Description

Technical Field

[0001] The utility model mainly relates to the field of optical networks, and in particular to an optical fiber identification device and an optical fiber identification system. Background Art

[0002] As the network continues to develop, there are more and more fiber optic cabinets used to connect to the network. At the same time, the network services are increasing, and service changes are becoming more and more frequent. Therefore, it is necessary to understand the connection relationship of the fiber optic network in the computer room.

[0003] The application number of the prior art is CN201410393176.8, and its name is A method, device and system for determining optical network connection relationships. It discloses a light source device and an optical fiber identifier, wherein the light source device can inject a specific signal into the optical fiber, such as a DC optical signal or a signal of a specific frequency, and the optical fiber identifier provides an optical fiber slot to bend the optical fiber, and detects the leakage signal generated by the bending of the optical fiber, and determines whether the received signal is the signal injected into the optical fiber by the light source device. If so, it can be determined that the light source device and the optical fiber identifier are operating the same optical fiber. The specific usage process is that an operator connects the light source device to the optical fiber to be identified on the local side, and transmits a specific signal to the optical fiber for transmission, and at the same time informs the remote detection personnel of the signal transmitted this time. The remote detection personnel connects many optical fibers one by one to the optical fiber identifier to detect whether there is a signal transmitted by the light source device. If the transmitted signal can be detected, it means that the two people are operating the same optical fiber, and then the optical fiber identification is completed.

[0004] Patent application number CN201410814701.9 discloses a device for detecting optical fiber routing information, comprising a mechanical clamp assembly, a clamping information acquisition module and / or a drive device, and a communication module. The mechanical clamp assembly is used to bend the optical fiber; the clamping information acquisition module is used to collect the clamping pattern of the mechanical clamp assembly; the communication module is used to transmit information, the clamping information acquisition module is connected to the communication module, and the drive device is used to drive the mechanical clamp assembly. The utility model also discloses a system capable of detecting optical fiber routing information, including the device, and a method for detecting routing information using the system. The utility model utilizes a dedicated device to clamp an optical fiber, causing optical power variations. The clamping pattern of the dedicated device is recorded, and a receiving end whose power variation pattern is consistent with the variation in tension of the device clamping the optical fiber is matched. The physical geographic identifier of the receiving end of the tested optical fiber is thus matched, ultimately determining the physical routing information of the clamped optical fiber or the user connected to the port. However, this structure requires a large vibration drive structure and a long travel distance to generate optical power variations, which is not conducive to device miniaturization.

[0056] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0057] Example 1: Figures 1 to 13 As shown, a fiber optic identification device is mainly used to be fixed on an optical cable, change the optical power of the optical cable, and detect the optical power of the optical cable.

[0058] The base 1 is provided with a first fixed guide rail 2 for the optical cable, which is used to fix the first section of the optical cable. The base is also provided with an arc-shaped guide rail, which can be divided into multiple sections. The first guide rail 3, located at the upper portion of the base 1, is hollowed out by the base 1 and cooperates with the arc-shaped guide rail 5 at the rear of the rotating seat 4. The second guide rail 6, located at the lower portion of the base 1, is an arc-shaped groove formed by the main body of the base 1. The lower main body of the rotating seat 4 is provided with an extended arc-shaped guide rail 7, thereby rotatably setting the rotating part 4 on the base 1. Of course, a rotating shaft structure can also be provided between the rotating seat and the base at or near the center of the rotation, that is, the rotating seat 4 is rotatably set on the base 1 with the intersection between the first fixed guide rail 2 and the second fixed guide rail 18 of the optical cable as the center of the circle. The base 1 is provided with a magnet receiving groove, which is used to accommodate the magnet 8. A first fixing block accommodating groove 9 is provided on the base 1 at a position corresponding to the first optical cable fixing guide rail 2 .

[0059] A first fixing block 10 is disposed within the first fixing block receiving groove 9. The top of the first fixing block receiving groove 9 is shaped to mate with the first optical cable fixing rail 2 to secure the optical fiber. A first elastic member, such as a spring 11, is disposed at the bottom of the first fixing block 10. The spring 11 provides upward pressure on the first fixing block 10, pressing it toward the first optical cable fixing rail 2, thereby securing the first section of the optical cable to the first optical cable fixing rail 2.

