Description

Technical Field

[0001] The present invention relates to the technical field of wavelength division communication equipment, and specifically relates to a wavelength division multiplexing optical communication device. Background Technique

[0002] A wavelength division multiplexing optical communication device is an optical communication device based on wavelength division multiplexing (WDM) technology. It can simultaneously transmit multiple optical signals with different wavelengths in the same optical fiber, thereby significantly improving the transmission capacity and efficiency of the optical fiber.

[0003] The most representative device of the wavelength division multiplexing device is the wavelength division multiplexer. The wavelength division multiplexer synthesizes a series of optical signals carrying information but with different wavelengths into a beam and transmits it along a single optical fiber; at the receiving end, the optical signals with different wavelengths are separated by a certain method. This is the technology adopted by the wavelength division multiplexer. This technology can simultaneously transmit multiple signals on a single optical fiber, and each signal is transmitted by light of a specific wavelength, which is a wavelength channel.

[0004] As the technical solution recorded in the prior art: CN207689711U, a wavelength division multiplexer. The wavelength division multiplexer of this technical solution is generally similar to the devices on the existing market. The main technical problem it solves is also the heat dissipation problem during its application, thereby protecting and improving the use efficiency of the wavelength division multiplexer.

[0005] There are many wavelength division multiplexers similar to the above. Analyzing from the main structure, the main improvement is mainly aimed at its own heat dissipation effect, and there are almost no improvements and designs in other aspects. This also makes the defects and problems that have always existed in the wavelength division multiplexer not well solved. For example: when plugging in the circuit, the fixing method between the wavelength division multiplexer and the circuit is very single, mainly relying on the friction between the plug and the socket on the wavelength division multiplexer. After long-term use, especially for the socket structure of the wavelength division multiplexer, it is very easy to cause damage, and then the friction will not be sufficient to keep the circuit plugged and fixed when plugging in the circuit later, that is, the circuit plugging will have a problem of poor contact, resulting in signal reception and transmission failures.

[0006] Therefore, we propose a wavelength division multiplexing communication device to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a wavelength division multiplexing optical communication device to solve the problems raised in the above background technique.

[0008] To achieve the above purpose, the present invention provides the following technical solutions:

[0014] Preferably, the limiting piece is located in the inner cavity of the line plug interface, and the limiting piece is attached to the inner wall of the line plug interface.

[0015] Preferably, two ends of the tension spring respectively abut against the inner side wall of the strip groove and the side surface of the limiting slider, and the tension spring is in a compressed state in an initial state.

[0016] Preferably, the width and height of the limit sliding block are equal to the width and height of the inner side of the strip groove, and the toggle plate is attached to the outer side wall of the wavelength division multiplexer.

[0017] Preferably, the inner side wall of the outer frame is provided with a recessed structure, and the wavelength division multiplexer is buckled into the recessed structure of the outer frame and is locked and fixed by bolt fasteners.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The wavelength division multiplexing optical communication device changes the single friction fixation of the line plugging of the traditional wavelength division multiplexer into a variable clamping mode through the design and use of the line plug interface, the clamping sheet, the anti-slip rubber sheet, the tension spring and the limit slider, which not only makes the line plugging and unplugging more convenient, but also can well solve the problem of looseness and instability caused by long-term and multiple plugging and unplugging of the line connector, that is, the problem of poor contact of the line connector.

[0021] 2. The wavelength division multiplexing optical communication device, through the design and use of the line plug interface, the clamping piece, the anti-dropping rubber sheet, the tension spring and the limit slider, when the wavelength division multiplexer is in use, the plugged line connector is always in the direction of being pulled toward the wavelength division multiplexer, generating a movement trend, that is, when in use, the stability of the entire plug-in line can be ensured, and the problem of falling off will not easily occur.

[0022] 3. In the wavelength division multiplexing optical communication device, the hot air inside the wavelength division multiplexer flows out along the inclined heat dissipation holes and flows out to the external environment through the air circulation holes on the outer frame, and new cold air enters from the air circulation holes on the other side, so that heat exchange can be achieved more accurately and quickly. In addition, the inclined heat dissipation hole design can prevent pollutants such as dust from entering the interior of the device during heat exchange, thereby preventing the internal components from being affected.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: Please refer to Figures 1-5 , the present invention provides a technical solution: a wavelength division multiplexing optical communication device.

[0031] A wavelength division multiplexing optical communication device is an optical communication device based on wavelength division multiplexing technology. It can simultaneously transmit multiple optical signals with different wavelengths in the same optical fiber, thereby significantly improving the transmission capacity and efficiency of the optical fiber. The most representative device of the wavelength division multiplexing device is the wavelength division multiplexer. The wavelength division multiplexer combines a series of optical signals carrying information but with different wavelengths into a single beam and transmits it along a single optical fiber; at the receiving end, the optical signals with different wavelengths are separated by a certain method. The wavelength division multiplexer adopts this technology, which can simultaneously transmit multiple signals on a single optical fiber, and each signal is transmitted by light of a specific wavelength, which is a wavelength channel.

