Abstract: The reuse of existing infrastructure whilst keeping unaffected the legacy equipment is a crucial feature for the evolution of gigabit passive optical networks (GPONs) towards higher capacity wavelength division multiplexed-passive optical networks (WDM-PONs). In this paper, a testbed for the evaluation of simple and cost effective GPON evolutions will be presented. A comprehensive set of WDM-PON architectures based on remote wavelengths distribution and wavelengths reuse for upstream (US) transmission will be proposed. Both 2.5 Gb/s and 10 Gb/s (symmetric traffic) have been taken into account and experimentally evaluated in terms of bit error rate (BER) on the same testing bench. System perspectives and limitations are also discussed.
