Description

Technical Field

[0001] This application relates to the field of waterproof technology for outdoor communication equipment, and particularly to a network device. Background Technology

[0002] Network equipment deployed in outdoor environments, such as cable-mounted equipment, pole-mounted equipment, and wall-mounted equipment, includes a waterproof housing. The housing typically consists of a base and a top cover, which are detachable and fixed to the base. All functional modules within the network equipment, such as power modules, electrical signal modules, and optical signal modules, are housed within the base. A sealing ring is installed at the connection between the top cover and the base to prevent water, dust, and other environmental contaminants from entering the housing and affecting the normal operation of the internal functional modules.

[0003] For example, in a passive optical network (PON), an outdoor optical line terminal (OLT) is used for downlink connections to user-end optical network terminals (ONTs) and uplink connections to switches in the central equipment room. This type of outdoor OLT contains modules for processing optical signals, modules for processing electrical signals, and modules for performing photoelectric and electro-optical conversions. All of these modules are deployed in a waterproof enclosure.

[0004] Outdoor OLTs, during commissioning, maintenance, and new user network access scenarios, often require technicians to open the waterproof casing to access internal functional modules. Frequent disassembly or improper handling by technicians can compromise the waterproof performance of the casing. For example, a faulty or damaged seal between the top cover and base can reduce or even destroy the casing's waterproofing. Once the casing's waterproofing is compromised, it will affect the internal functional modules. In severe cases, water ingress can cause short circuits in some modules, leading to carbonization and failure. Utility Model Content

[0005] This application provides a network device, which includes multiple functional modules and multiple compartments, wherein the multiple functional modules are arranged in the multiple compartments;

[0006] Each of the multiple compartments includes a compartment cover and a compartment seat, the compartment cover and the compartment seat are fixedly connected, and a sealing element is arranged at the connection between the compartment cover and the compartment seat. The functional modules in different compartments are connected by a waterproof connector.

[0007] In the solution presented in this application, the network device includes multiple compartments, and multiple functional modules within the network device are distributed across these compartments. Each compartment is independently sealed. For example, each compartment can be sealed according to the waterproofing requirements of the deployed components. For instance, the compartment containing active modules with higher waterproofing requirements can have a higher waterproofing rating, while the compartment containing passive modules with less stringent waterproofing requirements can have a slightly lower rating. Furthermore, even if the sealing performance of one or more compartments deteriorates due to frequent opening or operator error, it will only affect the functional modules within that compartment and will not affect the normal operation of functional modules in other compartments, thus improving the overall sealing performance of the network device.

[0008] In one implementation, the cover and seat of at least one of the plurality of compartments are fixedly connected in a detachable manner.

[0009] In one implementation, each functional module is arranged in a compartment, or functional modules requiring the same level of waterproofing are arranged in the same compartment.

[0010] In the solution shown in this application, each functional module is deployed in a separate compartment, and each compartment is independently sealed. Therefore, even if the waterproofing of one compartment fails, it is not likely to affect the functional modules in other compartments.

[0011] In the solution shown in this application, functional modules with high requirements for waterproofing and dustproofing can be arranged in a high-waterproofing compartment, while functional modules with less stringent requirements for waterproofing and dustproofing can be arranged in a lower-waterproofing compartment.

[0012] In one implementation, the plurality of functional modules include active modules and passive modules, which are arranged in different compartments.

[0013] In the solution presented in this application, the active module has a higher requirement for waterproofing, while the passive module has a lower requirement. Therefore, the active and passive modules can be arranged in different compartments. For example, all active modules can be arranged in the same compartment, and all passive modules can be deployed in another compartment. Deploying the active and passive modules in different compartments also reduces mutual influence and interference between the active and passive modules.

[0014] In one implementation, an active device is arranged in the compartment where the passive module is located, and the active device is sealed by a sealing structure.

[0015] In the solution shown in this application, one or two active devices may also be arranged in the compartment where the passive module is located. In this case, the active devices can be sealed separately in the compartment where the passive module is located by a sealing structure. For example, the active devices can be protected by a waterproof cap or waterproof cover.

[0016] In one implementation, the network device has photoelectric conversion and electro-optical conversion functions, the active module includes devices for performing photoelectric conversion, devices for electro-optical conversion, and devices for electrical signal processing, and the passive module includes optical fiber and optical fiber adapter.

[0017] In one implementation, the plurality of compartments includes a first compartment and a second compartment, wherein the functional modules in the first compartment and the functional modules in the second compartment are connected.

