Description

Technical Field

[0001] The present invention relates to the field of photoelectric signal transmission, and in particular to a photoelectric hybrid module and an assembly method thereof. Background Art

[0002] As communication technology continues to innovate, optoelectronic hybrid modules, as key components that integrate optical communication and electrical transmission functions, play a vital role in many fields. With the large-scale advancement of 5G network construction, the exponential growth of data volume in data centers, and the continuous expansion of IoT application scenarios, the demand for high-speed, stable communication connections with power supply capabilities is becoming increasingly urgent, and optoelectronic hybrid modules have come into being.

[0003] Early communication transmission mainly relied on pure copper cables. Although they performed well in short-distance electrical signal transmission, they faced problems such as severe signal attenuation and limited bandwidth in long-distance transmission. The emergence of fiber-optic communication technology effectively solved the problem of long-distance, high-bandwidth data transmission. However, single optical fiber cannot provide power support for equipment. To meet the needs of integrated communication and power supply, optoelectronic hybrid modules were developed and gradually applied.

[0004] At present, optoelectronic hybrid modules have been widely used in 5G base station construction to realize communication signal transmission and power supply of base station equipment; within data centers, they are used for high-speed connections between servers and switches to improve data interaction efficiency; in the field of intelligent transportation, they ensure the stable operation of traffic monitoring equipment and vehicle-road cooperative systems. However, existing optoelectronic hybrid modules have exposed many drawbacks in actual applications.

[0005] 1. High coupling tolerance cost

[0006] When connecting traditional AOC optical modules, the optical fiber needs to be connected to the optical engine in the optoelectronic hybrid module through a fiber winding process, resulting in a coupling yield of only 65% ​​to 75% and high single-port coupling costs. In addition, due to the long length of the optical fiber (usually ≥100mm) and its easy bending in the winding direction (minimum bending radius 25mm), high-precision alignment equipment is required, which increases equipment investment and operational difficulty.

[0007] 2. Insufficient optical connection reliability

[0008] Traditional coupling methods rely on static alignment and cannot compensate for optical axis deviation caused by environmental factors such as thermal expansion and mechanical vibration. This leads to increased coupling loss during long-term use and affects system stability.

[0009] 3. High maintenance costs

[0010] Existing optical engines and hybrid cables use an integrated design. When the optical chip or other auxiliary components in the optical engine fail, the module and hybrid cable must be replaced as a whole. Maintenance costs account for more than 30% of the life cycle cost. The replacement process also requires re-calibration of optical power (taking ≥2 hours), affecting system availability.

[0011] Therefore, there is a need for an optoelectronic hybrid module that can reduce coupling tolerance costs, improve optical connection reliability, and reduce maintenance costs, so as to promote the further development of optoelectronic hybrid module technology and meet the growing communication needs. Summary of the Invention

Such a configuration improves the coupling stability of the separate coupling component and improves the reliability of the optical connection.

[0017] In a preferred embodiment of the technical solution of the present invention, a fixed key installation groove is provided on the limit box base, and the metal fixed key on the optoelectronic hybrid cable is provided in the fixed key installation groove. Such a setting ensures the stability of the optoelectronic hybrid cable in the limit box and further improves the stability of the coupling.

[0018] In the preferred embodiment of the technical solution of the present invention, a cable channel is provided between the connection card and the limit box base, and the cables in the optoelectronic hybrid cable pass through the cable channel and are connected to the PCB board on the light engine. The setting of the cable channel realizes the effective separation of the optical signal and electrical signal transmission paths, ensures the stable interconnection between the separate coupling components, and the tight fixation of the cable and the PCB, and also provides more reliable physical protection for the optical fiber and cable, effectively reducing the electromagnetic interference to the signal transmission.

[0019] In a preferred embodiment of the technical solution of the present invention, the dynamic compensation mechanism includes a spring and a spring mounting sleeve, the spring mounting sleeve is connected to the separate coupling component, the spring is sleeved outside the spring mounting sleeve, and the optical fiber in the optoelectronic hybrid cable passes through the spring mounting sleeve and is connected to the separate coupling component. The setting of the dynamic compensation mechanism facilitates dynamic compensation of the coupling of the optical connection through the spring, compensates for the optical axis deviation caused by environmental factors such as thermal expansion and mechanical vibration, and improves stability.

