Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Title in figure corresponding to sequence number is as follows:
Oversheath 1, metal hose 2, waterstop 3, central reinforce member 4, optical cable subelement 5, microbeam pipe 6, fibre bundle 7, water blocking yarn 8, glass fibre layer 9.
Embodiment
A kind of superhigh intensity large core number multipurpose optical fiber optical cable, see Fig. 1: its from outer in the cross-sectional structure that is arranged in order be oversheath 1, metal hose 2, waterstop 3, be stranding cable core in the inner chamber of waterstop 3, waterstop 3 is wrapped in the outside of stranding cable core, reinforcement 4 centered by the center of stranding cable core, the outer ring surface of central reinforce member 4 is evenly equipped with at least three optical cable subelements 5, every root optical cable subelement 5 comprises outside microbeam pipe 6, the fibre bundle 7 of center, and the water blocking yarn 8 between the inwall and the outer wall of fibre bundle 7 of microbeam pipe 6, water blocking yarn 8 specification 250dtex takes up space very little, thus cable size can be made little, lightweight and block-water effect is good.
Glass fibre layer 9 is filled with between the inner ring surface of oversheath 1 and the outer ring surface of metal hose 2; itself and metal hose 2 play the function of dual mouse bite preventing simultaneously; again can increase the tensile resistance of optical fiber cable simultaneously; and preventing metal hose 2 to swipe oversheath inwall, protection oversheath 1 does not ftracture because of scratch when bearing pressure.
Metal hose 2 is specially flange-connection stainless steel metal flexible pipe, flange-connection stainless steel metal flexible pipe armouring is in oversheath 1, it has excellent flexibility, repeated flex, flexibility, corrosion resistance, heat-resisting quantity, resistance to bending, tensile property and lateral pressure resistant, the soft resistance to compression of optical fiber cable can be ensured, be easy to stay dish, be more conducive to built on stilts laying;
Central reinforce member 4 is specially FRP central reinforce member, and it not only can bear tensile resistance, and can stablize optical cable subelement, supports optical cable and bears more powerful pressure;
