Technical Field

The invention relates to the technical field of optical fibers, in particular to an optical fiber coupler, a monitoring system and an occupation state monitoring method.

Background

With the development of communication technology, optical fiber networks of telecom operators are deployed more and more widely. The optical fiber is deployed in segments. These sectionally deployed fibers are typically connected into a service light path using fiber couplers. Optical fiber networks have the advantages of low cost and large bandwidth, but since the entire network is in a "passive" state except for the communication devices at the initial end (a-end) and the final end (Z-end), the network is referred to as "dumb resources" in the industry.

At present, network maintenance personnel usually perform fiber skipping according to an optical path service work order, and connect the optical fibers deployed in segments into a complete service optical path by using an optical fiber coupler and the skipped optical fibers. When the occupation state of each optical fiber coupler needs to be monitored, the occupation state can be monitored only through service work order data due to the characteristic of the dummy resource. However, when the network maintenance staff completes the service optical path according to the optical path service work order, due to individual differences among the network maintenance staff, a large amount of fiber jumping operations are not performed according to requirements on the service work order, which results in a huge difference between the actual occupation of the optical fiber coupler and the service work order data, according to experience data in the industry, the coincidence rate of the service work order data and the field occupation is only 60%, and meanwhile, the network management department has no sufficient human resources to discover the difference in time. The difference makes operators unable to master the use condition of network resources, and the existing network resources cannot be fully utilized, thereby causing a great deal of network resource waste; meanwhile, the discrepancy between the business work order data and the actual situation on site also causes low efficiency of network fault removal, low speed of opening new business and low user satisfaction rate.

Therefore, when the occupation condition of each optical fiber coupler is monitored by adopting the service work order data, the real occupation state of part of the optical fiber couplers cannot be reflected. Therefore, the existing method has low accuracy in monitoring the occupancy state of the optical fiber coupler.

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in fig. 1, an embodiment of the present invention provides an optical fiber coupler, including:

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;

each of the occupancy monitoring elements 102 is configured to monitor whether the coupler body 101 is in an occupied state, and if so, send occupancy state information to an external monitoring device.

According to the embodiment shown in FIG. 1, 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 monitoring that the coupling body is in the occupation state, the monitoring device sends occupation state information to the external monitoring device, so that the monitoring device can know the occupation condition of the optical fiber coupler in time according to the occupation state information. Therefore, in the embodiment of the invention, because the occupancy monitoring element is located in the coupler body, the real occupancy state of the coupler body can be accurately monitored. Therefore, the scheme provided by the embodiment of the invention can improve the accuracy of monitoring the occupation state of the optical fiber coupler.

In one embodiment of the present invention, the fiber coupler shown in FIG. 1 is merely an example. The type of the coupler body and the type of the occupancy monitoring element can be determined according to the service requirements. The coupler body shown in fig. 1 is an FC type coupler body and includes two types of occupancy-monitoring elements.

In one embodiment of the present invention, the specific type of the coupler body 101 shown in fig. 1 can be determined according to the service requirement. Generally alternatively, the coupler body may 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.

In this embodiment, if there is a specific service requirement, the coupler body may be any one of an MTRJ type adapter body, an MPO type adapter body, and an E2000 type adapter body.

According to the above embodiment, 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 the service requirement. Therefore, the service applicability is strong.

In one embodiment of the present invention, the at least one occupancy monitoring element 102 may include a fiber hop occupancy monitoring element 1021 and/or a traffic occupancy monitoring element 1022.

In this embodiment, the type of occupancy monitoring element may be selected according to specific traffic requirements. For example, when only the fiber skipping occupation state of the coupler body needs to be monitored, a fiber skipping occupation monitoring element can be selected; when the service occupation state of the coupler body is only required to be monitored, a service occupation monitoring element can be selected; when the fiber skipping occupation state of the coupler body and the service occupation state need to be monitored, a fiber skipping occupation monitoring element and a service fiber skipping occupation monitoring element can be selected and used at the same time.

In this embodiment, when the fiber jumper plug is inserted into the coupler body, the fiber jumper occupancy monitoring element can monitor that the coupler body is in an occupied state regardless of whether the fiber jumper plug carries a service or not.

In this embodiment, when the fiber jumper plug is inserted into the coupler body and the fiber jumper plug carries a service, the service occupancy monitoring element may monitor that the outcoupling body is in an occupied state.