[0020] In a preferred embodiment of the technical solution of the present invention, the detachable coupling assembly includes an MT connector and a snap-on terminal block. The optical fiber in the optoelectronic hybrid cable is detachably connected to the light engine through the MT connector, and the cable in the optoelectronic hybrid cable is connected to the PCB board on the light engine through the snap-on terminal block. This arrangement facilitates rapid disassembly and assembly of the optoelectronic hybrid cable and the light engine, improves maintenance speed, and reduces maintenance costs.

[0021] In order to solve the above-mentioned problems of time-consuming and high-cost maintenance, a method for assembling a photoelectric hybrid module is proposed; the method is implemented by the following technical solution: a method for assembling a photoelectric hybrid module, characterized by comprising the following steps:

[0022] S1. Place the MT ferrule and dynamic compensation mechanism connected to the optoelectronic hybrid cable into the base of the limit box;

[0023] S2. Place the metal fixing key on the optoelectronic hybrid cable into the fixing key installation slot and lead the cable out from the cable channel in the base of the limit box;

[0024] S3. Plug the two MT ferrules together to complete the MT docking of the optical engine. Then use the snap-on terminal blocks to connect the cable to the PCB, and then close the upper cover of the limit box.

When the dynamic compensation mechanism is placed in the connection card, the spring in the dynamic compensation mechanism rests on the spring limit surface. This arrangement ensures the stability of the optical connection and simultaneously ensures that the dynamic compensation mechanism can continuously provide pressure to the MT connector, thereby ensuring the reliability of the optical connection.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The use of separate coupling components reduces coupling tolerance costs and avoids the problem of low coupling efficiency and increased coupling difficulty caused by the long length of optical fiber and its tendency to bend in the winding direction;

[0030] The entire device is easy to assemble and disassemble. When some parts of the device fail, they can be easily replaced without large-scale disassembly and debugging of the entire system module, which significantly reduces maintenance costs and improves the overall reliability and economy of the system.

DETAILED DESCRIPTION

[0045] The following is a combination of the embodiments of the present invention Figures 1-13 , the technical solutions in the embodiments of the present invention are described in detail.

[0046] like Figure 1 、 Figure 2 、 Figure 5 and Figure 13 As shown, an optoelectronic hybrid module includes an upper cover 1, a base 2, a separate coupling component 3, a coupling limit component 4, a dynamic compensation mechanism 5, a light engine 6, an unlocking component 7 and an optoelectronic hybrid cable 8.

[0047] The upper cover 1 and the base 2 are detachably connected by screws. After the upper cover 1 and the base 2 are connected, space is left in the middle of the upper cover 1 and the base 2 for installing the separable coupling component 3, the coupling limit component 4 and the dynamic compensation mechanism 5. The light engine 6 is installed in the space formed by the upper cover 1 and the base 2, and the light engine 6 is fixed on the base 2.

[0048] The optoelectronic hybrid cable 8 is quickly connected to the optical engine 6 through the separate coupling component 3, which enables rapid disassembly of the optical engine 6 and facilitates replacement of optical chips or other accessories in the optical engine when they fail, avoiding replacement of the entire module.

[0049] The coupling limit assembly 4 is arranged in the base 2, and the detachable coupling assembly 3 can be detachably connected in the coupling limit assembly 4. The setting of the coupling limit assembly 4 improves the coupling stability of the detachable coupling assembly 3 and prevents the coupling from being unstable due to external force or vibration.

[0050] The dynamic compensation mechanism 5 is arranged in the coupling limit assembly 4. The dynamic compensation mechanism 5 is connected to the coupling limit assembly 4 and the separate coupling assembly 3. The dynamic compensation mechanism 5 can continuously apply pressure to the separate coupling assembly 3 to compensate for the optical axis deviation caused by environmental factors such as thermal expansion and mechanical vibration, thereby improving the stability of the optical connection.

[0051] The unlocking component 7 is provided on the base 2 , and the connection between the module and the switch interface or the server interface can be quickly released by the unlocking component 7 , making it convenient to remove the optoelectronic hybrid module.

