Description

A kind of method of attachment of telecommunication optical fiber

[technical field]

The present invention relates to a kind of method of attachment of telecommunication optical fiber, refer in particular to the fast method of the interface welding connection that contains many telecommunication optical fiber core prints that is applicable to indoor and outdoor.

[background technology]

High speed development along with the communication technology; The telecommunication optical fiber of long distance is laid and is become inevitable; The welding mode is adopted in the connection of optical fiber generally speaking, and fused fiber splice is through hot melting way butt joint optical fiber, and the optical fiber that is about to after optical cable is moved adopts hot melting way to dock with the optical fiber of another root optical cable.This technology is one of basic technology of fiber optic communication field, and the quality direct relation of fused fiber splice the reliability of optical fiber communication, this shows the importance of fused fiber splice; But up to now; The nearly all fused fiber splice work in the whole communications field all is to accomplish having no under the condition of special-purpose workbench, and fused fiber splice work great majority are to carry out out of doors, or even is quite carrying out under the rugged environment; Like this; The workmen can only rely on tool box or other harder objects to accomplish fused fiber splice work as temporary transient workbench, owing to there is not seat, the tradesman can only couchant work; An optical cable inside generally includes the multifiber core print; Such as by existing working method, generally robbing the logical optical cable fusion process that includes 96 optical fiber core prints needs two hours, and working together wastes time and energy but efficient is not high often.

In addition; The twisting of optical cable increases several fibre core losses or is disconnected fine; Optical cable receives the external force effect to cause inner one or the disconnected core of several fibre core, and human factor is dug the optical cable outer jacket to hinder and made son pipe or fibre core fracture etc., and existing fused fiber splice mode all inconvenience is carried out fault handling.

Therefore, in the prior art, there is the defective that awaits improving in the recovery technique after optical fiber breaks off.

[summary of the invention]

In view of this; The present invention provides a kind of method of attachment of telecommunication optical fiber, can improve the logical speed of robbing of the diffusing shape optical fiber of big core number, robs logical efficient when optical fiber breaks off and can promote one times; And the optical fiber connecting portion of robbing after leading to receives the external factor interference less, and difficult the repetition damaged.

For reaching said purpose, the method for attachment of a kind of telecommunication optical fiber of the present invention comprises:

1. the multifiber that separates the broken end position of the multi-core fiber that has broken off;

2. lay one section intact optical fiber ribbon cable in the centre position at said broken end position;

3. peel off the ribbon fiber in sheath, cleaning broken end position and the said centre position of the ribbon fiber that the centre position lays; Said method of attachment further comprises by the chromatogram of optical fiber carries out layout to the multifiber at said broken end position of separating; To compile with the optical fiber of chromatogram is one; With insulating tape said optical fiber with chromatogram is adhesively fixed, the fibre ribbon of the said same chromatogram of finishing respectively with the optical fiber welding mutually of the corresponding chromatogram of the ribbon fiber in said centre position.

Further, said each optical fiber twice that are adhesively fixed with chromatogram.

Further, the fiber reel that said welding is good is loaded onto fused fiber splice disk cover plate after putting shockproof sponge in the fused fiber splice dish.

Beneficial effect of the present invention is; Turn parts into the whole, be transformed into the welding of the higher ribbon fiber of efficient to the welding of the shape optical fiber that looses, welding efficient can promote one times; The optical cable of the diffusing shape optical fiber more than several 48 cores of big core is robbed logical speed especially can be accelerated; And the optical fiber of warp-knit tape is bonding by bindings such as adhesive tapes, can reduce because of receiving the external force effect to the influence that inside of optical fibre brought, and compares with the technical scheme in existing this field to have outstanding substantive distinguishing features and obvious improvement.

Below in conjunction with accompanying drawing and preferred embodiment the present invention is described further.

[description of drawings]

[embodiment]

The fiber count of traditional multi-core fiber is by the kind and the quantity decision of optical data waiting for transmission.In order to make multi-core fiber, need arrange to requisite number purpose optical fiber, the optical fiber of arranging with the coating working procedure processing again, thus form multiple sheath.Because it is banded that the profile of this multi-core fiber is, therefore be called as " fibre ribbon ".

The flow chart of steps of the method for attachment of a kind of telecommunication optical fiber as shown in Figure 1, the method for attachment of a kind of telecommunication optical fiber of the present invention is following:

1. the multifiber that separates the broken end position of the multi-core fiber that has broken off; And suitably wipe the waterproofing unction that adheres on the every optical fiber; It is noted that waterproofing unction all do not wipe, need on every optical fiber, to keep some and makes every optical fiber surface have certain viscosity.

2. carry out layout by the chromatogram of optical fiber, compiling with the optical fiber of chromatogram is one, owing to leave waterproofing unction in advance from the teeth outwards, and not easily separated after therefore finishing with the optical fiber of chromatogram.

3. respectively that some programmed optical fiber with chromatogram are stretching, the plastic adhesive tape with insulation is adhesively fixed then, and best mode is with the fixing twice plastic band of the fibre ribbon of chromatogram to each.

Compiled the ribbon fiber basically identical of braid in diffusing shape optical fiber apperance and the factory of band.As long as whole process is about 5 minutes.

4. lay one section intact optical fiber ribbon cable in the centre position of the breakpoint of the optical fiber that breaks off; Be the method for operating of available existing tape splicing shape optical fiber then; Peel off sheath, cleaning breakpoint and the centre position ribbon fiber of the ribbon fiber that the centre position lays, and the different chromatogram fibre ribbons of braid respectively with the optical fiber welding mutually of the corresponding chromatogram of this centre position ribbon fiber.

5. the fiber reel that welding is good is loaded onto fused fiber splice disk cover plate after putting shockproof sponge in the fused fiber splice dish.
