Description
Technical field
The present invention relates to optical communication technique.
Background technology
Along with the propelling of the construction of FTTH, more, higher demand has been proposed for sub-district optical cable introducing and branch, along separate routes fiber cable cross connection box.Traditional fiber cable cross connection box and FTTH with the principle schematic of cross-connecting box like Fig. 1, shown in 2.
FTTH mainly concentrates on following components with the characteristics of fiber cable cross connection box:
1, optical cable welding amount increases: with 288 core fiber cable cross connection boxes is example, is responsible for optical cable, and welding core number is 48 cores; Branched cable, several 288 cores of welding core.Optical cable welding core number amounts to 336 cores, and traditional be 288 cores.In addition, the optional straight melting zone of trunk 96 cores.
2, the optical fiber distributing capacity increases greatly: the wiring part branch comprises that backbone optical cable arrives user's tail optical fiber to shunt, shunt, and adding up to distribution core number is 336 cores, has increased more than one times than traditional 288/2=144 core;
3, tank capacity requires to increase greatly: traditional relatively cross-connecting box, box house have increased welding amount, optical fiber splitter, have joined fine space, optical cable storage etc., require casing that enough spaces are arranged;
4, the requirement of management; Owing to join the increasing of fine capacity, the differentiation and the management of inner tail optical fiber had higher requirement.
To the application of FTTN, there are several kinds not have jumper connection fiber cable cross connection box form in the prior art, division is following:
A, " left and right sides is distributed " no jumper connection fiber cable cross connection box:
This cross-connecting box is a normative reference with group's telecommunications, and interior layout is a left and right sides structure, and the left side is trunk cable welding, shunt installation, optical cable baring etc., and the right is the branched cable welding and is stored as the master.
The gauche form cross-connecting box has following characteristics:
Backbone optical cable is introduced from the casing left side, and the welding area is on the upper left side; Optical fiber splitter is positioned at below, backbone optical cable welding area; After branched cable is fused into end on the right, with tail fiber disc around mode be stored in and join cable and store up in the fine box; When needing jumping fiber, with the tail optical fiber of branched cable part, from store up fine box, take out, jumper connection is to the shunt on the left side, and the completion user is open-minded;
Advantage: interior layout is clear, and function distributes rationally, does not have " jumper connection " of optical patchcord, has reduced half the adapter node and consumption;
Shortcoming: when tail optical fiber distribution amount was big, the tail optical fiber route was difficult to distinguish and management, and maintenance difficulties is big.
B, " distributed up and down " no jumper connection fiber cable cross connection box
The characteristics of this cross-connecting box are, the welding of branched cable and shunt lay respectively at the upper and lower sides of casing, and the inner structure synoptic diagram is following:
The characteristics of distributed cross-connecting box have up and down: the casing lower end is optical cable baring and idle tail wires of fiber optics centralized stores point; All optical cable weldings are distributed in casing top with becoming to hold; After backbone optical cable is fused into end, be directly connected to the input port of shunt; User's branched cable Cheng Duanhou, realizes connecting to shunt through the fine groove jumper connection of middle reason; The idle tail optical fiber that user's branched cable does not connect, " administrative center " bottom all being stored in; All walk fibre, all through the fine groove of middle reason.
Advantage: interior layout is clear basically, walks fine concentrating, and does not have " jumper connection " of optical patchcord, has reduced half the adapter node and consumption;
Shortcoming: the passage of tail optical fiber is too concentrated, and is more crowded; Especially when tail optical fiber distribution amount was big, the tail optical fiber route was difficult to distinguish and management, and maintenance difficulties is big.Practice finds that the engineering operation easier is bigger through practical project.
Know that by above-mentioned analysis several kinds of fiber cable cross connection boxes all have common characteristic, but when simultaneously all existing the optical fiber consumption big, difficult the differentiation and unmanageable deficiency.
Summary of the invention
Technical matters to be solved by this invention is that the fiber cable cross connection box that a kind of internal wiring is succinct, be convenient to administer and maintain is provided.
The technical scheme that the present invention solve the technical problem employing is; Fiber cable cross connection box comprises that shunt district, welding panel and optical cable insert the district, is characterized in that; The shunt district comprises the shunt mounting interface that walks abreast; The welding panel comprises the fusion joining disk mounting interface that walks abreast, between shunt district and the welding panel be the bus-type optical line by the district, said bus-type optical line is provided with bus-type optical fiber constraint mechanism by the district.
Fiber cable cross connection box inside sets gradually optical cable from bottom to top and inserts district, welding panel, bus-type optical line by district, shunt district; The fiber buss path that bus-type optical fiber constraint mechanism forms is the U font; The shunt mounting interface in shunt district is laterally parallel, and the fusion joining disk mounting interface in welding panel is laterally parallel.Also comprise the bus-type fibre bundle that is made up of many parallel optical fiber pigtails, the two ends of each bar optical fiber pigtail are provided with corresponding mark, and the mark of each optical fiber pigtail is different.
The invention has the beneficial effects as follows:
Bus-type tail optical fiber route is provided with, and the interface is succinctly orderly, is convenient on the one hand safeguard, has solved the problem that the dust accretions that optical fiber causes in a jumble in the prior art can't be cleared up simultaneously.
All fusion joining disks are all at lower box.All optical cables that externally connect like this after opening stripping, directly get into fusion joining disk and are fused into and hold adapter;
All optical splitters are installed in casing top, can dispose as required;
Optical splitter adopts the module of boxlike.Different colours or colour circle can be divided in every tail optical fiber end, with sign tail optical fiber number, are convenient to management maintenance;
Because every optical splitter all has label, tail optical fiber that sign is arranged, and under the huge situation of customer volume, also is convenient to distinguish;
Cancelled the adapter of prior art, the volume of optical splitter is less, and density can be accomplished very high.