[0032] The wavelength division multiplexing optical communication device generally includes the following key components:

[0033] Multiplexer (MUX) and demultiplexer (DEMUX): used to combine or separate optical signals with different wavelengths.

[0034] Optical amplifier: used to compensate for the attenuation of optical signals during transmission to ensure signal strength.

[0035] Light source and optical detector: used to generate and receive optical signals respectively.

[0036] According to different wavelength intervals, the wavelength division multiplexing optical communication device is mainly divided into the following types:

[0037] Coarse wavelength division multiplexing (CWDM): uses a relatively wide wavelength interval (usually 20 nanometers or wider), suitable for lower-cost systems, but with fewer channels.

[0038] Dense wavelength division multiplexing (DWDM): uses a more dense wavelength interval (such as 100 GHz or smaller), can support more channels, and is suitable for high-capacity transmission.

[0039] Application scenarios:

[0040] The wavelength division multiplexing optical communication device is widely used in modern communication networks, including data centers, long-distance communications, high-speed networks, etc., and can effectively improve the transmission efficiency of existing optical fiber infrastructure.

[0041] When the wavelength division multiplexer is specifically used, there are some problems and defects in the line connection position as follows:

[0042] 1. Optical fiber connection problems:

[0043] The optical fiber is not inserted properly or is loose: This may cause attenuation or interruption of the optical signal, affecting the transmission quality.

[0044] The optical fiber is inserted incorrectly for reception / transmission: This may cause the signal to not be transmitted normally.

[0045] The optical fiber connector is contaminated or damaged: If the optical fiber connector is not clean or has physical damage, it will cause attenuation or interruption of the optical signal.

[0046] 2. Terminal deformation or damage:

[0047] Terminal deformation: The elastic structure of the female terminal is deformed or the male terminal is skewed, which may cause poor contact or virtual connection.

[0048] Terminal damage: Excessive plugging and unplugging or improper operation may cause the terminal to wear, loosen or have poor contact.

[0049] 3. Crimping problems:

[0050] The crimping height is incorrect: Too small or too large crimping height may cause poor contact between the cable and the terminal, affecting signal transmission.

[0051] The cable is inserted too deep or too shallow: This may cause a reduction in the metal-to-metal contact in the conductor crimping area, reducing the signal transmission efficiency.

[0052] The crimping tool is worn or there is foreign object interference: The worn crimping tool or the presence of foreign objects may cause uneven crimping or damage.

[0053] 4. Plug-in terminal design problems:

[0054] The mating clearance of the connector is too large: This may cause unstable connection or poor contact.

[0055] There is too much clearance between the terminal and the cable wire: This increases the contact resistance and affects the normal operation of the circuit.

[0056] 5. Other problems:

[0057] Excessive plugging and unplugging: Frequent plugging and unplugging may cause the terminal to wear or have poor contact.

[0058] The influence of thermal expansion and contraction: Temperature changes may cause the terminal and the cable wire to become loose or break.

[0059] Vibration or impact: This may cause the terminal to become loose or have poor contact.

[0060] Example 1:

[0061] The wavelength division multiplexing communication device mainly includes an outer frame 1 and a wavelength division multiplexer 2. Figure 2 As shown, the inner wall of the outer frame 1 is in a concave state, the wavelength division multiplexer 2 is buckled into the inner circle of the outer frame 1 and fixed by bolt fasteners, and line plug interfaces 3 are installed at equal distances on the back of the wavelength division multiplexer.

[0062] like Figure 2 As shown, strip grooves 4 are provided at upper and lower positions on both side walls of the line plug-in port 3 , and a limit rod 5 is installed through the inner cavity of the strip groove 4 .

[0063] like Figure 3 As shown, a limiting slider 6 is mounted on the outer ring of the limiting rod 5 located in the inner cavity part of the strip groove 4, a toggle plate 7 is fixedly mounted on one side of the limiting slider 6, a limiting plate 8 is mounted on the other side of the limiting slider 6, a clamping plate 9 is integrally fixedly connected to the end position of the limiting plate 8, and an anti-slip rubber sheet 10 is fixedly bonded to the side opposite to the clamping plate 9, and a tensioning spring 11 is mounted on the outer ring of the limiting rod 5.

[0064] The two ends of the tension spring 11 respectively abut against the side surface of the limiting slider 6 and the inner wall of the strip groove 4 .

[0065] Among them, Figure 3 and Figure 4 As shown, a locking piece 12 is integrally fixedly connected to the end of the toggle plate 7 , and arc-shaped protrusions 13 are integrally provided on both sides of the back of the wavelength division multiplexer 2 .

[0066] Among them, Figure 4 As shown, a locking protrusion 14 is fixedly welded on one side of the locking sheet 12 close to the arc-shaped protrusion 13 , and a locking groove matched with the locking protrusion 14 is provided on the arc-shaped surface of the arc-shaped protrusion 13 .

