Technical field
The present invention relates to a kind of cable connection method, especially relate to a kind of cable connection method based on optical cable clamp.
Background technology
Shanghai Telecom city light net is fast-developing, and the coverage rate of optical-fiber network is more and more wider.The requirement of the construction of optical cable (technique that continues and flow process) also improves constantly.The reply develop rapidly, traditional all circles' technique and flow process can not be satisfied the demand.
In the laying construction of existing optical cable, for aerial optical cable, no matter be circular optical cable or ribbon optical fiber cable, the structure of its clamping device is more complicated all, and weight greatly, not easy to operate.Because the diameter dimension of optical cable is less, directly use hand to carry out the clamping operation, not only require great effort, take a lot of work, efficient is low, labour intensity is large, and, if undue force is easily to the optical cable injury in the construction.So far, there is no a kind of clamping device of convenient construction operation in order to the laying construction of optical cable.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of cable connection method based on optical cable clamp for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of cable connection method based on optical cable clamp is characterized in that, may further comprise the steps:
1) selects the identical naked fibre of many optical cables of mode field diameter;
2) apply the naked fibre of cable of giving out light;
3) place of continuing between two naked fibres of optical cable adopts optical cable clamp to fix;
4) fiber end face of the every naked fibre of optical cable cut by the fiber end face cutter;
5) by heat sealing machine the place of continuing is carried out welding, on one side in fusion process the connecting loss of the fusion point of welding OTDR (optical time domain reflectometer) test on one side, carry out again welding to undesirable.
Described applying in the naked fine process of cable of giving out light, its tractive force is added on the reinforcement of optical cable, tractive force be no more than that optical cable allows 80%, moment maximum drawbar pull be no more than 100%.
Fixedly optical cable is used when continuing for described optical cable clamp, and it is a pair of, about each one, be fixed on the both sides of worktable, each optical cable clamp is provided with two planes of stationary work-table table top and fixing optical cable V-type groove.
The axis inclination angle of described fiber end face is less than 1 degree.
Compared with prior art, the present invention has the following advantages:
1, optimizes cable connection flow process, reduction fiber optic splicing loss;
2, reduce the probability of optical fiber damaged in the optical cable construction;
3, convenient and simple for operation.
Embodiment
The present invention is described in detail below in conjunction with specific embodiment.
Embodiment
A kind of cable connection method based on optical cable clamp may further comprise the steps:
1) selects the identical naked fibre of many optical cables of mode field diameter;
2) apply the naked fibre of cable of giving out light;
3) place of continuing between two naked fibres of optical cable adopts optical cable clamp to fix;
4) fiber end face of the every naked fibre of optical cable cut by the fiber end face cutter;
5) by heat sealing machine the place of continuing is carried out welding, on one side in fusion process the connecting loss of the fusion point of welding OTDR (optical time domain reflectometer) test on one side, carry out again welding to undesirable.
Select the identical naked fibre of many optical cables of mode field diameter:
For same batch optical fiber, its mode field diameter is identical, and optical fiber is after certain point disconnects, and the mode field diameter between two ends can be considered unanimously, thereby can make mode field diameter that the impact of fiber optic splicing loss is dropped to minimum level in this cut-off point welding.So require optical cable manufacturer with same batch naked fibre, cable length is on request produced continuously, serial number and distinguish A, B end on every dish must not the number of jumping.Must be by number during laying optical cable sequentially lay along the route of determining, and guarantee that the B end of shroud optical cable will link to each other with the A end of a rear dish optical cable, can be in the cut-off point welding thereby guarantee when continuing, and make the splice loss, splice attenuation value reach minimum.
Apply the naked fibre of cable of giving out light:
In the fiber optic cable facility worker, forbid optical cable to play ringlet and folding, distortion, the optical cable of 3km must the above construction of 80 people, and 4km must the above construction of 100 people, and is equipped with 6～8 intercoms; The other cable laying method of " front walk heel, take on the optical cable ", the generation that can effectively prevent from beating back of the body button.Tractive force be no more than that optical cable allows 80%, moment maximum drawbar pull be no more than 100%, tractive force should be added on the reinforcement of optical cable.Applying the cable of giving out light should be strictly by the optical cable construction requirement, thereby minimally reduces the probability of optical fiber damaged in the optical cable construction, and the splice loss, splice attenuation of avoiding the fiber cores damaged to cause increases.
Selecting veteran fibre junction personnel continues
Now welding is the automatic welding of heat sealing machine mostly, but the personnel's that continue level directly affects the size of connecting loss.The personnel of continuing should continue in strict accordance with the fused fiber splice process chart, and in the fusion process welding on one side on one side with the connecting loss of OTDR test fusion point.Undesirable again welding, the point larger to the splice loss, splice attenuation value, the welding number of times is advisable with 3～4 times repeatedly, when the multifiber splice loss, splice attenuation is all large, can wipes out one section optical cable and again open the cable welding.
The optical cable that continues should carry out in clean and tidy environment
Forbid to operate in the open in the environment of many dirt and humidity, cable connection position and instrument, material should keep clean, and must not allow fibre-optical splice make moist, and the optical fiber of preparing cutting must clean, and dirt must not be arranged.After the cutting optical fiber must not be in air open-assembly time long, especially in the environment of many dirt humidity.
Select the high fiber end face cutter of precision to prepare fiber end face
The quality of fiber end face directly has influence on the splice loss, splice attenuation size, and the optical fiber of cutting should be smooth minute surface, without burr, and N/D.The axis inclination angle of fiber end face should be less than 1 degree, and high-precision fiber end face cutter not only improves the success ratio of fiber cut, also can improve the quality of fiber end face.This to OTDR test not fusion point (being the OTDR test blindspot) and optical fiber maintenance and rush to repair particularly important.
The correct use of heat sealing machine
The function of heat sealing machine is exactly that two fused fiber splices are arrived together, also is the important measures that reduce optical fiber splice loss so correctly use heat sealing machine.According to fiber type splicing parameter, pre-arcing electric current, time and main discharge current, main discharge time etc. are set with holding water, and in use with after using in time remove dust in dust, particularly anchor clamps, each minute surface and the V-shaped groove in the heat sealing machine and the removal at the broken end of optical fiber.Before each the use heat sealing machine was placed ten five minutes in the welding environment at least, particularly placing the place larger with the environment for use difference (such as winter indoor and outdoor), according to ambient conditions such as at that time air pressure, temperature, humidity, reset sparking voltage and the discharge position of heat sealing machine, and make the adjustment such as V-shaped groove driver resets.
