The strategic objective of the European Union to provide broadband access for all of its citizens and also to develop technologies suitable for worldwide use leads to a number of projects aiming on different stages of the technological evolution of next generation fibre-to-the-X access networks. In order to catch up the revenue gap novel technologies are required that offer reduced CAPEX and OPEX. This can be obtained by a converged metro and access network with enhanced reach and splitting factor. Within the project MUSE for the first time a full-functional prototype of a future 10/2.5Gbit/s XL-PON (eXtra Large Passive Optical Network) system was realized and tested. The prototype systems consists of OLT, ONT, and an intermediate stage, called Metro Access Point (MAP) which contains optical amplifiers and a burst-mode transponder for 2.5Gbit/s. The XL-PON prototype fulfils all major requirements of a future next-generation PON¹. The PIEMAN project which started a year later researches the physical layer of a symmetrical 10 Gbit/s, 32 wavelength, 100 km reach and 512 way split access network² and shows very promising results until today. Both PIEMAN and XL-PON are intermediate steps towards the goal of a fully reconfigurable, fully tuneable combined WDM and TDM access networks which offers a multitude of services on a multitude of wavelength which are routed and activated as the demand requires.