[0060] Vertical guide posts 12 are provided on both sides of the bottom of the base 1. Springs 13 are installed on the guide posts 12. Steps 15 are provided on both sides of the sliding door 14, which contact the guide posts 12. The sliding door 14 abuts against the springs 13 via the steps 15, allowing the sliding door to rebound upward. An abutment platform 15 is provided on the outer surface of the first fixed block 10. The abutment platform 15 protrudes from the surface of the first fixed block 10, and an abutment groove 16 is provided on the inner side of the inner side of the sliding door 14. Because the spring 13 has less force at the top, to prevent the sliding door 14 from returning to its original position, a second magnet 17 is provided on the inner side of the sliding door 14, which corresponds to the magnet 8 on the base 1. The two magnets push the sliding door 14 back to the top to cover the first fixed guide rail 2 of the optical cable through attraction or repulsion.

[0061] like Figure 8 and Figure 9 As shown, a collision portion is formed between the abutment platform 15 and the abutment groove 16. When the sliding door 14 is in its natural position, the sliding door 14 is at the top, with a certain distance between the abutment platform 15 and the abutment groove 16. After the sliding door 14 slides down a short distance, the collision portion drives the first fixing block 10 downward. This arrangement ensures that the first fixing block 10 does not interfere with the sliding door 14 when squeezing and securing the optical cable within the first fixing guide rail 2.

[0062] The rotating base 4 is provided with a second optical cable fixing rail 18, which is used to fix the second section of the optical cable. The rotating base 4 is rotatably mounted on the base 1 and can be rotated to a position where the first and second sections of the optical cable are in a straight line, via the first and second optical cable fixing rails, or to a position where the first and second sections of the optical cable are at an angle, via the first and second optical cable fixing rails, with a bend between them.

[0063] A second fixing block 19 is provided on the rotating seat 4 . The second fixing block 19 provides elastic force through a second elastic member. The second elastic member can be a spring 20 . The second fixing block 19 fixes the second section of the optical cable to the second optical cable fixing rail 18 .

[0064] The second fixing block 19 is provided with a limit arm 21, the rotating base 4 is provided with a through slot 22, and the base 1 is provided with a limit step 23. The limit arm 21 passes through the through slot 22 and abuts against the limit step 23. The through slot 22 allows the second fixing block 19 to move to squeeze the optical cable on the second optical cable fixing rail 18, and to move to an open position to allow the optical cable to enter the second optical cable fixing rail 18.

[0065] like Figure 10 and Figure 11As shown, the limiting arm 21 and the limiting step 23 are configured such that, when the rotating seat 4 rotates to the point where the first section and the second section of the optical cable are in a straight line through the first and second fixing guide rails 2 and 18, the limiting arm 21 abuts against the limiting step 23, causing the second fixing guide rail 18 to be in an open state, allowing the optical cable to be loaded into the second fixing guide rail 18. When the rotating seat 4 rotates to the point where the first and second sections of the optical cable form an angle through the first and second fixing guide rails 2 and 18, forming a bend between the first and second sections of the optical cable, the limiting arm 21 disengages from the limiting step 23, causing the second fixing block 19 to squeeze the optical cable located on the second fixing guide rail 18.

[0066] That is, as the rotating seat 4 gradually moves toward the alignment of the first and second optical cable fixing rails 2 and 18, the limiting arm 21 first abuts against the limiting step 23. The rotating seat 4 then continues to rotate, compressing the spring and preventing the second fixing block 19 from moving forward. As the rotating seat 4 moves from the alignment of the first and second optical cable fixing rails 2 and 18 until the angle between them gradually increases, the limiting arm 21 disengages from the limiting step 23, causing the second fixing block 19 to press against the optical cable on the second optical cable fixing rail 18. This allows the rotating seat 4 to be positioned horizontally, making it easier to load the optical cable. After the rotating seat 4 is rotated, the second fixing block 19 compresses and secures the optical cable.

[0067] The inner edge of the rotating base 4 is provided with a toothed damping opening 24, and the base 1 is provided with damping teeth 25. The rotating base 4 has a manual toggle portion 26 extending to the outside of the base 1. In this way, when the rotating base 4 is rotated by toggling the manual toggle portion 26, the toothed damping opening 24 and the damping teeth 25 cooperate to enable the rotating base 4 to stop when the toggle stops.

