By using above technical scheme：What light splitting fiber-dividing box disclosed in this invention and its application method used with tradition
The application method for cutting light splitting fiber-dividing box completely compares, and has the lifting in terms of following four：
1st, fiber-dividing box is divided relative to tradition, one region is communicated using the light splitting fiber-dividing box and application method of the present invention
During covering, the cutting number of optical fiber is reduced.So that one needs to use the region that 24 core optical cables are covered as an example.
As shown in table 1, the use data of light splitting fiber-dividing box provided by the invention and its method.
Table 1

When being divided fiber-dividing box and its application method, its maximum fusing point expense is 3900 yuan.By contrast table 3 and table 4, present invention saves
The expense expenditure of construction.
4th, use, installation process specification, the optical cable arrangement of casing is neat, rule, when there is signal fault in a certain region,
Failure can be rapidly investigated, improves maintenance speed.
By taking 24 core optical cables as an example, there are 4 beam tubes in optical cable, the surface color of 4 beam tubes differs, and has in every beam tube
6 optical fiber, when carrying out point fine using light splitting fiber-dividing box provided by the invention, after first the optical fiber in a beam tube has been divided, followed by
Optical fiber in continuous point of next beam tube, in this case adjacent three light splitting fiber-dividing box connected for the light in a beam tube
Fibre, when in some light splitting fiber-dividing box in user there is communications failure when, can the corresponding beam tube of quick lock in, discharge
Other beam tubes, and promptly investigation maintenance.
When dividing fine using traditional light splitting fiber-dividing box, due to being needed when often opening a light splitting fiber-dividing box by the light in optical cable
Fine all cut-outs, retain the optical fiber that two cores do not connect and are connected on the shunt in case, then will be pulled out after remaining fused fiber splice,
For connecting next light splitting fiber-dividing box.In this case, passed when communication occurs in the user in some light splitting fiber-dividing box
During defeated failure, it is difficult to which it is that main cable Nei Nagen optical fiber failure occurs to find out, maintenance difficulty is added.
In summary, the invention has the advantages that：
1st, by dividing plate by the inside division of casing into two regions, wherein the first area branched away is not cut as placing more
Disconnected optical fiber, optical fiber that two cores or four cores are not connected is chosen by through hole across and into in second area, with optical branching
Device is connected, then the covered wire cable of user is connected to by the output end of optical branching device, is reduced a large amount of optical fiber so as to reach and is cut off
Quantity；
2nd, the welding amount of optical fiber is reduced, light contact loss is reduced, improves the efficiency of transmission of optical cable；
3rd, caused fusion point in work progress is reduced, molten fine expense and labour cost is reduced, reduces construction cost；
4th, use, installation process specification, the optical cable arrangement of casing is neat, rule, can be fast when signal fault occurs in a certain region
Failure is investigated fastly, improves maintenance speed.