[0052] like Figure 1 、 Figure 3 and Figure 4 As shown, the upper cover 1 and the base 2 are rectangular boxes made of plastic. The upper cover 1 can be connected to the base 2 by screws. After the upper cover 1 and the base 2 are connected, one end can be plugged into the switch interface or the server interface.

[0053] The base 2 is rectangular as a whole, and a groove is formed on the surface of the base 2. At the same time, corresponding steps and grooves for limiting are opened in the groove to facilitate the placement of the light engine 6 and the coupling limit assembly 4 in the base 2. Regarding the fixation of the light engine 6 on the base 2, this embodiment preferably opens a groove on the base 2 with the same contour as the light engine 6. The light engine 6 can be placed in the groove, and after the upper cover 1 is closed, the upper cover 1 can press the light engine 6 to ensure the stability of the light engine 6 in the base 2. This fixing method is well known to those skilled in the art and will not be described in detail here.

[0054] After the upper cover 1 closes the base 2, in order to improve the stability of the coupling limit assembly 4 in the base 2, two rectangular bosses are protruded on the fitting surface of the upper cover 1 and the base 2, and the bosses are named upper limit bosses 11. At the same time, a rectangular boss is also protruded on the corresponding surface of the base 2, and the bosses are named lower limit bosses 21. After the coupling limit assembly 4 is placed in the base 2, the upper cover 1 and the base 2 cooperate with the coupling limit assembly 4 through the upper limit boss 11 and the lower limit boss 21 to fix the position of the coupling limit assembly 4, thereby ensuring the stability of the coupling of the separate coupling assembly 3 arranged in the coupling limit assembly 4.

[0055] like Figure 2 、 Figure 5 and Figure 6 As shown, the split coupling assembly 3 includes an MT connector 31 and a snap-on terminal block 32. The MT connector 31 is mainly used to connect the optical fiber 83 in the optoelectronic hybrid cable 8 to the optical engine 6, and the snap-on terminal block 32 is mainly used to connect the cable 82 in the optoelectronic hybrid cable 8 to the optical engine 6.

[0056] The MT connector 31 is an existing MT ferrule-type optical fiber connector device that can be purchased and used directly. The MT connector 31 includes two MT ferrules 33 that can be plugged into each other. One MT ferrule 33 is connected to the optical fiber 83 in the optoelectronic hybrid cable 8, and the other MT ferrule 33 is connected to the optical engine 6 via an optical fiber. The two MT ferrules 33 are detachable and pluggable to achieve an optical connection.

[0057] The snap-on terminal block 32 is an existing snap-on power supply terminal block that can be directly used with existing devices. Regarding the method of connecting the light engine 6 and the cable 82 in the optoelectronic hybrid cable 8 through the snap-on terminal block 32, the male connector in the snap-on terminal block 32 is soldered to the cable connection position corresponding to the PCB board 61 in the light engine 6, and the female connector in the snap-on terminal block 32 is connected to the cable 82 in the optoelectronic hybrid cable 8. Through the cooperation of the male and female connectors in the snap-on terminal block 32, the connection between the cable 82 in the optoelectronic hybrid cable 8 and the PCB board 61 in the light engine 6 is realized, which is convenient to use.

[0058] like Figure 2 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, in order to improve the coupling stability of the separate coupling component 3, a coupling limit component 4 is provided in the base 2. The coupling limit component 4 includes a limit box 41. The separate coupling component 3 can be detachably installed in the limit box 41. The coupling limit component 4 can limit the MT connector 31 in the separate coupling component 3 to ensure the stability of the coupling.

[0059] The limiting box 41 is a rectangular box made of plastic. One end of the limiting box 41 is open. The MT connector 31 placed in the limiting box 41 passes through the opening and is connected to the light engine 6 .

[0060] The limit box 41 includes a limit box upper cover 42 and a limit box base 43, and the limit box upper cover 42 and the limit box base 43 are connected by a snap. In order to improve the stability of the limit box 41 in the base 2, two rectangular grooves are concavely provided on the surfaces of the limit box upper cover 42 and the limit box base 43, and these grooves are named limit grooves 44. The limit grooves 44 can cooperate with the upper limit boss 11 in the upper cover 1 and the lower limit boss 21 on the base 2 to achieve fixation, thereby improving the stability of the limit box 41 in the base 2. When the upper cover 1 and the base 2 are connected, the limit box 41 can be stably fixed between the two.

