FTTH construction must follow the five key elements

FTTH project, there are several key elements that must be followed, the correct implementation of these key elements can greatly reduce the project's investment, improve the construction speed, and sufficient space for the upgrade or expansion, to extend the network sustainable and effective operation, upgrade space. FTTH project must follow the following elements: 

1, the location of the position of splitter 

In the passive optical network, splitter position for the implementation of the project plays a vital role. Splitter is a passive device, no power can work, so there is no site selection and installation of too many worries, just need to focus on pipelines and distribution to users. Splitter position is generally not installed on the engine room, usually closer to the user in the selection, and the more intensive users of light around the distribution box. If the splitter installed in the engine room set splitting, and that the advantages of PON not reflected. 
The correct installation position splitter location can bring the following advantages: 

1) to save room to invest in fiber optic cable distribution box 

Reasonable determination of location splitter cable can greatly save the investment. To a 24-core fiber optic cable, for example, if the splitter installed in the engine room, 24-core cable only for room and user distribution box connected, users can only open 24. However, if used in engine room and outdoor splitter connection, then, in accordance with 1:64 split ratio can be covered by 1536. In other words, if the installation can be a reasonable 24-core fiber optic cable instead of a 1536 core cable. 

2) to save room space, improve management capabilities. 

Splitter installed outside the engine room can save rack space. 

2, room location 

In a pure FTTH project, may take up to a room. Because the room of the building involved to take power, management, operations, back-up power, air conditioning, etc., will greatly increase the construction and operational costs. Typically, operators will not set FTTH room in any district, unless a nearby room far away from the user. The carriers usually up to the light installation in the area distribution box or cable connector box. 

3, focus on spectral 
Operators are usually near the user's place in the outdoor centralized splitter. This is a protection for the investment, according to the user can open the case of expansion of the splitter. In other words, when less pre-user can buy a little less light splitter, with the opening of the number of users, increasing the number of splitter. However, the design proposed in the early time to consider adequate expansion space. 

4, reducing the types of fiber optic cable 
In order to facilitate the implementation and management, good design in a passive optical network does not use more than 2 or more cables (not including households covered wire cable). This mainly refers to the cable from the engine room to the user within the assigned box. Rosenberg completed the project, even from the center room to the floor distribution box can only use up to two kinds of fiber optic cable. Reduce the types of fiber optic cable to determine the need to help improve the use of fiber optic cable length will help manufacturers to provide rapid response capability and price competitiveness. 

5, to facilitate expansion 
Current EPON or GPON can indeed be split ratio 1:64, in other words, a PON infrastructure equipment can be with 64 users. And in accordance with 10G-EPON and 10G-GPON standard will reach 1:128 split ratio. But in the current implementation of the basic operators directly in the project will not directly be split ratio 1:64, using the splitter is usually 1:32. Using 1:64 split ratio, meaning the average bandwidth per user EPON can only reach 16M. 
FTTH projects must follow the key elements as the above five, the reader FTTH projects in the implementation of the five factors should be considered to improve the quality of projects.