[0018] The waterproof connector is installed on the walls of both the first and second compartments. The waterproof connector is used for cables to pass through, and the cables are pressed into the waterproof connector.

[0019] The waterproof connector has a cable pass-through hole for the cable to pass through.

[0020] In the scheme shown in this application, waterproof connectors are installed on the walls of the first compartment and the second compartment. Alternatively, waterproof connectors can be installed on the common wall of the first and second compartments, with one end of the waterproof connector located inside the first compartment and the other end located inside the second compartment. Cables in the first compartment pass through the waterproof connector and enter the second compartment.

[0021] In the scheme shown in this application, waterproof connectors are installed on both the walls of the first and second compartments. Alternatively, waterproof connectors can be installed on different walls of the first and second compartments respectively. One end of the waterproof connector on the wall of the first compartment is inside the first compartment, and the other end is outside the first compartment. One end of the waterproof connector on the wall of the second compartment is inside the second compartment, and the other end is outside the second compartment. Cables inside the first compartment pass through the waterproof connector on the wall of the first compartment, and then through the waterproof connector on the wall of the second compartment to enter the second compartment.

[0022] In either case, the waterproof connector is sealed to the wall of the compartment, and the cable is also pressed into the cable hole of the waterproof connector, so that the first compartment and the second compartment achieve both waterproof isolation and signal transmission.

[0023] In one implementation, the plurality of compartments includes a first compartment and a second compartment, wherein the functional modules in the first compartment and the functional modules in the second compartment are connected.

[0024] The waterproof connector is installed on the walls of both the first and second compartments, and the waterproof connector is used for pluggable connection with the connector on the cable.

[0025] The waterproof connector has two interfaces.

[0026] In the scheme shown in this application, waterproof connectors are installed on the walls of both the first and second compartments. Alternatively, waterproof connectors can be installed on the common wall of the first and second compartments. One interface of the waterproof connector is located in the first compartment, and the other interface is located in the second compartment. The connector on the cable in the first compartment is inserted into the interface of the waterproof connector, and the connector on the cable in the second compartment is inserted into the interface of the waterproof connector.

[0027] In the scheme shown in this application, waterproof connectors are installed on both the walls of the first and second compartments. Alternatively, waterproof connectors can be installed on different walls of the first and second compartments respectively. One interface of the waterproof connector on the first compartment wall is located inside the first compartment, and the other interface is located outside the first compartment. Similarly, one interface of the waterproof connector on the second compartment wall is located inside the second compartment, and the other interface is located outside the second compartment. The connector on the cable inside the first compartment is inserted into the interface of the waterproof connector on the first compartment wall, and the connector on the cable inside the second compartment is inserted into the interface of the waterproof connector on the second compartment wall. These two waterproof connectors are also connected by a cable.

[0028] In either case, the waterproof connector is sealed on the wall of the compartment, and the cable connector is also sealed to the waterproof connector, so that the first and second compartments are both waterproofly isolated and can transmit signals.

[0029] In one implementation, the openings of the first compartment seat and the second compartment seat face opposite directions, and the bottoms of the first compartment seat and the second compartment seat form a common wall between the first and second compartments.

[0030] In the scheme shown in this application, the openings of the first compartment and the second compartment face opposite directions. For example, one opening faces upward and the other faces downward, or one opening faces left and the other faces right. The first compartment and the second compartment are arranged back to back. In this case, the common wall of the first compartment and the second compartment is the bottom of the two compartments. The bottom of the first compartment has a through-thickness mounting opening, and a waterproof connector can be sealed and installed at the mounting opening.

[0031] In one implementation, at least one of the plurality of compartments has an idle interface, which is fitted with a waterproof cap.

[0032] In the solution shown in this application, the idle interface can be an interface used during testing or a spare interface. In most cases, it is in an idle state. In this case, in order to prevent water and dust from entering the idle interface, a waterproof cap can be installed on the idle interface to achieve waterproofing and dustproofing.

[0033] In one implementation, the plurality of compartments includes a main compartment and at least one secondary compartment, wherein the at least one secondary compartment is located outside the main compartment, or the at least one secondary compartment is located inside the main compartment.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0049] This embodiment relates to a network device, specifically a network device deployed in an outdoor environment, such as a network device installed on a utility pole, a network device hung on a cable, or a network device mounted on an outdoor wall.

[0050] As an example, network equipment can be an outdoor optical line terminal (OLT) in a fiber to the home / office (FTTH / O) network architecture.

