Background
Submarine cables (undersea cables) are cables laid on the seabed, and optical fibers are wrapped in the undersea cables for transmitting optical signals on the seabed. Because the submarine communication distance is long, a large number of submarine cables are generally required to be sequentially butted together to form an optical signal transmission path with a sufficient length, and a connection structure for butting two adjacent submarine cables together is a submarine cable joint, taking the submarine cable joint shown in fig. 1 as an example, two submarine cables 40 which need to be butted enter the joint body 30 through the first connector 10 and the second connector 20 respectively, and are butted in the joint body 30.
The optical power of the optical signal is attenuated during transmission, the longer the transmission distance is, the lower the attenuation degree of the optical power is, and if the transmission distance is too long and the optical power of the optical signal is low, the optical signal is difficult to complete transmission. Optical signal transmission through submarine cables is usually long-distance signal transmission, and in order to complete the transmission of optical signals, the optical signals need to have high optical power. Generally, Optical components such as an Optical Equalizer (OEQ), a Remote Optical Amplifier (ROPA), etc. may be used to increase the output Optical power of the Optical signal, so as to increase the transmission distance of the Optical signal, thereby completing the transmission of the Optical signal in the submarine cable.
Since the submarine cable is laid on the seabed, the above-mentioned photovoltaic modules are also required to be used in the seabed environment, and in order to resist the erosion of seawater, the photovoltaic modules are required to be packaged. Taking the submarine cable joint shown in fig. 1 as an example, the joint body 30 has a cavity inside, and some photoelectric devices 50 can be built in, and since the submarine cable joint itself has certain insulation and sealing properties, and can protect the internal photoelectric devices 50, the submarine cable joint shown in fig. 1 can be used to package the photoelectric devices 50. However, the original function of the submarine cable joint is to realize the butt joint between the submarine cables, so that the requirement on the sealing performance of the submarine cable joint is relatively low, the sealing performance of the seams among all the parts on the submarine cable joint is poor, the seawater is difficult to be prevented from entering the submarine cable joint, and the normal operation of the photoelectric device inside the submarine cable joint is difficult to be ensured.

Thus, a cavity structure with certain pressure bearing and bearing capacity can be formed by the assembly of the first end face 131, the second end face 132, the first side wall 133, the second side wall 134, the first screw 135 and the second screw 136, and the optoelectronic device 137 is arranged in the cavity structure to obtain the optoelectronic device 13, wherein the cavity structure can protect the optoelectronic device 137 while loading the optoelectronic device 137.
The first sidewall 133 and the second sidewall 134 may have a curved inner wall structure, so that the cavity structure has a larger space for accommodating more optoelectronic devices 137 under the condition of the same outer volume. The shape and size of the radial cross section of the first end face 131 and the second end face 132 are consistent with the shape and size of the radial cross section of the cavity structure formed by the first side wall 133 and the second side wall 134, so as to ensure that the first side wall 133 can be assembled with the first end face 131, ensure that the second side wall 134 can be assembled with the second end face 132, and simultaneously prevent the first side wall 133 and the second side wall 134 from radially extending beyond the cavity structure after being assembled on the first end face 131 and the second end face 132, so as to avoid additional enlargement of the overall volume after assembly.
Furthermore, in some embodiments, in order to better fix and protect the optoelectronic device 137, a device box (not shown in the drawings) may be disposed in the cavity structure formed as described above, and the optoelectronic device 137 may be packaged in the device box, and an interface is opened on the device box, through which the internal optoelectronic device 137 may be electrically connected with an external device (for example, a submarine fiber, etc.).

When assembling, the photovoltaic device 137 is first fixed to the first sidewall 133 and/or the second sidewall 134, then the first sidewall 133 is disposed opposite to the inner wall of the second sidewall 134, finally the first sidewall 133 is fixed to the first end face 131 by the first screw 135, and the second sidewall 134 is fixed to the second end face 132 by the second screw 136, so as to obtain the photovoltaic module 13.
