Fiber home becomes the trend, still need to overcome the three obstacles

Optical fiber home, although only to pull a fiber line to the user's home, but not as many users imagine that simple and easy. In many parts of China, optical broadband access to the home still needs to overcome some obstacles.

FTTH (FTTP), also known as fiber to the house (FTTH), refers to the broadband telecommunications system. It is based on fiber optic cables and uses optoelectronics to deliver multiple services such as telephone three playback, broadband Internet and television to the home or enterprise.
Optical fiber communication is widely used as information transmission media because of its unique anti-interference, light weight, large capacity and so on. It is the most economical and effective to use existing transmission lines to lay optical fiber cables. China is vast in area and rich in power line resources. The power lines of 500KV and 330KV in China are 25094.16 kilometers, and the 220KV line is 107348.06 kilometers, and the total number of 110KV lines is 310000 kilometers. Therefore, the power lines in China have a very promising application prospect.
CRU optical fiber cable market chief expert Richard Mack said "40 years of development in the market at present is in the optical fiber network, fiber to the home, that is to say, many telecom operators, especially the mature market operators, are under construction or has achieved large-scale coverage of the fiber into the door. And many of them are making plans for the next stage - the advent of the 5G and the Internet of things."  FTTH is the general trend, some areas have been achieved, but there are many places to install broadband optical fiber, still faces three obstacles.
First of all, the residential property management way, lead to fiber to the home "last mile" jam. It is understood that in the "network city" in the process of advancing, fiber to the home in some residential areas encountered Wuguan block, even some Wuguan company hike for exorbitant home fees, lead to fiber to the cell door, but not to the user's home. Because of the property and other reasons, the province has nearly 200 real estate can not approach the implementation of fiber construction, many users can only watch helplessly fiber.Secondly, in some district has been built, by construction, pipe blocked, Wuguan and not allowed to take the open air, causing the fiber into the building, but can not enter a user's home. In order to meet the needs of users, telecommunications installation personnel only in the corridor does not affect the visual areas, such as building the top corner of the CP stairway laying pipe matchmaking, construction difficulty.
Again, a lot of small fiber optical network coverage in line unit building only longitudinal lines, no transverse lines, installation personnel need to open the ceiling, the line length a length lead to the user's home. Although China Telecom has adopted two people and a group of installation team, and achieved good results, but there is still a gap with the urgent need for rapid installation of optical fiber users.
In general, there is no other landmark technology, fiber to the home is the next few years or even decades of telecommunication network broadband access of the ultimate goal, it will lead to a series of related industries, the formation of hundreds of billions or even trillions of market size. Therefore, FTTH is one of the core technologies to maintain the sustainable development of the telecommunications industry, and is also an important tool for the telecom industry to promote social informatization.
As the future backbone of the communication transmission system, the anti-interference of optical fiber, anti electromagnetic characteristics more meet the needs of future human information, high precision, and the low price makes the optical fiber transmission medium can be widely promoted. But relatively speaking, FTTH penetration to achieve very good, there are a lot of problems to be solved, such as transmitter and receiver technology and hardware, and although transmission speed can be referred to G bytes of speed, but for users, with a large amount of information, need more and better computers to deal with, so communication system, improve the rapid development, but also to some extent depends on the computer technology.