[0051] like Figure 1 The diagram shown is a schematic of the FTTH / O system architecture. (Reference) Figure 1 As shown, upstream network-side equipment (such as switches and routers) is deployed in a central office (CO), connecting to downstream ONTs via an OLT and an optical distribution network (ODN). The ONTs are deployed in homes or offices. The ODN includes passive optical splitters for optical power distribution, a backbone fiber connecting the passive optical splitters and the OLT, and branch fibers connecting the passive optical splitters and the ONTs. When transmitting downlink signals, the downlink signal sent by the OLT is transmitted to each ONT through the passive optical splitter, and each ONT selectively receives the downlink data belonging to itself from the downlink signal. When transmitting uplink signals, the uplink signals sent by N ONTs are combined into a single optical signal by the passive optical splitter and transmitted to the OLT.

[0052] refer to Figure 1As shown, the OLT is connected to the downstream optical splitter or ONT via optical fiber, and the OLT is connected to the upstream switch via optical fiber. The OLT is used to aggregate and manage traffic. It is a network device with photoelectric conversion and electro-optical conversion functions. Therefore, the functional modules of the OLT will include modules for processing electrical signals, modules for processing optical signals, and modules for performing photoelectric conversion and electro-optical conversion.

[0053] To prevent rain and moisture from affecting electrical signals in outdoor OLTs, which could cause short circuits and lead to carbonization failure, the outer casing of outdoor OLTs needs to be sealed. Therefore, all modules inside the OLT, including those that process electrical signals, optical signals, and perform photoelectric and electro-optical conversions, are housed within the casing. Sealing rings are also required at the connection points between the top cover and the base of the casing.

[0054] During maintenance and repair of individual modules within the OLT, the waterproof housing needs to be opened. This is also necessary during network deployment and network performance testing. Frequent opening and closing of the housing can affect the seal between the top cover and the base, and improper installation by technicians can result in the seal not being installed correctly. Damage to the waterproof seal, or improper installation, reduces the waterproof rating of the housing, allowing moisture from the external environment to enter. Over time, this moisture can cause short circuits in modules involved in electrical signal processing, leading to module carbonization and failure.

[0055] Therefore, this embodiment provides a network device that includes multiple compartments, each of which is independently sealed. Thus, opening one compartment does not affect the other compartments, and even if one compartment becomes damp, it will not cause all functional modules to short-circuit and carbonize.

[0056] like Figure 2 The diagram shown is a structural schematic of a network device. (Refer to...) Figure 2 As shown, the network equipment includes multiple compartments 1. Figure 2 The diagram illustrates two compartments 1, each including a cover 11 and a base 12. The cover 11 and base 12 are fixedly connected. For example, the base 12 has a storage opening, and the cover 11 can be placed over the opening of the base 12 and fixedly connected to it. Alternatively, the cover 11 and base 12 of each compartment 1 may be fixedly connected in a detachable manner. Or, for example, the cover and base of some compartments may be fixedly connected in a detachable manner, while the cover and base of other compartments may be fixedly connected by welding. For compartments that are unlikely to be opened in the future, the cover and base may be welded together, riveted together, or glued together.

[0057] The detachable fixing method can be a combination of screws and screw holes, a snap-fit ​​method, or a clamp method.

[0058] Since the network equipment is deployed outdoors, each compartment needs to have certain waterproof and dustproof functions. Therefore, the compartment covers and bases are sealed at the joints using sealing components.

[0059] In one example, the bin cover and bin seat are detachably fixed together, and the sealing element can be a sealing ring. For example, the bin seat has a sealing groove at the bin opening, and a sealing ring is arranged in the sealing groove. After the bin cover is fixed to the bin seat, the sealing ring is pressed against the joint between the bin cover and the bin seat, filling the interface gap at the joint. The sealing ring can also be arranged on the bin cover. Alternatively, sealing rings can be arranged on both the bin cover and the bin seat, so as to achieve a double seal between the bin cover and the bin seat.

[0060] In another example, the bin cover and bin seat are fixedly connected by welding, and the sealant can be a sealant applied to the joint between the bin cover and bin seat.

[0061] In one example, for a detachable bin cover and bin seat, one side of the bin cover and one side of the bin seat can be connected by hinges. This way, when technicians open the bin at height to carry out operations, the bin cover and bin seat are still in the connected state, and the bin cover is not easy to fall off.

[0062] In one example, the network device may include multiple functional modules, which are deployed in multiple compartments. For instance, one functional module may be deployed in one compartment, so that maintenance and repair of each functional module only requires opening the compartment containing that functional module, without affecting the protection of other functional modules.

