Description
The present invention relates to a kind of cable connection methods, more particularly, to a kind of cable connection side based on optical cable clamp
Method.
Shanghai Telecom city light net is fast-developing, and the covering surface of optical-fiber network is more and more wider.Optical cable construction (subsequent process and
Flow) requirement be also continuously improved.Reply rapid development, traditional all circles' technique and flow have been unable to meet needs.
In the laying construction of existing optical cable, for aerial optical cable, either circular optical cable or ribbon optical fiber cable, work is clamped
The structure of tool is all more complicated, and weight is not big, easy to operate.Since the diameter dimension of optical cable is smaller, directly pressed from both sides using hand
Hold operation, not only arduously, take a lot of work, efficiency is low, labor intensity is big, if moreover, construction in undue force easily optical cable is caused to damage.
So far, it there is no and a kind of facilitate the clamping device of construction operation to the laying construction of optical cable.
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind to be clamped based on optical cable
The cable connection method of device.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of cable connection method based on optical cable clamp, which is characterized in that include the following steps：
1) the identical more optical cable naked fibres of mode field diameter are selected；
2) cable naked fibre of giving out light is applied；
3) it is fixed using optical cable clamp at the connecting between two optical cable naked fibres；
4) fiber end face of every optical cable naked fibre is cut by fiber end face cutter；
5) by heat sealing machine to carrying out welding at connecting, in fusion process while welding using OTDR, (optical time domain is anti-
Penetrate instrument) test fusion point connecting loss, to undesirable progress welding again.
During the deposited cable naked fibre of giving out light, tractive force is added on the reinforcer of optical cable, and tractive force is no more than optical cable
80% allowed, moment maximum drawbar pull are no more than 100%.
The optical cable clamp is to be fixed when connecting used in optical cable, and for a pair, each one of left and right is fixed on workbench
Both sides, each optical cable clamp is equipped with two planes of stationary work-table table top and fixed optical cable V-groove.
The axis inclination angle of the fiber end face is less than 1 degree.
Compared with prior art, the present invention has the following advantages：
1, optimization cable connection flow, reduction fiber optic splicing loss；
2, the probability that optical fiber is damaged in optical cable construction is reduced；
3, convenient and simple for operation.
With reference to specific embodiment, the present invention is described in detail.
Embodiment
A kind of cable connection method based on optical cable clamp, includes the following steps：
1) the identical more optical cable naked fibres of mode field diameter are selected；
2) cable naked fibre of giving out light is applied；
3) it is fixed using optical cable clamp at the connecting between two optical cable naked fibres；
4) fiber end face of every optical cable naked fibre is cut by fiber end face cutter；
5) by heat sealing machine to carrying out welding at connecting, in fusion process while welding using OTDR, (optical time domain is anti-
Penetrate instrument) test fusion point connecting loss, to undesirable progress welding again.
Select the identical more optical cable naked fibres of mode field diameter：
For with a batch of optical fiber, mode field diameter is identical, for optical fiber after certain point disconnects, the mode field diameter between both ends can
It is considered as unanimously, thus influence of the mode field diameter to fiber optic splicing loss can be made to be preferably minimized degree in this cut-off point welding.So
It is required that optical cable manufacturer is with a batch of naked fibre, cable length continuous production as required, serial number is simultaneously on every disk
The end A, B is distinguished, it must not number-skipping.It must be laid by number along determining routing order when laying optical cable, and ensure the ends B of shroud optical cable
To be connected with the ends A of latter disk optical cable, can be in cut-off point welding when to ensure to connect, and splice loss, splice attenuation value is made to reach minimum.
Apply cable naked fibre of giving out light：
In fiber optic cable facility work, optical cable is forbidden to play ringlet and folding, distortion, the optical cable of 3km more than 80 people must construct, 4km
It more than 100 people must construct, and be equipped with 6~8 intercoms；In addition the cable laying method of " preceding walk heel, shoulder on optical cable ", Neng Gouyou
Prevent from beating to effect the generation of back buckle.Tractive force is no more than 80% that optical cable allows, and moment maximum drawbar pull is no more than 100%, leads
Gravitation should be added on the reinforcer of optical cable.Applying cable of giving out light should be strictly by optical cable construction requirement, to which minimally reduces optical cable
The probability that optical fiber is damaged in construction, splice loss, splice attenuation caused by avoiding fiber cores from being damaged increase.
Veteran fibre junction personnel are selected to connect
Present welding is the automatic welding of heat sealing machine mostly, but the level for connecting personnel directly affects the size of connecting loss.
Connecting personnel should connect in strict accordance with fused fiber splice process flow chart, and answer in fusion process and used while welding
OTDR tests the connecting loss of fusion point.It is undesirable should welding again, the point larger to splice loss, splice attenuation value, welding repeatedly
Number is advisable with 3~4 times, when multifiber splice loss, splice attenuation is all larger, can be wiped out one section of optical cable and be opened cable welding again.
Splicing cables should carry out in clean and tidy environment
Forbid the outdoor operation in more dirt and the environment of humidity, cable connection position and tool, material that should keep cleaning, no
Fibre-optical splice must be allowed to make moist, preparing the optical fiber of cutting must clean, and there must not be dirt.Optical fiber must not expose in air after cutting
Overlong time, especially in the environment of more dirt humidity.
Fiber end face cutter with high accuracy is selected to prepare fiber end face
The quality of fiber end face directly influences splice loss, splice attenuation size, and the optical fiber of cutting should be smooth minute surface, impulse- free robustness,
N/D.The axis inclination angle of fiber end face should be less than 1 degree, high-precision fiber end face cutter not only improve fiber cut at
Power can also improve the quality of fiber end face.This to OTDR test not fusion point (i.e. OTDR test blindspots) and optical fiber
It safeguards and repairs and is particularly important.
Heat sealing machine it is proper use of
The function of heat sealing machine is exactly that two fused fiber splices are connect to together so proper use of heat sealing machine is also reduction optical fiber
The important measures of continuous loss.Splicing parameter, pre-arcing electric current, time and main discharge electricity are set with holding water according to fiber type
Stream, main discharge time etc., and remove the dust in heat sealing machine, especially fixture, each minute surface in time in use and after use
With the removal of dust and optical fiber powder in V-shaped slot.Heat sealing machine should be made to place at least 15 in welding environment before each use
Minute, especially place with the larger place of use environment difference (such as winter interior with outdoor), according at that time air pressure,
The ambient conditions such as temperature, humidity, reset the discharge voltage and discharge position of heat sealing machine, and V-shaped slot driver is made to reset
Deng adjustment.
