[0002] The integrated red light source and optical power unit is mainly used for line testing, fault diagnosis and signal verification in the construction and maintenance of optical fiber communication. It integrates two major functions: red light visual positioning and optical power measurement.
[0003] When testing fiber optic cables from the rooftop to the floor, especially when there are multiple fibers within the fiber optic conduit, two such integrated testing machines are required. On the rooftop, one end of the fiber under test is connected to the red light interface of integrated machine A. On the floortop, after locating the corresponding fiber using the red light, the other end of the fiber under test is connected to the light source interface of integrated machine B. Then, the red light interface of integrated machine A is turned off, and the other end of the fiber under test is manually connected to the optical power interface of integrated machine A. The link loss of the fiber under test can be determined by the obtained optical power.

Detailed Implementation
[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0019] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following examples illustrate this. Figures 1 to 6 This application provides a detailed description of the remotely controllable fiber optic testing system, equipment, method, and storage medium provided in its embodiments.
[0021] Please refer to Figure 1 This is a structural block diagram of a remotely controllable optical fiber testing system provided in an embodiment of this application. The optical fiber testing system 10 includes a first optical fiber testing device 101 and a second optical fiber testing device 102. The output port of the first optical fiber testing device 101 and the output port of the second optical fiber testing device 102 are connected to the optical fiber under test. The first optical fiber testing device 101 includes a first control module 1011 and a first laser module 1012 and a first optical power module 1013 connected to the first control module 1011. The second optical fiber testing device 102 includes a second control module 1021 and a second laser module 1022 and a second optical power module 1023 connected to the second control module 1021. The emission wavelength of the first laser module 1012 is different from that of the second laser module 1022. For example, the emission wavelength of the first laser module 1012 can be 650nm, and the emission wavelength of the second laser module 1022 can be 1550nm.
[0022] In actual use, such as Figure 2As shown, the first optical fiber testing device 101 acts as the host, emitting a 650nm laser, and PD1 corresponds to the first optical power module 1013. The second optical fiber testing device 102 acts as the slave, emitting a 1550nm laser, and PD2 corresponds to the second optical power module 1023. First, the output port of the host is connected to the optical fiber under test on the rooftop, and the first laser module 1012 is manually turned on. Then, the corresponding optical fiber is found on the ground floor and connected to the output port of the slave unit. The optical power is obtained and displayed through optical fiber message communication. That is, when the second optical power module 1023 detects the emitted light of the first laser module 1012, the second control module 1021 sends a first message to the first control module 1011 to turn off the first laser module 1012 and receives a second message from the first control module 1011 to turn on the second laser module 1022. When the first optical power module 1013 detects the emitted light of the second laser module 1022, the first control module 1011 receives a third message from the first control module 1011. The third message includes the first optical power of the first optical power module 1013, which can be the average value of multiple measurements. The emitted optical power of the second laser module 1022 is fixed, which facilitates the rapid determination of link loss. This achieves visual positioning and optical power measurement without the need to switch interfaces or frequently go up and down stairs, thus improving processing efficiency.
[0023] In some embodiments of this application, in sending the first message to the first control module 1011, the second control module 1021 is specifically used to turn the second laser module 1022 on or off within a preset period, so that the first control module 1011 obtains the first message based on the second optical power of the first optical power module 1013 within the preset period (as shown in Table 1). For example, the preset period can be 40ms, that is, it turns on or off every 5ms. Then, the data 01000001 formed 8 times is converted to ASCII code A, the data 01010100 is converted to ASCII code T, etc., where the presence of light is 1 and the absence of light is 0. Of course, it can also be compared with a preset threshold, which can avoid stray light interference and obtain more accurate results. For example, the 1550nm laser power received by the first optical power module 1013 is represented as 1 if it is greater than -2dBm, and as 0 if it is less than or equal to -2dBm, while the 650nm laser power received by the second optical power module 1023 is represented as 1 if it is greater than 5mW, and as 0 otherwise.

[0025] Then, the host can reply with a message indicating that the first laser module has been turned off, as shown in Table 2.
[0026] Table 2. Host's reply message indicating that the first laser module has been shut down.
[0027] Furthermore, regarding receiving the second message sent by the first control module 1011, when the first control module 1011 turns the first laser module 1012 on or off within a preset period, the second control module 1021 is specifically used to obtain the second message based on the first optical power of the second optical power module 1023 within the preset period, as shown in Table 3.
[0028] Table 3. Messages sent by the host to activate the second laser module
[0029] Then, the secondary unit can reply with a message indicating that the second laser module has been activated, as shown in Table 4.
[0030] Table 4. Sub-machine's reply message indicating that the second laser module is enabled.
[0031] Furthermore, regarding receiving the third message sent by the first control module 1011, when the first control module 1011 turns the first laser module 1012 on or off within a preset period, the second control module 1021 is specifically used to obtain the third message based on the second optical power of the second optical power module 1023 within the preset period, as shown in Table 5. That is, the 1550nm laser power received by the first optical power module 1013 is -4.99dBm. By comparing this value with the fixed output optical power of the second laser module 1022, the link loss can be determined. Of course, the second control module 1021 can also have a built-in algorithm to automatically calculate and display the link loss based on the first optical power of the first optical power module 1013, which is convenient and fast.
