Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber network transmission operation and maintenance management, in particular to a light guide rod with a built-in optical sensor. Background Art
[0002] The quality of the connection points of tens of billions of optical fibers has the greatest impact on high-bandwidth transmission, because each optical path has more than five active optical fiber connection points, and there is a fusion point every two kilometers. Any abnormal loss at any connection point will affect the transmission bandwidth.
[0003] At present, optical power and OTDR optical time domain reflectometers are used in the construction of optical networks, optical attenuation control and emergency repair. The optical power of active connection points is detected, or the entire optical path is detected from the source or the end of the optical path, and the length and distance value of the loss abnormal point is given. Due to the redundancy of optical cable layout, the distance value given by the instrument cannot accurately locate the abnormal point, and often relies on line workers to inefficiently investigate. In addition, inspectors cannot find degraded connection points and eliminate connection risks through daily inspections when the connection points are online (uninterrupted), which has become a long-standing problem that needs to be solved in the field of optical communications.
[0004] The existing solution of setting a transparent light guide rod at the connection point realizes the function of route search by injecting visible red light into the optical path and exporting the overflowed red light of the connection point, but cannot detect the quality of the connection point; among the solutions of setting optical sensors at the connection point, one adopts the slotted light splitting technology set at the connection point to realize the route search function by analyzing the transmitted light information, and the other injects visible red light to judge the quality of the connection point. However, due to the excessive attenuation of visible red light in the optical fiber line, the judgment result is inaccurate and difficult to be applied in practice.
[0005] Here, a solution of setting up optical sensors on the connection points to detect the overflowed transmission light is adopted. Since the better the connection quality of the connection points, the weaker the overflowed transmission light, the greater the impact of the sensitivity and damage of the optical sensors on the detection results. What needs to be solved in reality is how to determine whether the working status of the optical sensor is normal or not, and how to determine whether the sensitivity of the optical sensor meets the requirements. Only in this way can the detection results be accurate and can it be applied to the production and maintenance of the fiber optic network connection points.
[0006] There is currently no such program. Utility Model Content

[0034] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0037] In practice, each optical fiber route in a general transmission optical network is connected by multiple connection points 400, which are divided into active connection points, fusion connection points, and mechanical (cold connection) connection points. Some of the fiber splicing trays 500 are only provided with fusion connection points, and some are provided with fusion connection points or mechanical (cold connection) connection points and active connection points. Each fiber splicing tray 500 is provided with multiple routing ports in parallel on the outside, and the routing port is formed by an optical fiber flange adapter 300 and an internally connected active connection point 400. The present utility model takes the active connection point 400 at the routing port as an example for illustration. It should be noted here that other types of connection points are also suitable for this solution, which is achieved by simply setting a light extraction port 301 on the protective box cover of the cold connection point and the fusion point, and installing the light guide rod with a built-in optical sensor of the present utility model. Example 1
[0038] In this implementation, Figures 1 to 4 One embodiment of a light guide rod with a built-in light sensor is shown. Specifically, the light guide rod with a built-in light sensor includes a rod body 100 and a light sensor 200. The rod body 100 is composed of a rod head 101 and a rod tail 102, and the light sensor 200 is arranged at the interface between the rod head 101 and the rod tail 102. The rod head 101 is provided with a first light sensing channel 101a, and the rod tail 102 is provided with a second light sensing channel 102a.
[0039] Specifically, the optical sensor 200 includes a photosensitive surface 201 and positive and negative electrode pins 202. The positive and negative electrode pins 202 are provided with electrical contacts 202a.
[0040] Furthermore, the first photosensitive channel 101a is communicated with the second photosensitive channel 102a and is integrally injection-molded with the rod body 100. The rod body 100 is also provided with a groove 102b in which the electrical contact 202a is embedded.
[0041] Preferably, the second photosensitive channel 102a is a curved channel.
[0042] Obviously, the outer end face of the first photosensitive channel 101a is the first incident face 101b, and the outer end face of the second photosensitive channel 102a is the second incident face 102g. The transmission light overflowing from the connection point 300 is incident from the first incident face 101b, and a part of the transmission light is irradiated on the photosensitive surface 201 through the first photosensitive channel 101a, and the other part of the transmission light passes through the gap of the photosensitive surface 201, passes through the second photosensitive channel 102a, and is emitted from the second incident face 102g.
[0043] It can be seen that if the overflowed transmission light is visible red light, it can be injected from the first photosensitive channel 101a, pass through the gap in the photosensitive surface 201, pass through the second photosensitive channel 102a, and be emitted from the second incident surface 102g to be observed. That is to say, after the built-in sensor of the utility model is built in, it does not affect the function of injecting visible red light to find the route.
[0044] Conversely, the self-test light is incident from the second incident surface 102g, part of the self-test light passes through the second photosensitive channel 102a and illuminates the back of the photosensitive surface 201, another part of the self-test light passes through the gap in the photosensitive surface 201 and enters the first photosensitive channel 101a, and part of the self-test light is reflected by the first incident surface 101b and illuminates the photosensitive surface 201. That is to say, the built-in sensor of the utility model can receive self-test light information. Example 2
[0045] Figures 4 and 5 One embodiment of a light guide rod with a built-in optical sensor is shown. This embodiment is different from the above-mentioned embodiment 1 in that a hook 202aa is provided on the electrical contact 202a, and a hole 102c is correspondingly provided on the rod tail 102, and the hook 202aa is buckled in the hole 102c.
[0046] Furthermore, the positive and negative electrode pins 202 and the electrical contacts 202a are integrally formed by stamping and bending. By bending the positive and negative electrode pins 202, the hooks 202aa are inserted into the holes 102c, so that the electrical contacts 202a are embedded in the grooves 102b. Example 3
[0047] Figures 4 to 6 One embodiment of a light guide rod with a built-in light sensor is shown. This embodiment is different from the above-mentioned embodiment 2 in that the rod tail 102 is also symmetrically provided with a buckle plate 102d. After the rod head 101 is inserted into the light intake port 301 on the flange adapter 300, two centrally symmetrical snap-in hooks 302 distributed on the periphery of the light intake port 301 are screwed together.
[0048] Specifically, light intake ports 301 are provided on different flange adapters 300, and centrally symmetrical snap-in hooks 302 are distributed around the light intake ports 301. This solution has been involved in previous patents and will not be elaborated here. Obviously, the utility model can continuously replace ordinary light guide rod assemblies and realize rapid upgrade of the connection points 400. Example 4
[0049] Figures 6 to 9 One embodiment of a light guide rod with a built-in optical sensor is shown. This embodiment is different from the above-mentioned embodiment 2 in that the rod tail 102 is spliced by a straight tail 102e and a bent tail 102f, and a buckle plate 102d is arranged on the bent tail 102f.
[0050] Specifically, the straight tail 102e and the bent tail 102f are spliced by light guide glue.
[0051] Preferably, the first photosensitive channel 101a and the second photosensitive channel 102a are made of light-transmitting materials, such as acrylic.
[0052] Preferably, the club head 101, the club butt 102 and the gusset 102d are made of opaque material.
[0053] In the present invention, the first light collecting unit 200 can also be replaced with a photosensitive diode to capture and collect weak overflow light and provide feedback to the user, thereby forming a photon tag for the routing port and realizing automatic routing search of the optical fiber line.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
