Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber transmission technology, and more specifically, to an integral polymer optical fiber transmission system. Background Technology
[0002] Monolithic polymer transmission fiber is a type of optical fiber that uses polymer as the main material for optical signal transmission. Unlike some optical fibers that are composed of multiple different parts, monolithic polymer transmission fiber is a continuous whole in structure, without obvious splicing or layering. This ensures that the light is more stable during transmission and reduces light scattering and loss caused by structural discontinuities.
[0003] A search revealed that Chinese Patent CN215067444U discloses a novel transmission optical fiber. By setting up a support body, the structural strength of the novel transmission optical fiber can be improved, preventing excessive bending deformation and improving its straightness, thereby enhancing communication performance. Furthermore, when the novel transmission optical fiber is subjected to an external force along its axial direction, causing both the first and second cladding layers to break, the fiber body can still extend to a certain length without being immediately torn apart, thus improving the fiber's resistance to damage.
[0004] When the aforementioned transmission optical fiber is used, the optical fiber line includes at least a first cladding layer, a second cladding layer, and an optical fiber body. However, it is inconvenient to adjust the optical properties of the optical fiber. Dispersion will cause different frequency components of the optical signal to propagate at different speeds during transmission, resulting in signal pulse broadening and limiting the transmission distance and transmission rate. For example, in high-speed, long-distance optical communication systems, the inability to effectively adjust dispersion may cause severe signal distortion over short distances, limiting the performance improvement of the communication system. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an integral polymer transmission optical fiber, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an integral polymer transmission optical fiber, comprising a sheath and a core, wherein the core is located inside the sheath, a cladding is fixedly fitted on the core, the cladding has multiple air holes, and a reinforcing assembly is provided between the cladding and the sheath. The reinforcing assembly includes a first reinforcing sleeve, a second reinforcing sleeve, multiple retaining sleeves, and multiple retaining plates. The first reinforcing sleeve is fixedly installed inside the sheath, and the second reinforcing sleeve is fixedly fitted on the outside of the cladding. The multiple retaining sleeves are respectively fixedly installed on the opposite side of the first and second reinforcing sleeves, and the two ends of the multiple retaining plates extend into the interior of the multiple retaining sleeves.
[0007] Furthermore, multiple protective layers are fixedly connected between the first reinforcing sleeve and the second reinforcing sleeve, and all of the protective layers are polyimide components.
[0008] Furthermore, the first reinforcing sleeve, the second reinforcing sleeve, the multiple sleeves, and the multiple plates are all made of polyvinyl chloride.
[0009] Furthermore, the diameter of the pores gradually increases from the inner side to the outer side of the cladding.
[0010] Furthermore, the sheath is a polyurethane component.
[0011] It can be seen that the above technical solution has extremely high flexibility and elasticity, can withstand large stretching and bending deformation without breaking, has excellent wear resistance and strong abrasion resistance, and can effectively protect optical fibers from damage in frequent movement or friction environments.
[0012] Furthermore, the fiber core is a quartz glass component.
[0013] It can be seen that the above technical solutions have advantages such as high purity, good transparency, strong chemical stability, and low coefficient of thermal expansion, which can transmit optical signals well. In addition, doping silica optical fiber with an appropriate amount of germanium can improve the refractive index of the optical fiber and reduce CH bond-related losses.
[0014] Furthermore, the cladding layer is a silicone rubber component.
[0015] It can be seen that the above technical solutions can transmit relatively stably within the fiber core, reduce scattering and refraction losses caused by uneven cladding optical properties, and help improve the transmission quality and signal integrity of optical fibers.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] 1. By setting a cladding, this utility model can ensure better optical uniformity to a certain extent, so that when light propagates in the optical fiber, it can be transmitted more stably in the fiber core, reducing scattering and refraction losses caused by uneven optical performance of the cladding. The presence of pores can reduce the effective refractive index of the cladding, and as the pores gradually increase in size from the inside to the outside, the propagation speed and mode characteristics of light in the cladding can be changed by changing the size distribution of the pores, thereby controlling the dispersion characteristics of the optical fiber. The structure is simple and easy to adjust the optical characteristics of the optical fiber.
