Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:

referring to fig. 1, the heavy buried armored fiber optic cable includes a cable core and an armor layer disposed outside the cable core.

The cable core comprises a central reinforced core 11, a plurality of optical fiber wires and a filling rope 1, wherein the optical fiber wires and the filling rope 1 are arranged around the central reinforced core 11, all the optical fiber wires and the filling rope 1 are stranded on the central reinforced core 11, and a cable core filler 10 is arranged between the armor layer and the central reinforced core.

The optical fiber line comprises an optical fiber 7, the optical fiber 7 is directly placed in a loose tube 9, and a tube filler 8 is arranged between the loose tube 9 and the optical fiber 7.

The armor is including wrapping the plastic-coated aluminum strip 5 in the cable core outside the outside cladding of plastic-coated aluminum strip 5 has polyethylene inner protective sheath 4 the outside cladding of protective sheath 4 has water blocking cover 3 in the polyethylene the outside of water blocking cover 3 has chromium plating plastic-coated steel band 2 around the outside cladding of chromium plating plastic-coated steel band 2 has polyethylene outer protective sheath 6.

The more detailed description is as follows:

in the embodiment, the central reinforced core 11 is formed by heating and curing a plurality of glass fibers compounded with a resin layer, specifically, the central reinforced core 11 is formed by immersing a plurality of glass fibers into a resin oligomer or prepolymer, so that the resin completely coats the glass fibers, and then heating and curing the resin to obtain the resin compound central reinforced core, and the central reinforced core combines the tensile property of the glass fibers and the bending toughness of the resin, so that the optical cable has good tensile strength, lateral pressure resistance, twisting resistance and flexibility. The central reinforced core is very important for the design of the optical cable, on one hand, the central reinforced core is used for supporting the whole optical cable and plays an important role in the tensile strength, the lateral pressure resistance and the torsion resistance of the optical cable, and on the other hand, the central reinforced core also determines the flexibility of the optical cable. The filling rope 1 is a tensile element, so that the optical cable has higher tensile strength, and simultaneously, when the optical cable is impacted by external force and pressed laterally, the filling rope and the outer sheath can play a role in buffering, so that the optical fiber is protected, and the service life of the optical cable is prolonged. In this embodiment, the optical fiber 7 is any one of a bare fiber, a coated fiber and a tight-buffered fiber, and has excellent bending properties, thereby facilitating the laying of an optical cable. The sleeve filler 8 is a flexible filler added for preventing the optical fiber 7 from shaking in the loose sleeve 9 to cause unsmooth light path transmission, and plays a role in supporting and protecting the optical fiber. The cable core filler 10 is a flexible filler, and plays a role in supporting and buffering.

The plastic-coated aluminum strip 5 can be bonded with a polyethylene protective sleeve to prevent the polyethylene protective sleeve from being bonded with a loose tube, and the plastic-coated aluminum strip 5 has the characteristics of strong weather resistance, high bending resistance and the like. The water blocking sleeve 3 is formed by pressing multiple water blocking materials, has excellent flexibility, waterproofness and corrosion resistance, and can be used in an outdoor environment with severe conditions. The chrome-plated plastic-coated steel belt 2 is made of a stainless steel belt and is high in corrosion resistance. The polyethylene outer protective sleeve 6 can effectively prevent the optical cable from being corroded, and enables the optical cable to have the advantages of being convenient to lay and the like.
