Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fiber optic network transmission operation and maintenance management, and in particular to a light guiding device with a built-in optical sensor. Background Technology
[0002] Currently, optical power and OTDR (Optical Time Domain Reflectometer) are used in the construction, attenuation treatment, and emergency repair of optical networks. These instruments detect the optical power at active connection points when the network is interrupted, or inspect the entire optical path from the source or end, providing the distance value of the point of abnormal loss. However, due to the redundancy in the optical cable layout, the distance value provided by the instruments cannot accurately locate the anomaly, often relying on line workers for inefficient investigation. Furthermore, inspectors cannot identify degraded connection points and eliminate potential connection problems through routine inspections while the connection is still operational (without network interruption). This has become a long-standing and pressing problem in the field of optical communication.
[0003] The existing solution involves setting a light guide rod with a built-in light sensor at the connection point. The light sensor is directly built into the light guide rod, and external contacts are set on the positive and negative pins. The light guide rod is then directly mounted on the adapter. Although this solution reduces one internal contact, the external contact and the positive and negative pins are integrally stamped and formed. The size of the external contact is small, which leads to poor contact when it is snapped into the instrument in the field. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0015] In a preferred embodiment of the light guiding device with built-in light sensor described in this utility model, the first light-sensing channel and the second light-sensing channel are made of light-transmitting material.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "an 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0029] In practice, each fiber optic route in a typical optical transmission network is connected by multiple connection points 500, which are divided into active connection points, fusion splice connection points, and mechanical (cold splice) connection points. Some fusion splice trays only have fusion splice connection points, while others have fusion splice connection points, mechanical (cold splice) connection points, and active connection points. Multiple routing ports are arranged side-by-side on the outside of each fusion splice tray. Each routing port is formed by an optical fiber flange adapter 400 and an internal active connection point 500. This invention uses the active connection point 500 at the routing port as an example for illustration. It should be noted that other types of connection points are also suitable for this solution, simply by setting a light-gathering port 401 on the protective cover of the cold splice or fusion splice and installing the light-guiding device with the built-in optical sensor of this invention.
[0030] Example 1
[0031] In this implementation, Figures 1-4 One embodiment of a light guide device with a built-in light sensor is shown. Specifically, a light guide device with a built-in light sensor includes a light guide rod 100, an electrode plate 200, and a mounting base 300. The light guide rod 100 is composed of a rod body 101 and a light sensor 102.
[0032] The rod body 101 is composed of a rod head 101a and a rod tail 101b, and a light sensor 102 is disposed at the critical surface of the rod head 101a and the rod tail 101b; the rod head 101a is provided with a first light-sensing channel 101aa, and the rod tail 101b is provided with a second light-sensing channel 101ba.
[0033] Specifically, the light sensor 102 includes a photosensitive surface 102a and positive and negative electrode pins 102b;
[0034] Furthermore, the electrode plate 200 is provided with an inner contact 201 and an outer contact 202, wherein the inner contact 201 is in contact with the positive and negative electrode pins 102b for conductive communication.
[0035] Ideally, the mounting base 300 is provided with a rod cavity 301, an electrode cavity 302 and a buckle plate 303, and the light guide rod 100 and the electrical connection plate 200 are respectively pressed into the rod cavity 301 and the electrode cavity 302.
[0036] Excellent, the second photosensitive channel 101ba is a curved channel.
[0037] Obviously, see Figure 1 The light overflowing from the connection point 500 passes through the first photosensitive channel 101aa, part of which illuminates the photosensitive surface 102a, while the other part of the overflowing light passes through the gap in the photosensitive surface 102a and is emitted through the second photosensitive channel 101ba.
[0038] As can be seen, if the overflowing transmission light is visible red light, it can enter from the first photosensitive channel 101aa, pass through the gap of the photosensitive surface 102a, and exit through the second photosensitive channel 101ba, and be observed. That is to say, the built-in sensor of this utility model does not affect the function of injecting visible red light to find the route.
[0039] Conversely, the self-test light enters from the second photosensitive channel 101ba, part of which illuminates the back of the photosensitive surface 201, and the other part of the self-test light passes through the gap of the photosensitive surface 102a and enters the first photosensitive channel 101aa. After being reflected by the critical surface, it illuminates the photosensitive surface 102a. That is to say, the built-in sensor of this utility model can receive self-test light information.
[0040] Example 2
[0041] Figures 4-5 This embodiment illustrates one implementation of a light guide device with a built-in light sensor. Unlike Embodiment 1 described above, this embodiment also includes a locking hole 304 in the mounting base 300 and a boss 101c corresponding to the rod body 101. The light guide rod 100 and the electrode plate 200 are fixed in the mounting base 300 by engaging the locking hole 304 and the boss 101c. The inner contact 201 is in contact with the positive and negative electrode pins 102b for conductive communication.
[0042] Example 3
[0043] Figures 4-6 This invention illustrates one embodiment of a light guiding device with a built-in light sensor. This embodiment differs from Embodiment 2 above in that the external contact 202 is provided with a wiring hole 202a, which can be used to solder wires.
[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
