With the continuous acceleration of the transformation process in the digital age, it is the general trend to increase the construction of 5G networks and gigabit optical networks. The promotion of "dual gigabit" coordinated development has brought about the upgrade of gigabit home broadband. FTTR (Fiber to The Room) technology, by directly extending the optical fiber to each room of the user, further upgrades the traditional fiber-to-the-home to fiber-to-the-room, and provides a new Gigabit network coverage solutions, which will be one of the technical directions for future Gigabit home broadband upgrades.

         The FTTR technical solution is to carry out home networking through optical fiber media, deploy FTTR main gateways in distribution boxes or key locations, take the main gateway as the core, and form an FTTR optical network through optical splitters and single-core bidirectional optical fibers. The FTTR master gateway is connected to the OLT in the uplink, and connected to multiple slave optical routers in the downlink through optical fibers and optical splitters. The optical router supports Gigabit Ethernet ports and Wi-Fi 6, and enters each room through optical fibers to realize wired and wireless connections in each room of home users. Gigabit network coverage. The optical network is composed of optical cables, optical splitters and other components, which together build the infrastructure of the home intranet. The network management platform is responsible for collecting home network information and summarizing and reporting it, so as to fully realize the operation and maintenance management of the home Gigabit network.

The main components of the FTTR network include ONUs, optical splitters, fiber optical cables, and optical fiber panels. ONU is an all-in-one device with WiFi6 routing.

Main ONU：connect to OLT uplink through XG(S)-PON or 10G EPON, undertake Gigabit/10G fiber-to-the-home, and provide downlink optical routing interface.

Slave ONU：Connect to the master ONU upwards through indoor fiber optical cables, and provide Internet access services for terminals downwards.

Optical splitter：realize the coupling, branching and distribution of optical signals.

fiber optical cables： realizes long-distance optical signal transmission. PS: When using the original network cable to upgrade FTTR, it is required to use Cat5 network cable or Cat6 network cable for home broadband. If you use a Cat5 network cable, you need 8 cores.

Optical fiber panel：Complete the access and port output of the dual-core optical fiber, meet the requirements of the bending radius of the optical fiber, and provide safety protection for the fiber core.
