Precautions for fiber optic home construction


Fiber-to-the-home, although just pulling a fiber-optic cable to the user's home, is not as simple and easy as many users imagine. In many parts of China, there are still some hurdles to overcome for fiber-optic broadband to enter the home.


Fiber to the Home (FTTP), also known as Fiber to the Home (FTTH), refers to a broadband telecommunications system. It is based on fiber optic cables and uses optoelectronics to deliver multiple services such as telephone triple play, broadband Internet and television to the home or business.


Fiber to the home construction

Optical fiber communication is widely used as a medium for information transmission due to its unique advantages of anti-interference, light weight and large capacity. It is the most economical and efficient way to use existing transmission lines to lay optical cables. China has a vast territory and is very rich in power line resources. There are 25,094.16 kilometers of 500KV and 330KV power lines in the country, 107,348.06 kilometers of 220KV lines, and a total of 310,000 kilometers of 110KV lines, so my country's power lines have very considerable application prospects.

Richard Mack, chief expert of CRU's optical fiber and cable market, once mentioned that "Through the 40-year development history of optical fiber networks, the market is currently in the era of fiber-to-the-home. That is to say, many telecom operators, especially those in mature markets, are Massive coverage of fibre-to-the-home is being built or has already been achieved. And many of these operators are making plans for the next phase – 5G and the age of IoT.”


Fiber to the home still needs to overcome three obstacles

Fiber-to-the-home is the general trend, and some areas have already realized it. However, there are also many places where fiber-optic broadband is installed, and there are still three obstacles.


First of all, the property management of the community is obstructed, causing the "last mile" of optical fiber to the home to get stuck. It is understood that in the process of promoting the "Optical Network City", the optical fiber to the home in some residential quarters encountered property management obstruction, and even some property management companies demanded high household fees from the ground, resulting in the optical fiber reaching the door of the community, but not reaching the user's home. . Due to property and other reasons, nearly 200 real estates in the province could not enter the construction site for optical fiber reconstruction, and many users could only look at the optical fiber and sigh.


Secondly, in some established communities, due to construction problems, the hidden pipes are blocked, and the property management is not allowed to go through the open wires, resulting in the optical fiber entering the building, but not entering the user's home separated by a wall. In order to meet the needs of users, telecommunications installers can only install CP pipes in places in the corridor that do not affect the vision, such as laying CP pipes at the top corners of the staircase, which increases the difficulty of construction.


Third, many optical fiber lines in residential areas covered by optical networks only have vertical lines and no horizontal lines in the unit building. The installer needs to open the ceiling and lead the lines to the user's home piece by piece. Although China Telecom adopted a two-person installation team and achieved good results, there is still a gap between the urgent expectations of users to quickly install optical fibers.



In general, in the absence of other epoch-making technologies, fiber-to-the-home is the ultimate goal of broadband access to telecommunications networks in the next few years or even decades. It will drive the development of a series of related industries and form a digital The market size of hundreds of billions or even trillions of yuan. Therefore, fiber-to-the-home is one of the core technical drivers for the telecommunications industry to maintain sustainable development, and it is also an important tool for the telecommunications industry to promote social informatization.


As the future backbone of the communication transmission system, the anti-interference and anti-electromagnetic properties of optical fiber are more suitable for the future demand of human beings with large amount of information and high precision, and the low price makes the transmission medium of optical fiber can be widely promoted. . But relatively speaking, in order to popularize fiber-to-the-home well, there are still many problems to be solved, such as the technology and hardware of the transmitting and receiving ends, and the speed of the transmission system. For users, the processing of large amounts of information requires better computers. Therefore, the improvement of communication systems also depends on the rapid development of computer technology to a certain extent.