[0061] In order to facilitate the insertion of the optoelectronic hybrid cable 8 into the limit box 41, a circular through hole is opened at one end of the limit box 41, and this through hole is named as the hybrid cable installation hole 46. The end of the optoelectronic hybrid cable 8 connected to the MT connector 31 passes through the hybrid cable installation hole 46 and is inserted into the limit box 41.

[0062] In order to facilitate the connection between the limit box cover 42 and the limit box base 43 to form the limit box 41, a clip with an "L"-shaped cross section is protruded on the contact surface of the limit box base 43 and the limit box cover 42. This clip is named a limit clip 414. The limit clips 414 are set at both ends and left and right sides of the limit box base 43. At the same time, a limit opening 413 that can cooperate with the limit clip 414 is opened on the limit box cover 42. The limit box cover 42 and the limit box base 43 cooperate with each other through the limit clip 414 and the limit opening 413 to form the limit box 41.

[0063] In order to facilitate the restriction of the MT connector 31, a connection card 47 is protruded outward on the bottom surface of the limit box base 43. The connection card 47 is two parallel rectangular strips. In order to avoid electromagnetic interference, a gap is left between the connection card 47 and the side wall of the limit box base 43. This gap is named cable channel 412. The cable 82 in the optoelectronic hybrid cable 8 passes through the cable channel 412 and is connected to the PCB board 61.

[0064] A groove is formed in the middle of two opposite sides of the connection card 47. The groove is named as the MT ferrule limiting groove. The end surface of the MT ferrule limiting groove is named as the MT limiting surface 410. The end of the MT ferrule 33 connected to the dynamic compensation mechanism 5 can abut against the MT limiting surface 410. Figure 10 shown.

[0065] A rectangular boss is protruded from two opposite sides of the connection card 47 near the hybrid cable installation hole 46. This boss is named the dynamic compensation mechanism limit platform, and the end surface of the dynamic compensation mechanism limit platform is named the spring limit surface 49. The end of the spring 51 in the dynamic compensation mechanism 5 rests on this spring limit surface 49. Figure 10 shown.

[0066] In order to further improve the stability of the fixation of the MT connector 31, two "L"-shaped bayonet holes are integrally fixed at the end of the connection card 47 away from the hybrid cable mounting hole 46. These bayonet holes are named MT limit bayonet holes 411. The two MT limit bayonet holes 411 are distributed opposite each other. The end of the MT ferrule 33 connected to the optical engine 6 in the MT connector 31 is abutted against these bayonet holes to achieve position limiting.

[0067] To ensure the compensation effect of the dynamic compensation mechanism 5, when the two MT ferrules 33 are plugged in and mated, the end of the MT ferrule 33 connected to the optical engine 6 abuts against the MT limit bayonet 411, while the MT ferrule 33 connected to the optoelectronic hybrid cable 8 is a certain distance away from the MT limit surface 410. The spring 51 applies force upward to the MT ferrule 33, causing it to move toward the MT limit surface 410, achieving dynamic compensation and ensuring the stability of the optical connection.

[0068] The optoelectronic hybrid cable 8 is inserted into the limit box 41 through the hybrid cable installation hole 46. In order to prevent the MT connector 31 from moving in the limit box 41 due to pulling the optoelectronic hybrid cable 8, thereby affecting the coupling effect, a metal fixing key 81 is integrally fixed to the optoelectronic hybrid cable 8. The metal fixing key 81 is annular in shape and has a threading hole in the middle of the metal fixing key 81. The optoelectronic hybrid cable 8 passes through the metal fixing key 81 through the threading hole, and the optoelectronic hybrid cable 8 is fixedly connected after passing through the metal fixing key 81.

[0069] In order to fix the metal fixing key 81, a groove that cooperates with the metal fixing key 81 is concave in the end of the limit box base 43 near the hybrid cable mounting hole 46, and this groove is named the fixing key mounting groove 48. At the same time, a groove is also formed at the corresponding position of the limit box upper cover 42. The metal fixing key 81 is placed in the fixing key mounting groove 48. After the limit box upper cover 42 and the limit box base 43 are closed, the optoelectronic hybrid cable 8 is stably fixed in the limit box 41 to prevent the MT connector 31 from moving in the limit box 41 due to pulling the optoelectronic hybrid cable 8, thereby affecting the coupling effect.

