunications' operators. In this paper, a fixed/mobile convergent architecture is introduced based on the integration of fronthaul links with fiber access infrastructure and central office assets. Tests...
We describe a heterodyne detection method able to measure precisely the wavelength drift of directly modulated lasers under burst mode operation. In addition to the thermal drift (up to 25GHz), the adiabatic chirp frequency modulation should not be neglected.
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.
Performances of a symmetrical 10G-PON prototype are explained and a Reach Extender for both G-PON and 10G-PON systems based on only two SOA is proposed.
This paper presents a view of the trends and perspectives in the next generation of optical access solutions following the 10Gbit/s Passive Optical Networks.
