Abstract
The invention relates to the information transmission medium optical fibers, in particular to a fiber spicing method, which comprises the end face preparation step, the optical fiber fusion step and the fiber coiling step. The invention is characterized in that the specific fiber coiling steps start from the middle part, followed by both sides, namely, heat-shrinkable casings are placed in a fixed tank one by one, and then the remaining fibers at both sides are treated. The method mainly solves the disadvantages that the fiber coiling operation in the existing fiber spicing method is not conducive to the protection of the optical contacts, so as to further to improve the fiber spicing quality and facilitate the smoothness of information transmission of the fiber network.
Description
Technical field
The present invention relates to the connecting method of information transmission medium light, particularly a kind of light.
Background technology
Optical Access Network (OAN) is the Access Network that adopts optical fiber transmission technique, the i.e. communication system of all or part of employing Optical Fiber Transmission between Local Exchange and the user.Advantages such as optical fiber has that broadband, long-distance transmissions ability are strong, good confidentiality, antijamming capability are strong are the main implementation technique of following Access Network.
And fibre junction is an elaboration, and it helps to set up a fiber optic network that information transmission is unobstructed, loss of signal is less.Existing fibre junction mainly is made of three links such as end face preparation, welding, dish fibres.Wherein, the fine mode of operation of dish mainly is fine since end dish, the stationary heat draw, and then handle the surplus fibre of opposite side.The advantage of this method is: can select the copper pipe riding position flexibly according to the surplus fine length of a side, and convenient, fast, can avoid occurring sharp turn, ringlet phenomenon, but its shortcoming is to be unfavorable for protecting the optical fiber contact, so just cause the continued access poor effect easily.
Summary of the invention
The object of the present invention is to provide a kind of optical fibre connecting method, mainly solve the shortcoming that is unfavorable for protecting the optical fiber contact after the fine operation of dish in the existing fiber connecting method, further improved the quality of fibre junction, the information transmission that helps fiber optic network is unobstructed.
For addressing the above problem, the present invention is achieved in that
A kind of optical fibre connecting method, it comprises fine three job steps of preparation, fused fiber splice and dish of end face, it is characterized in that: the fine concrete operations step of dish is the first intermediate and then both sides, promptly earlier the sleeve pipe after the pyrocondensation is positioned in the pickup groove one by one, and then handles the surplus fibre in both sides.
Described optical fibre connecting method, the preparation that it is characterized in that described end face comprise that further stripping covers, cleans and cut link.
Described optical fibre connecting method is characterized in that the cleaning of naked fibre comprising following operation steps:
A: whether the coat that observation optical fiber divests part all divests, residual as if having, and should divest again;
B: cotton is torn into the smooth fan-shaped fritter of aspect, is stained with a little alcohol, be converted into V-arrangement, clamp the optical fiber that covers with stripping, the fine axially wiping of frontlighting.
Described optical fibre connecting method is characterized in that the process for stripping that described optical fiber is coated with surface layer is: clutch optical fiber with finger earlier, make it into horizontal, reveal length and be as the criterion with 5cm, surplus fibre bends between the third finger, little finger naturally, with the increase dynamics; Fiber stripping pincers should be vertical with optical fiber, and the top certain angle that slopes inwardly blocks the optical fiber right hand gently with jaw then, exerts oneself thereupon, and the fine axially horizontal sliding of frontlighting is gone out.
Embodiment
The invention provides a kind of optical fibre connecting method, concrete steps are as follows:
Step 1: the preparation of end face; The preparation of fiber end face comprises that stripping covers, cleans and cut this several links.Qualified fiber end face is the necessary condition of welding, and the end face quality directly has influence on the welding quality.
(1) optical fiber is coated with divesting of surface layer
Optical fiber is coated with divesting of surface layer, flat, steady, the fast three word fiber stripping methods of GPRS." put down ", promptly hold fibre and will put down.Left hand thumb and forefinger are clutched optical fiber, make it into horizontal, reveal length and be as the criterion with 5cm, surplus fibre bends between nameless, little finger naturally, with the increase dynamics, prevents to skid." surely ", i.e. fiber stripping pincers will be held surely.It is fast that " soon " is that fiber stripping is wanted, and the fiber stripping pincers should be vertical with optical fiber, and the top certain angle that slopes inwardly blocks the optical fiber right hand gently with jaw then, exerts oneself thereupon, and the fine axially horizontal sliding of frontlighting is gone out, and whole process is natural and tripping, accomplishs without any letup.
(2) cleaning of naked fibre, should operate by the two following steps:
1) observes the coat that optical fiber divests part and whether all divest,, should divest again if having residually.If any the coat that minute quantity is difficult for divesting, available silk tops is stained with an amount of alcohol, on one side dipping, progressively wipe on one side.
2) cotton is torn into the smooth fan-shaped fritter of aspect, be stained with a little alcohol (refer to mutually pinch do not have overflow be advisable with two), be converted into " V " shape, clamp the optical fiber that covers with stripping, once success is striven in the fine axially wiping of frontlighting, after using 2～3 times, a cotton in time change, to use different parts and the aspect of cotton at every turn, can improve the cotton utilization factor like this, prevent to visit twice fine pollution again.
(3) cutting of naked fibre
The cutting of naked fibre is a most key part in the fiber end face preparation, and accurate, good cutting knife is the basis, and working specification strict, science is to guarantee.
Step 2: fused fiber splice
Fused fiber splice is the key link of the work of continuing, so the science operation is very necessary in high-performance heat sealing machine and the fusion process.
According to the material and the type of optical fiber, set main molten electric current of best fritting and key parameters such as time and the optical fiber amount of sending into before the welding.Also should in time clean heat sealing machine " V " shape groove, electrode, object lens, welding chamber etc. in the fusion process, at any time observe and have or not bubble, meticulous, thick excessively, bad phenomenon such as void is molten, separation in the welding, note OTDR test instrumentation tracking and monitoring result, in time analyze the reason that produces above-mentioned bad phenomenon, take corresponding improvement measures.As empty molten phenomenon repeatedly occurring, should check whether the material of two optical fiber of welding, model mate, whether cutting knife and heat sealing machine be by contamination by dust, and inspection anodizing situation, if all no problem then should suitably improve welding current.
Step 3: dish is fine
The dish fibre is a special kind of skill, also is an art.The dish method for fiber of science can make that optical fiber is rationally distributed, added losses are little, stand the test of time and rugged surroundings, can avoid the disconnected fine phenomenon that causes because of extruding.
The concrete operations step of the inventive method mid-game fibre is: the first intermediate and then both sides promptly is positioned over the sleeve pipe after the pyrocondensation in the pickup groove one by one earlier, and then handles the surplus fibre in both sides.Advantage: help protecting the optical fiber contact, avoid coiling the infringement that fibre may cause.
Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