[0067] The clamping piece 9 and the locking piece 12 are both elastic thin sheet structures.

[0068] In this embodiment, when the wavelength division multiplexing communication device of the present technical solution is used, it is mainly aimed at when the line connector is plugged in. In the initial state, the locking protrusion 14 is clamped in the locking groove, the tension spring 11 is in a compressed state, and the clamping sheet 9 and the anti-slip rubber sheet 10 are as shown in FIG. Figure 2 In the state shown, the clamping piece 9 is in a state of expanding outwards, and the limiting piece 8 is tightly fitted on the inner wall of the line plug port 3 .

[0069] When plugging in the circuit connector, both sides of the circuit connector are directly attached to the limiting piece 8 and continuously inserted into the circuit socket 3. After the plugging is completed, manually pull the locking pieces 21 to both sides respectively, so that the locking protrusions 14 on the locking piece 12 are separated from the locking grooves. Then, the tension spring 11 loses its binding force, and relying on the reaction force of the inner wall of the strip groove 5, continuously pushes the limiting slider 6 to move along the axial direction of the limiting rod 5. When the limiting slider 6 moves, it drives the limiting piece 8 to move synchronously, and the limiting piece 8 drives the clamping piece 9 at its end position to move synchronously. The clamping piece 9 and the anti-disengagement rubber piece 10 on it will gradually be received into the circuit socket 3. The clamping piece 9 is gradually pressed by the inner wall of the circuit socket 3 and approaches the outer wall of the plug connector until the anti-disengagement rubber piece 10 is pressed against the outer wall of the circuit library plug.

[0070] Subsequently, during use, since the tension spring 11 is always in a state of pressing the limiting slider 13, and the clamping piece 9 and the anti-disengagement rubber piece 10 always press and hold the outer wall of the plug connector.

[0071] Therefore, firstly, through the design and use of the circuit socket 3, the clamping piece 9, the anti-disengagement rubber piece 10, the tension spring 11 and the limiting slider 6, the single frictional fixation of the circuit plug-in of the traditional wavelength division multiplexer is changed to a variable clamping method. Not only is the circuit plugging and unplugging more convenient, but also the problem of looseness and instability caused by long-term and multiple plugging and unplugging of the circuit connector, that is, the problem of poor contact of the circuit connector, can be well solved.

[0072] Secondly, through the design and use of the circuit socket 3, the clamping piece 9, the anti-disengagement rubber piece 10, the tension spring 11 and the limiting slider 6, when the wavelength division multiplexer 2 is in use, the plugged circuit connector is always pulled in the direction of the wavelength division multiplexer 2, generating a movement trend. That is, during use, the stability of the entire plugged circuit can be ensured and it is not easy to fall off.

[0073] Embodiment 2:

[0074] As Figure 1 and Figure 5 shown, air circulation openings 15 for the heat dissipation of the entire device are provided on both side walls of the outer frame 1.

[0075] As Figure 5 shown, arc-shaped recessed areas 16 are provided on both side surfaces of the housing of the wavelength division multiplexer 2, and a plurality of heat dissipation holes 17 are provided on one side of the inner wall of the arc-shaped recessed area 16.

[0076] Among them, heat dissipation fans are installed on both sides of the inner cavity of the wavelength division multiplexer 2 and at the rear position of the heat dissipation holes 17.

[0077] Among them, the heat dissipation hole 17 is an inclined hole, and the air outlet position of the heat dissipation hole 17 faces the air circulation port 15 on the left side.

[0078] In this embodiment, when using the communication device of this technical solution, a large amount of heat will be generated by various internal components during the operation of the entire wavelength division multiplexer 2. During its operation, the internal cooling fan will work synchronously to discharge the internal hot air outwards. Affected by the cooling fan, the hot air flows out from the heat dissipation hole 17 to the outside. The design of the inclined heat dissipation hole 17 makes the hot air flow only in the same direction. When the hot air flows, new cold air needs to enter between the outer frame 1 and the outer wall of the wavelength division multiplexer 2, that is, the cold air flows in from the air circulation port 15 on the right side for heat exchange. Moreover, the entry of cold air will flow along with the hot air, thus accelerating the speed of the entire air circulation. And because the heat dissipation hole 17 is designed at an inclined angle, therefore, dust and other pollutants carried by the cold air will not easily enter the wavelength division multiplexer 2.

[0079] When using this technical solution, the hot air inside the wavelength division multiplexer 2 flows out along the inclined heat dissipation hole 17 and flows out to the external environment through the air circulation port 15 on the outer frame 1, and new cold air enters from the air circulation port 15 on the other side, realizing heat exchange more accurately and quickly. Moreover, the design of the inclined heat dissipation hole 17 can prevent dust and other pollutants from entering the device during heat exchange, thus avoiding the problem that the internal components are affected.

[0080] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "install", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0081] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