According to the above embodiment, the occupancy monitoring element may include one or both of a fiber hop occupancy monitoring element and a service occupancy monitoring element according to the service requirement. Therefore, the service applicability is strong.

If it is monitored that the fiber jumping plug is inserted into the coupler body, the fiber jumping occupation state of the coupler body can be monitored, and fiber jumping occupation state information is sent to the monitoring device to inform the monitoring device that the coupler body is in the fiber jumping occupation state.

Case two:

In this embodiment, on the basis of determining that the coupler body is in the fiber skipping occupation state, when it is necessary to further determine whether the coupler body is occupied by a fiber skipping plug carrying a service, the fiber skipping occupation monitoring element and the service occupation monitoring element need to be simultaneously disposed in the optical fiber coupler.

Case four:

in one embodiment of the present invention, when the at least one occupancy monitoring element 102 comprises a fiber hop occupancy monitoring element 1021 and a traffic occupancy monitoring element 1022,

the fiber skipping occupation monitoring element 1021 is used for monitoring whether the coupler body 101 is in a fiber skipping occupation state or not, and if yes, sending fiber skipping occupation state information to the monitoring device;

the service occupancy monitoring element 1022 is configured to monitor whether the coupler body 101 is in a service occupancy state, and if so, send service occupancy state information to the monitoring device.

In this embodiment, when both the fiber jump occupancy monitoring element 1021 and the traffic occupancy monitoring element 1022 are included in the fiber coupler, a user can use the monitoring device to specifically trigger any of the occupancy monitoring elements. For example, when a user needs to know whether the optical fiber coupler is in a service occupancy state, the service occupancy monitoring element may be triggered separately.

In an embodiment of the present invention, the specific types of the fiber hop occupancy monitoring element and the service occupancy monitoring element can be determined according to service requirements.

In this embodiment, the fiber jump occupancy monitoring element is a current occupancy monitoring element. The service occupancy monitoring element is a first optical detection element. Wherein the first light detecting element is adapted to detect light signals having a wavelength in a first wavelength range.

In this embodiment, the first wavelength range may be determined according to the service requirement, for example, because when a service-carrying jumper plug is inserted into the optical fiber coupler, the jumper plug will generally radiate an optical signal with a wavelength of 1310nm or 1550nm in the coupler body. Therefore, in order to distinguish the wavelength from the wavelength of the optical signal emitted from the jumper fiber plug itself, the first wavelength range may be set to any one of 1200nm to 1600nm, 1300nm to 1350nm, and 1500nm to 1570 nm.

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

In this embodiment, other types of jump fiber occupancy monitoring elements may also be selected according to the service requirement. Such as capacitive occupancy monitoring elements, electromagnetic occupancy monitoring elements, and the like.

In one embodiment of the present invention, the fiber jump occupancy monitoring element 1021 comprises a current occupancy monitoring element 1021A;

the current occupancy monitoring element 1021A is used for monitoring whether a fiber jumper plug is inserted into the coupler body 101 or not under the triggering of the monitoring device; and if so, sending the jump fiber occupation state information to the monitoring device.

In the present embodiment, the current occupancy monitoring element 1021A includes at least one cathode metal contact 1021A1 and at least one anode metal contact 1021A 2;

the at least one anode metal contact 1021A2 is used for receiving the current transmitted by the monitoring device;

the at least one cathode metal contact 1021A1 is used for conducting with the at least one anode metal contact 1021A2 when the jumper plug is inserted into the coupler body 101, so as to transmit the current back to the monitoring device; and the current returned to the monitoring device is the jump fiber occupation state information.

In the present embodiment, the types and the number of the cathode metal contacts and the anode metal contacts can be determined according to the business requirements. For example, the following steps are carried out: it is considered that the cathode metal contact and the anode metal contact may be damaged during use, thereby causing a situation where current transmission is disabled. It is thus possible to use a redundant design 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.

In the present embodiment, as shown in fig. 2 (the type of the coupler body shown in fig. 2 is only an example, and in practical applications, the type of the coupler body can be determined according to service requirements), the cathode metal contact and the anode metal contact are of a redundant design, and the optical fiber coupler includes two cathode metal contacts 1021a1 and two anode metal contacts 1021a 2.

In this embodiment, the following describes the monitoring process of the current occupancy monitoring element: as shown in fig. 3 (the type of the coupler body shown in fig. 3 is only an example, and in practical applications, the type of the coupler body can be determined according to service requirements), the current occupancy monitoring element 1021A includes a cathode metal contact 1021A1 and an anode metal contact 1021A 2. And the anode metal contact and the cathode metal contact are respectively connected with the monitoring device.

