10. A framework; 11. a framework groove; 20. a reinforcing center piece; 30. a sheath; 40. an optical fiber; 50. a water resistant layer; 60. an outer support member.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a skeleton OPGW optical cable includes a skeleton 10, a reinforcing central part 20 and a sheath 30 covering the outer end of the skeleton 10, the reinforcing central part 20 is disposed at the center of the skeleton 10 to enhance the central support of the optical cable, and skeleton grooves 11 are disposed on the inner end surface of the skeleton 10, the skeleton grooves 11 are disposed at the inner end surface of the skeleton 10 at intervals to increase the internal storage amount, and optical fibers 40 are disposed in the skeleton grooves 11, and the optical fibers 40 are disposed in the skeleton 10 in an overlapping manner to increase the capacity of the optical fibers 40 of the optical cable, and a water blocking layer 50 is disposed between the skeleton 10 and the sheath 30, so that the water blocking layer 50 can achieve a good waterproof effect, and an outer layer support 60 disposed in an annular array is disposed on the outer side of the sheath 30, so that good support and stability can be achieved, and the internal optical fibers 40 are prevented from being damaged.

The optical fibers 40 are optical fiber ribbons or micro-tube optical fibers, which can be conveniently overlapped in the optical cable, and the number of the optical fibers 40 inside the optical cable is increased.

The reinforcing central member 20 is a steel strand reinforcing member, has a good supporting force, and plays a role in stabilizing and supporting.

Wherein, outer support piece 60 is the aluminium-clad steel wire, possesses good corrosion resisting property, long service life and the characteristics of being convenient for maintain, and the protection that can be fine is inside not impaired.

Wherein, the water-proof layer 50 is water-proof yarn or water-proof powder, can effectually play waterproof effect, avoids inside to be affected by the tide and uses.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention。
