Description

Technical Field

[0001] The present invention relates to the field of optical fiber technology, and in particular to an optical fiber coupler and a monitoring system, and an occupancy status monitoring method. Background Art

[0002] With the development of communication technology, telecom operators are deploying fiber optic networks more and more widely. Fiber optics are deployed in segments. Fiber couplers are usually used to connect these segmented fibers into service optical paths. Fiber optic networks have the advantages of low cost and large bandwidth, but since the entire network, except for the communication equipment at the initial end (A end) and the terminal end (Z end), is in a "passive" state, it is called "dumb resources" in the industry.

[0003] At present, network maintenance personnel usually perform fiber jumpering according to the optical path service work order, and use fiber couplers and fiber jumpers to connect these segmented optical fibers into a complete service optical path. When it is necessary to monitor the occupancy status of each fiber coupler, due to its "dumb resource" characteristics, it can only be monitored through the service work order data. However, when network maintenance personnel complete the service optical path according to the optical path service work order, due to individual differences among network maintenance personnel, a large number of fiber jumper operations are not performed in accordance with the requirements on the service work order, which leads to a huge gap between the actual occupancy of the fiber coupler and the service work order data. According to industry experience data, the consistency rate between the service work order data and the on-site occupancy is only 60%, and the network management department does not have sufficient human resources to discover this gap in time. This gap makes it impossible for operators to grasp the use of network resources, and it is impossible to make full use of existing network resources, resulting in a large amount of network resource waste; at the same time, the inconsistency between the service work order data and the actual situation on site also leads to low efficiency in network troubleshooting, low speed in opening new services, and low user satisfaction.

[0004] Therefore, when the business work order data is used to monitor the occupancy of each optical fiber coupler, the actual occupancy status of some optical fiber couplers cannot be reflected. Therefore, the accuracy of monitoring the occupancy status of the optical fiber coupler in the existing method is low. Summary of the invention

[0104] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0105] like Figure 1 As shown, an embodiment of the present invention provides a fiber optic coupler, the fiber optic coupler comprising:

[0106] A coupler body 101 and at least one occupancy monitoring element 102; the at least one occupancy monitoring element 102 is arranged in the coupler body 101;

[0107] Each of the occupancy monitoring elements 102 is used to monitor whether the coupler body 101 is in an occupied state, and if so, to send occupancy state information to an external monitoring device.

[0108] according to Figure 1 In the embodiment shown, the fiber optic coupler includes a coupler body and one or more occupancy monitoring elements disposed in the coupler body. Each occupancy monitoring element can monitor whether the coupler body is in an occupied state. When it is detected that the coupler body is in an occupied state, occupancy status information is sent to an external monitoring device so that the monitoring device can promptly understand the occupancy status of the fiber optic coupler based on the occupancy status information. It can be seen from the above that in the embodiment of the present invention, since the occupancy monitoring element is located in the coupler body, the actual occupancy status of the coupler body can be accurately monitored. Therefore, the solution provided in the embodiment of the present invention can improve the accuracy of monitoring the occupancy status of the fiber optic coupler.

[0109] In one embodiment of the present invention, Figure 1 The fiber optic coupler shown is only an example. The type of coupler body and the type of occupancy monitoring element can be determined according to business requirements. Figure 1The coupler body shown in FIG. 1 is an FC type coupler body and includes two occupancy monitoring elements.

[0110] In one embodiment of the present invention, the above Figure 1 The specific type of the coupler body 101 shown in the figure can be determined according to business requirements. Generally, the coupler body can include but is not limited to any one of an FC type coupler body, an SC type coupler body, an ST type coupler body and an LC type coupler body.

[0111] In this embodiment, if there are specific business requirements, the coupler body can also be any one of an MTRJ-type adapter body, an MPO-type adapter body, and an E2000-type adapter body.

[0112] According to the above embodiment, since the coupler body can be selected as any one of the FC type coupler body, the SC type coupler body, the ST type coupler body and the LC type coupler body according to business requirements, the business applicability is relatively strong.

[0113] In one embodiment of the present invention, the at least one occupancy monitoring element 102 may include a jumper fiber occupancy monitoring element 1021 and / or a service occupancy monitoring element 1022 .

