We investigate wavelength division multiplex passive optical networks (WDM-PON) for next generation optical access. These have to cope with continuously increasing bandwidth demands from private and business customers as well as from mobile backhaul applications. In residential access in the near future data rates of more than 1 Gb/s per user are envisioned. For business customers and mobile backhaul 10 Gb/s and more will be needed shortly. In this article system designs will be discussed and challenges and solutions on the component and (sub-) system level will be presented. Furthermore, cost considerations and energy consumption will be investigated. Also recent results from standardization bodies and the impact on the system design will be shown.
