This white paper introduces an evolved methodology to manage FTTx Optical Distribution Network (ODN) performance. A centralized OTDR-based solution is the core of this evolved methodology, which greatly improves the visibility and operation efficiency in maintaining ODN . With the growing global deployment of Fiber-to-the-Home (FTTH) networks driven by the demand for ensuring high-capacity broadband services, mobile network operators (MNOs) face challenges of excessive energy consumption (EC) of wired optical access networks (OANs). On a. This Technical Specification (TS) has been produced by ETSI Technical Committee Access, Terminals, Transmission and Multiplexing (ATTM). In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and "cannot" are to be interpreted as described. Abstract—This paper discusses novel approaches to improve energy efficiency of different optical access technologies, including time division multiplexing passive optical network (TDM-PON), time and wavelength division multiplexing PON (TWDM-PON), point-to-point (PTP) access network, wavelength. The ODN network devices provide the optical fiber interconnection or cross-connection, optical fiber splicing, optical power distribution/wavelength distribution, and optical path protection functions. Take Fiber-to-the-Home (FTTH) for an example, an ODN network consists of a feeder segment, a. The most important energy management and power-saving methods for Optical Line Terminals (OLTs) and Optical Network Units (ONUs), as key OAN components, are overviewed in the paper.
