Fiber-to-the-home (FTTP), also known as fiber-to-the-home (FTTH), refers to broadband telecommunications systems. Based on fiber optic cables, it uses photoelectric technology to provide multiple services such as triple play of telephone, broadband Internet and television to homes or businesses.
Fiber-to-the-home is the general trend, and it has already been realized in some areas. However, there are also many places to install fiber broadband, and there are still three obstacles.
First of all, the property management of the community was blocked, which caused the "last mile" of the optical fiber jumper to get stuck. It is understood that in the process of promoting the "optical network city", the fiber-optic home access in some communities was blocked by the property, and even some property companies demanded high fees for the home-entry, resulting in the blocking of the fiber-optic home access. To the gate of the community, not to the user's home. . Due to real estate and other reasons, nearly 200 real estate projects could not enter the site for construction and implement optical fiber transformation, and many users could only look at the optical fiber and sigh.
Secondly, in some existing communities, due to construction problems, hidden pipes are blocked, and property management does not allow open wires to pass through. As a result, optical fibers enter buildings, but cannot be isolated from entering users' homes. against the 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 line of sight, such as laying CP pipes at the top corners of stairs, which increases the difficulty of construction.
The third is that many optical fiber lines in the residential area covered by the optical network have only 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 one by one. Although China Telecom has adopted a two-person installation team and achieved good results, there is still a gap from the urgent expectation 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 telecom networks in the next few years or even decades. It will drive the development of a series of related industries and form a digital market size of hundreds of billions or even trillions. Therefore, FTTH is one of the core technology 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 backbone of the future communication transmission system, the anti-interference and anti-electromagnetic properties of optical fiber are more suitable for the future needs of human beings with large amount of information and high precision. The low price makes the optical fiber transmission medium widely popularized.