The pressure-bearing inner cylinder 14 is a hollow structure with a cavity, the photoelectric component 13 is arranged in the cavity of the pressure-bearing inner cylinder 14, and the first end cover 11 and the second end cover 12 are respectively arranged at two ends of the pressure-bearing inner cylinder 14, so that the first end cover 11, the second end cover 12 and the pressure-bearing inner cylinder 14 form a shell structure 01 as shown in fig. 5. The pressure-bearing inner cylinder 14 can be a thick cylinder made of metal, has extremely strong pressure resistance and corrosion resistance, can bear the pressure of 8000m water depth, and resists the corrosion of seawater, thereby effectively protecting the photoelectric component 13 inside.
The first end cover 11 and the second end cover 12 are provided with through holes, the size and shape of the through holes are matched with those of the submarine cable 40a and the submarine cable 40b, thus, the submarine cable 40a can enter the housing structure 01 through the through hole of the first end cap 11, the submarine cable 40b can enter the housing structure 01 through the through hole of the second end cap 12, meanwhile, the submarine cables 40a and 40b are adapted to the through holes in size and shape to reduce gaps between the submarine cables and the through holes, and at this time, the first sealing structure 02 can be formed by the shell structure 01 and the submarine cables 40a and 40b to seal the photoelectric components 13 inside the first sealing structure, meanwhile, the submarine cable 40a and the submarine cable 40b can be electrically connected through the photoelectric component 13, and an optical signal transmitted from the submarine cable 40a is amplified in output optical power and then output by the submarine cable 40b under the action of the photoelectric component 13. Of course, in order to complete the electrical connection between the submarine cable and the photovoltaic module 13, the first and second end caps 11 and 12 are also provided with some electrical connection devices, such as optical fiber connection devices, for electrically connecting with the tail cables of the submarine cables 40a and 40b, and these electrical connection devices are selected according to the type of submarine cable to be connected.
In some embodiments, the outer diameter and shape of the first end cap 11 and the second end cap 12 are designed to meet a predetermined size specification, such as the rules set by the UJ union (refer to the design of the end cap of the UJ joint), so that the housing structure and the optoelectronic module can be separately assembled in a laboratory, and on-site assembly can be avoided, thereby improving sealing and reliability, and the first end cap and the second end cap can be adapted to various submarine cables meeting the same predetermined size specification, thereby improving the application range of the balanced amplification device for small submarine cable transmission signals.
As can be seen from the first seal structure 02, the first seal structure 02 includes a seam between the first end cap 11 and the pressure-receiving inner cylinder 14, a seam between the second end cap 12 and the pressure-receiving inner cylinder 14, and the like, which causes poor sealing performance of the first seal structure 02, and in order to improve the sealing performance of the first seal structure 02, a potting film 15 may be wrapped around the first seal structure 02 formed by the first end cap 11, the second end cap 12 and the pressure-receiving inner cylinder 14, as shown in fig. 3. The injection film 15 is an integrally formed structure, so that a seam of the injection film 15 itself is avoided, and the sealing effect of the injection film 15 is improved. The two ends of the filling film 15 are respectively attached to the first end cover 11 and the second end cover 12, so that a second sealing structure 03 as shown in fig. 6 is formed outside the first sealing structure 02, therefore, a seam between the first end cover 11 and the pressure-bearing inner cylinder 14 and a seam between the second end cover 12 and the pressure-bearing inner cylinder 14 can be wrapped in the filling film 15, seawater is separated from the first sealing structure 02 through the filling film 15, the seawater, harmful gas and the like are prevented from permeating into the shell structure, meanwhile, the protective gas filled in the device is prevented from leaking, and the device also has an insulating function, so that the electric connection effectiveness between submarine cables is ensured.
