When in use, one end of the optical fiber can be connected to the signal transmitting end 100 of the optical fiber detection device, and the red light button 710 is clicked, and the optical fiber detection device outputs a stable red light source. If a red light source can be seen at the other end of the optical fiber, it means that the optical fiber is intact.

[0046] As an implementation mode, the terminal device includes at least one of a terminal monitoring and display device, a computer device, and a mobile communication device. The STATCOM module has a signal acquisition module for acquiring the on-off signal of each optical fiber, and the terminal device has an acquisition module for acquiring the on-off signal.

[0047] The following introduces several working scenarios of the fiber optic detection system.

[0048] Embodiment 1: First, the power module 800 of the optical fiber detection device, such as the high voltage source module 820 or the low voltage source module 810, is connected to the STATCOM module, the STATCOM module has a signal acquisition module for acquiring the on-off signal of each optical fiber, and the terminal device has an acquisition module for acquiring the on-off signal. Press the power button 730 of the optical fiber detection device, the STATCOM module is powered on, the STATCOM module establishes a connection with the acquisition module of the terminal device through the signal acquisition module, and the on-off status of the optical fiber can be displayed through the terminal device, so as to determine whether the optical fiber is connected reversely, that is, this solution realizes the detection of the reverse connection of the optical fiber by powering by the power module 800.

[0049] Example 2: Please refer to Figure 3 , Figure 31 is a third schematic diagram of a portable optical fiber detection device provided by an embodiment of the present invention, wherein one end of the optical fiber is connected to the signal transmitting end 100 of the optical fiber detection device, and one end of the optical fiber is connected to the signal receiving end 200 of the optical fiber detection device. The optical fiber detection device includes a signal processing module 610, and the signal processing module 610 is connected to the signal receiving end 200, the signal transmitting end 100 and the display module 400. The signal processing module 610 is used to obtain the optical signal strength values ​​of the signal receiving end 200 and the signal transmitting end 100. Specifically, when the signal transmitting end 100 A light source signal is emitted, and the light source signal is transmitted to the other end of the optical fiber through reflection of the optical fiber. Then, the attenuation of the optical fiber and whether the optical fiber is connected reversely can be determined according to the light reflection signal received by the signal receiving end 200. Then, the light signal intensity values ​​of the signal receiving end 200 and the signal transmitting end 100 can be known by observing the display module 400. For example, it can be known by observation that the light intensity of the light source signal emitted by the signal transmitting end 100 is 100dbm. If the light intensity value of the light reflection signal received by the signal receiving end 200 is 0, that is, the signal receiving end 200 does not receive the light reflection signal, it can be determined that the optical fiber is connected reversely.

[0050] If the light intensity value of the light reflection signal received by the signal receiving end 200 is 80dbm, there is signal attenuation in the optical fiber, and its optical fiber attenuation rate ΔE=20%. Then the signal processing module 610 calculates the optical fiber attenuation rate ΔE according to the intensity values ​​of the signal receiving end 200 and the signal transmitting end 100, and transmits the optical fiber attenuation rate ΔE to the display module 400, and the display module 400 displays the specific value of the optical fiber attenuation rate ΔE. In this solution, the signal processing module 610 of the optical fiber detection device processes the light intensity of the signal receiving end 200 and the signal transmitting end 100, and displays it through the display module 400, thereby realizing quick detection of optical fiber attenuation and reverse optical fiber connection, making the optical fiber detection device more convenient to operate and intelligent.

[0051] Embodiment 3: The optical fiber detection device includes a communication module 600, wherein the optical fiber detection device establishes a connection with a terminal device through the communication module 600, and the terminal device may be a portable computer. After the optical fiber detection device establishes a connection with the portable computer through a wireless network or a wired network through the communication module 600, the optical fiber attenuation rate ΔE and the on-off state of the optical fiber connection may be transmitted to the portable computer. Optionally, the terminal device may be a mobile communication device such as a mobile phone and a terminal monitoring display device. The cooperation between the optical fiber detection device and the terminal device of this solution is conducive to the rapid detection of optical fiber attenuation and reverse optical fiber connection, and improves the user's product experience.