[0070] like Figure 5 、 Figure 6 、 Figure 8 and Figure 10 As shown, in order to compensate for the optical axis deviation caused by environmental factors such as thermal expansion and mechanical vibration and ensure the coupling stability of the MT connector 31, a dynamic compensation mechanism 5 is further provided in the limit box 41. The dynamic compensation mechanism 5 is connected to the MT ferrule 33 in the MT connector 31. The dynamic compensation mechanism 5 can continuously apply pressure to the MT ferrule 33 to ensure the coupling stability of the MT connector 31.

[0071] The dynamic compensation mechanism 5 includes a spring mounting sleeve 52 and a spring 51. The spring mounting sleeve 52 is a rectangular tube made of plastic. One end of the spring mounting sleeve 52 is fixed to the end of the MT ferrule 33 away from the plug interface by glue. The optical fiber in the optoelectronic hybrid cable 8 passes through the spring mounting sleeve 52 and is connected to the MT ferrule 33. A spring 51 is sheathed on the outside of the spring mounting sleeve 52. In this embodiment, this spring is preferably an existing rectangular spring. One end of the spring 51 contacts the end face of the MT ferrule 33, and the other end rests on the spring limit surface 49. When the spring 51 is installed, the spring 51 is in a compressed state.

[0072] The spring mounting sleeve 52 can prevent the spring 51 from contacting the optical fiber 83, thereby ensuring the stability of optical signal transmission. During production, the spring mounting sleeve 52 and the spring 51 are installed at the end of the optoelectronic hybrid cable 8 and cannot be removed. The MT ferrule 33 is installed after the spring mounting sleeve 52 and the spring 51 are installed.

[0073] like Figure 1 、 Figure 11 and Figure 12 As shown, after the end of the optoelectronic hybrid module is inserted into the switch interface or the server interface, an unlocking component 7 is further provided on the base 2 to facilitate the removal of the optoelectronic hybrid module.

[0074] The unlocking assembly 7 includes an unlocking handle 71, a locking limit hook 72 and an unlocking pull tab 73. The locking limit hook 72 can cooperate with the corresponding limit port in the switch interface or the server interface to fix the insertion of the optoelectronic hybrid module to prevent the optoelectronic hybrid module from accidentally falling off. The existing switch interface and server interface are both provided with a limit port that can cooperate with the locking limit hook 72, which is used here.

[0075] The locking limit hook 72 is an "L"-shaped metal sheet, with a hinge hole provided in the middle of the locking limit hook 72. A circular hinge platform 22 is correspondingly protruded on the side wall of the base 2. The hinge platform 22 can cooperate with the hinge hole, and the locking limit hook 72 rotates along the hinge platform 22. A triangular protrusion protrudes from one end of the locking limit hook 72. Through this protrusion, the locking limit hook 72 can cooperate with the corresponding limit port in the switch interface or server interface to achieve limitation.

[0076] There are two locking and limiting hooks 72 , which are hinged to the base 2 respectively, and the two locking and limiting hooks 72 are distributed in parallel on the base 2 .

[0077] In order to keep the locking limit hook 72 in the limited state, a limit spring 74 is fixed to the other end of the locking limit hook 72. One end of the limit spring 74 is in contact with the locking limit hook 72, and the other end is against the surface of the upper cover 1 after the upper cover 1 and the base 2 are connected. The pressure of the limit spring 74 ensures that the locking limit hook 72 and the corresponding limit port in the switch interface or server interface are always in a matched state.

[0078] The main function of the unlocking handle 71 and the unlocking tab 73 is to release the lock limit hook 72 from the corresponding limit opening in the switch interface or server interface when needed, thereby facilitating the removal of the optoelectronic hybrid module.

[0079] When the locking cam 72 is in the unlocking state, the locking cam 72 is in the unlocking state, and ...