[0068] The first and second fixed guide rails 2 and 18 are configured as U-shaped grooves with the notches facing outwards so that the optical cables can be pressed in from the outside. The sliding door 14 is used to close or open the first and second fixed guide rails 2 and 18 in a horizontal state.

[0069] The detector 27 is disposed between the first optical cable fixing rail 2 and the second optical cable fixing rail 18. The detector 27 is used to detect the optical power of the bent portion of the optical cable.

[0070] like Figure 12 As shown, a limit switch 28 is also provided on the rear surface of the base 1. When the rotating seat 4 rotates to a certain angle, the limit switch 28 is touched. After touching the limit switch 28, it is proved that the rotating seat 4 has rotated to a certain position. At this time, the detector 27 can be set to be powered on to perform optical power detection.

[0071] The indicator light 29 is electrically connected to the detector 27, and the detector 27 detects the optical power of the bend between the first section of the optical cable and the second section of the optical cable. When the rotating seat 4 is rotated to enable the detector 27 to detect the optical power of the bend, the indicator light 29 lights up to indicate that the optical power at the bend has been detected. At this time, the optical power change operation can be performed or the change in optical power can be waited for.

[0072] The receiving device of the optical fiber identification system primarily detects signals indicating changes in optical power using a detector 27. A circuit board 30 is located behind the base 1 and enclosed within the base 1 via a rear cover 31. The detector 27 is used to detect signals indicating changes in optical power. During use, ensure that the rotating base 4 is horizontal, so that the first and second fixed guide rails 2 and 18 of the optical cable are aligned. First, pull down the sliding door 14. As the sliding door 14 is pulled down, it contacts the first fixed block 10, which pulls down and releases the first fixed guide rail 2. At this point, since the rotating base 4 is in its initial position, the limiting arm 21 of the second fixed block 19 abuts the limiting step 23, causing the second fixed guide rail 18 to also open, allowing the optical cable to be installed. Then, release the sliding door 14, which naturally moves upward, causing the first fixed block 10, driven by the spring, to compress and secure the first section of the optical cable on the first fixed guide rail 2. At this time, the rotating seat 4 is rotated, and the limiting arm 21 of the second fixed block 19 gradually disengages from the limiting step 23, so that the second fixed block 19 in the compressed state gradually loosens until it completely squeezes the second section of the optical cable located in the second fixed guide rail 18 of the optical cable. Continue to rotate the rotating seat 4 until the indicator light 29 is observed to light up, which indicates that the angle of rotation can detect the light leaking from the optical cable. At this time, the optical power detection can be performed. If the detected optical power changes, it proves that the receiving device is the receiving device where the target optical cable is located. Due to the different specifications of existing optical cables and the different services in the optical cables, the wavelengths are different. Therefore, if you want to detect the optical power through the light leaked from the optical cable, you need to bend at the same angle. This device can be applied to different optical cable specifications and service types to ensure accuracy, and can be applied to the application scenario of large-scale routing detection.

[0073] The difference between the signal generating device and the signal receiving device of the optical fiber identification system is that it needs to vibrate the optical cable to make the optical power of the optical cable change periodically, so as to determine the port of the optical cable. Figure 13As shown, a vibration device is provided for this purpose, and the vibration device is arranged on the first fixed guide rail 2 of the optical cable or the second fixed guide rail 18 of the optical cable. The vibration device includes a vibration block 32, which is connected to a turntable via a movable connecting rod 33, and the turntable is further connected to a motor 34, thereby generating vibration, or the vibration block 32 is directly connected to a vibration motor. Due to the small structure of the overall device, the vibration block 32 occupies a large part of the position of the first fixed guide rail 2. For this reason, a first fixed block 35 is provided between the first fixed guide rail 2 of the optical cable and the second fixed guide rail 18 of the optical cable. The first fixed block 35 is used to fix the curved portion between the first section of the optical cable and the second section of the optical cable to the base 1. The way it is installed with optical fibers is similar to that of the receiving device. When the rotating seat rotates until the detector 27 detects optical power, that is, light leakage, it stops rotating. At this time, the vibration device vibrates the optical cable to generate optical power changes in the optical cable. The optical cable is rotated to a certain angle to detect the optical power and then vibrated. At this time, a smaller vibration amplitude can be used to generate a larger optical power change in the optical cable without high-frequency or large-amplitude vibration. The overall structure is small and the vibration amplitude is small, which avoids damage to the optical cable caused by excessive vibration amplitude.

