[0027] The primary function of optical fiber cables is to transmit optical signals. As a communication transmission medium, optical fiber cables play a crucial role in multiple fields, with a wide range of applications. Optical fiber cables utilize optical fibers to transmit optical signals, which are converted into light pulses and transmitted through the fiber via total internal reflection. Upon reaching their destination, they are converted back into electrical signals, thus achieving fast and reliable information transmission. Optical fiber cables possess advantages such as high bandwidth, long transmission distance, low loss, and strong anti-interference capabilities, making them the preferred technology for modern communication. Their applications are extensive: In the communications field, optical fiber cables are the infrastructure for building global internet and mobile communication networks. Whether it's international submarine optical cables or urban fiber optic networks, they provide high-speed, reliable communication services. Furthermore, optical fiber cables are widely used in broadcasting, wireless communication, and data centers, such as for the transmission of high-definition video and live broadcast signals, and high-speed interconnection of servers within data centers. In the medical field, optical fiber cables play a vital role in endoscopy and minimally invasive surgery, using fiber bundles to transmit images and lasers for procedures such as gastroscopy, colonoscopy, and arthroscopy. Simultaneously, optical fibers can also guide lasers for precise surgeries, such as ophthalmic surgery and tumor ablation. Industry and Sensing: Fiber optic sensors are widely used to monitor parameters such as temperature, pressure, and deformation, for applications in bridges, oil and gas pipelines, and power facilities. Fiber lasers are also used in industrial processing such as metal cutting and welding. Energy Sector: Fiber optic cables play a crucial role in power system monitoring, used for high-voltage transmission line temperature monitoring and substation communication. Furthermore, in oil exploration, fiber optic sensors are used to monitor oil well pressure and temperature. Scientific Research and Special Applications: Fiber lasers have wide applications in materials processing and scientific research experiments. Simultaneously, fiber optics serve as the transmission channel for quantum key distribution in quantum communication. Additionally, fiber optics are used in decoration and lighting, such as architectural landscape lighting and art installations. In conclusion, fiber optic cables, with their unique advantages, play a vital role in multiple fields and are an indispensable key technology for modern communication and information transmission.

[0028] The main scenarios where fiber optic cables need to be spliced ​​include the following: High-density cabling in data centers: Within data centers, servers, storage devices, and network switches require a large amount of data transmission. To save space, increase cabling density, and simplify management, high-density fiber optic connectors such as MPO / MTP are often used. In these scenarios, splicing fibers (such as MPO splicing fibers) can be used to connect MPO / MTP connectors of different densities to optimize fiber utilization and data link aggregation.

[0029] For long-distance transmission relay, when the transmission distance of the optical cable exceeds the nominal transmission distance of the transceiver, a relay using a fiber optic adapter and a fiber optic transceiver can be used to achieve long-distance signal transmission. Two transceivers are connected back-to-back, and the transmission path is extended using the fiber optic adapter, thus ensuring stable data transmission.

[0030] Network upgrades and expansions have become commonplace with the continuous development of network technology and the increase in data traffic. During these processes, it may be necessary to connect existing fiber optic cables to new equipment or a new network architecture. In this case, fiber optic adapters can be used to adapt to different specifications and types of fiber optic connectors, ensuring a smooth transition and compatibility between the old and new networks.

[0031] In surveillance network construction projects such as smart cities and highway monitoring, monitoring points are typically scattered and far from the monitoring center. To achieve long-distance transmission of monitoring signals, a combination of fiber optic transceivers and fiber optic adapters can be used. The fiber optic transceivers convert the video signals from the monitoring points into optical signals for transmission, and then the signals are connected to the fiber optic transceivers at the monitoring center via fiber optic adapters, ultimately converting them into electrical signals for use by the monitoring center.

[0032] Single-mode to multi-mode fiber conversion is used when single-mode to multi-mode fiber connections are required between networks. These converters internally incorporate fiber optic switching functionality to achieve signal conversion and transmission between single-mode and multi-mode fibers.

