What‘s FTTR
It is estimated that many people have understood the concept of "fiber to the home". About ten years ago, China‘s broadband network speed underwent a major upgrade and transformation, with fiber entering thousands of households. During this process, the original ADSL copper cable was gradually replaced by fiber optic, only because fiber optic can carry higher network transmission rates. Normally, "Fiber To The Home" is named "FTTH". At present, except for a few old residential areas, most household users are already using FTTH broadband.
In recent years, the demand for home broadband speed has been continuously increasing, with the large-scale popularization of 500M/1000M broadband and the pilot implementation of 2000M broadband. At the same time, major operators have begun to promote "FTTR broadband". There is only a word difference between FTTR and FTTH, but there are significant differences in their specific meanings. From the promotion of the operator‘s storefront, FTTR seems to be a more advanced technology that can bring users a better online experience.
What is FTTR?
FTTR, the ultimate solution for fiber optic transmission to every room, is gradually upgraded from FTTB and FTTH. Indoor fiber optic is used to replace existing network cables, utilizing the characteristics of large transmission bandwidth, no signal attenuation, and strong anti-interference ability of fiber optic to break through the network speed bottleneck of the original network cables. The room deploys an ONU with WIFI6 all-in-one machine , delivering stable "true gigabit" to every corner of the room, making WiFi ubiquitous like air There is no need to change the wiring for future upgrades to 10 Gigabit
Evolution of Fiber Optic Broadband Solutions
FTTR technology features: FTTR technology refers to the use of optical fibers instead of network cables, laying optical fibers into each room, and interconnecting with home gateways through the deployment of optical networking terminals. 
Combined with dual frequency WiFi, WiFi 6, and other technologies, it ensures the coverage of the entire home network. A home gigabit all optical networking solution based on FTTR (fiber to room) technology, which deploys a main ONU in the home distribution box or home center, with the main ONU as the core, using P2MP/P2P method, based on splitters and single core bidirectional fiber, to construct a home optical network. To put it more plainly, your family used to have "an  ONU", and the implementation of FTTR is to give your family a "group of ONUs". The FTTR networking equipment consists of five types of equipment: master ONU, slave ONU, splitter, fiber optic, and fiber optic panel. The master ONU and slave ONU are all integrated machines with WiFi 6 routing function.

FTTR Advantage
1. Fast speed
The biggest advantage of FTTR is its fast speed. Due to the significantly higher transmission rate of optical fiber compared to traditional copper wire, FTTR can provide extremely high network speed. According to testing, the download speed of FTTR can reach 100Mbps or even higher, fully meeting users‘ high bandwidth needs for high-definition videos, online games, cloud storage, and more.
2. Low latency
The fast propagation speed and low latency of light make network communication smoother, making it suitable for applications that require real-time data transmission, such as online games, video conferences, etc.
3. Anti interference
Fiber optic transmission is not affected by electromagnetic interference, and signal transmission is more stable and reliable, without being affected by adjacent cables or equipment.
4. Strong ability to penetrate walls
FTTR full house fiber optic cables also have strong wall penetration ability, and generally adopt high-end WIFI solutions, which can effectively solve the problem of insufficient home network coverage, allowing people to continuously connect to the internet in every corner of their homes. Compared to traditional WiFi networks, FTTR full house fiber optic cables have stronger wall penetration capabilities.
5. Long transmission distance
Fiber optic transmission distance is long and covers a wide range. Compared to traditional Ethernet cables, FTTR can transmit over longer distances and cover a larger area.
6. Strong scalability
The FTTR network supports multiple users online simultaneously, which can meet the needs of multiple family members using the network simultaneously. In addition, FTTR can also be easily upgraded to higher rates to meet future higher-level network requirements.
FTTR Disadvantages
1. High cost
Although fiber optic cables are very cheap, the current price of FTTR ONU products is still high, and the laying and maintenance costs of the entire FTTR solution are also high, so the price of FTTR is relatively high. Although the long-term usage cost of FTTR may be lower than that of traditional networks, the initial installation cost is still relatively high.
2. High engineering difficulty
The deployment of FTTR networks requires the laying of optical fibers, including underground laying and indoor wiring. These complex installation steps require professional technical personnel to operate, which is more difficult compared to traditional network laying.
3. Laying open line optical cables
The FTTR full house fiber optic cable needs to be laid with open cable, which may damage the decoration. Therefore, before installing FTTR full house fiber optic cables, it is necessary to renovate the home, which will increase certain costs and troubles.
4. Device compatibility
Compared to traditional copper wire networks, FTTR requires different devices and modems to connect to fiber optic networks, which may require users to replace or upgrade their existing network devices.
5. Limited improvement in online experience
FTTR full house fiber optic can improve the speed and stability of home networks, but for some ordinary users, the improvement in network experience may be limited. If the bandwidth of the home network is insufficient or the devices used do not support high-speed networks, even if FTTR full house fiber optic is used, the network experience will not be greatly improved.
In summary, although FTTR full house fiber optic has many advantages, its high cost, engineering difficulty, and dependence on equipment and network also need to be considered. When choosing whether to use FTTR full house fiber optic, it is necessary to weigh and judge based on one‘s own actual situation and needs.
Office and commercial use may be the future of FTTR
FTTR may not necessarily meet the needs of ordinary users, but it can also find suitable scenarios for oneself, such as office and commercial spaces. Like large offices, a large number of employees and equipment have a huge demand and pressure on the network, and higher requirements are also put forward for the coverage area of network signals. Complaining about network congestion may already be a daily behavior among many office workers. In this high load scenario, FTTR can have greater room for development.
In addition, in places such as shopping malls, buildings, airports, hotels, etc., network coverage has always been a difficult problem to solve. Slow internet speed and poor signal are common experiences, and when faced with a large number of people and access devices, conventional networking solutions also appear powerless. At this time, the technical advantages of FTTR are reflected. On the one hand, it is led by the operator and can provide relatively professional networking technology and solutions, while being responsible for the actual results. On the other hand, operators can provide follow-up after-sales maintenance services for this solution, and can also increase or decrease the number of routes based on the actual load.
Compared to individual and household users, commercial users are relatively less sensitive to prices and have a higher demand for maintenance and other services. For operators, from a commercial perspective, the FTTR solution will have higher profits and broader commercial potential in the B-end field. In this regard, we can gain a glimpse of the price gap between commercial broadband and household broadband.
