Description

Technical Field

[0001] This invention relates to the field of optical cable technology, and in particular to an ultra-low loss, high-density optical cable with a butterfly-shaped unit. Background Technology

[0002] With the rapid development of communication technology, society's performance requirements for optical cables are constantly increasing. In today's information age, data traffic is experiencing explosive growth, and the demand for various information transmissions is increasing daily. Whether it's the large-scale construction of 5G communication networks, laying massive lines to achieve high-speed, wide-coverage communication services, or the continuous expansion of data centers to cope with the ever-increasing data storage and processing tasks, there is an urgent need for optical cables to have higher transmission capacity to carry more information data; lower signal loss to ensure that information remains stable and clear during long-distance transmission; and a more compact structure to adapt to complex and diverse laying environments and save space resources. However, when facing these high-performance demands, the inherent defects of traditional optical cables are gradually becoming apparent, revealing many limitations. The fiber core density of traditional optical cables is relatively low, a characteristic that makes it difficult to achieve efficient integration of a large number of optical fibers within a limited space. This directly results in the inability to meet the actual needs of continuous expansion of communication lines in space-constrained application scenarios such as indoor integrated cabling and narrow duct laying, which greatly restricts the expansion and upgrading of communication networks in these scenarios and makes it difficult to adapt to the urgent requirements of modern communication technology for high-density fiber optic integration. Summary of the Invention

[0003] In view of this, the present invention provides an ultra-low loss high-density optical cable with butterfly units. Through a structural design employing tightly arranged butterfly units, it can accommodate more fiber cores than traditional optical cables within the same outer diameter, not only increasing the transmission capacity of the optical cable but also reducing the space required for cabling. Furthermore, the tension rods and insertion slots effectively aggregate and constrain adjacent butterfly reinforcements, ensuring that each butterfly reinforcement is tightly aligned, improving the overall structural compactness, and preventing loosening or misalignment due to excessively high butterfly reinforcement density. This ensures the stability and rationality of the butterfly reinforcement layout. The material selection and structural design of the reinforcing rods and protective sleeves in the butterfly units endow the optical cable with excellent bending, compressive, and tensile resistance. This allows the optical cable to better adapt to various complex environmental conditions during laying and use, reducing the risk of damage caused by external forces and improving the cable's reliability and service life. By adding reinforcing ribs inside the buffer layer, the tensile and bending resistance of the buffer layer is further improved, enhancing the overall structural stability of the optical cable. The patterned treatment on the steel strip surface increases the friction between the armor layer and the outer sheath, preventing the outer sheath from sliding on the armor layer surface and improving the overall integrity of the optical cable structure. The raised strips and balls on the outer sheath surface not only increase the friction between the optical cable and the laying environment, preventing slippage during laying and facilitating cable fixation and installation, but also improve the bending resistance of the outer sheath, reducing the stress on the outer sheath when the optical cable bends.

[0004] This invention provides an ultra-low loss high-density optical cable with a butterfly unit, specifically including: a butterfly-shaped reinforcing member;

[0005] The butterfly-shaped reinforcing member has a core hole in the middle, a protective sleeve inside the core hole, an optical cable core installed inside the protective sleeve, and reinforcing rods on both sides of the optical cable core, which are installed at both ends of the butterfly-shaped reinforcing member.

[0006] The butterfly-shaped reinforcement is arranged horizontally. A fitting groove is provided in the middle of the upper and lower ends of the butterfly-shaped reinforcement. Two sets of vertical butterfly-shaped reinforcements are tightly fitted in the fitting groove. Two sets of horizontal butterfly-shaped reinforcements are provided in the fitting grooves on both sides of the two sets of vertical butterfly-shaped reinforcements. At the same time, two more sets of vertical butterfly-shaped reinforcements are provided vertically between the two sets of horizontal butterfly-shaped reinforcements. One end of the additional butterfly-shaped reinforcement has a fitting groove that is tightly fitted to both ends of the middle butterfly-shaped reinforcement.

[0007] The butterfly-shaped reinforcing member is provided in nine groups. There is a notch between the nine groups of butterfly-shaped reinforcing members. The butterfly-shaped reinforcing members adjacent to the notch are provided with insertion slots. Insertion blocks are fitted into the notches. Connecting protrusions are fixedly connected to the four sides of the insertion blocks. A tension rod is fixedly connected to the end of the connecting protrusion. The tension rod is fitted into the insertion slot.

[0008] Furthermore, the protective sleeve is made of polyvinyl chloride, and the reinforcing rod is made of aramid fiber.

[0009] Furthermore, the outer side of the butterfly-shaped reinforcing member is provided with a water-blocking layer, the interior of which is filled with a waterproof filler, and the waterproof filler contains a cable rope.

[0010] Furthermore, the waterproof filler is petroleum paste, and the water-blocking layer is made of non-woven fabric impregnated with a water-blocking agent.

[0011] Furthermore, a buffer layer is provided on the outside of the water-blocking layer, and an interlocking groove is provided inside the buffer layer, with reinforcing ribs installed inside the interlocking groove.