[0018] 2. This utility model can protect the fiber core and cladding through multiple protective layers. The protective layers have excellent high temperature resistance and can maintain stable physical and chemical properties in high temperature environments. At the same time, they also have good mechanical strength and wear resistance, which can enhance the tensile and wear resistance of optical fibers. The overall strength can be further improved through the first reinforcing sleeve, the second reinforcing sleeve, multiple ferrules and multiple clamping plates. The structure is simple and has a long service life. Attached Figure Description

A cladding 3 is fixedly fitted on the fiber core 2, and multiple air holes 6 are opened on the cladding 3. A reinforcing component 4 is provided between the cladding 3 and the sheath 1. The reinforcing component 4 includes a first reinforcing sleeve 401, a second reinforcing sleeve 402, multiple retainers 403, and multiple retaining plates 404. The first reinforcing sleeve 401 is fixedly installed inside the sheath 1, and the second reinforcing sleeve 402 is fixedly fitted on the outside of the cladding 3. The multiple retainers 403 are respectively fixedly installed on the opposite side of the first reinforcing sleeve 401 and the second reinforcing sleeve 402. The two ends of the multiple retaining plates 404 extend into the interior of the multiple retainers 403.
[0026] Furthermore, multiple protective layers 5 are fixedly connected between the first reinforcing sleeve 401 and the second reinforcing sleeve 402, and the multiple protective layers 5 are all polyimide components. The first reinforcing sleeve 401, the second reinforcing sleeve 402, the multiple sleeves 403 and the multiple plates 404 are all polyvinyl chloride components.
[0027] The fiber core 2 and cladding 3 are protected by multiple protective layers 5. The protective layers 5 have excellent high temperature resistance and can maintain stable physical and chemical properties in high temperature environments. They also have good mechanical strength and wear resistance, which can enhance the tensile and wear resistance of the optical fiber. The overall strength can be further improved by the first reinforcing sleeve 401, the second reinforcing sleeve 402, multiple ferrules 403 and multiple clamping plates 404. The structure is simple and has a long service life.
[0028] Furthermore, the diameter of the pores 6 gradually increases from the inside to the outside of the cladding 3, the sheath 1 is a polyurethane component, the fiber core 2 is a quartz glass component, and the cladding 3 is a silicone rubber component.
[0029] The usage method of this embodiment is as follows:
[0030] In use, the sheath 1 possesses extremely high flexibility and elasticity, capable of withstanding significant tensile and bending deformation without breakage. It exhibits excellent wear resistance and strong abrasion resistance, effectively protecting the optical fiber from damage during frequent movement or friction. The core 2 boasts high purity, good transparency, strong chemical stability, and a low coefficient of thermal expansion, enabling excellent transmission of optical signals. Furthermore, the appropriate doping of germanium into the silica fiber increases its refractive index while reducing CH bond-related losses. The cladding 3 ensures good optical uniformity to a certain extent, allowing light to propagate stably within the core and reducing scattering caused by uneven cladding optical properties. The reduction of refraction and scattering losses helps improve the transmission quality and signal integrity of optical fibers. The presence of pores 6 can reduce the effective refractive index of cladding 3. As pores 6 gradually increase in size from the inside to the outside, the effective refractive index of cladding 3 exhibits a gradient change. This gradual refractive index distribution allows for better control of mode confinement and optical field distribution when light propagates in the optical fiber. This helps reduce optical signal leakage and scattering losses, thereby improving the transmission efficiency and performance of the optical fiber. By changing the size distribution of pores 6, the propagation speed and mode characteristics of light in cladding 3 can be altered, thereby regulating the dispersion characteristics of the optical fiber. The structure is simple and facilitates the adjustment of the optical properties of the optical fiber.