[0114] In this embodiment, the type of occupancy monitoring element can be selected according to specific service requirements. For example, when only the occupancy status of the jumper fiber of the coupler body needs to be monitored, the jumper fiber occupancy monitoring element can be selected; when only the service occupancy status of the coupler body needs to be monitored, the service occupancy monitoring element can be selected; when both the jumper fiber occupancy status of the coupler body and the service occupancy status need to be monitored, both the jumper fiber occupancy monitoring element and the service jumper fiber occupancy monitoring element can be selected.

[0115] In this embodiment, when a patch cord plug is inserted into the coupler body, no matter whether the patch cord plug carries any service, the patch cord occupancy monitoring element can detect that the coupler body is in an occupied state.

[0116] In this embodiment, only when a patch cord plug is inserted into the coupler body and the patch cord plug carries a service, the service occupancy monitoring element can detect that the coupler body is in an occupied state.

[0117] According to the above embodiment, since the occupancy monitoring element can include one or both of the jumper fiber occupancy monitoring element and the service occupancy monitoring element according to service requirements, the service applicability is relatively strong.

[0118] In one embodiment of the present invention, the configuration of the occupancy monitoring element in the optical fiber coupler may include at least the following situations:

[0119] Case 1:

[0120] In one embodiment of the present invention, when the at least one occupancy monitoring element 102 includes a jumper occupancy monitoring element 1021,

[0121] The fiber jumper occupancy monitoring element 1021 is used to monitor whether the coupler body 101 is in a fiber jumper occupancy state, and if so, send fiber jumper occupancy state information to the monitoring device.

[0122] In this embodiment, the patch cord occupancy monitoring element is used to monitor whether a patch cord plug is inserted into the coupler body. If it is detected that a patch cord plug is inserted into the coupler body, it can be detected that the coupler body is in a patch cord occupied state, and the patch cord occupied state information is sent to the monitoring device to inform the monitoring device that the coupler body is in a patch cord occupied state.

[0123] Case 2:

[0124] In one embodiment of the present invention, when the at least one occupancy monitoring element 102 includes a service occupancy monitoring element 1022,

[0125] The service occupation monitoring element 1022 is used to monitor whether the coupler body 101 is in a service occupation state, and if so, send service occupation state information to the monitoring device;

[0126] In this embodiment, the service occupancy monitoring element is used to monitor whether a patch cord plug carrying a service is inserted into the coupler body. If it is detected that a patch cord plug carrying a service is inserted into the coupler body, it can be detected that the coupler body is in a service occupancy state, and service occupancy state information is sent to the monitoring device to inform the monitoring device that the coupler body is in a service occupancy state.

[0127] Case 3:

[0128] In one embodiment of the present invention, when the at least one occupancy monitoring element 102 includes a jumper fiber occupancy monitoring element 1021 and a service occupancy monitoring element 1022,

[0129] The jumper fiber occupancy monitoring element is used to monitor whether the coupler body is in a jumper fiber occupancy state, and if so, send jumper fiber occupancy state information to the monitoring device, so that the monitoring device triggers the service occupancy monitoring element according to the jumper fiber occupancy state information;

[0130] The service occupancy monitoring element is used to monitor whether the coupler body is in a service occupancy state when the monitoring device is triggered by the jumper occupancy state information; if yes, send the service occupancy state information to the monitoring device.

[0131] In this embodiment, based on determining that the coupler body is in a fiber jumper occupied state, if it is necessary to further determine whether the coupler body is occupied by a fiber jumper plug carrying a service, a fiber jumper occupancy monitoring element and a service occupancy monitoring element need to be provided in the optical fiber coupler.

[0132] Case 4:

[0133] In one embodiment of the present invention, when the at least one occupancy monitoring element 102 includes a jumper fiber occupancy monitoring element 1021 and a service occupancy monitoring element 1022,

[0134] The jumper fiber occupancy monitoring element 1021 is used to monitor whether the coupler body 101 is in a jumper fiber occupancy state, and if so, send jumper fiber occupancy state information to the monitoring device;

[0135] The service occupation monitoring element 1022 is used to monitor whether the coupler body 101 is in a service occupation state, and if so, send service occupation state information to the monitoring device.

[0136] In this embodiment, when the optical fiber coupler includes both the jumper occupancy monitoring element 1021 and the service occupancy monitoring element 1022, the user can use the monitoring device to trigger any one of the occupancy monitoring elements in a targeted manner. For example, when the user needs to know whether the optical fiber coupler is in a service occupancy state, the service occupancy monitoring element can be triggered separately.

