Description
Technical field
The utility model relates to the fast rapid-result end assembly of a kind of high-performance optical fiber, is specifically related to the fast rapid-result end assembly of various model built-in type optical fiber.
Background technology
At present, along with the develop rapidly of Fibre Optical Communication Technology, the PON access technology has become the main solution that global FTTH (Fiber to the home) popularizes in an all-round way.Yet, insert at this last kilometer and to install, how to accomplish to register one's residence that cost is low, easy for installation, quickness and high efficiency, it is very crucial possessing good optical property, high unfailing performance simultaneously again.
Install for the access of FTTH (Fiber to the home), traditional optical fiber fusion welding technology is because its cost is high, receive the restriction in place, installation personnel to need professional training etc. former thereby can't obtain large-area popularization when installing.The fast rapid-result end of optical fiber assembly has become the optimal selection scheme that present FTTH inserts with its advantage such as easy for installation, quick, efficient.
Common in existing fast rapid-result end assembly have through type (also claiming direct insertion or dry type) and a built-in type.The fast rapid-result end assembly of through type is owing to the restriction of prior art, and performance index are stable inadequately, can't satisfy fiber-to-the-home connection requirement.The fast rapid-result end assembly of general built-in type; Be a pre-buried optical fiber in the ceramic insertion core endoporus, an end forms the termination of docking with normal connector with ceramic insertion core behind grinding and polishing, and the other end then exposes certain-length and guarantees that end face is smooth; Then bared end optical fiber is installed in the V-type groove; The V-type groove is equipped with corresponding optical fiber and overlays piece and be used for fixing outer butt joint of going into optical fiber and pre-buried optical fiber, in the V-type groove, presets the coupling gel during butt joint in advance, also subsidiary simultaneously optical cable locking device.When constructing at the scene, with realizing being connected fast through V-type groove and pre-buried fiber alignment after the fiber cut.But there are a lot of problems in this scheme, as: 1), fracture easily in the whole process flow, cause scrapping of product because pre-buried optical fiber one end is exposed at outward outside the lock pin; 2) precision of V-type groove making is not high, and butt joint optical fiber can't be realized being coaxial docking and cause Insertion Loss bigger than normal; 3) the V-type groove becomes independent accessory with lock pin, and is general fixing through gummed, and when temperature variation, reliability of products can not get guaranteeing; 4) be on active service for a long time easy ageing, distortion of product material; 5) the assembled on site one-time success rate is low, and about 10% need carry out the secondary assembling.
The utility model content
The purpose of the utility model provides the fast rapid-result end assembly of a kind of high-performance optical fiber; Utilize the high precision inner-pore butt joint of ceramic insertion core to replace existing plastics V-type groove; It not only can accomplish easy for installation, quick, efficient and the cost of registering one's residence is low, possesses good optical property and high reliability simultaneously again.The utility model has solved various inefficacies or the bad problem that fast at present rapid-result end assembly exists fully.
The technical solution of the utility model is: the fast rapid-result end assembly of a kind of high-performance optical fiber; Comprise the lock pin body and be positioned at the endoporus of lock pin body; Said lock pin body exposes endoporus formation one butt joint platform after eliminating the part cylinder; Pre-buried optical fiber achieves a butt joint with docking the endoporus place of optical fiber at said docking platform, docking platform be provided with one be used to compress 2 fiber alignment points compressing structure.
In this programme, pre-buried optical fiber achieves a butt joint in endoporus with docking optical fiber, avoids pre-buried optical fiber to expose and causes the defective of frangible; In addition, docking platform and the lock pin body material that is formed in one, manufacture craft is more simple, and reliability of products is better; Utilize the tube bank effect of compressing structure and endoporus self, the Insertion Loss that dislocation that has occurred easily when having solved the prior art fiber alignment or inclination angle problem cause is bigger than normal.
Further, said compressing structure comprises and is used to the lock ring cover that compresses the briquetting of fiber alignment point and be used for fixing briquetting.
Further, said briquetting is provided with a groove, is used to preset protection optical fiber and matees gel, and the coupling gel is volatilization or loss when long-time the use, presets the coupling gel and can replenish at any time, has guaranteed that interface has enough coupling gels when repeatedly penetrating optical fiber simultaneously.
Be equipped with the optical fiber entrance hole on the incoming end of said lock pin body and briquetting.Particularly, said lock pin body one end is conventional flexible jumper termination, and the other end is provided with the V-type entrance hole, makes things convenient for optical fiber to penetrate the endoporus from its importing.
The utility model uses ceramic insertion core endoporus docking point to replace the advantage of butt joint in the existing V groove to be:
One, the fast rapid-result end assembly of high-performance optical fiber possesses good optical property and high reliability.
Two, in whole making flow process, pre-buried fiber optic protection is difficult for being damaged in the inside of lock pin body, has guaranteed its quality and cost in factory process.And present optical fiber quick connector all to be pre-buried optical fiber expose, when assembling, fracture easily, it is impaired or be stained with booty to occur fiber end face simultaneously, causes butt joint to be lost efficacy.
Three, two fiber alignments point is the C type groove that high-precision ceramic insertion core endoporus forms, and the lock pin endoporus is accomplished 1um easily with interior tolerance grade, make two fiber alignments after loss less than 0.1dB.
Four, the lock pin endoporus at fiber alignment place is indeformable under the external force extruding, does not lose efficacy.And the V-type groove that uses organic material is under the extruding of external force extruding or self-contained spring, and easy deformation lost efficacy.
Five, in the briquetting groove, preset enough coupling gels, repeatedly can replenish the coupling gel after butt joint or long-time the military service.
Six, the assembled on site one-time success rate is high, superior performance.
