Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, a preferred embodiment of the present invention provides a pressure-resistant and rat-proof butterfly-shaped optical cable, which includes an optical fiber 4 for transmitting optical signals. The optical fiber 4 may be provided as a single mode optical fiber 4 or a multimode optical fiber 4 as needed.

Inner sheath 3, the outer rectangle structure that is of inner sheath 3, cavity 5 is placed to inside seting up of inner sheath 3, and optic fibre 4 sets up in placing cavity 5. The outer sheath 1 is coated on the outer side of the inner sheath 3, and the inner sheath 3 is located in the middle of the inner part of the outer sheath 1. Preferably, the placement cavity 5 is provided as a hexagonal cavity, the placement cavity 5 being centrally provided with respect to the inner sheath 3. Preferably, the outer sheath 1 is made of LSZH (Low smoke zero halogen) or PVC (polyvinyl chloride) or PE (polyethylene).

The inner sheath 3 is made of FRP. Preferably, the volume of the placement cavity 5 is larger than the sum of the volumes of all the optical fibers 4 placed in the placement cavity 5. From this, can make and have certain activity space at the many optic fibre 4 of placing in placing cavity 5, when inner sheath 3 receives outside extrusion deformation, lie in and place the optic fibre 4 in cavity 5, can remove to other vacant spaces when receiving the extrusion, and then avoid the extrusion. This can improve the pressure resistance of the cable.

In the present invention, preferably, the inner sheath 3 and the outer sheath 1 are formed by extrusion.

In order to achieve the rat-proof effect, the cable in the related art is wrapped and wrapped with a glass fiber tape outside the optical fiber 4 to form a cable core, and then a PE sheath is added outside the cable. The method needs to involve two process methods of winding and extrusion molding, so that the processing process is more complicated and the working procedures are more, and further the preparation cost is increased. In this embodiment, the inner sheath 3 and the outer sheath 1 may be integrally formed and coated outside the optical fiber 4 by an extrusion molding process, so that the processing process and the number of processes may be reduced, and the manufacturing cost may be reduced.

And the reinforcing part 2 is arranged in the outer sheath 1 in a penetrating way. Preferably, the reinforcing members 2 are provided in two, and the centers of the two reinforcing members 2 and the center of the inner sheath 3 are on the same straight line. Preferably, the material of the reinforcing member 2 is phosphated steel wire or galvanized steel wire or FRP or KFRP (aramid fiber). The optical fiber 4 can be prevented from being excessively bent by providing the reinforcing member 2, and the problem of attenuation of the optical fiber 4 can be avoided as much as possible. Therefore, the two reinforcing members 2 are disposed in a direction in which the cable is easily bent during the laying and installation.
