Abstract: New home all-optical network technologies related to Fiber to The Room (FTTR) are proposed. Based on three categories of technologies covering the bottom infrastructure, network management, and service assurance, ZTE has achieved a series of technological innovations and application improvements: The FTTR passive optical network (PON) chipsets are developed to realize the point-to-multipoint (P2MP) architecture functions of the master and slave gateways; the technical guide of home optical fiber construction is formulated to solve the difficulties in optical fiber distributed network (ODN) cabling construction in FTTR implementation; a smart management cloud platform is developed to implement manageability of the FTTR network, including network topology management and performance data collection; the five-dimensional rating system and STA handover model analysis are proposed to realize the whole-home roaming "selected well" and "cut quickly", building the roaming handover delay as low as 20 ms. It is pointed out that the home network is evolving rapidly, and FTTR will face more challenges. ZTE Corporation will continue to tackle the key problems of FTTR technology and promote the new infrastructure of home network.
