—We present a comprehensive set of measurements on the reflective passive optical networks upstream architecture, conceived within the FABULOUS Project, in its four-wavelengths configuration, showing the possibility of dramatically increasing the number of users or the bit-rate per user with respect to single-wavelength operation, demonstrating a 128-Gb/s capacity up to interesting values of optical distribution network losses. In addition, a comparison with the NG-PON2 standardized in G.989 at the same bit-rate is held, showing that accepting to reduce the per-wavelength bit-rate of our architecture to 10 Gb/s in a fourwavelengths network can provide great power budgets. Real-time implementation of the upstream on a FGPA platform is demonstrated as well, showing little penalty with respect to off-line experiments. We, also, theoretically analyze the possible performance improvements when higher-bandwidth modulators are used, and we discuss on the system flexibility offered by our proposal.
