FTTR (Fiber to The Room) fiber deployment to the room design solution is a solution based on FTTB (Fiber to the Building) and FTTH (Fiber to the Home), so that each room can reach more than a gigabit network speed, to achieve full coverage of the whole house wired and Wi-Fi dual gigabit.
The innovative applications of the “meta-universe” are emerging, and users are putting higher and higher demands on the bandwidth, latency and jitter of the network. In recent years, 4K/8K UHD video, cloud VR, online education, online office, live video and other services have gradually become popular, and connecting various terminals via Wi-Fi has become a norm, but the lack of Wi-Fi bandwidth and poor coverage has led to frequent video and game lag and poor business experience, which has become a pain point for a large number of users. And in fact, the bandwidth of broadband services handled by home users is generally high, but its high bandwidth capacity is far from being fully developed.
FTTR technical solutions and network architecture
Fiber optics cable, as a vital information carrier in modern communication networks, has a series of advantages such as high capacity, long transmission distance and strong anti-interference capability, which can be subdivided into 4 schemes according to the different transmission media of currently deployed wired communication networks.
All four deployment schemes are based on different transmission media and transmission protocols, and their transmission bandwidth and stability are different. Wi-Fi relay networking based on 802.11 protocol is subject to large environmental interference, rapid fading and poor stability; Powerline Adapter networking based on G.hn protocol, its link sharing mechanism leads to serious deterioration of multi-device networking performance and is not suitable for large bandwidth data transmission; Ethernet protocol-based network cable networking relies heavily on the quality of network cables, and the current indoor Most of the pre-buried wires are Category 5 wires, making its transmission rate only up to 100Mbit/s, which cannot experience the application of high speed demand; while the all-optical networking method based on PON protocol uses optical fiber as the only transmission medium, with mature operation and maintenance protocols, high reliability, and a stable return bandwidth of more than 1G, which is the optimal choice for future communities and future families.

FTTR technology networking architecture contains FTTR optical gateway, edge ONT, supporting fiber components.
FTTR optical gateway: new network equipment type, network location between the OLT and edge ONT, up through the home optical network to connect the OLT, down to provide home optical network to connect the edge ONT. compared to FTTH networking, FTTR optical gateway for FTTR networking provides greater flexibility.
Edge ONT: connected to user devices and upward to FTTR optical gateway through home optical network. In terms of function, match the business development needs, provide more convenient access, higher access quality assurance, such as room-based functional positioning, provide exclusive game edge ONT, learning edge ONT.
The matching fiber optic components include optical sockets, optical cables, cables with connectors, splitters, ATB (Access Terminal Box), etc.
FTTR networking to achieve 3 goals: first, super gigabit, Wi-Fi 6 super gigabit into the room; second, a deployment of long-term effective, whether the later network upgrades to 10G bandwidth or 100G bandwidth, no need to replace the network architecture and equipment; third, intelligent operation and maintenance, fiber directly into the room, the integration of fiber and Wi-Fi to achieve the whole family a network, seamless roaming between Wi-Fi, while you can view the network status, maintenance and management through the cell phone APP.
FTTR application and promotion
Compared with traditional indoor wired network solutions, FTTR all-optical indoor network solutions have epoch-making significance. FTTR all-optical networking breaks through the limitation of the number of traditional networking Ethernet ports to achieve flexible expansion of networking, thus making the space for Wi-Fi networking expand several times; replacing traditional network cables with optical fiber to achieve whole-house optical fiber networking. Traditional networking methods to FTTR networking transformation.
FTTR all-optical indoor network solution to replace the original indoor Category 5 wire with optical fiber, FTTR optical gateway can be adapted to common FTTH and FTTB access network management. But FTTR edge ONT is not the network element in the access network management, in order to achieve management, edge ONT are controlled through the core ONT, the access network through the management of the core ONT indirectly realize the management of the edge ONT.
1. It is more troublesome to transform the fiber optic in the rooms that have been laid out with network cables, and you need to rearrange the fiber optic in each room.
2. The overall cost of the whole package is more expensive at present.
