Description

A kind of direct-connected optical branching device rack

Technical field

The utility model relates to a kind of communications industry is used for the direct-connected optical branching device rack of FTTX engineering, belong to logical Communication network equipment technical field.

Background technology

At present, the optical branching device rack of FTTX engineering cell machine room on the market, mainly adopts traditional jumping fiber to connect, needs Additionally to purchase jumping fiber, relatively costly, safeguard inconvenience.

Content of the invention

For the deficiency of traditional product, this utility model provides a kind of direct-connected optical branching device rack.It is in outside line area master Dry, distribution adopts direct-connected structural modelss, and optical branching device adopts tray-like structure, by the tail after outside line area trunk, distribution welding Fine fixed length simultaneously directly leads out, and the route opened immediately and optical branching device are directly connected to, and the route that wouldn't open is deposited in idle route Storage module management.

Technical problem to be solved, traditional optical branching device rack has 2 defects：1st, tray of optical splitter takies outside line support Disk position, causes whole volume less than normal；2nd, backbone optical cable and optical distribution cable are connected after welding open-minded respectively with jumping fiber, and cost is relatively Height, communication failure point is many, Insertion Loss high；3rd, slack stores in cabinet in a large number, and route querying is difficult, follow-up maintenance inconvenience.

In order to realize foregoing invention purpose, the technical solution adopted in the utility model is：

A kind of direct-connected optical branching device rack, including cabinet, is sequentially set with described cabinet, optical cable is fixed from top to bottom Stripping grounding device, drag fine plate, the first wire loop, outer wire module, the second wire loop, tray of optical splitter, the 3rd wire loop, idle route Memory module；Described outer wire module is some direct-connecting trays.

Preferably, totally 4 groups of described first wire loop, each two groups of left and right.

Preferably, totally 26 pieces of described direct-connecting tray, middle 4 pieces become end trunk, and each 11 pieces of left and right becomes end distribution.

Preferably, totally 2 groups of described second wire loop, respectively have below described outer wire module and described tray of optical splitter One group；Described tray of optical splitter has 20 groove positions, each 10 of left and right；Described idle route memory module is single port formula, Totally 26 vertical bar, every vertical bar 12 port.

The beneficial effects of the utility model are：Achieve the direct-connected theory of transmission contact, reduce adapter and jumping fiber, thus Reduce line cost, decrease communication failure point, reduce Insertion Loss, lift network security；Outside line area tail optical fiber fixed length, and be equipped with Orderly idle route memory module is clear using, maintenance interface.

Brief description

Fig. 1 removes structural representation behind the door for this utility model.

Wherein, 1, cabinet；2nd, optical cable fixation peeling grounding device；3rd, drag fine plate；4th, the first wire loop；5th, outer wire module；6、 Second wire loop；7th, tray of optical splitter；8th, the 3rd wire loop；9th, route of leaving unused memory module.

Specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in figure 1, outer wire module 5 adopts special direct-connecting tray, after tail optical fiber and optical cable welding, directly lead out pallet, and It not be used in terminal on adapter；Setting idle route memory module, the route that storage is not temporarily opened can store thereon；Out The tail optical fiber fixed length of wire module is 1.2m it is ensured that arbitrarily route connects equal sufficient length and will not leave the remaining of needs storage in cabinet Long；Optical branching device is positioned in purpose-made pallet, and left and right respectively arranges the groove position of 10 tray of optical splitters, less than 16 points of optical branching Device pallet accounts for a groove position, 32 points account for two groove positions, 64 points account for four groove positions, miniature and cassette splitter can be adapted to.

This utility model, in use, optical cable enters cabinet 1, is fixed and stripping on optical cable fixation peeling grounding device 2, Optical cable strengthening core is grounded.Optical cable after stripping, by dragging the management of fine plate 3 and the first wire loop 4, enters outer wire module 5 and tail optical fiber Welding, totally 26 pieces of outer wire module, wherein middle 4 pieces become end trunks, and each 11 pieces of left and right becomes end distributions.The tail optical fiber that welding finishes is not eventually End directly goes out pallet, through the management of the second wire loop 6 and the 3rd wire loop 8, needs second wire loop 6 that is routed across opened to divide with light Road device pallet 7 corresponding port connect, wouldn't open be routed through idle route memory module 9 store, leave unused route storage Module 9 is single port formula, totally 26 vertical bar, every vertical bar 12 port, and every idle route corresponds to a private port, conveniently looks in the future Look for maintenance.