In the above-mentioned small-sized submarine cable signal transmission equalization amplification device 1, the tightness between the submarine cable and the small-sized submarine cable signal transmission equalization amplification device 1 still needs to be ensured through the matching between the submarine cable and the via hole of the end cover, however, in the deep sea environment, it is relatively difficult to ensure the matching between the submarine cable and the via hole of the end cover, therefore, the seam between the submarine cable and the via hole of the end cover needs to be sealed, a perfusion film structure as shown in fig. 7 can be adopted, for the convenience of analysis, the perfusion film 15 can be divided by the dotted line as shown in fig. 7, and it is noted that the division here is only for convenience of explanation and is not for physical division, so the perfusion film 15 still has an integrally formed structure. According to the division of dotted lines in fig. 7, it can be known that the perfusion film 15 includes a first wrapping head 151, a wrapping body 152 and a second wrapping head 153, one side of the first wrapping head 151 and one side of the second wrapping head 153 are respectively connected to two ends of the wrapping body 152, wherein the first wrapping head 151 is attached to the first end cover 11, the second wrapping head 153 is attached to the second end cover 12, the wrapping body 152 is attached to the pressure-bearing inner cylinder 14, and a structure formed by the first wrapping head 151, the wrapping body 152 and the second wrapping head 153 is equivalent to the perfusion film structure in fig. 3, and at this time, the structure can only wrap a seam between the first end cover 11 and the pressure-bearing inner cylinder 14 and a seam between the second end cover 12 and the pressure-bearing inner cylinder 14. In order to wrap the seam between the submarine cable 40a and the first end cap 11, and the seam between the submarine cable 40b and the second end cap 12, as shown in fig. 7, a first extension body 154 and a second extension body 155 are additionally arranged on the perfusion film 15, the first extension body 154 is connected to the other side of the first wrapping head 151, and the second extension body 155 is connected to the other side of the second wrapping head 153, wherein the first extension body 154 and the second extension body 155 are respectively attached to two adjacent submarine cables, that is, the first extension body 154 is attached to the submarine cable 40a, and the second extension body 155 is attached to the submarine cable 40 b. The perfusion film 15 formed by the first wrapping head 151, the wrapping body 152, the second wrapping head 153, the first extension body 154 and the second extension body 155 is also of an integrally formed structure, so that the seam of the perfusion film 15 itself is eliminated, and the seam between the first end cover 11 and the pressure-bearing inner cylinder 14, the seam between the second end cover 12 and the pressure-bearing inner cylinder 14, the seam between the submarine cable 40a and the first end cover 11, and the seam between the submarine cable 40b and the second end cover 12 can be wrapped by the perfusion film 15 shown in fig. 7, so that the direct contact between the seawater and the seams can be effectively prevented, and the tightness of the balanced amplification device 1 for small submarine cable transmission signals can be improved.
As can be seen from the balanced amplification device for small submarine cable transmission signals shown in fig. 7, the cross-sectional dimension of the first elongated body 154 adjacent to the submarine cable 40a is larger than that of the submarine cable 40a, and the cross-sectional dimension of the second elongated body 155 adjacent to the submarine cable 40b is larger than that of the submarine cable 40b, so that a size fault exists between the first elongated body 154 and the submarine cable 40a, and a size fault exists between the second elongated body 155 and the submarine cable 40b, so that a large shear stress is easily generated at the size fault, and in application, due to scouring of seawater and the like, the size faults are easily broken under the action of the shear stress. In order to improve the connection reliability between the small sea cable signal equalizing and amplifying device 1 and the sea cable 40a and the sea cable 40b, a structure as shown in fig. 8 may be adopted, that is, the first extending body 154 and the second extending body 155 may be designed to be a transition structure, that is, the radial dimensions of the first extending body 154 and the second extending body 155 are gradually reduced along the direction away from the inclusion body 152, so as to eliminate the dimension fault existing between the first extending body 154 and the sea cable 40a, and the dimension fault existing between the second extending body 155 and the sea cable 40b, thereby improving the connection reliability between the small sea cable signal equalizing and amplifying device 1 and the sea cable.
The equalization amplification device 1 for small submarine cable transmission signals is in direct contact with the outside and is an infusion film 15, and the infusion film 15 is low in rigidity, so that the equalization amplification device 1 for small submarine cable transmission signals is easy to be damaged by being hit by external force in the processes of transportation, laying, use and the like, in order to prolong the service life of the equalization amplification device 1 for small submarine cable transmission signals, the equalization amplification device for small submarine cable transmission signals shown in fig. 9 can be adopted, namely, an armor cylinder 16 is sleeved on the outer side of the second sealing structure, and the armor cylinder 16 is made of a material with high rigidity and strong corrosion resistance. In order to fully protect the second sealing structure within the armor barrel 16, it is necessary to ensure that the length dimension of the armor barrel 16 along the central axis is greater than or equal to the length dimension of the second sealing structure along the central axis.
