Abstract

The utility model provides a non-equilong branched trunk optical cable, which comprises a plurality of branches, a plurality of MOP wires, a trunk and two branchers, wherein the number of the branches is the same as that of the MOP wires; one branch is spliced with each of two ends of the trunk; one brancher is connected with the branches, and the other brancher is connected with the MOP wires; the branches are sequentially arranged from long distances to short distances away from an external server; and length differences between every two adjacent branches are the same. According to the equidifferent branched optical cable, the branches with the same differences are adopted for matching with a server, redundant cables are avoided, and the daily management is facilitated.

Description

Not isometric branch backbone optical cable

Technical field

The utility model relates to communications optical cable, particularly a kind of not isometric branch backbone optical cable of saving energy consumption, being convenient to manage.

Background technology

The backbone optical cable that traditional wiring is used in order to practice thrift its cost, is made the backbone optical cable that meets stock size branch usually.But in data-center applications, the difference of the distance of the maximum that produces owing to difference highly between server and the server can reach 42U.If adopt conventional isometric branched cable, at first must satisfy the length of maximum distance tie point.But in this manner, the redundant one section cable of inferior tie point far away meeting, nearer tie point then can the longer one section cable of redundancy.In a word, near more from tie point, redundant cable is many more.Will produce following defective like this: 1, according to the unified length of cable of formulating of maximum distance, the cable of near point can produce the redundancy of different length, causes the cable waste; 2, unnecessary cable can cause a lot of troubles in data center's storage, because the size of a frame is fixed, the gap between the server is fixed, and unnecessary cable storage area is less, extruding easily, damage; Even 3 cables can be stored in the frame, also can cause ventilation not smooth, refrigeration reduces, and increases the maintenance cost of data center; 4, unnecessary cable causes very big inconvenience for the staff of data center to current check and the maintenance that optical cable carries out.

The utility model content

The fundamental purpose of the utility model is to provide a kind of not isometric branch backbone optical cable, and its length rationally, does not produce redundant cable, cuts down the consumption of energy, is convenient to daily management.

In order to achieve the above object, the utility model adopts following technical scheme:

A kind of not isometric branch backbone optical cable; It comprises several branches, MOP line, trunk, the splitter identical with number of branches, the said trunk two ends splitter of pegging graft respectively, said two splitters; One connects said several branches; Another connects said MOP line, and by far and closely being arranged in order, and the length difference of adjacent two branches is apart from identical according to external server distance in said several branches.

Described not isometric branch backbone optical cable, the length difference distance of its said adjacent two branches is interval and the server height sum between adjacent two external servers of branch.

Described not isometric branch backbone optical cable, the outside surface of its said branch, trunk, MOP line is provided with composite bed, and composite bed is made up of flame-retardant layer and enhancement Layer.

Described not isometric branch backbone optical cable, the mica waterstop that its said flame-retardant layer is a mixed type.

Described not isometric branch backbone optical cable, its said enhancement Layer is two-sided plastic-coated steel band, steel band coats water blocking layer outward.

Owing to have said structure, the utility model is compared prior art has following advantage:

1, the not isometric branch of the utility model backbone optical cable, its length is provided with rationally, does not produce redundant cable, reduces the energy consumption that cable is produced, and reduces cost.

2, the not isometric branch of the utility model backbone optical cable, cable is provided with rationally, does not take the frame redundant space, is convenient to staff's current check and maintenance.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

As shown in Figure 1; A kind of not isometric branch backbone optical cable that the utility model provides, it comprises three branches 2, three MOP lines 5, trunk 4, splitter 3, the said trunk 4 two ends splitter 3 of pegging graft respectively; A splitter 3 these three branches 2 of grafting of upper end; The top Connection Service device joint 1 of these three branches 2, a splitter 3 these three MOP lines 5 of grafting of lower end, the top of these three MOP lines 5 connects MOP termination 6.Distance between these three branch's 2 bases and its external server is by far and closely being arranged in order, and the length difference of adjacent two branches 2 is apart from identical.The length difference distance of these adjacent two branches 2 is interval and the server height sum between adjacent two branches 2 external servers.For example, arrange, suppose that the length of the branch 2 farthest in first frame should be N according to the server in the data center; Calculate the distance between the external server of the external server of first branch 2 and second branch 2; Record the height of server itself again, be assumed to be U, then the length of second branch 2 should be N-(server interval+server height U); And the like; The length of the 3rd branch 2 should be N-(server interval+server height U)-(server interval+server height U), because the interval appropriate design between the server should be identical, therefore; The length of the 3rd branch 2 should be N-2* (server interval+server height U), and the length of n root branch 2 should be N-(n-1) * (server interval+server height U).The not isometric branch backbone optical cable that is provided with like this can effectively be saved product and installation cost; The correct calculation length of cable customizes branch by factory by length again, has solved the problem that cable stores in data center, and switch is between the server, and the length of cable between server and the server is suitable, good looking appearance; The cable fixed length can not stopped up the server gap, reduces ventilation effect and refrigeration; Neat cable helps the maintainer of data center to discern the tie point of cable, is convenient to the current check and the maintenance of cable.

Described not isometric branch backbone optical cable in order to improve the heat resistant fire-proof performance of optical cable, can also be provided with composite bed at the outside surface of branch 2, trunk 4, MOP line 5, and composite bed is made up of flame-retardant layer and enhancement Layer.Said flame-retardant layer can be the mica waterstop of mixed type, and said enhancement Layer can be two-sided plastic-coated steel band, and steel band coats water blocking layer outward, and water blocking layer can be by waterproof material commonly used, and for example resinous material is processed.
