Description

Technical Field

[0001] This utility model relates to the field of optical fiber technology, and in particular to a jumper fixing device with optical power attenuation and beam splitting functions. Background Technology

[0002] In fiber laser and amplifier applications, attenuation and splitting of optical signals transmitted through optical fibers are typically achieved by connecting a fixed attenuator or adjustable attenuator to a conventional flange-fixed jumper, followed by a multi-stage coupler or PLC. Figure 1 As shown;

[0003] This approach has the following drawbacks: Low integration: It requires independent configuration of attenuators and couplers, resulting in large size and complex wiring; High operational risk: Manual adjustment of attenuators can easily lead to optical power overload and damage to test equipment; Limited splitting function: Traditional couplers only support a fixed splitting ratio, which cannot meet the needs of parallel testing of multiple devices; High connection loss: Insufficient jumper connection accuracy leads to a decrease in optical power transmission efficiency.

[0004] Therefore, it is necessary to provide a jumper fixing device with optical power attenuation and beam splitting functions to effectively solve or partially solve the above problems. Utility Model Content

The first fixing mechanism and the second fixing mechanism are respectively connected to the first Z-axis moving mechanism and the second Z-axis moving mechanism. The first fixing mechanism and the second fixing mechanism are used to fix the input jumper and the output jumper, respectively. By adjusting the first Y-axis moving mechanism, the second Y-axis moving mechanism, the first Z-axis moving mechanism, and the second Z-axis moving mechanism, the input jumper and the output jumper fixed to the first fixing mechanism and the second fixing mechanism are horizontally aligned. The output jumper is a multi-core beam splitting jumper.

[0007] Preferably, the input jumper is a single-core jumper; the output jumper is a multi-core optical fiber; all the bare fibers of the output jumper are coated with a high-temperature resistant coating; and the multiple bare fibers of the output jumper are connected together at their ends by a fused taper method.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0028] Based on the problems existing in the prior art, this utility model provides a jumper fixing device with optical power attenuation and beam splitting functions.

[0030] Now see Figure 2 This utility model provides a jumper fixing device with optical power attenuation and beam splitting functions, including a base plate 1, a first Y-axis moving mechanism 2, a second Y-axis moving mechanism 3, a first Z-axis moving mechanism 4, a second Z-axis moving mechanism 5, a first fixing mechanism 6, and a second fixing mechanism 7. The first Y-axis moving mechanism 2 and the second Y-axis moving mechanism 3 are arranged sequentially on the base plate 1 along the same straight line; the first Z-axis moving mechanism 4 and the second Z-axis moving mechanism 5 are respectively connected to the first Y-axis moving mechanism 2 and the second Y-axis moving mechanism 3; the first fixing mechanism 6 and the second fixing mechanism 7 are respectively connected to the first Z-axis moving mechanism 4 and the second Z-axis moving mechanism 5; the first fixing mechanism 6 and the second fixing mechanism 7 are used to fix the input jumper 8 and the output jumper 9 respectively. By adjusting the first Y-axis moving mechanism 2, the second Y-axis moving mechanism 3, the first Z-axis moving mechanism 4, and the second Z-axis moving mechanism 5, the input jumper 8 and the output jumper 9 fixed to the first fixing mechanism 6 and the second fixing mechanism 7 are horizontally aligned to realize the transmission of optical signals; the output jumper 9 is a multi-core beam splitting jumper.

[0031] Specifically, when the input jumper 8 and output jumper 9 are horizontally aligned, the first fixing mechanism 6 and the second fixing mechanism 7 are very close together, resulting in limited operating space and making it inconvenient to disassemble or fix the input jumper 8 and output jumper 9. By adjusting the first Y-axis moving mechanism 2, the second Y-axis moving mechanism 3, the first Z-axis moving mechanism 4, and the second Z-axis moving mechanism 5, the first fixing mechanism 6 and the second fixing mechanism 7 are moved away from each other, and then the input jumper 8 and output jumper 9 are installed and fixed. After installation and fixing, the first Y-axis moving mechanism 2, the second Y-axis moving mechanism 3, the first Z-axis moving mechanism 4, and the second Z-axis moving mechanism 5 are adjusted again to make the input jumper 8 and output jumper 9 fixed to the first fixing mechanism 6 and the second fixing mechanism 7 horizontally aligned.

[0032] In some embodiments, the input jumper 8 is a single-core jumper; the output jumper 9 is a multi-core optical fiber; the multiple bare fibers of the output jumper 9 are coated with a high-temperature resistant coating; the multiple bare fibers of the output jumper 9 are connected together at their ends by a fused taper method.

[0033] Specifically, the input patch cord 8 is a single-mode fiber, and it can be seen from the input end face 81 and the output end face 82 of the input patch cord that the number of fiber cores is 1.

[0034] Specifically, the core spacing of the multiple bare fibers in the output jumper 9 is 125μm±5μm.

[0035] Specifically, the multiple bare fibers of output jumper 9 adopt a low crosstalk design (crosstalk ≤ -30dB) to ensure the independence of signals in each channel after splitting.

[0036] Specifically, the high-temperature resistant coating uses a polyimide coating, which can be used in environments up to 300°C.