The potting film 15 is generally prepared by injection molding, and in the injection molding process, the molding of the potting film 15 is constrained by the pressure-bearing inner cylinder 14, the first end cover 11, the second end cover 12 and the armor cylinder 16, and the potting is generally selected to be performed at two ends of the armor cylinder 16, so that for the preparation of the potting film 15, an armor cylinder structure as shown in fig. 10 can be adopted, for the analysis, the armor cylinder 16 can be divided by a dotted line as shown in fig. 10, and the division here is only for convenience and is not for physical division. According to the division of the dotted lines in fig. 10, it can be known that the armor cylinder 16 includes a first cylinder 161, a second cylinder 162, and a third cylinder 163, the first cylinder 161 and the second cylinder 162 are respectively disposed at two ends of the third cylinder 163, wherein the third cylinder 163 is sleeved outside the potting film 15 corresponding to the pressure-bearing inner cylinder 14, and the radial dimensions of the first cylinder 161 and the second cylinder 162 are gradually increased along the direction away from the third cylinder 163, so that a larger operable space is formed between the first cylinder 161 and the first end cap 11, and between the second cylinder 162 and the second end cap 12, so as to facilitate the operations of placing a mold, pouring a melt material, and the like during injection molding of the potting film 15, and also facilitate the setting of a clamp during detachment of the armor cylinder 16, and the connection with the connection members at two sides of the armor cylinder 16, and the like.
The submarine cable is usually stored in a curled manner, and the long-time curling causes the submarine cable to have a certain degree of bending after being laid, and the bending is more obvious as the curvature of the submarine cable is smaller and the closer to the small submarine cable signal transmission equalization amplification device, so the bent submarine cable can directly influence the transmission quality of the optical signal in the submarine cable, therefore, in order to improve the bending problem at the connection position of the submarine cable and the small submarine cable signal transmission equalization amplification device, a bending limiter can be added between the submarine cable and the small submarine cable signal transmission equalization amplification device, taking the small submarine cable signal transmission equalization amplification device shown in fig. 10 as an example for explanation, the small submarine cable signal transmission equalization amplification device shown in fig. 11 can be used, and the first bending limiter 17 and the second bending limiter 18 can be added in the small submarine cable signal transmission equalization amplification device 1, the first bending limiter 17 and the second bending limiter 18 are respectively arranged at both ends of the armor cylinder 16, so that the submarine cable 40a can enter the second sealing structure 03 through the first bending limiter 17, the submarine cable 40b can enter the second sealing structure 03 through the second bending limiter 18, the submarine cable 40a and the submarine cable 40b are straightened by the first bending limiter 17 and the second bending limiter 18, respectively, so as to effectively limit the submarine cables (the submarine cable 40a and the submarine cable 40b) to be in a state of being parallel to the central axis within a certain distance (the first bending limiter 17 and the second bending limiter 18) before entering the second sealing structure, and enter the second sealing structure in a manner of being coaxial with the central axis, so as to correct the bending of the submarine cable due to the winding accommodation and the like, so that the submarine cable can be better fitted with the first end cap 11, the second end cap 12 and the pouring film 15, the gap generated by bending the submarine cable is reduced, and the sealing performance is improved. In some embodiments, the bending limiter may also be configured based on the small submarine cable signal equalization amplifying device shown in fig. 3, 7, 8, and 9, wherein it is required to ensure that the size and shape of the end face of the bending limiter are matched with the size and shape of the connected components, and the specific structure is similar to the small submarine cable signal equalization amplifying device shown in fig. 11, and the two devices are not unfolded one by one.
Further, in order to avoid the radial dimension difference between the submarine cable and the bending limiter, a buffer may be added between the submarine cable and the bending limiter, as shown in fig. 11, a first buffer 19 is added between the submarine cable 40a and the first bending limiter 17, and a second buffer 110 is added between the submarine cable 40b and the second bending limiter 18, wherein the radial dimension of the first buffer 19 and the radial dimension of the second buffer 110 are gradually reduced along a direction away from the second sealing structure to form a dimension transition between the submarine cable and the bending limiter, so as to enhance the connection strength between the submarine cable and the small submarine cable transmission signal equalization amplification device. In some embodiments, the buffer may also be configured based on the small submarine cable signal equalization amplifying device shown in fig. 3, 7, 8, and 9, wherein it is required to ensure that the size and shape of the end surface of the buffer at the end not connected with the submarine cable are matched with the size and shape of the connected component, and the specific structure is similar to the small submarine cable signal equalization amplifying device shown in fig. 11, and the buffer is not unfolded one by one.
