Description

Optical fiber detecting method and device

The present invention relates to a fiber detecting method and device, and in particular to an optical fiber detecting method and device capable of streamlining the detecting personnel and improving the correctness of the detecting.

Optical fiber has low loss, high fax, high frequency and low interference, so it is widely used in telecommunications or networking. In the process of fiber erection and maintenance, fiber optic detection devices must be used to measure connectivity between the equipment room and the customer premises.

3 is a schematic plan view of a conventional optical fiber detecting device. As shown in FIG. 3, the conventional optical fiber detecting device 30 includes an optical cable (OCI) 31, a splitter 32, and a reflector 33. During fiber erection, a machine room 34 and a beam splitter 32 are connected through a first fiber optic cable 35, and the beam splitter 32 and a plurality of end users 37 are connected through a plurality of second fiber optic cables 36.

When detecting the fiber optic cable, for example, to determine which of the second fiber optic cables 36 to which the user to be tested 37A is connected, the first inspector 38 sets the fiber optic detector 31 to the machine room 34, and the second detection The person 39 sets the light reflector 33 to the user 37A to be tested. The third inspector 40 taps (k) at the position of the beam splitter 32 to locate the splitter 32 and a selected second fiber optic cable 36. The fiber optic oscillation signal is transmitted from the tapping point to the photo reflector 33, and the light is reflected. The device 33 reflects the fiber oscillation signal to the equipment room 34. If the fiber detector 31 at one end of the equipment room 34 detects the fiber oscillation signal, it can be determined that the second fiber cable 36 that is tapped is indeed connected to the beam splitter 32 and is to be tested. A second fiber optic cable 36 between the users 37A. On the other hand, if the third detecting person 40 taps a second optical fiber cable 36 at the position of the optical splitter 32, but the optical fiber detector 31 does not detect the optical fiber oscillation signal, it indicates that the second optical fiber cable 36 is not connected. The second optical fiber cable 36 between the user end 37A to be tested or the user 37A to be tested and the optical splitter 32 is disconnected and needs to be repaired.

However, in the conventional optical fiber detecting device 30, if the sensitivity of the optical fiber detector 31 is insufficient and the optical fiber cable is excessively worn, the optical fiber detector 31 may not accurately detect the tapping state. In addition, if the sensitivity of the optical fiber detector 31 located in the equipment room 34 is too high and the cable quality is good, a small oscillation will be detected, resulting in failure to recognize the correct tapping state. On the other hand, each test needs to dispatch three inspectors 38, 39, 40 located in the machine room 34, the optical splitter 32, and the location of the user 37A to be tested, in order to perform fiber inspection, which is time-consuming and labor-intensive.

Therefore, there is a need to design a fiber detecting device that can reduce the number of inspectors and accurately detect the oscillation signal without inaccurate detection due to the state of the fiber optic cable or the fiber optic detector.

The purpose of the present invention is to provide an optical fiber detecting device through which the detecting personnel can be reduced and the optical fiber cable can be correctly detected without being affected by the state of the optical fiber cable or the optical fiber detector.

According to the above object, the present invention provides a fiber detecting device, comprising: a light reflector disposed between a machine room and a beam splitter; a light splitter disposed between the machine room and the plurality of end users, through a first A fiber optic cable is connected to the optical splitter and the equipment room, and the optical splitter is connected to the end users through a plurality of second optical fiber cables; and a fiber optic detector is disposed on one of the end users.

Another object of the present invention is to provide an optical fiber detecting method by which the number of detecting personnel can be reduced without affecting the optical fiber detecting effect.

According to the above objective, the present invention provides a fiber detecting method, comprising: disposing a light reflector between a machine room and a beam splitter, wherein the machine room is connected to the beam splitter through a first fiber optic cable; Intersecting one of the plurality of second optical fiber cables to generate an oscillation signal; determining whether the second optical fiber cable is tapped according to whether the optical fiber detector detects whether the oscillation signal is detected Whether it is connected between the splitter and the user to be tested.

Through the above-mentioned optical fiber detecting method and device, it is only necessary to set two detecting personnel at the position of the optical splitter and the user to be tested, so that it can correctly determine which second optical fiber cable is connected to the user to be tested.

The technical means adopted by the present invention for achieving the intended purpose of the invention are further explained below in conjunction with the drawings and the preferred embodiments of the present invention.

FIG. 1A is a schematic diagram of the optical fiber detecting device of the present invention. As shown in FIG. 1A, the optical fiber detecting device 10 includes an optical fiber detector 11, a beam splitter 12, and a light reflector 13. The splitter 12 used in the present invention is a two-input and multiple-out splitter 12 having a first input port 121, a second input port 122, and a plurality of output ports 123. These input ports and output ports are bidirectionally transmittable. The connection of the signal 埠. The first fiber optic cable 14 is connected to the first input port 121 of the machine room 15 and the beam splitter 12, and the output ports 123 of the beam splitter 12 are connected to the plurality of end users 17 through a plurality of second fiber optic cables 16.

