The following explains key terms appearing in the present invention.
Example 1:

Referring to fig. 1-4, the remote triggered optical fiber alignment apparatus includes a remote triggered optical fiber alignment instrument 100 and a handheld terminal 200.

The first master control unit 102 is in signal connection with the first wireless communication unit 103. The first main control unit 102 is connected to the laser driving unit 104, the laser driving unit 104 is connected to the laser 101, and the first main control unit 102 controls the laser 101 to be turned on or turned off through the laser driving unit 104. The signal output of the laser 101 is connected to a set of optical fiber connectors 106 through an optical switch 105. The optical fiber connectors 106 are used for accessing optical fibers to be tested, and each optical fiber connector 106 can be jumped to connect an optical fiber. Each optical fiber connector 106 is provided with a connector number for distinguishing other optical fiber connectors one by one, each connector number is an integer selected from 1, 2, 3, and N, and the size of N is equal to the total number of the optical fiber connectors 106.

And the second input unit 201 and the second wireless communication unit 203 are respectively in signal connection with the second main control unit 202. The second wireless communication unit 203 is used in cooperation with the first wireless communication unit 103 for realizing communication between the remote triggered fiber-to-fiber instrument 100 and the handheld terminal 200. The second input unit 201 is used in cooperation with each of the optical fiber connectors 106, and is used for inputting an optical path selection command. The optical path selection command may be a connector number of the optical fiber connector 106. Different optical path selection commands correspond to different output optical paths on the optical switch 105.
The step of testing the tested cable based on the remote triggering type optical fiber alignment equipment comprises the following steps:
first, as shown in fig. 4, the optical fiber connector 106 of the remote triggering type optical fiber alignment instrument 100 is first jumped to one end (hereinafter referred to as "a end") of the tested cable, and the remote triggering type optical fiber alignment instrument 100 is turned on (i.e., powered on).

Therefore, based on the invention, a tester can simultaneously connect a plurality of cables to be tested of the tested cable to the remote triggering type optical fiber alignment instrument 100, thereby saving the round-trip wiring time of the tester to a certain extent and further improving the testing efficiency to a certain extent.
The initial state of each output optical path of the optical switch 105 is an off state.
Step two, at the B end of the tested optical cable, sending an optical path selection instruction to the remote triggering type optical fiber alignment instrument 100 through the handheld terminal 200, specifically comprising the steps of:
(a) starting the handheld terminal 200;
(b) at the B end of the measured cable, a connector number of the optical fiber connector 106 to which the cable to be measured having the target fiber sequence at the a end of the measured cable is connected is input through the second input unit 201 of the handheld terminal 200, for example, a connector number M to which the cable to be measured L having the fiber sequence M at the a end of the measured cable is connected is input (a fiber sequence pair detection process corresponding to any other cable to be measured except for the cable having the fiber sequence M at the a end of the measured cable is input, corresponds to a fiber sequence pair detection process corresponding to the cable to be measured L having the fiber sequence M at the a end of the measured cable); the optical fiber connector 106 corresponding to the connector number M is connected with the cable to be tested L with the fiber sequence M at the end A of the cable to be tested through fiber jumping; the target fiber sequence is the fiber sequence of the cable to be tested at the end A of the cable to be tested, which is currently subjected to fiber sequence pair testing, at the end A of the cable to be tested;
(c) the second main control unit 202 of the handheld terminal 200 generates an mth optical path selection instruction corresponding to the connector number M based on the connector number input in the second input unit 201, for example, based on the connector number M, and calls the second wireless communication unit 203 to send the mth optical path selection instruction to the remote trigger type optical fiber alignment instrument 100.
The M-th optical path selection instruction is used for remotely controlling the remote triggered optical fiber alignment instrument 100 to realize optical path switching to the optical switch 105, and is used for remotely controlling the remote triggered optical fiber alignment instrument 100 to switch the optical path of the optical switch 105 to a path communicated with the corresponding optical fiber connector 106.
Step three, the remote triggered optical fiber alignment instrument 100 receives the optical path selection instruction sent by the handheld terminal 200, for example, the remote triggered optical fiber alignment instrument 100 receives the mth optical path selection instruction sent by the handheld terminal 200, and then controls the optical path switching of the optical switch 105 based on the received mth optical path selection instruction, so as to send an optical signal to the cable L to be tested whose fiber sequence at the a end of the cable to be tested is M, which specifically includes:
(a) the first main control unit 102 of the remote triggered fiber-to-fiber instrument 100 receives the mth optical path selection instruction sent by the second wireless communication unit 203 of the handheld terminal 200 through the first wireless communication unit 103;
(b) the first main control unit 102 generates a target optical path selection control signal for controlling the conduction of an optical path (hereinafter referred to as a "target optical path") in which the optical fiber connector 106 corresponding to the connector number M is located based on the received mth optical path selection instruction, and sends the target optical path selection control signal to the optical switch 105;
(c) the optical switch 105 receives and selects the control signal according to the target optical path, and selects and switches the optical path to the target optical path. So far, the optical signal emitted by the laser 101 can be output to the cable L to be tested, which has a fiber sequence of M, at the end of the cable a to be tested through the target optical path of the optical switch 105 and the optical fiber connector 106 corresponding to the connector number M.
Step four, detecting the light receiving condition of the corresponding optical fiber at the B end of the detected optical cable (namely, the B end of the detected optical cable has the core wire of the target optical fiber sequence) in real time through real-time line-of-sight observation or by using an optical power meter, and judging whether the optical fiber sequence of the detected optical cable is accurate, wherein the specific judgment method comprises the following steps:
(a) when a sight line observes that the corresponding optical fiber of the B end of the tested cable has light, or an optical power meter detects that the corresponding optical fiber of the B end of the tested cable has an optical signal, determining that a cable to be tested, of which the A end of the tested cable has the target fiber sequence, is consistent with a core wire, of which the B end of the tested cable has the same target fiber sequence, and that the fiber sequence of the cable to be tested, of which the A end of the tested cable has the target fiber sequence, is correct;
(b) when the optical power meter detects that the optical fiber of the detected cable B end has other fiber sequences is light or an optical signal, the fiber sequence error of the cable to be detected at the detected cable B end, which has the target fiber sequence at the detected cable A end, can be judged;
(c) when no optical signal or optical signal is observed or detected by any core optical fiber at the B end of the tested optical cable, the interruption of the fiber sequence of the current tested optical fiber can be judged.
