DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0033] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0034] This embodiment relates to a multi-core optical fiber detection device, which is used to detect the multi-core optical fiber. One end of the multi-core optical fiber is an optical fiber end, and the other end has multiple optical fiber branch ends, such as Figure 1-6 As shown, it includes: a base 100, a light source generator 200, an optical fiber connection platform 300, and a light spot observation plate 400.

[0035] The light source generator 200, the optical fiber connection platform 300, and the light spot observation plate 400 are all arranged on the machine base 100, ensuring that the detection equipment has good equipment integrity, making the use of the equipment more stable and convenient. Among them, the light source generator 200 is a device for generating a light source and inputting it into a multi-core optical fiber. A fiber input port 210 is arranged on the light source transmitter, and the fiber input port 210 can be connected to the optical fiber end of the multi-core optical fiber, so that the light source generated by the light source generator 200 can be input from the optical fiber branch end into the multi-core optical fiber through the optical fiber input port 210 to detect the branch of the multi-core optical fiber. The optical fiber connection station 300 is the part that connects the other end of the multi-core optical fiber. An optical fiber connection port 310 is provided at one end of the optical fiber connection station 300 for connecting the optical fiber end of the multi-core optical fiber, so that the multi-core optical fiber is connected to the optical fiber connection station 300. An optical fiber output port 320 is provided at the other end of the optical fiber connection station 300. The optical fiber output port 320 corresponds to and communicates with the optical fiber connection port 310, so that the light of the optical fiber end of the multi-core optical fiber connected to the optical fiber connection port 310 is output from the optical fiber output port 320. The light spot observation plate 400 is arranged in front of the optical fiber output port 320, so that the light emitted from the optical fiber end through the optical fiber output port 320 can be irradiated on the light spot observation plate 400, and the light will form a light spot on the light spot observation plate 400. The inspection personnel can judge the state of a single branch of the multi-core optical fiber through the light spot information (shape, uniformity, etc.) on the light spot observation plate 400 to achieve the inspection effect.

[0036] In this embodiment, the detection device of the multi-core optical fiber also includes: a power detection module 500. The power detection module 500 is a component for detecting the power of the optical fiber, which is movably installed on the machine base 100, and the power detection module 500 can be switched between the first position state and the second position state. Among them, when the power detection module 500 is in the first position state, the power detection module 500 is located between the optical fiber output port 320 and the light spot observation plate 400, and the power detection module 500 is directly opposite to the optical fiber output port 320, so that the light emitted by the optical fiber end through the optical fiber output port 320 can be well irradiated on the power detection module 500, so as to perform power detection on the light output of the multi-core optical fiber, and the detection device is in the power detection state; when the power detection module 500 is in the second position state, the power detection module 500 is far away from the front of the optical fiber output port 320, ensuring that the power detection module 500 will not block the light emitted by the optical fiber end through the optical fiber output port 320, so that the light can directly irradiate the light spot observation plate 400, which is convenient for the detection personnel to observe and detect, and the detection device is in the light spot observation detection state. The movable installation form of the power detection module 500 enables the detection device to detect the power and light spot of the multi-core optical fiber, thereby improving the accuracy and data dimension of the detection and improving the detection effect. At the same time, the detection device can switch between the power detection state and the light spot observation state, and the switching will not interfere with the detection effect, so the use effect is better.

[0037] As a preferred solution, the power detection module 500 is slidably mounted on the frame, between the optical fiber output port 320 and the light spot observation plate 400, and can be moved left and right in the direction parallel to the optical fiber output port 320, so that the power detection module 500 can switch between the first position state and the second position state, so as to realize the switching of the two detection modes of the detection device and achieve a good switching effect. The sliding installation of the power detection module 500 enables the power detection module 500 to always maintain a stable height, ensuring that when in the first position state, the power detection module 500 can receive the light of the multi-core optical fiber to achieve a good detection effect. In this embodiment, the power detection module 500 is slidably mounted on the frame by a sliding cylinder 600, which can not only automatically switch the position state of the power detection module 500 by the sliding cylinder 600, but also make the position state switching of the power detection module 500 more stable and reliable, thereby improving the overall automation and use stability of the detection device. Of course, in other embodiments, the power detection module 500 can also be movably installed on the rack through other structures and forms, so that the power detection module 500 can switch between the first position state and the second position state, or the power detection module 500 can also be detachably installed on the rack, and a mounting position for the power detection module 500 to be installed so that it is in the first position state, or the first position state and the second position state is provided on the rack to achieve the switching effect of the power detection module 500.

[0038] In this embodiment, the detection device also includes: a display device 700. The display device 700 is electrically connected to the power detection module 500 to display the detection result of the power detection module 500 on the display device 700, so that the detection personnel can directly complete the detection of the multi-core optical fiber through the display device 700. As a preferred solution, the light source generator 200 is electrically connected to the display device 700 to display the light power emitted by the power generator on the display device 700. The light power emitted by the power generator and the detection result of the power detection module 500 can be displayed on the display device 700 at the same time, and the two data can be compared and analyzed, which is more intuitive and clear.

[0039] In this embodiment, a plurality of optical fiber input ports 210 are provided on the light source generator 200 to respectively connect to a plurality of optical fiber branch ends of a multi-core optical fiber, so as to conveniently and quickly detect a plurality of optical fiber branches of the multi-core optical fiber and improve detection efficiency.

[0040] As a preferred solution, a heat sink 800 is also provided on the light source generator 200 to dissipate heat and cool the light source generator 200, so as to prevent the light source generator 200 from working at too high a temperature for a long time, thereby affecting the working temperature and use safety of the test equipment. Specifically in this embodiment, the heat sink 800 includes: a heat conduction block 810 connected to the light source generator 200, a heat dissipation fin 820 provided above the heat conduction block 810, and a heat dissipation fan 830 provided above the heat dissipation fin 820 to increase the air flow in the heat dissipation fin 820. In order to achieve a good heat dissipation effect.
