The utility model provides the reinforced stainless steel optical fiber loose tube optical cable of a kind of braided wires, comprise sheath, braided wires and stainless steel optical fiber loose tube, wherein, the lateral surface that described braided wires is stranded in the shape of a spiral, be wound around, be close to described stainless steel optical fiber loose tube, described braided wires has four at least and evenly arranges around the circumferential interval of described stainless steel optical fiber loose tube, and described sheath wraps up described braided wires, stainless steel optical fiber loose tube.
As further improvement of the utility model, the twisting pitch of described braided wires is greater than the diameter 40 times of described optical cable.
As further improvement of the utility model, described braided wires has the six roots of sensation at least and evenly arranges around the circumferential interval of described stainless steel optical fiber loose tube.
As further improvement of the utility model, described braided wires has the six roots of sensation and around the setting of 60 degree, the circumferential interval of described stainless steel optical fiber loose tube.
As further improvement of the utility model, in described stainless steel optical fiber loose tube, be filled with ointment and optical fiber.
As further improvement of the utility model, the diameter of described stranded guiding principle silk is less than the diameter of described stainless steel optical fiber loose tube.
The beneficial effects of the utility model are: by braided wires to improve the bend resistance performance of optical cable, improve the tensile strength of optical cable, under the characteristic that performance is better than conventional overhead and duct optical cable, keep less material consumption and lower production cost, reduce overall weight greatly.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the reinforced stainless steel optical fiber loose tube optical cable of a kind of braided wires of the utility model.
Fig. 2 is the structural representation of the reinforced stainless steel optical fiber loose tube optical cable of a kind of braided wires of the utility model.
Embodiment