[0137] In one embodiment of the present invention, the specific types of the jumper fiber occupancy monitoring element and the service occupancy monitoring element can be determined according to service requirements.

[0138] In this embodiment, the jumper fiber occupancy monitoring element is a current occupancy monitoring element, and the service occupancy monitoring element is a first optical detection element, wherein the first optical detection element is used to detect an optical signal with a wavelength within a first wavelength range.

[0139] In this embodiment, the first wavelength range can be determined according to the service requirements. For example, when a patch cord plug carrying a service is inserted into the optical fiber coupler, the patch cord plug usually emits an optical signal with a wavelength of 1310nm or 1550nm in the coupler body. Therefore, in order to distinguish the wavelength from the optical signal emitted by the patch cord plug itself, the first wavelength range can be set to any one of 1200nm to 1600nm, 1300nm to 1350nm, and 1500nm to 1570nm.

[0140] In addition, it should be noted that when the wavelength of the optical signal transmitted by the patch cord plug in the coupler body is not 1310 nm or 1550 nm, the first wavelength range may cover the wavelength of 1310 nm or 1550 nm.

[0141] In this embodiment, other types of jumper fiber occupancy monitoring elements may also be selected according to service requirements, such as capacitor occupancy monitoring elements, electromagnetic occupancy monitoring elements, etc.

[0142] In one embodiment of the present invention, the jumper fiber occupancy monitoring element 1021 includes a current occupancy monitoring element 1021A;

[0143] The current occupancy monitoring element 1021A is used to monitor whether a patch cord plug is inserted into the coupler body 101 under the triggering of the monitoring device; if yes, send the patch cord occupancy status information to the monitoring device.

[0144] In this embodiment, the current occupancy monitoring element 1021A includes at least one cathode metal contact 1021A1 and at least one anode metal contact 1021A2;

[0145] The at least one anode metal contact 1021A2 is used to receive the current transmitted by the monitoring device;

[0146] The at least one cathode metal contact 1021A1 is used to conduct with the at least one anode metal contact 1021A2 when the patch cord plug is inserted into the coupler body 101, and transmit the current back to the monitoring device; wherein the current transmitted back to the monitoring device is the patch cord occupancy status information.

[0147] In this embodiment, the type and quantity of the cathode metal contact and the anode metal contact can be determined according to business requirements. For example, considering that the cathode metal contact and the anode metal contact may be damaged during use, resulting in the inability to transmit current, a redundant design can be adopted for the cathode metal contact and the anode metal contact, setting two or more cathode metal contacts and setting two or more anode metal contacts.

[0148] In this embodiment, if Figure 2 As shown ( Figure 2 The type of coupler body shown in the figure is only an example. In actual application, the type of coupler body can be determined according to business requirements). The cathode metal contact and the anode metal contact are designed redundantly. The optical fiber coupler includes two cathode metal contacts 1021A1 and anode metal contacts 1021A2.

[0149] In this embodiment, the monitoring process of the current occupancy monitoring element is described below: Figure 3 As shown ( Figure 3The type of the coupler body shown in the figure is only an example. In actual application, the type of the coupler body can be determined according to business requirements. The current occupancy monitoring element 1021A includes a cathode metal contact 1021A1 and an anode metal contact 1021A2. The anode metal contact and the cathode metal contact are respectively connected to the monitoring device.

[0150] The anode metal contact 1021A2 receives the current transmitted by the monitoring device along the track a. When the jumper plug is inserted into the N end of the coupler body 101, the anode metal contact 1021A2 is connected to the cathode metal contact 1021A1. Then the cathode metal contact 1021A1 transmits the current back to the monitoring device along the track b. The monitoring device can learn that the optical fiber coupler is in the jumper occupied state based on the received return current.

[0151] The anode metal contact 1021A2 receives the current transmitted by the monitoring device along the track a. However, when the jumper plug is not inserted into the N end of the coupler body 101, the anode metal contact 1021A2 cannot be connected to the cathode metal contact 1021A1. Therefore, the cathode metal contact 1021A1 cannot receive the current in the anode metal contact 1021A2, and thus cannot return the current to the monitoring device. Therefore, when the monitoring device does not receive the return current, it is known that the optical fiber coupler is not in the jumper occupied state.

