The structure has the characteristics that the box-type optical splitting installation region is additionally arranged, and the box-type optical splitters are utilized to increase the number of adapted users.
Description
Technical field
The utility model relates to optical communication field, particularly the FTTH fiber cable cross connection box.
Background technology
Be difficult to the restriction that difference Cheng Xiaoxin counts distribution sidelight cable due to the conventional cable cross-connecting box in original arterial grid or LAN (Local Area Network), cause the backbone optical cable rack to establish that investment is large and resource utilization is low, this has restricted the FTTH fast development that Fiber to the home builds.At present, in the conventional cable cross-connecting box, owing to not being combined with optical branching device, its maximum user is than half of optical cable joining casing place capacity just often, and all counts the user for large core and use.
The utility model content
The purpose of this utility model is to provide a kind of use optical branching device for the deficiency that solves above-mentioned technology, improves the utilization factor of backbone optical cable, reduces the optical cable input cost, adapts to the FTTH fiber cable cross connection box that day by day increases user's request.
In order to achieve the above object, the FTTH fiber cable cross connection box that the utility model is designed, consisted of by base and casing, casing is arranged on base top, described casing internal upper part one side becomes petiolarea for optical cable welding, opposite side is boxlike light splitting installing zone, become the bottom of petiolarea to be provided with optical cable straight melting zone at optical cable welding, bottom in optical cable straight melting zone is provided with optical cable baring/fixed area, by fixing and mounting bracket, cassette splitter is installed in boxlike light splitting installing zone, and described fixing and mounting bracket can with the optical branching device universal fit of 1 * N and 2 * N.The characteristics of this structure are to have increased boxlike light splitting installing zone, utilize the boxlike optical splitter to increase adaptive number of users.
In order to adapt to, adaptive needs are installed, described boxlike light splitting installing zone is other is provided with storage line district, convenient install adaptive, and storage lineation line.
Count user's use in order to adapt to little core, the other rubber-covered wire cable fixing device 10 that is provided with of described optical cable baring/fixed area.
The resulting FTTH fiber cable cross connection box of the utility model, inner structure to original traditional optical cross box is improved, increase the installation parts of optical branching device, these parts 1 * N, the various model optical branching devices of 2 * N are installed general, spatially do not take original conduit number in fiber cable cross connection box, take full advantage of the cross-connecting box inner space, simple in structure, easy for installation, configuration is clear; Boxlike light splitting by reference (1:N) increases distribution side user capacity; Adopt highdensity integrated fibre melting disc for backbone optical cable welding, one-tenth end, to save limited operating space; Increase rubber-covered wire cable fixing device 10 at the optical cable baring fixed area, adapt to little core and count user's use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the FTTH fiber cable cross connection box that the present embodiment is described, consisted of by base 2 and casing 1, casing 1 is arranged on base 2 tops, described casing 1 internal upper part one side becomes petiolarea 3 for optical cable welding, opposite side is boxlike light splitting installing zone 4, become the bottom of petiolarea 3 to be provided with optical cable straight melting zone 5 at optical cable welding, bottom in optical cable straight melting zone 5 is provided with optical cable baring/fixed area 6, by fixing and mounting bracket 7, cassette splitter 8 is installed in boxlike light splitting installing zone 4, and described fixing and mounting bracket 7 can with the optical branching device universal fit of 1 * N and 2 * N.Described boxlike light splitting installing zone 4 is other is provided with storage line district 9, convenient install adaptive, and storage lineation line.The other rubber-covered wire cable fixing device 10 that is provided with of described optical cable baring/fixed area 6.
When installing and using this FTTH fiber cable cross connection box, take 288 cores as example, the number of users of conventional cable cross-connecting box and backbone optical cable capacity requirement number equate, are 144 cores; When being 1:32, this novel FTTH fiber cable cross connection box number of users can increase by 31 * 8/2=124 core at most in theory on the original basis when cassette splitter 8, and backbone optical cable capacity requirement number is only the 144-124=20 core.So in the FTTH of 288 cores fiber cable cross connection box after 8 1:32 optical branching devices of configuration, backbone optical cable demand 20 cores in theory, number of users can reach 268 cores, can increase at most number of users 124 cores than conventional cable cross-connecting box.
Wherein 256 core subscriber optical cables open stripping fixing (it is fixing by special rubber-covered wire cable fixing device 10 that little core is counted covered wire cable) after the integrated disk welding tail optical fiber by the connection of fiber active linker, light signal is gone upward to the distribution side of corresponding boxlike optical splitter, then 8 boxlike optical splitter pool sides are continued up by every single core tail fiber again, then single core tail fiber is connected in 12 core integrated disks, carry out corresponding welding one by one with 8 core fibres of trunk sidelight cable, last optical cable signal converges one by one through local side machine room OLT equipment.
Therefore, can find out by above description process, the research and development of novel FTTH fiber cable cross connection box equipment are mainly that original fiber cable cross connection box inner structure is transformed.At first increase distribution side user capacity (when the boxlike optical splitter is 1:32, backbone optical cable capacity requirement 20 cores) by being combined with cassette splitter 8, greatly reduce like this construction demand of backbone optical cable circuit; Then newly-increased optical branching device erecting device takes full advantage of the optical cross box inner space, does not take existing capacity conduit number, additionally increases user's request 124 cores; Simultaneously quote the covered wire cable holder at the optical cable fixed area and count covered wire cable user's demand to adapt to little core.