[0080] like Figure 4 and Figure 12As shown, regarding the fixation of the unlocking pull tab 73 in the base 2, a slot is provided on the side wall of the base 2, and the unlocking pull tab 73 can be inserted into the slot. A rectangular guide groove 23 is recessed in the slot, and a rectangular guide slide 77 is also bent on the unlocking pull tab 73. The guide slide 77 can slide in the guide groove 23, and the sliding stroke is the stroke required to release the lock limit hook 72 from the corresponding limit port in the switch interface or server interface, and the guide groove 23 can limit the guide slide 77 to prevent the unlocking pull tab 73 from falling off the base 2.

[0081] A method for assembling a photoelectric hybrid module includes the following steps:

[0082] S1. Place the MT ferrule 33 and the dynamic compensation mechanism 5 connected to the optoelectronic hybrid cable 8 into the limit box base 43;

[0083] During this process, the MT ferrule 33 contacts the MT limiting surface 410 , and the spring 51 contacts the spring limiting surface 49 ;

[0084] S2. Place the metal fixing key 81 on the optoelectronic hybrid cable 8 in the fixing key installation groove 48 and lead the cable 82 out from the cable channel 412 in the limit box base 43;

[0085] S3. Plug the two MT ferrules 33 together to complete the MT connection of the optical engine 6. Then, use the snap-on terminal block 32 to connect the cable 82 to the PCB 61, and then cover the upper cover 42 of the limit box.

[0086] During this process, the end of the MT ferrule 33 connected to the optical engine 6 is stuck in the MT limit stopper 411;

[0087] S4. Place the limit box 41 and the light engine 6 into the base 2, cover the upper cover 1, and tighten the screws to complete the assembly of the optoelectronic hybrid module.

[0088] During this process, the limiting groove 44 on the limiting box 41 cooperates with the upper limiting boss 11 on the upper cover 1 and the lower limiting boss 21 on the base 2 respectively.

[0089] If the optical chip or other components in the optical engine 6 are damaged and need to be replaced, the following steps are included:

[0090] SS1. Remove the screws on the upper cover 1, open the upper cover 1, release the connection between the upper cover 1 and the base 2, and take out the limit box 41;

[0091] SS2. Use a screwdriver to press the limit card 414 on the limit box base 43 to release the connection between the limit card 414 and the limit opening 413 (this process is a common method for releasing the connection and belongs to the prior art). Then remove the limit box cover 42 to open the limit box 41.

[0092] SS3. Disconnect the two MT ferrules 33 and the snap-on terminal block 32 and remove the light engine 6.

[0093] SS4. Replace the optical engine 6 and connect the two MT ferrules 33 to complete the MT connection of the optical engine 6. Then use the snap-on terminal block 32 to connect the cable 82 to the PCB 61 and close the upper cover 42 of the limit box.

[0094] During this process, the end of the MT ferrule 33 connected to the optical engine 6 is stuck in the MT limit stopper 411;

[0095] SS5. Place the limit box 41 and the light engine 6 into the base 2, close the upper cover 1, and tighten the screws to complete the replacement of the light engine 6.

[0096] During this process, the limiting groove 44 on the limiting box 41 cooperates with the upper limiting boss 11 on the upper cover 1 and the lower limiting boss 21 on the base 2 respectively.

[0097] Advantages of this embodiment:

[0098] The optical fiber 83 of the optoelectronic hybrid cable 8 and the optical engine 6 adopt a separate modular design. Dynamic alignment of the optical fiber 83 and the optical engine 6 is achieved through the separate coupling component 3 and the dynamic compensation mechanism 5. This ensures a tight fit between the two ends of the separate coupling component 3, improving the stability of the optical connection. During implementation, the optical fiber 83 is led out from the middle of the optoelectronic hybrid cable 8 and precisely adapted to the optical engine through the MT connector 31. The cable 82 is led out through the cable channel 412, achieving effective separation of the optical and electrical signal transmission paths, ensuring the stability of the optical connection, and the tight fixation of the cable 82 to the PCB board 61.

[0099] The use of the separate coupling component 3 reduces the coupling tolerance cost and avoids the problem of low coupling efficiency and increased coupling difficulty caused by the long length of the optical fiber and its easy bending in the fiber winding direction;

[0100] The entire device is easy to assemble and disassemble. When some parts of the device fail, they can be easily replaced without large-scale disassembly and debugging of the entire system module, which significantly reduces maintenance costs and improves the overall reliability and economy of the system.

[0101] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
