Description

Communication optical cable

Technical Field

The utility model relates to an optical cable technical field especially relates to a communication optical cable.

Background

With the continuous development of network construction, the optical fiber with high transmission rate and long distance is used as a data transmission medium in the comprehensive wiring system, and the utilization rate is also continuously improved.

Because the utilization rate of the optical cable is continuously increased, in order to not influence the attractiveness, a plurality of optical cables are buried underground, the underground wiring, particularly the urban underground wiring is more and more complicated, the optical cables are easily damaged during construction, the cables are broken, the use of users is influenced, and resources are wasted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a to the not enough of prior art existence, the communication optical cable that can prevent the cutting.

In order to solve the technical problem of appeasing, the technical scheme of the utility model is that: a communication optical cable comprises an optical cable core arranged at the innermost layer of the optical cable, wherein the outer side of the optical cable core is respectively provided with a pressure-resistant layer, a beam tube, heat insulation foam, a semiconductor shielding layer, an optical cable sheath and a cutting-resistant layer; the cutting-proof layer is composed of a plurality of spliced cutting-proof blocks, each cutting-proof block comprises a circular convex block and a circular concave block, a convex subdivision is arranged on each circular convex block, a groove matched with the convex subdivision is arranged on each circular concave block, and a steel wire mesh formed by numerous small circular rings in a penetrating and weaving mode is fixedly connected between each circular convex block and each circular concave block.

Preferably: the circumference of the beam tube is coated with a layer of reinforcing piece, and the reinforcing piece is formed by winding aramid yarns around the beam tube.

Preferably: and a waterproof layer is arranged outside the optical cable sheath, and a gap between the optical cable sheath and the waterproof layer 6 is filled with mica glass fiber and waterproof glue.

The utility model has the advantages that: the utility model discloses an add in the optical cable sheath outside and prevent cutting the layer, can effectively avoid through this preventing cutting the layer and can lead to the destruction to the optical cable because the reason accident of construction to have thermal-insulated, fire prevention, shielding electromagnetic function.
