      An upgrade at the physical layer regarding unbundling and dynamic bandwidth provisioning of a wavelength division multiplexed access network is presented. The capability of a reflective modulator to act as a photodetector ...

    • High customer density PON with passive amplification through distributed pump for > 1:1000 tree split 

      Schrenk, Bernhard; Bauwelinck, Johan; Bonada Bo, Francesc; Lázaro Villa, José Antonio; Xing-Zhi, Qiu; Chanclou, Philippe; Prat, Josep (2011-07-01)