[0033] In summary, fiber optic cable switching is required in a variety of scenarios, primarily including high-density cabling in data centers, long-distance transmission relay, network upgrades and expansions, monitoring network construction, and single-mode / multimode fiber conversion. In these scenarios, switching fibers and related fiber optic transceivers and converters play a crucial role.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The waterproof optical cable box in the first embodiment of this utility model includes: an upper shell 1, a lower shell 2, and a sealing mechanism 4. The upper shell 1 and the lower shell 2 are detachably connected, and together they define a sealed chamber 31. When defining the sealed chamber 31 using the upper shell 1 and the lower shell 2, various methods such as clamps or clips can be used to fix the upper shell 1 and the lower shell 2 together and define the sealed chamber 31. When using the waterproof optical cable box, the upper shell 1 and the lower shell 2 are first separated, the cable connection point is placed in the lower shell 2 or the upper shell 1, and then the upper shell 1 and the lower shell 2 are fixed together to form the sealed chamber 31, ensuring that the cable connection point is within the sealed chamber 31. Furthermore, to ensure the sealing performance of the sealed chamber 31, an elastic sealing strip can be provided at the abutment position of the upper shell 1 and the lower shell 2, thereby further improving the sealing performance of the sealed chamber 31.

[0035] Two through holes 32 are provided on the sealed chamber 31 for cables to pass through. The upper shell 1 and the lower shell 2 also define two water-proof chambers 33, which are located at the ends of the through holes 32 facing outwards from the sealed chamber 31. Each of the two water-proof chambers 33 is equipped with a sealing mechanism 4, which includes an elastic block 41 and a pressing member 11. The elastic block 41 is elastically deformable and can be made of a gel material. A through hole 42 is provided on the elastic block 41 for the cable to pass through. The pressing member 11 is fixed to the upper shell 1 to press the elastic block 41, which abuts against one end of the through hole 32. The through holes 32 allow the cable to enter the sealed chamber 31, whereby splicing and other operations can be performed. By setting up a waterproof chamber 33, an elastic block 41, and a pressing element 11, the cable has a strong sealing performance when passing through the wire hole 32, thereby greatly improving the sealing and waterproof performance of the sealed chamber 31.

[0036] According to some embodiments of this utility model, the optical cable waterproof box further includes a coaxial mechanism 5. The coaxial mechanism 5 is disposed on the side of the sealing mechanism 4 opposite to the sealing chamber 31. The coaxial mechanism 5 includes multiple abutment blocks 51, which are slidably disposed on the lower housing 2 along the radial direction of the cable through hole 32. The coaxial mechanism 5 is used to fix the position of the cable, preventing the cable from shaking in the sealing chamber 31 or the waterproof chamber 33, and preventing the cable from dynamically squeezing the elastic block 41, thereby making the sealing chamber 31 have more stable sealing and waterproof performance.

[0037] According to some embodiments of this utility model, the upper housing 1 and the lower housing 2 together define a coaxial chamber 34. The coaxial chamber 34 is disposed on the side of the water-proof chamber 33 opposite to the sealed chamber 31, and the coaxial mechanism 5 is disposed within the coaxial chamber 34. The coaxial chamber 34 provides a better working environment for the coaxial mechanism 5, making the coaxial mechanism 5 more stable and preventing debris from affecting the coaxiality of the cable.

[0038] According to some embodiments of this utility model, the optical cable waterproof box further includes a buffer part 6, which is sleeved on the cable and fixedly mounted on the lower housing 2. The buffer part 6 is located on the side of the coaxial mechanism 5 facing away from the sealed chamber 31. When the cable is affected by the external environment, the cable will shake. When the cable shakes, it will exert a large compressive force on the upper housing 1 and the lower housing 2, which can easily damage the upper housing 1 and the lower housing 2. Therefore, by setting the buffer part 6 on the cable, the cable will be squeezed against the buffer part 6 first when shaking, thereby avoiding damage to the optical cable waterproof box and protecting the cable from damage. Specifically, the buffer part can be set as a rubber block.

