A kind of miniature high intensity resists the processing technology of micro-bend stainless steel tube armored optical cable, comprising:
By optical fiber built-in in stainless steel micro pipe, and factice for filling inside it, obtain optical cable core；
According to the size of optical cable core, the fiber that optical cable core simultaneously again can be closely coupled can be wrapped by, which designing, glues
Close layer；
Fiber adhesive layer is wrapped on optical cable core, then passes it through extruding machine and carries out extruding for oversheath, is squeezed
Finished cable after system.
Preferably, further includes: the finished cable after extruding is cooled down, and passes through traction machine travel to take-up stand drum
Take-up.
It can be seen via above technical scheme that compared with prior art, the present disclosure provides a kind of miniature high intensity
Resist micro-bend stainless steel tube armored optical cable and its processing technology, cable configuration provided by the invention covers fiber adhesive layer in stainless steel
Outside micro-pipe loose tube fiber, fit closely integrally, with light weight, environmental resistance is excellent, bending radius is small, soft, tension is strong
The features such as degree height, anti-side pressure function admirable, the shortcomings that stainless steel micro pipe is easy bending is compensated for, while also in stainless steel micro pipe
It has fitted closely one layer of high strength fibre outside to be protected, the superposition of wing-rooms on either side of a one-story house excellent properties, so that the cable configuration has stainless steel
Pipe and the respective advantage of high strength fibre, give full play to the performance of two kinds of materials.
