In this paper, an approach for wavelength generation in the C-band at the remote node of a passive optical network is experimentally demonstrated. The upstream wavelength is established in a loop configuration by a remotely pumped Erbium-doped fiber and a wavelength selective feedback. By combining this upstream channel modulated at 1 Gb/s by a cheap and simple device at the customer premises with a downstream signal modulated at 10 Gb/s, a cost-effective solution for long reach access networks with a high density of possible customers is given by taking advantage of utilizing the L-band for separation of the data streams and extending the numbers of useable wavelength channels.
