It is further characterized in that:

a filling rope is arranged in the aluminum strip wrapping range, the outer diameter of the filling rope is the same as that of the sleeve, and the filling rope and the sleeve are uniformly distributed on the periphery of the central reinforcing part;

a framework is arranged in the aluminum strip wrapping range, the framework is in a hub shape, a bone groove corresponding to the sleeve and the filling rope is formed in the outer wall of the framework, the outer diameter of the framework is smaller than the inner diameter of the aluminum strip, the inner diameter of the bone groove is larger than the outer diameters of the sleeve and the filling rope, a through hole is formed in the center of the framework, and the central reinforcing piece penetrates through the through hole;

the outer wall of the inner sheath is provided with a groove corresponding to the steel wire, and the inner sheath and the groove are integrally formed;

the inner sheath is made of polyethylene and is bonded to the outer edge wall of the aluminum strip;

the outer sheath is made of polyethylene, and the steel wire is a galvanized steel wire.

The beneficial effects of the utility model are that, it is equipped with inner sheath, steel wire, non-woven fabrics from inside to outside in proper order between aluminium strip and oversheath to formed stronger mechanical properties protection, can prevent under the various circumstances, this optical cable protection architecture is destroyed and leads to the possibility that water gets into the optical cable, can satisfy directly burying, wait a plurality of environments of laying under water, has better use spreading value.
