  • Reusing the existing Optical Distribution Network (ODN) of Passive Optical Networks (PONs) to bring connectivity to residential households together with providing the so-called front-haul (FH) network in Cloud Radio Access Networks (C-RAN) is a promising converged fixed and mobile network architecture envisioned by network operators. This article overviews how to exploit Fixed Bandwidth Reservations allowed in ITU-T XG(S)-PONs and their suitability for the transmission of front-haul (FH) traffic, thus allowing one Remote Radio Unit (RRU) coexist with multiple residential Optical Network Units (ONUs) in the same PON. We explain how to configure such periodic reservations to improve access in the upstream channel of a PON, showing worst-case access delays below 100 mus for eCPRI's functional split IU.
