[0054] Furthermore, the aforementioned anti-biting and anti-pecking introduction optical cable is characterized in that: a reinforcement strip is also provided inside the bottom wall, the reinforcement strip is located above and below the optical communication component, and the reinforcement strip is connected to the reinforcement member as a whole.

[0055] The reinforcing strips and reinforcing members are connected as a whole, actually forming a frame, which can better resist external lateral pressure, improve mechanical properties, and of course also improve tensile strength, impact resistance, etc.

[0056] The above-mentioned introduction optical cable that can resist biting and pecking is characterized in that the side wall body of the second butterfly-shaped unit has a reinforcement piece, the bottom wall body has an optical communication component, and the optical communication component has at least one optical fiber.

[0058] The reinforcing strips and reinforcing parts are connected as a whole, actually forming a frame, which can better resist external lateral pressure, improve mechanical properties, and of course also improve tensile strength, impact resistance, etc.

[0059] Furthermore, the present application describes an introduction optical cable that is resistant to chewing and pecking, comprising a main cable core and an outer sheath, wherein the outer sheath is covered over the outside of the main cable core, and is characterized in that: the main cable core is composed of two sub-cable cores stacked up and down or arranged side by side left and right, the sub-cable core is any of the sub-cable cores described above, the cross-section of the outer edge of the main cable core is rectangular, and the cross-section of the outer edge of the outer sheath is rectangular.

[0060] Furthermore, the present application describes an introduction optical cable that is resistant to chewing and pecking, comprising a main cable core and an outer sheath, wherein the outer sheath is covered over the main cable core, and is characterized in that: the main cable core is formed by a plurality of sub-cable cores stacked up and down; or, the main cable core is composed of a plurality of sub-cable cores arranged side by side left and right; or, the main cable core is composed of a plurality of stacked sub-cable cores, and the stacked sub-cable core is formed by a plurality of sub-cable cores stacked up and down, and a plurality of stacked sub-cable cores are arranged side by side left and right; the sub-cable core is any of the sub-cable cores described above, the cross-section of the outer edge of the main cable core is a rectangle, and the cross-section of the outer edge of the outer sheath is a rectangle.

[0061] In the present application, the sub-cable core can be used separately, and they are tightly fitted together to form an integrated structure. They cannot be separated without applying sufficient force, so they can be easily introduced into the house. Two specifications of butterfly units, namely the first butterfly unit and the second butterfly unit, can be introduced into the same house, which greatly improves its flexibility of use. Users do not need to purchase optical fiber connectors separately, and can use the existing technology to match with related optical equipment, thereby improving versatility. At the same time, at least two optical access channels can be provided to meet the user's subsequent capacity expansion and multiple functions. The electrical communication components can be connected as telephone lines, control lines, etc., which makes up for the defect that a single butterfly introduction unit cannot be used for weak current transmission when it is connected in the prior art. Of course, in the present application, when the first butterfly unit does not have a reinforcement bar, the reinforcement member can also be used as a weak current transmission line if it is made of metal; similarly, when the second butterfly unit does not have a reinforcement bar, the reinforcement member can also be used as a weak current transmission line if it is made of metal; thus improving the transmission performance and route of weak current.

[0063] In the present application, the outer sheath can be steel, iron, aluminum, copper, alloy, glass fiber reinforced plastic, etc. In this case, the optical cable further improves the performance of anti-chewing and pecking; of course, in fact, the outer sheath can also be plastic in the prior art. When used, it is laid in a wiring device such as a steel pipe with a square cross-section and a wiring trough. Since the wiring device itself has high strength and hardness, the optical cable also has the performance of anti-chewing and pecking; the hard outer sheath or wiring device makes it impossible for animals such as mice to gnaw and no longer gnaw, so it achieves an anti-chewing and pecking effect. Similarly, ants cannot bite it either, so it plays an anti-biting role. In addition, the hard material makes it impossible for birds to peck it, so it plays an anti-pecking role.

[0064] The present application is very suitable for indoor and outdoor installation due to its tight and compact structure. Moreover, since it has at least two butterfly-shaped units, compared with the butterfly-shaped optical cable introduction in the prior art, it has more tensile force elements and thus has greater tensile force resistance, making it suitable for self-supporting installation, thereby increasing the scope of application.

[0065] In the present application, the sub-cable cores of two different types of butterfly-shaped units can be processed and formed at one time. During production, the two butterfly-shaped units are embedded in each other and the electrical communication components are placed. At the same time, they can be extruded or covered with an outer sheath on the outside, which makes production very convenient and fast.

[0066] In the present application, the side wall, the bottom wall, the side wall body and the bottom wall body are all made of plastic.

[0067] In the present application, the materials of the first reinforcement member, the first reinforcement strip, the second reinforcement strip, the third reinforcement member, the first reinforcement member, the first reinforcement strip, the second reinforcement strip, and the third reinforcement member can be steel, iron, aluminum, copper, glass fiber reinforced plastic rod, aramid yarn, etc., and different materials mentioned above can also be used.

[0068] In the present application, the material of the bonding layer is plastic, and the optical fiber is a single-mode or multi-mode optical fiber in the prior art, which can be a glass optical fiber or a plastic optical fiber, and can be a solid optical fiber or a hollow optical fiber.

[0069] In the present application, the material of the conductor is copper or aluminum or copper alloy or aluminum alloy, and the material of the insulating layer is plastic.

[0070] In the present application, it is preferred that the cross section of the outer edge of the insulating layer is rectangular, and similarly the cross section of the outer edge of the conductor is also rectangular, and the colors of the insulating layers of the two electrical communication components are different, so that they can be easily distinguished.

[0071] In the present application, the first butterfly unit is an integrated structure, and the second butterfly unit is also an integrated structure.

[0072] The present application has the following main beneficial technical effects: easy to manufacture, simple and compact structure, better mechanical properties, better resistance to chewing and pecking, suitable for application in various occasions, and suitable for self-supporting laying.

[0073] The present application can be used as an intelligent sensor or intelligent sensing element; since it can transmit voice and images, it can also be used as a physical sensor, such as a voice sensor or an image sensor; since it transmits optical signals through the principle of total reflection, it can also be used as a distance sensor; the optical fiber in the present application is an optical waveguide itself, so it can be used as an optical waveguide, such as an array optical waveguide or a diffraction optical waveguide; the present application can also be used in the field of optical computing, as part of optical chip computing, in the fields of optical computing, optical computing, and optical network computing.

[0074] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limiting the present invention.
