<p>Cable networks for television signals, sound signals and interactive services - Part 114: Optical transmission systems using RFoG technology</p>

Scope

IEC 60728-114:2026 describes the system and equipment specification of FTTH/FTTB (fibre to the home/fibre to the building) networks where information is transmitted in both forward and return path directions using RF subcarrier multiplexing technology, and where the return path transmission uses additionally time division multiple access technique imposed by the transmission of the return path signals using a TDMA (e.g. TDMA mode of DOCSIS) protocol. Such systems are called RF over glass (RFoG) and consist of an RFoG optical network unit (R-ONU), an optical distribution network based on xPON structure, and an RFoG optical return path receiver. This document specifies the basic system parameters and methods of measurement for RFoG systems in order to assess the system performance and its performance limits.
The detailed description of physical layer is out of the scope of this document and it does not include IP transport technologies.