When detecting the optical fiber, the first detecting person 18 sets the optical reflector 13 to the front end of the first input port 121 of the optical splitter 12, and the second detecting person 19 sets the optical fiber detector 11 to a position of the user 17A to be tested. When the first inspector 18 taps (k) a second fiber optic cable 16 at the location of the beam splitter 12, a fiber optic oscillation signal having a particular wavelength is produced. If the second detecting person 19 at the position of the user 17A to be tested detects the fiber oscillation signal through the fiber detector 11, it means that the tapped second fiber cable 16 is indeed connected between the user 17A to be tested and the beam splitter 12. . If the second detecting person 19 does not detect the fiber oscillation signal through the fiber detector 11 at the position of the user 17A to be tested, it indicates that the second fiber cable 16 is not connected to the user 17A and the beam splitter 12, the first detection The person 18 must choose to tap another second fiber optic cable 16 until a second fiber optic cable 16 connecting the user 17A to be tested and the beam splitter 12 is found.

When the light reflector 13 is disposed at the first input port 121 of the beam splitter 12, the network usage of the plurality of end users 17 is affected. Therefore, when the light reflector 13 is to be disposed on the first input port 121 of the beam splitter 12, it is necessary to inform in advance that a plurality of terminal users 17 will suspend the network service for the setting operation. Such an arrangement sometimes causes inconvenience to the end user 17, so the timing at which the photo reflector 13 is disposed at the first input port 121 of the optical splitter 12 is usually when the optical network is initially set up, at which time a plurality of end users 17 The network service is not activated, and the light reflector 13 can be disposed on the first input port 121 of the beam splitter 12 to start the detecting operation.

FIG. 1B is a schematic plan view of an optical fiber detecting apparatus according to another embodiment of the present invention. As shown in FIG. 1B, in various embodiments, the first detector 18 can place the light reflector 13 on the second input port 122 of the beam splitter 12. The tester of any manufacturer can set the detecting instrument to the second input port 122 when the test is needed. Specifically, the second input port 122 can be connected to the fiber patch cord 20 first, and the detecting instrument or the light reflector 13 is connected to the fiber. The test end 201 of the patch cord 20, or the second input port 122, is first connected to the photo reflector 13, and the photo reflector 13 is connected to the fiber patch cord 20, which is not limited herein. When a plurality of end users 17 have started to use the network service, the first inspector 18 can set the created photo reflector 13 on the second input port 122 of the splitter 12 without affecting the network usage of the end user 17. When the test ends, the first inspector 18 removes the photo reflector 13 from the second input port 122 of the beam splitter 12, so that the testers of other manufacturers can perform different tests on the test end 201.

FIG. 2 is a flow chart of the optical fiber detecting method of the present invention. As shown in FIG. 2, the optical fiber detection method of the present invention includes the following steps. In step S201, a light reflector is disposed between a machine room and a beam splitter, and the machine room is connected to the beam splitter through a first optical fiber cable, and the light reflector is disposed at a position of the light splitter through the first detecting personnel. The light reflector can be disposed between the machine room and the beam splitter, and the light reflector can be disposed on the first input port or the second input port of the beam splitter, but is not limited herein.

In step S202, a fiber detector is set to be a user to be tested, and the second detecting person selects one of the plurality of terminal users to set the fiber detector to the end user, and the terminal user is to be tested. The user, the first inspector and the second inspector need to detect which second fiber optic cable is connected to the user to be tested.

In step S203, a second fiber optic cable is tapped to generate an oscillating signal, and when the first detecting person strikes the second fiber optic cable, an oscillating signal having a specific wavelength is generated. The oscillating signal is transmitted from the second fiber optic cable to the first fiber optic cable. The photo reflector on the first fiber optic cable reflects the oscillating signal to enhance the intensity of the oscillating signal, and then transmitted to the user at the test. Fiber detector. In general, the intensity of the oscillating signal is not sufficient for the fiber detector to detect the oscillating signal, and the optical detector can enhance the intensity of the oscillating signal to enable the fiber detector to detect.

In step S204, when the optical fiber detector detects the oscillation signal, it is confirmed that the user to be tested is connected to the optical splitter through one of the second optical fiber cables that the second detecting person strikes. When the optical fiber detector detects the oscillation signal with the specific wavelength, it indicates that the second optical fiber cable that the first detecting person hits is the optical fiber cable connected to the user to be tested. If the fiber optic detector does not detect an oscillating signal according to the particular wavelength, the first inspector further taps the other second fiber optic cable until a second fiber optic cable is connected to the test user.

Through the above-mentioned optical fiber detecting method and device, only two inspectors are required, and three inspectors are required compared with the existing optical fiber detecting method and device, which can reduce the number of inspectors. On the other hand, the first inspector places the photo reflector at a position adjacent to the optical splitter, and the distance between the present optical reflector and the optical fiber detector is closer than the distance between the existing optical reflector and the optical fiber detector. The detection effect is good, and it can correctly judge which second optical fiber cable is connected to the user to be tested.