[0074] Example 2:

[0075] An optical fiber identification device, such as Figures 14 to 21 As shown, the rotating seat 36 and base 37 of the optical fiber identification device are arranged around a detector 38, with a rotating portion 39 arranged around the rotating portion 39. The rotating portion 39 is configured to rotatably couple the rotating seat 36 and base 37 together through a hollow annular seat 40 and a corresponding nesting structure 41. The rotating seat 36 and base 37 have essentially the same functions; their names serve primarily to distinguish them. The hollow portion of the annular seat 40 is used to accommodate the detector 38. The rotating seat 36 and base 37 are rotatably coupled together through a locking block 42 and corresponding stopper extensions. The rotating structure of the rotating seat 36 is provided with a clearance notch 43, which ensures that the optical cable passes from the first fixed cable rail 44 through the rotating portion 39 and enters the second fixed cable rail 45. The size of the clearance notch 43 corresponds to the corresponding circumferential stopper structure that allows rotation. The stopper structure can be the outer shell 46 of the rotating portion 39 on the base 37 and a corresponding notch 47 on the rotating seat 36. When the end of the outer shell 46 abuts against the notch 47, the maximum rotation angle allowed for the rotating seat 36 and the base 37 is reached. At the same time, damping teeth are provided on the inner side of the outer shell 46, and the rotating seat 36 is also provided with damping teeth that cooperate with them. Through the cooperation of the two, the rotating seat 36 and the base 37 can stop at any angle allowed within the rotation range.

[0076] Abutment block 48 is positioned at the edge corresponding to detector 38. It is generally fan-shaped, with its apex generally oriented toward the center of detector 38. It is located at the angle between rotating base 36 and base 37. One straight side of abutment block 48 is substantially flush with the inner edge of second fixed rail 45 on the bending direction. When rotating base 36 is rotated to its maximum angle, the other side of abutment block 48 is substantially flush with the inner edge of first fixed rail 44 on the bending direction. Experimental results have repeatedly confirmed that when rotating base 36 is rotated to its maximum angle, the optimal position of abutment block 48 is when the other side of abutment block 48 slightly protrudes from the first fixed rail. This is because optical cables, especially those with obtuse bends, are not completely circular. The bend has a small initial curvature before becoming circular. This protruding portion conforms to the curved portion of the cable, ensuring accurate bending and minimizing interference from external vibrations. In this way, when the rotating seat and the base rotate relative to each other, the abutment block enables the optical cable to stably follow the angle between the first fixed guide rail and the second fixed guide rail of the optical cable to form a corresponding bend.

[0077] Furthermore, the outer ends of the first and second cable fixing rails 44 and 45 are provided with snap-on connectors 49, which accept cable extension sleeves 50 or gaskets 51. The cable extension sleeves 50 are designed to extend from both sides in bright sunlight to prevent light leakage from interfering with the detector 38. The cable extension sleeves 50 themselves also secure the optical cable. The gaskets 51, made of a soft material, are also used to secure the optical cable.

[0078] The first cover 52 and the second cover 53 are respectively arranged on the base 37 and the rotating seat 36 so as to be openable and closable via a hinge. The first cover 52 and the second cover 53 are rotatably arranged together via the cover rotating portion. The second cover 53 is provided with a shaft hole 54, and the first cover 52 is provided with a seat structure 55, and the two cooperate to form the cover rotating portion. The rotation axis of the cover rotating portion is coaxial with the rotation axis of the seat rotating portion. The first cover 52 and the second cover 53 cooperate with the rotating seat 36 and the base 37 to fix the optical cable located in the first fixed guide rail 44 and the second fixed guide rail 45 of the optical cable. The cover rotating portion is snapped onto the seat rotating portion to form an internal seal, thereby ensuring the accuracy of the detector 38. In addition, the length of the base 37 can be greater than the length of the rotating seat 36.

[0079] The structure of Example 2 is compact and easy to use by providing a rotating base 39 around the detector 38. The bottom of the rotating base 36 and the base 37 can be provided with a circuit board for the detector 38. The wiring outlet of the circuit board can be provided with an indicator light 56 ​​to indicate whether the detector 38 has detected light leakage from the optical cable.