[0039] According to some embodiments of the present invention, the abutment block 51 is provided with an abutment surface 52, which is used to abut against the cable, and a protrusion 53 is provided on the abutment surface 52. In order to prevent the cable from sliding along the axial direction of the cable in the coaxial mechanism 5, a protrusion 53 is provided on the abutment surface 52, thereby enhancing the friction between the abutment surface 52 and the cable.

[0040] According to some embodiments of this utility model, the coaxial mechanism 5 further includes a restraining member, which is sleeved on the outside of the plurality of abutment blocks 51 to bring the plurality of abutment blocks 51 closer together. When coaxially positioning the cable, the abutment blocks 51 need to be driven to slide, thereby moving the abutment blocks 51 further apart and increasing the gap between the abutment blocks 51, allowing the cable to pass through the gap between the abutment blocks 51 and enter the center position of the abutment blocks 51. At this time, by driving the abutment blocks 51, the abutment blocks 51 are brought closer together and abut against the cable, thus coaxially fixing the cable. The abutment blocks 51 can also be fixed by the restraining member, for example, by using cable ties to tighten and fix the plurality of abutment blocks 51.

[0041] According to some embodiments of this utility model, the sealing mechanism 4 further includes a hard shell 43, which restricts the groove. An elastic block 41 is disposed in the groove, and the through hole 42 on the elastic block 41 is exposed outside the groove. A buckle 46 is provided on the outer side of the hard shell 43, which is used to engage with the water-proof chamber 33. By providing the groove, the elastic block 41 can be more easily placed and removed from the water-proof chamber, and the sealing mechanism 4 can be better fixed in the water-proof chamber 33. When the sealing mechanism 4 is fixed in the water-proof chamber 33, the buckle 46 engages and fixes the sealing mechanism 4 in the water-proof chamber 33. By pressing the hard shell 43, the buckle 46 can be disengaged, making it easier to remove the sealing mechanism 4 from the water-proof chamber 33. In addition, the groove formed on the hard shell 43 limits the deformation range of the elastic block 41 when pressed by the pressing member 11, thereby obtaining better sealing and waterproof performance.

[0042] According to some embodiments of this utility model, the hard shell 43 is further provided with a flared portion, which is disposed on the opening of the groove and is inclined outward along the direction of the opening of the groove. By providing a flared portion on the hard shell 43, the elastic block 41 can be placed more easily in the groove. At the same time, when the hard shell 43 is removed from the water-proof chamber 33, the flared portion can be pressed, thereby making it easier to disengage the buckle 46 from the snap-fit ​​state.

[0043] According to some embodiments of this utility model, the elastic block 41 includes an upper block portion 44 and a lower block portion 45. The upper block portion 44 is provided with a first arc-shaped groove, and the lower block portion 45 is provided with a second arc-shaped groove. The first and second arc-shaped grooves together define a through hole 42. When a cable is placed into the through hole 42, it can pass through the through hole 42 from its end; alternatively, a slit can be cut in the elastic block 41, and the cable can be squeezed into the through hole 42 by the deformation of the elastic block 41. Furthermore, by dividing the elastic block 41 into an upper block portion 44 and a lower block portion 45, it is more convenient to confine the cable within the through hole 42.

[0044] According to some embodiments of this utility model, the upper shell 1 and the lower shell 2 are rotatably connected. A latch 8 is provided on the upper shell 1 to fix the upper shell 1 and the lower shell 2 together. The rotatable connection of the upper shell 1 and the lower shell 2 makes it easier to separate and merge them. Simultaneously, the latch 8 facilitates the fixing of the upper shell 1 and the lower shell 2, and more easily restricts the sealing chamber 31. Furthermore, a sealing strip 7 can be provided at the point where the upper shell 1 and the lower shell 2 abut against each other, thereby improving the sealing performance and waterproofing of the sealing chamber.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