[0012] Furthermore, the buffer layer is typically made of polyethylene foam or rubber, with its reinforcing ribs made of high-strength fiber materials or metal wires.

[0013] Furthermore, a moisture-proof layer is provided on the outside of the buffer layer. The moisture-proof layer is an aluminum-plastic composite strip, which is usually made of aluminum foil and plastic film. An armor layer is provided on the outside of the moisture-proof layer. The armor layer is made of steel strip and has diamond patterns pressed on its outside.

[0014] Furthermore, the outer side of the armor layer is provided with an outer sheath, the inner sidewall of the outer sheath is provided with a diamond-shaped groove to increase friction with the diamond pattern, and the outer side of the outer sheath is provided with a connecting protrusion in a ring array, and an anti-slip protrusion is fixedly connected to the connecting protrusion.

[0015] Furthermore, the outer sheath is made of polyethylene (PE) or polyvinyl chloride (PVC).

[0016] The ultra-low loss, high-density optical cable with butterfly-shaped units provided by this invention has the following beneficial effects.

[0017] 1. By adopting a structural design with tightly arranged butterfly units, more fiber cores can be accommodated than in traditional optical cables within the same outer diameter. This not only increases the transmission capacity of the optical cable but also reduces the space required for cabling. At the same time, with the setting of tension rods and insertion slots, effective aggregation constraints can be formed on adjacent butterfly reinforcements. This ensures that each butterfly reinforcement can be closely aligned, improving the overall structural compactness, and also avoids loosening and misalignment due to excessively high distribution density of butterfly reinforcements. This ensures the stability and rationality of the butterfly reinforcement layout.

[0018] 2. The material selection and structural design of the reinforcing rods and protective sleeves in the butterfly unit give the optical cable excellent resistance to bending, compression, and tension. This allows the optical cable to better adapt to various complex environmental conditions during laying and use, reducing the risk of damage caused by external forces and improving the reliability and service life of the optical cable.

[0019] 3. By incorporating reinforcing ribs within the buffer layer, its tensile and bending resistance is further enhanced, improving the overall structural stability of the optical cable. Patterning the steel strip surface increases friction between the armor layer and the outer sheath, preventing the outer sheath from slipping on the armor layer surface and improving the overall structural integrity of the optical cable. Raised strips and balls on the outer sheath surface not only increase friction between the optical cable and the laying environment, preventing slippage during installation and facilitating cable fixation and installation, but also improve the bending resistance of the outer sheath, reducing stress on the outer sheath when the cable bends.

[0048] Example 1: Please refer to Figures 1 to 8 :

[0049] This invention proposes an ultra-low loss high-density optical cable with a butterfly unit, comprising: a butterfly reinforcement 1;

[0050] The butterfly-shaped reinforcing member 1 has a core hole 101 in the middle, a protective sleeve 1011 inside the core hole 101, an optical cable core 1012 installed inside the protective sleeve 1011, and reinforcing rods 1013 on both sides of the optical cable core 1012. The reinforcing rods 1013 are installed at both ends of the butterfly-shaped reinforcing member 1.

[0051] The butterfly-shaped reinforcing member 1 is arranged horizontally. A fitting groove 102 is provided in the middle of the upper and lower ends of the butterfly-shaped reinforcing member 1. Two sets of vertical butterfly-shaped reinforcing members 1 are tightly fitted in the fitting groove 102. Two sets of horizontal butterfly-shaped reinforcing members 1 are provided in the fitting groove 102 on both sides of the two sets of vertical butterfly-shaped reinforcing members 1. At the same time, two more sets of vertical butterfly-shaped reinforcing members 1 are vertically arranged between the two sets of horizontal butterfly-shaped reinforcing members 1. The fitting groove 102 on one side of the additional butterfly-shaped reinforcing member 1 is tightly fitted with the two ends of the middle butterfly-shaped reinforcing member 1.

[0052] Nine sets of butterfly-shaped reinforcing members 1 are provided. A notch 103 is provided between the nine sets of butterfly-shaped reinforcing members 1. An insertion slot 1031 is opened on the butterfly-shaped reinforcing member 1 adjacent to the notch 103. An insertion block 104 is fitted into the notch 103. A connecting protrusion 1041 is fixedly connected to the four sides of the insertion block 104. A tension rod 1042 is fixedly connected to the end of the connecting protrusion 1041. The tension rod 1042 is fitted into the insertion slot 1031.

[0053] The protective sleeve 1011 is made of polyvinyl chloride, and the reinforcing rod 1013 is made of aramid fiber.

[0054] By adopting a structural design with tightly arranged butterfly units, the optical cable of the present invention can accommodate more fiber cores than traditional optical cables with the same outer diameter. The protective sleeve 1011 in the butterfly reinforcement 1 is made of polyvinyl chloride (PVC) material, which has good flexibility and insulation performance, and can effectively protect the internal optical cable core 1012 and the reinforcing rod 1013. The reinforcing rod 1013 is made of aramid fiber, and its high strength and lightweight characteristics can provide sufficient mechanical support for the butterfly reinforcement 1. By means of the coordinated setting of the tension rod 1042 and the insertion slot 1031, an effective aggregation constraint can be formed on the adjacent butterfly reinforcement 1, which not only ensures that each butterfly reinforcement 1 can be closely close together, improving the compactness of the overall structure, but also avoids the situation of loose misalignment due to the excessive distribution density of the butterfly reinforcement 1, thereby ensuring the stability and rationality of the layout of the butterfly reinforcement 1.

