(c) first to cover upper flexible protective casing again on welding optic fibre or the second Loose tube to welding optic fibre；
(d) first end face processing is carried out respectively to welding optic fibre to welding optic fibre and second, finally strip a segment length
Then coat carries out welding；
(e) elasticity for a segment length being coated centered on fusion point using optical fiber coating equipment at once after the completion of welding is ultraviolet
Solidification glue；
(f) the flexible protective casing of preparatory set at one end is moved at elastic uv-curable glue, carries out heat using heating furnace
Contracting is fixed.
Specifically, first is of the same race or xenogenesis diameter optical fiber to welding optic fibre to welding optic fibre and second.
Preferably, the flexible protective casing is double-layer structure, and inside and outside layer is radially fixed.
Preferably, described in above-mentioned steps (a) first to welding optic fibre and second to welding optic fibre to welding end point
Not Yu Liu the optical fiber of 23mm~25mm do not cover Loose tube.
Preferably, the length of flexible protective casing is 59mm~60mm in above-mentioned steps (c).
Preferably, first end face is carried out respectively to welding optic fibre to welding optic fibre and second described in above-mentioned steps (d)
Processing, it is 12mm~14mm that final coat, which strips length, then carries out welding.
Preferably, it is coated centered on fusion point using optical fiber coating equipment at once after the completion of welding in above-mentioned steps (e)
One segment length is the elastic uv-curable glue of 32mm~35mm.
The guard method of fused fiber splice by adopting the above technical scheme, has the advantages that compared with prior art
(1) Global Macros are done after fused fiber splice, avoids extraneous factor and optical fiber is directly affected；After the completion of welding at once
Coat consolidation process is done to the optical fiber for having stripped coat, effectively prevents stripping at the optical fiber of coat that there are residual gas
Bubble, has evaded granule foreign or pollutant inside protection sleeve pipe and has directly contacted bare fibre；It is ultraviolet solid that elasticity is carried out at fusion point
Change glue and the dual reinforcing of flexible protective casing, increase the mechanical strength and bending resistance of fusion point, is conducive to remaining fibre and stores；