[0063] For example, functional modules with the same waterproofing requirements can be arranged in the same compartment. In this way, functional modules with higher waterproofing and dustproofing requirements can be placed in compartments with higher waterproofing levels, while functional modules with lower waterproofing and dustproofing requirements can be placed in compartments with lower waterproofing levels.

[0064] For example, the functional modules of a network device used to connect to downstream devices are located in one compartment, while the functional modules used to connect to upstream devices are located in another compartment. In this way, when maintaining, repairing, or deploying the functional modules connected to downstream devices, only the compartment containing that functional module needs to be opened; similarly, when maintaining or repairing the functional modules connected to upstream devices, only the compartment containing that functional module needs to be opened.

[0065] For example, network devices can be devices with photoelectric and electro-optical conversion capabilities, such as OLTs. Their multiple functional modules include active and passive modules. Active modules require an external power supply to operate, while passive modules operate without one. Active modules can include devices for photoelectric conversion, electro-optical conversion, and electrical signal processing, such as optical modules for photoelectric and electro-optical conversion and chips for electrical signal processing. Passive modules can include optical fibers and fiber optic adapters, and may also include resistors, capacitors, and inductors. Active modules have higher waterproofing requirements, while passive modules have lower requirements. Therefore, active and passive modules can be placed in different compartments. For example, all active modules can be placed in one compartment, and all passive modules in another. Deploying active and passive modules in different compartments also reduces mutual influence and interference between them.

[0066] In another example, the compartment containing the passive module may also house one or two active devices. In this case, the active devices can be individually sealed within the passive module compartment using a sealing structure. For example, the active devices can be protected by waterproof caps or covers.

[0067] In another example, if there are unused interfaces in one or more compartments, waterproof caps can be installed on these interfaces to protect them. For example, unused interfaces could be those used during debugging and testing, or they could be spare interfaces. These unused interfaces can be electrical or optical interfaces.

[0068] Network devices function by working together with multiple functional modules. Therefore, functional modules in different compartments are connected. To prevent compartments from interconnecting, functional modules in different compartments are connected by waterproof connectors.

[0069] For example, a waterproof connector is sealed to the wall of a compartment. The waterproof connector may have a cable pass-through hole through which a cable (such as an electrical cable or fiber optic cable) passes and is clamped in place. Specifically, this type of waterproof connector may be a PG connector.

[0070] For example, a waterproof connector is sealed and installed on the wall of the compartment. The waterproof connector has an interface that mates with the connector on the cable, and the connector of the cable is inserted into the interface of the waterproof connector.

[0071] An example of a connection between functional modules in the first compartment and functional modules in the second compartment.

[0072] Waterproof connectors are installed on the walls of both the first and second compartments, for example, such as... Figure 3 As shown, a waterproof connector 2 is installed on the common wall of the first compartment 101 and the second compartment 102. For example, such as... Figure 4 As shown, waterproof connectors 2 are installed on different walls of the first compartment 101 and the second compartment 102, respectively, and are referred to as the first waterproof connector 21 and the second waterproof connector 22. In either case, the waterproof connectors are sealed and fixedly connected to the walls of the compartments.

[0073] For example, the silo wall has an installation port, in which a cylindrical seat with internal threads is installed. The waterproof connector has external threads and can be screwed into the cylindrical seat. The cylindrical seat is sealed to the silo wall using a sealing structure, and the waterproof connector is also sealed to the cylindrical seat using a sealing structure.

[0074] For example, the warehouse wall has an installation port, and there are installation holes on the warehouse wall and around the installation port. The waterproof connector is fixed to the warehouse wall by screws, and a sealing structure is arranged between the waterproof connector and the warehouse wall surface.

[0075] refer to Figure 3 As shown, a waterproof connector 2 installed on the common wall of the first compartment 101 and the second compartment 102 has one end located inside the first compartment 101 and the other end located inside the second compartment 102. The cable connected to the functional module in the first compartment 101 passes through the cable hole of the waterproof connector 2 and enters the second compartment 102 to connect with the functional module in the second compartment 102.

[0076] refer to Figure 4 As shown, one end of the first waterproof connector 21 installed on the wall of the first compartment 101 is located inside the first compartment 101, and the other end is located outside the first compartment 101. One end of the second waterproof connector 22 installed on the wall of the second compartment 102 is located inside the second compartment 102, and the other end is located outside the second compartment. The cables connected to the functional modules inside the first compartment pass through the first waterproof connector installed on the wall of the first compartment, and then through the second waterproof connector 22 installed on the wall of the second compartment 102, and enter the second compartment 102 to connect with the functional modules inside the second compartment 102.