The current transmitted from the monitoring device is received at the anode metal contact 1021A2 along trace a. When a jumper plug is inserted into the N-terminal of the coupler body 101, the anode metal contact 1021a2 and the cathode metal contact 1021a1 are electrically connected. The cathode metal contact 1021A1 then transmits the current back to the monitoring device along trace b. So that the monitoring device can know that the optical fiber coupler is in a fiber jumping occupation state according to the received return current.

The current transmitted from the monitoring device is received at the anode metal contact 1021A2 along trace a. However, when no jumper plug is inserted into the N-terminal of the coupler body 101, the anode metal contact 1021a2 cannot be brought into conduction with the cathode metal contact 1021a 1. The cathode metal contact 1021A1 is unable to receive current from the anode metal contact 1021A2, and therefore unable to return current to the monitoring device. Therefore, when the monitoring device does not receive the return current, the monitoring device knows that the optical fiber coupler is not in the fiber jumping occupation state.

According to the embodiment, when the cathode metal contact and the anode metal contact are inserted into the jumper plug in the coupler body, the anode metal contact and the cathode metal contact can be conducted. After the optical fiber coupler is conducted, the current transmitted by the monitoring device can be transmitted back to the monitoring device through the mutual matching of the cathode metal contact and the anode metal contact, so that the optical fiber coupler of the monitoring device is informed of the state of the optical fiber coupler in the fiber jumping occupation state. Therefore, whether the optical fiber coupler is in an occupied state or not can be accurately monitored by utilizing the cathode metal contact and the anode metal contact.

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

the current occupancy monitoring element 1021A includes at least one cathode metal contact 1021A1 and at least one anode metal contact 1021A 2;

the at least one cathode metal contact 1021A1 and the at least one anode metal contact 1021A2 are both disposed outside of the sleeve, and the at least one cathode metal contact 1021A1 and the at least one anode metal contact 1021A2 are not in contact;

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

In this embodiment, both the cathode metal contact and the anode metal contact are disposed outside the sleeve. For example, the metal contacts may be disposed directly on the outer wall surface of the sleeve or may be disposed at a distance from the outer wall surface of the sleeve.

In this embodiment, in order to avoid a situation where erroneous monitoring occurs due to short-circuiting of the anode metal contact and the cathode metal contact, the anode metal contact and the cathode metal contact are not in contact with each other when they are arranged.

In the present embodiment, the following are exemplified: fig. 4 is a bottom view of a fiber coupler (the invisible part is shown by dashed lines, and the type of coupler body shown in fig. 4 is only an example, and the type of coupler body can be determined according to service requirements in practical application). As can be seen from fig. 4, the fiber coupler includes a cathode metal contact 1021a1 and an anode metal contact 1021a2, both of which are disposed outside of the sleeve 1011. The anode metal contact and the cathode metal contact are both at a predetermined distance from the outer wall surface V of the sleeve 1011. In addition, it can be seen from fig. 4 that the cathode metal contact and the anode metal contact are not in contact with each other in order to avoid the situation that the anode metal contact and the cathode metal contact are short-circuited to cause false monitoring.

In this embodiment, in order to better describe the shapes of the anode metal contact and the cathode metal contact and the relative positions between the metal contacts and the sleeve, the following description is made by taking fig. 5 as an example (the type of the coupler body shown in fig. 5 is only an example, and in practical applications, the type of the coupler body can be determined according to business requirements). Fig. 5 is an exploded view of a fiber optic coupler including an anodic metal contact and a cathodic metal contact. It is noted that the shape of the anode metal contact and the cathode metal contact shown in fig. 5 is only one example, and other shapes of metal contacts may be selected according to business requirements.

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 surface of the sleeve 1011 satisfy formula (1);

k×L＝n×D+(n-1)×E+m×T+(m-1)×F+2S (1)

wherein L represents a perimeter of an outer wall surface of the casing; the n represents the number of the cathode metal contacts, and n is more than or equal to 1; the E represents the preset distance between any two adjacent cathode metal contacts; the D represents the width of the cathode metal contact; the m represents the number of the anode metal contacts, and is more than or equal to 1; the F represents the preset distance between any two adjacent anode metal contacts; the T represents the width of the anode metal contact; the S represents the distance between any two adjacent cathode metal contacts and anode metal contacts; and k represents a margin coefficient, and k is more than or equal to 1.

