[0030] See Figure 1 The fiber optic power testing device in this embodiment includes a testing cabinet 1, a heat release cabinet 2, a water chiller 3, a control host 4, an air purification component 5, and an indicator light component 6.

[0031] The heat release cabinet 2 is located on the left side of the test cabinet 1, the water chiller 3 and the control host 4 are located on the right side of the test cabinet 1, the air purification component 5 is located above the test cabinet 1, and the indicator light component 6 is located above the test cabinet 1.

[0032] The test cabinet 1 includes an upper cabinet 11 and a lower cabinet 12, with the upper cabinet 11 positioned above the lower cabinet 12.

[0033] The upper cabinet 11 includes a test bench 111, a left side baffle 112, a rear side baffle 113, a right side baffle 114, a front safety door assembly 115, a three-axis moving platform 116, a first camera 117, and a thermal imager 118.

[0034] The left side baffle 112, rear side baffle 113, right side baffle 114, and front safety door assembly 115 are sequentially fixedly installed on the test platform 111 along its circumference, forming a closed space together with the top plate of the upper cabinet 11. A three-axis moving platform 116 is fixed on the test platform 111. Two first cameras 117 are respectively installed inside the left side baffle 112, and two other first cameras 117 are respectively installed inside the right side baffle 114.

[0035] The three-axis moving platform 116 includes a first slide rail assembly 71, a second slide rail assembly 72, and a third slide rail assembly 73. The first slide rail assembly is fixed to the test platform 111 and is adjacent to the left side baffle 112. The second slide rail assembly 72 is fixed to the test platform 111 and is adjacent to the right side baffle 114. The third slide rail assembly 73 is disposed on the first slide rail assembly 71 and the second slide rail assembly 72.

[0036] The first slide rail assembly 71 includes a first support column 711 and a first track 712. The first support column is fixed on the test platform, and the first track 712 is fixed on the first support column 711. The first track 712 is slidably connected to the first slider 731.

[0037] The second slide rail assembly 72 includes a second support column 721 and a second track 722. The second support column 722 is fixed on the test platform 111, and the second track 722 is fixed on the second support column 721. The second track 722 is slidably connected to the second slider 732.

[0038] The third slide rail assembly 73 includes a first slider 731, a second slider 732, a third slider 733, a third track 734, and a vertical movement mechanism 735. The first slider 731 is slidably connected to the first slide rail assembly 71 via the first track 715.

The vertical movement mechanism 735 is fixed to the third slider 733 and is connected to a thermal imager 118. The thermal imager 118 is used to detect the temperature of the test platform 111.

[0039] Thus, by sliding the first slider 731 on the first track 712 and the second slider 732 on the second track 722, the thermal imager 118 achieves movement in the X-axis direction; by interacting with the third slider 731 on the third track, the thermal imager achieves movement in the Y-axis direction; and by the action of the vertical moving mechanism, the thermal imager achieves movement in the Z-axis direction. The X-axis, Y-axis, and Z-axis are perpendicular to each other. The X-axis direction is the length direction of the first track 712, the Y-axis direction is the length direction of the second track 722, and the Z-axis direction is the length direction of the third track 734. Thus, the thermal imager can achieve three-axis movement to detect the optical fiber on the test platform.

[0040] The front safety door assembly 115 includes a shielding door 81, a door safety switch 82, a connecting plate 83, a first door slide rail 84, and a second door slide rail 85. The shielding door 81 is provided with a connection terminal 811 that mates with the door safety switch 82 and an observation window 812 for observing the situation inside the upper cabinet 11. The shielding door 81 is movably connected to the door safety switch 82 via the connection terminal 811.

[0041] The connecting plate 83 connects the test platform 111, the left baffle 112, and the right baffle 113. The first door slide rail 84 is mounted on the left baffle 113 and is perpendicular to the connecting plate 83. The second door slide rail is mounted on the right baffle 113 and is perpendicular to the connecting plate 83. The door safety switch 82 is mounted on the connecting plate 83, and the shielding door 81 is movably connected to the door safety switch 82 via the first door slide rail 84 and the second door slide rail 85.

[0042] The lower cabinet 12 includes a laser 121. The test platform 111 is provided with a first connecting through hole 901, which connects the upper cabinet 11 and the lower cabinet 12. The door safety switch 82 is interlocked with the enable terminal of the laser 121, so that the laser 121 can only start to output laser light when the connecting terminal 811 is inserted into the door safety switch 82.

[0043] The heat release cabinet 2 is specifically located on the outside of the left side baffle 112. The left side baffle has a first opening 1120, and the heat release cabinet has a second opening (not shown in the figure). The first opening 1120 has the same shape and size, and the first opening 1120 is connected to the second opening.

[0044] The heat release cabinet 2 includes a water tank 21, a second opening, a support frame 23, a second camera 24, and a second connecting through hole 902. The water tank 21 is located below the second opening, and the second connecting through hole 902 is located above the second opening, serving to connect the heat release cabinet 2 to the external environment. The support frame 23 is located between the second opening and the second connecting through hole 902.

[0045] When performing fiber optic power testing using the fiber optic power testing device of this embodiment, the operator prepares the fiber optic cable to be tested, including a Bragg grating, and places it on the test platform 111. The first end of the fiber optic cable with the Bragg grating is passed through the first connecting through-hole 901 and connected to the laser 121. The last end of the fiber optic cable is led out from the second connecting through-hole through the first opening and the second opening. Then, the operator connects the connecting terminal 811 of the shielding door 81 to the door open / close switch 82, thereby forming a closed test space. The operator operates the control host 4 in the test space, thereby controlling the host 4 to start and perform power testing on the fiber optic cable. During this period, the operator records the image on the first camera 117 or directly observes the situation of the upper cabinet 11 through the observation window 812, and observes the situation inside the heat release cabinet 2 through the second camera 24.

[0046] After the control host 4 is started, it controls the output power of the laser 121 and simultaneously controls the three-axis moving platform 116 to move the thermal imager 118 to the position of the fiber optic cable under test, recording the temperature of the test point at different power levels, thereby automating the power test. In case of abnormalities, such as when the temperature exceeds a preset threshold, the operator is alerted via an indicator light assembly or the corresponding display screen 41 on the control host.

[0047] During automated power testing, the water chiller 3 dissipates heat from the test platform. Inside the heat release cabinet, the end of the optical fiber under test passes over the water tank 21, which dissipates heat from that portion of the fiber.

[0048] In summary, this invention improves the efficiency of fiber optic power testing, optimizes the layout of the test cabinet, and saves space; it allows the fiber under test to be laid directly on the test table for convenient testing; it enables automatic testing by one person, saving manpower; and it makes the testing process safer by interlocking the door safety switch with the laser enable terminal.