[0152] According to the above embodiment, when the cathode metal contact and the anode metal contact are inserted into the fiber jumper plug in the coupler body, the anode metal contact and the cathode metal contact can be connected. After the connection, through the cooperation between the cathode metal contact and the anode metal contact, the current transmitted by the monitoring device can be returned to the monitoring device to inform the monitoring device that the optical fiber coupler is in the fiber jumper occupied state. Therefore, the cathode metal contact and the anode metal contact can be used to accurately monitor whether the optical fiber coupler is in the occupied state.

[0153] In one embodiment of the present invention, the coupler body 101 includes a sleeve 1011 provided with a notch;

[0154] The current occupancy monitoring element 1021A includes at least one cathode metal contact 1021A1 and at least one anode metal contact 1021A2;

[0155] The at least one cathode metal contact 1021A1 and the at least one anode metal contact 1021A2 are both disposed outside the sleeve, and the at least one cathode metal contact 1021A1 and the at least one anode metal contact 1021A2 are not in contact with each other;

[0156] The at least one cathode metal contact 1021A1 and the at least one anode metal contact 1021A2 are both connected to the monitoring device.

[0157] In this embodiment, the cathode metal contact and the anode metal contact are both arranged outside the sleeve. For example, each metal contact can be directly arranged on the outer wall surface of the sleeve, or can be arranged at a position with a certain distance from the outer wall surface of the sleeve.

[0158] In this embodiment, in order to avoid erroneous monitoring caused by a short circuit between the anode metal contact and the cathode metal contact, the anode metal contact and the cathode metal contact are arranged so as not to contact each other.

[0159] In this embodiment, an example is given: Figure 4 is a bottom view of a fiber coupler (the invisible parts in the figure are represented by dotted lines, and Figure 4 The type of coupler body shown in is only an example. In actual application, the type of coupler body can be determined according to business requirements. Figure 4 It can be seen from the figure that the optical fiber coupler includes a cathode metal contact 1021A1 and an anode metal contact 1021A2, and the anode metal contact and the cathode metal contact are both arranged outside the sleeve 1011. There is a set distance between the anode metal contact and the cathode metal contact and the outer wall surface V of the sleeve 1011. In addition, from Figure 4 It can also be seen that in order to avoid a short circuit between the anode metal contact and the cathode metal contact, which may lead to erroneous monitoring, the cathode metal contact and the anode metal contact are not in contact with each other.

[0160] In this embodiment, in order to better illustrate the shapes of the anode metal contact and the cathode metal contact and the relative positions between the metal contacts and the sleeve, Figure 5 Take this as an example to illustrate ( Figure 5 The type of coupler body shown in is only an example. In actual applications, the type of coupler body can be determined according to business requirements). Figure 5 Figure 1 is an exploded view of a fiber coupler including an anode metal contact and a cathode metal contact. Figure 5 The shapes of the anode metal contact and the cathode metal contact shown in the figure are only one embodiment, and metal contacts of other shapes may be selected according to business requirements.

[0161] In one embodiment of the present invention, the number of the at least one cathode metal contact 1021A1, the number of the at least one anode metal contact 1021A2, and the circumference of the outer wall of the sleeve 1011 satisfy formula (1);

[0162] k×L=n×D+(n-1)×E+m×T+(m-1)×F+2S (1)

[0163] Among them, L represents the circumference of the outer wall of the sleeve; n represents the number of the cathode metal contacts, and n≥1; E represents the pre-set distance between any two adjacent cathode metal contacts; D represents the width of the cathode metal contact; m represents the number of the anode metal contacts, and m≥1; F represents the pre-set distance between any two adjacent anode metal contacts; T represents the width of the anode metal contact; S represents the distance between any two adjacent cathode metal contacts and anode metal contacts; k represents the margin coefficient, and k≥1.

[0164] In this embodiment, the margin coefficient k can be determined according to business requirements. The distance between the metal contact and the outer wall of the sleeve increases with the increase of the margin coefficient. When the metal contact needs to be closer to the outer wall of the sleeve, a margin coefficient with a smaller value can be selected. When the metal contact needs to be farther from the outer wall of the sleeve, a margin coefficient with a larger value can be selected.