[0055] Example 2: Based on Example 1, wherein, as Figure 1 and Figure 2 As shown, the outer side of the butterfly-shaped reinforcing member 1 is provided with a water-blocking layer 3, and the interior of the water-blocking layer 3 is filled with a waterproof filler 2, and the waterproof filler 2 is provided with a cable 201.

[0056] The waterproof filler 2 is petroleum paste, and the water-blocking layer 3 is made of non-woven fabric impregnated with a water-blocking agent.

[0057] The main function of the waterproof filler 2 is to fill the gap between the optical cable core 1012 and the water-blocking layer 3, preventing moisture from entering through the gaps in the optical cable core 1012. The water-blocking layer 3 further enhances the waterproof effect.

[0058] Example 3: Based on Examples 1 and 2, wherein, as shown in Example 3... Figures 6 to 8 As shown, a buffer layer 4 is provided on the outside of the water-blocking layer 3, and an interlocking groove 401 is provided inside the buffer layer 4. A reinforcing rib 4011 is installed inside the interlocking groove 401.

[0059] The buffer layer 4 is typically made of polyethylene foam or rubber, and its reinforcing ribs 4011 are made of high-strength fiber material or metal wire.

[0060] A moisture-proof layer 5 is provided on the outside of the buffer layer 4. The moisture-proof layer 5 is an aluminum-plastic composite strip, which is usually made of aluminum foil and plastic film. An armor layer 6 is provided on the outside of the moisture-proof layer 5. The armor layer 6 is made of steel strip, and a diamond pattern 601 is pressed on the outside of the armor layer 6.

[0061] The outer side of the armor layer 6 is provided with an outer sheath 7. The inner side wall of the outer sheath 7 is provided with a diamond-shaped groove 701 that increases friction with the diamond pattern 601. The outer side of the outer sheath 7 is arranged in a ring with connecting protrusions 702. Anti-slip protrusions 7021 are fixedly connected to the connecting protrusions 702.

[0062] The outer sheath 7 is made of polyethylene (PE) or polyvinyl chloride (PVC).

[0063] The buffer layer 4 is designed to absorb external impacts and vibrations, reducing their impact on the cable core and preventing fiber breakage or performance degradation due to external impacts. The reinforcing ribs 4011 further enhance the tensile and bending resistance of the buffer layer 4. The moisture-proof layer 5 prevents external moisture intrusion. The armor layer 6 withstands significant mechanical impacts, pressure, and tension, protecting the internal optical cable core 1012 from damage and ensuring structural stability and reliable performance in complex laying and usage environments. The combination of the diamond pattern 601 and diamond groove 701 increases the friction between the armor layer 6 and the outer sheath 7, preventing the outer sheath 7 from sliding on the surface of the armor layer 6 and improving the overall integrity of the optical cable structure. The connecting convex strip 702 enhances the bending resistance of the outer sheath 7, reducing stress on the outer sheath when the optical cable bends. The anti-slip convex ball 7021 primarily increases the friction between the outer sheath 7 and the external environment, preventing movement.

[0064] The specific usage and function of this embodiment: In this invention, a protective sleeve 1011 is fitted onto the outer side of the optical cable core 1012, and then the optical cable core 1012 and the reinforcing rod 1013 are installed into the butterfly-shaped reinforcing member 1 to form a complete butterfly-shaped unit. Nine sets of butterfly-shaped reinforcing members 1 are assembled together sequentially according to the designed arrangement, and then inserted into the slots 103 between the butterfly-shaped reinforcing members 1 by inserting blocks 104, forming an effective aggregation constraint. This ensures that each butterfly-shaped reinforcing member 1 can be tightly close together, improving the overall structural compactness, and also avoids loosening and misalignment due to excessively high distribution density of the butterfly-shaped reinforcing members 1, thereby protecting the butterfly-shaped reinforcing members 1. The stability and rationality of the layout are ensured, and then a water-blocking layer 3 is set on its exterior. Then, waterproof filler 2 is filled between the water-blocking layer 3 and the combined cable core. A buffer layer 4 is formed by extruding polyethylene foam material on its exterior, and reinforcing ribs 4011 are simultaneously embedded in the buffer layer 4 to improve its tensile and bending resistance. A moisture-proof layer 5 is laid on the outside of the buffer layer 4, and then a patterned steel strip is wrapped around the outside of the moisture-proof layer 5 to form an armor layer 6. Finally, an outer sheath 7 is installed on the outside of the armor layer 6 to complete the optical cable manufacturing. This optical cable, through its tightly arranged butterfly unit structure design, can accommodate more fiber cores than traditional optical cables under the same outer diameter size, which not only improves the transmission capacity of the optical cable but also reduces the space required for cabling.