[0037] In some embodiments, the number of bare fibers in the output jumper 9 is 2-8; preferably, the number of bare fibers is 4-8, which realizes multi-channel beam splitting and optical power attenuation, and can be connected to other devices such as optical power meters, spectrometers, and oscilloscopes respectively.

[0038] Specifically, from the input end face 91 and the output end face 92 of the output jumper, it can be seen that the number of fiber cores of the output jumper 9 can be 4, 5, 7, etc. The signal light is transmitted from the single fiber of the input jumper 8 to the multi-core fiber of the output jumper 9. A beam of light is coupled into the multi-channel fiber core, and the optical power is evenly distributed in each channel, reducing the optical power without affecting the optical signal quality.

[0039] In some embodiments, the output jumper 9 is equipped with a miniature attenuator, which is connected to the output jumper 9 via a threaded interface; the accuracy of the miniature attenuator is ±0.1dB, and the miniature attenuator further extends the attenuation range.

[0040] In some embodiments, both the first fixing mechanism 6 and the second fixing mechanism 7 include a fixing clamp, which is provided with a spring clamping structure. The spring clamping structure is provided with an adjustment knob, which can be used to adjust the clamping force of the spring clamping structure to adapt to the clamping of fiber optic patch cords of different diameters (250μm-900μm).

[0041] Specifically, the fixing fixture is compatible with fixing various types of input jumpers such as SC, LC, and MPO.

[0042] In some embodiments, the first Y-axis moving mechanism 2 and the second Y-axis moving mechanism 3 have the same structure, both including a guide rail, a slider, a lead screw, and a lead screw nut. The guide rail is horizontally arranged on the base plate, and the slider is arranged on the guide rail and can slide freely along the guide rail. The slider is connected to the lead screw nut, and the lead screw is threadedly connected to the lead screw nut. Rotating the lead screw drives the slider to move through the lead screw nut. The first Z-axis moving mechanism 4 and the second Z-axis moving mechanism 5 are respectively connected to the sliders of the first Y-axis moving mechanism 2 and the second Y-axis moving mechanism 3, thereby realizing the horizontal movement of the first Z-axis moving mechanism 4 and the second Z-axis moving mechanism 5 in the Y-axis direction.

[0043] Similarly, the first Z-axis moving mechanism 4 and the second Z-axis moving mechanism 5 can adopt the same structure as the first Y-axis moving mechanism 2 and the second Y-axis moving mechanism 3 to realize the movement of the first fixed mechanism 6 and the second fixed mechanism 7 in the Z-axis direction.

[0044] Specifically, the horizontal movement range of the first Y-axis moving mechanism 2 and the second Y-axis moving mechanism 3 is 0mm-50mm; the vertical movement range of the first Y-axis moving mechanism 2 and the second Y-axis moving mechanism 3 is 0mm-20mm.

[0045] In some embodiments, the lead screw is connected to a rocker arm or a motor, and the lead screw is driven to rotate by the motor or the rocker arm.

[0046] In some embodiments, a synchronization linkage mechanism 10 is provided between the first Z-axis moving mechanism 4 and the second Z-axis moving mechanism 5. The synchronization linkage mechanism 10 synchronizes the first Z-axis moving mechanism 4 and the second Z-axis moving mechanism 5, so that the input jumper 8 and the output jumper 9 fixed to the first fixing mechanism 6 and the second fixing mechanism 7 are kept in relative alignment.

[0047] Specifically, the synchronous linkage mechanism 10 only needs to synchronize the first Z-axis moving mechanism 4 and the second Z-axis moving mechanism 5; its structure is not limited here.

[0048] In some embodiments, the end faces of the input jumper 8 and the output jumper 9 are polished with APC (Angle Physical Contact) bevels to form bevels with an angle of 8°; this makes the return loss of the input jumper 8 and the output jumper 9 ≤ -60dB and the mating loss ≤ 0.2dB.

[0049] In some embodiments, both the first fixing mechanism 6 and the second fixing mechanism 7 are provided with physical limiting structures at their jumper insertion interfaces to prevent mistaken insertion and ensure that the jumper insertion direction is unique.

[0050] Specifically, the physical limiting structure can be a key, a slot, or a positioning pin.

[0051] In summary, the jumper fixing device with optical power attenuation and beam splitting functions provided by this utility model embodiment fixes the input jumper 8 and the output jumper 9 respectively through the first fixing mechanism 6 and the second fixing mechanism 7. The positions of the first fixing mechanism 6 and the second fixing mechanism 7 are adjusted by the first Z-axis moving mechanism 4, the second Z-axis moving mechanism 5, the first Y-axis moving mechanism 2 and the second Y-axis moving mechanism structure 3, which facilitates the installation and position adjustment of the input jumper 8 and the output jumper 9, so that the input jumper 8 and the output jumper 9 maintain a high-precision horizontal alignment; reduce docking loss; the output jumper 9 adopts a multi-core beam splitting jumper to achieve beam splitting and optical power attenuation.

[0052] Furthermore, output jumper 9 is configured with a miniature attenuator, which further extends the attenuation range.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