[0165] In this embodiment, an example is given: Figure 6 As shown ( Figure 6 The type of coupler body shown in the figure is only an example. In actual application, the type of coupler body can be determined according to business requirements. Figure 6 It can be seen that there are two cathode metal contacts 1021A1 and two anode metal contacts 1021A2 in the optical fiber coupler. The distance between the two cathode metal contacts 1021A1 is E; the distance between the two anode metal contacts 1021A2 is F; the distance between any two adjacent cathode metal contacts 1021A1 and anode metal contacts 1021A2 is S; the widths of each anode metal contact 1021A2 and each cathode metal contact 1021A1 are the same, n; the circumference of the outer wall surface V of the sleeve is L. The margin coefficient k is determined based on the distance L1 between the metal contact and the outer wall surface of the sleeve. When any of the above parameters is an unknown quantity, the unknown quantity can be accurately determined based on other parameters.

[0166] In one embodiment of the present invention, the service occupancy monitoring element 1022 includes a first light detection element 1022A;

[0167] The first optical detection element 1022A is used to monitor whether there is an optical signal with a wavelength within a first wavelength range in the coupler body 101, and if so, send light information to the monitoring device; wherein the light information is the service occupancy status information.

[0168] In this embodiment, when the patch cord plug inserted into the coupler body is a patch cord plug for carrying services of transmission signals, the patch cord plug will emit an optical signal with a wavelength of 1310nm or 1550nm. Therefore, the first optical detection element can be used to monitor whether there is an optical signal with a wavelength within the first wavelength range in the coupler body.

[0169] If an optical signal within the first wavelength range is detected in the coupler body, it means that the patch cord plug inserted into the coupler body is carrying services. The coupler body is in a service occupied state, and the first optical detection element will send optical information to the monitoring device, so that the monitoring device determines that the optical fiber coupler is in a service occupied state according to the optical information.

[0170] If no optical signal within the first wavelength range is detected in the coupler body, it means that no fiber jumper plug is inserted into the coupler body, or the fiber jumper plug inserted into the coupler body does not carry any service.

[0171] According to the above embodiment, when the optical fiber coupler includes the first light detection element and a patch plug carrying services is inserted into the optical fiber coupler, it can be quickly detected that the optical fiber coupler is in a valid service occupation state.

[0172] In one embodiment of the present invention, the coupler body 101 includes a sleeve 1011 provided with a notch 1011A;

[0173] The first light detecting element 1022A includes at least one first light detector 1022A1;

[0174] Each of the first optical detectors 1022A1 faces the slot 1011A, and is used to detect an optical signal at the slot 1011A whose wavelength is within a first wavelength range.

[0175] In this embodiment, considering the situation that the first light detector is damaged during use, two or more first light detectors may be provided.

[0176] In this embodiment, in order to ensure that the first optical detector can quickly detect the optical signal with a wavelength within the first wavelength range, the first optical detector needs to be oriented toward the notch in the sleeve. Therefore, when the jumper plug carrying the service is inserted into the coupler body, the optical signal will pass through the notch.

[0177] In this embodiment, if Figure 7 As shown ( Figure 7 The type of coupler body shown in is only an example. In actual application, the type of coupler body can be determined according to business requirements). Figure 71 is a stereoscopic diagram of an optical fiber coupler. A first optical detector 1022A1 is arranged in the optical fiber coupler. The first optical detector is connected to the monitoring device through two pins P1 and P2. The first optical detector can send service occupation status information to the monitoring device through the two pins.

[0178] In this embodiment, in order to better illustrate the relative position of the first light detector and the notch of the sleeve, Figure 8 and Fig. 9 To explain ( Figure 8 and Fig. 9 The type of coupler body shown in is only an example. In actual application, the type of coupler body can be determined according to business requirements): wherein, Figure 8 This is a cross-sectional diagram of the fiber coupler from the top view. Fig. 9 Exploded diagram of a fiber coupler. Figure 8 and Fig. 9 It can be seen from the figure that the first light detector 1022A1 is facing the notch 1011A of the sleeve 1011.

[0179] According to the above embodiment, since the first light detector is facing the notch of the sleeve, the first light detector can quickly detect whether there is an optical signal with a wavelength within the first wavelength range in the coupler body.