In this embodiment, the margin coefficient k may be determined according to the traffic requirement. The distance between the metal contact and the outer wall surface of the sleeve increases with increasing margin factor. When the metal contact is required to be closer to the outer wall surface of the sleeve, a margin coefficient with a smaller value can be selected. When the metal contact is required to be far away from the outer wall surface of the sleeve, a margin coefficient with a larger value can be selected.

In the present embodiment, the following are exemplified: as shown in fig. 6 (the type of coupler body shown in fig. 6 is only an example, and the type of coupler body in practical application can be determined according to service requirements), it can be seen from fig. 6 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; each anode metal contact 1021a2 and each cathode metal contact 1021a1 have the same width n; the circumference of the outer wall surface V of the sleeve is L. And determining a margin coefficient k according to the distance L1 between the metal contact and the outer wall surface of the sleeve. When any one of the parameters is an unknown quantity, the unknown quantity can be accurately determined according to other parameters.

In one embodiment of the present invention, the traffic occupancy monitoring element 1022 includes a first optical detection element 1022A;

the first optical detection element 1022A is configured to monitor whether an optical signal with a wavelength within a first wavelength range exists in the coupler body 101, and if so, send optical information to the monitoring device; wherein the presence information is the service occupation state information.

In this embodiment, when the patch cord plug inserted into the coupler body is a service-carrying patch cord plug for transmitting signals, the patch cord plug may emit optical signals with a wavelength of 1310nm or 1550 nm. Thus, the presence of an optical signal having a wavelength within the first wavelength range in the coupler body can be monitored by means of the first optical detection element.

And if the optical signal in the first wavelength range exists in the coupler body, indicating that the jumper plug inserted into the coupler body is carrying the service. The coupler body is in a service occupation state, and at the moment, the first optical detection element sends optical information to the monitoring device, so that the monitoring device determines that the optical fiber coupler is in the service occupation state according to the optical information.

If the optical signal in the first wavelength range is not monitored in the coupler body, it indicates that no jumper fiber plug is inserted into the coupler body, or that the jumper fiber plug inserted into the coupler body does not carry service.

According to the embodiment, when the optical fiber coupler comprises the first optical detection element and a service-bearing fiber jumper plug is inserted into the optical fiber coupler, the optical fiber coupler can be rapidly monitored to be in an effective service occupation state.

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

the first light detecting element 1022A includes at least one first light detector 1022A 1;

each of the first light detectors 1022a1 faces the notch 1011A for detecting light signals at the notch 1011A having wavelengths in a first wavelength range.

In this embodiment, two or more first photodetectors may be provided in consideration of the fact that the first photodetector is damaged during use.

In this embodiment, to ensure that the first light detector can rapidly detect the light signal with the wavelength in the first wavelength range, the first light detector needs to be directed to the notch in the casing. Thus, when a service-carrying jumper plug is inserted into the coupler body, the optical signal will pass out through the notch.

In the present embodiment, as shown in fig. 7 (the type of the coupler body shown in fig. 7 is only an example, and the type of the coupler body in practical application can be determined according to service requirements), fig. 7 is a perspective view of a fiber coupler. A first photo detector 1022a1 is disposed in the fiber coupler. The first light detector is connected with the monitoring device through two pins P1 and P2. And can send the service occupation status information to the monitoring device through the two pins.

In this embodiment, in order to better illustrate the relative positions of the first optical detector and the slot of the sleeve, fig. 8 and 9 are used for the following description (the type of the coupler body shown in fig. 8 and 9 is only an example, and in practical applications, the type of the coupler body can be determined according to the service requirement): fig. 8 is a schematic cross-sectional view of the fiber coupler in a top view, and fig. 9 is an exploded schematic view of the fiber coupler. It can be seen from fig. 8 and 9 that the first light detector 1022a1 is directed toward the notch 1011A of the sleeve 1011.

For example, two or more second photodetectors may be provided in consideration of the damage condition of the second photodetector. A second photodetector may be provided when cost is a concern.

For example, when the service-carrying jumper plug emits an optical signal with a wavelength of 1310nm or 1550nm, the second wavelength range may be a wavelength range excluding 1310nm or 1550 nm. For example, the second wavelength range may be 900nm to 1100nm, 1900nm to 3000 nm.