[0180] In one embodiment of the present invention, the at least one occupancy monitoring element 102 includes the current occupancy monitoring element 1021A and the first light detection element 1022A;

[0181] The current occupancy monitoring element 1021A is used to send the patch cord occupancy status information to the monitoring device when it is detected that a patch cord plug is inserted into the coupler body 101, so that the monitoring device triggers the first light detection element according to the patch cord occupancy status information;

[0182] The first optical detection element 1022A is used to monitor whether the wavelength of the optical signal in the coupler body 101 is within the first wavelength range when the monitoring device is triggered by the fiber jumper occupancy status information. If so, send optical information to the monitoring device; wherein the optical information is the service occupancy status information.

[0183] In one embodiment of the present invention, the optical fiber coupler may further include a second light detection element 103;

[0184] The second optical detection element 103 is used to monitor whether there is an optical signal with a wavelength within the second wavelength range in the coupler body 101. If so, optical signal information corresponding to the optical signal is obtained and sent to the monitoring device, so that the monitoring device forms optical path detection information based on the optical signal information.

[0185] In this embodiment, the optical fiber coupler can include a second optical detection element, a jumper fiber occupancy monitoring element, and a service occupancy monitoring element at the same time. Not only can the jumper fiber occupancy status and service occupancy status be monitored, but also the optical signal information can be obtained, so that the monitoring device can form optical path detection information according to the optical signal information and obtain the optical path routing.

[0186] In this embodiment, the second light detecting element may include at least one second light detector. For example, when considering the damage of the second light detector, two or more second light detectors may be provided. When considering the cost, one second light detector may be provided.

[0187] In this embodiment, the second wavelength range can be determined according to the service requirements. For example, when the jumper plug carrying the service sends an optical signal with a wavelength of 1310nm or 1550nm, the second wavelength range can be a wavelength range that does not include 1310nm or 1550nm. For example, the second wavelength range can be 900nm to 1100nm, 1900nm to 3000nm.

[0188] like Fig.10 As shown ( Fig.10 The type of coupler body shown in the figure is only an example. In actual applications, the type of the coupler body can be determined according to business requirements). The optical fiber coupler also includes a second optical detection element (second optical detector 103), a jump fiber occupancy monitoring element (cathode metal contact 1021A1 and anode metal contact 1021A2) and a business occupancy monitoring element (first optical detector 1022A1).

[0189] In this embodiment, the optical fiber coupler can include a second optical detection element and a jumper fiber occupancy monitoring element at the same time, which can not only monitor the jumper fiber occupancy status, but also obtain optical path characteristic information, so that the monitoring device can form optical path detection information according to the optical path characteristic information and obtain the optical path route.

[0190] like Fig.11 As shown ( Fig.11 The type of coupler body shown in the figure is only an example. In actual application, the type of coupler body can be determined according to business requirements). The optical fiber coupler also includes a second optical detection element (second optical detector 103) and a jump fiber occupancy monitoring element (cathode metal contact 1021A1 and anode metal contact 1021A2).

[0191] In this embodiment, the optical fiber coupler can include a second optical detection element and a service occupancy monitoring element at the same time, which can not only monitor the service occupancy status, but also obtain optical signal information, so that the monitoring device can form optical path detection information according to the optical signal information and obtain the optical path route.

The optical fiber coupler also includes a second optical detection element (second optical detector 103) and a business occupancy monitoring element (first optical detector 1022A1).

[0193] In this embodiment, when the second optical detection element detects that there is an optical signal with a wavelength within the second wavelength range in the coupler body, optical signal information corresponding to the optical signal is obtained. The optical signal information may include but is not limited to the optical frequency and the encoding of the set length. The optical signal information is then sent to the monitoring device so that the monitoring device parses the optical frequency and the encoding of the set length, thereby forming optical path detection information that can be determined, and the upstream optical fiber coupler connected to the optical fiber coupler or the downstream optical fiber coupler connected to the optical fiber coupler can be obtained from the optical path detection information.

[0194] In this embodiment, the second light detection element may include at least one second light detector. In order to ensure that the second light detector can quickly detect the light signal with a wavelength within the second wavelength range, the second light detector needs to be directed toward the slot in the sleeve. Because when the coupler body receives the light signal with a wavelength within the second wavelength range, the light signal will pass through the slot.

[0195] According to the above embodiment, when the second optical detection element detects that there is an optical signal with a wavelength within the preset second wavelength range in the coupler body, it obtains the optical signal information corresponding to the optical signal and sends the optical signal information to the monitoring device, so that the monitoring device forms optical path detection information based on the optical signal information. In this way, the optical path where the optical fiber coupler is located can be quickly determined.