[0077] The above describes a solution for passing cables through a waterproof connector with a cable guide hole. The following describes a solution for inserting the cable connector into a waterproof connector with an interface.

[0078] Waterproof connectors are installed on the walls of both the first compartment 101 and the second compartment 102, for example, Figure 5 As shown, a waterproof connector 2 is installed on the common wall of the first compartment 101 and the second compartment 102. For example, such as... Figure 6As shown, waterproof connectors, denoted as first waterproof connector 21 and second waterproof connector 22, are installed on different walls of the first compartment 101 and the second compartment 102, respectively. In either case, the waterproof connectors are sealed and fixedly connected to the walls of the compartments.

[0079] The waterproof connector has a first interface and a second interface, both of which are used for pluggable connection with the connector on the cable.

[0080] refer to Figure 5 As shown, the first interface of the waterproof connector 2, installed on the common wall of the first compartment 101 and the second compartment 102, is located in the first compartment, and the second interface is located in the second compartment. The connector end of the cable connected to the functional module in the first compartment 101 is inserted into the first interface of the waterproof connector 2, and the connector end of the cable connected to the functional module in the second compartment 102 is inserted into the second interface of the waterproof connector 2.

[0081] refer to Figure 6 As shown, the first interface of the first waterproof connector 21 installed on the wall of the first compartment 101 is located inside the first compartment 101, and the second interface is located outside the first compartment 101. The first interface of the second waterproof connector 22 installed on the wall of the second compartment 102 is located inside the second compartment 102, and the second interface is located outside the second compartment 102. The connector head of the cable connected to the functional module inside the first compartment 101 is inserted into the first interface of the first waterproof connector 21 installed on the wall of the first compartment 101. The connector head of the cable connected to the functional module inside the second compartment 102 is inserted into the first interface of the second waterproof connector 22 installed on the wall of the second compartment. The second interface of the first waterproof connector 21 installed on the wall of the first compartment 101 and the second interface of the second waterproof connector 22 installed on the wall of the second compartment 102 are connected by a jumper wire.

[0082] In another example, cables between different compartments can also be pre-embedded in the bottom of the compartment base or in the compartment wall of the compartment base. For example, cable holes can be drilled in the bottom of the compartment base or in the compartment wall of the compartment base.

[0083] In other examples, functional modules in different compartments can also be wirelessly connected, such as via Wi-Fi or Bluetooth signals.

[0084] Regarding the layout of multiple compartments in a network device: In one example, the front of the network device may have one or more compartments, and the back of the network device may have one or more compartments. The openings on the bases of the compartments located on the front of the network device face opposite directions to the openings on the bases of the compartments located on the back of the network device. In another example, the multiple compartments of the network device may be arranged on either the front or back of the network device; that is, all the compartments are on the same side.

[0085] In another example, multiple compartments may include a main compartment and at least one secondary compartment, such as... Figure 7 As shown, these secondary compartments can all be located within the main compartment, such as... Figure 8 As shown, these auxiliary compartments can all be located outside the main compartment, such as... Figure 9 As shown, some of these auxiliary storage compartments are located inside the main storage compartment, while others are located outside the main storage compartment.

[0086] In one example, to distinguish the functional modules installed in each compartment, markings can be made on the outer surface of the compartment cover, such as etching marks to indicate the deployed functional modules. Alternatively, the network device can be associated with an application, allowing technicians to view the functional modules deployed in each compartment through the application. Or, technicians can record the functional modules deployed in each compartment within the network device during deployment.

[0087] The following section uses an outdoor OLT as an example to introduce an OLT with the above characteristics.

[0088] The OLT (Optical Line Transmission Unit) has photoelectric and electro-optical conversion functions. For example, it converts electrical signals into optical signals, which are then transmitted to the user-side ONT (On-Network Terminal) via optical fiber. It also converts the optical signals sent by the user-side ONT into electrical signals for data processing. Therefore, the OLT includes active and passive modules. The active modules can be arranged in one compartment, and the passive modules can be arranged in another compartment.

[0089] Correspondingly, such as Figure 10 The diagram shown is a structural schematic of the OLT on its first side (e.g., the front side). Figure 11 The diagram shown is a structural schematic of the OLT on the second side (e.g., the back side). (Reference) Figure 10 As shown, the front of the OLT has a compartment for deploying optical fibers, which serves as a passive fiber optic cable tray 110. The walls of the passive fiber optic cable tray 110 are equipped with a first connector for connecting uplink optical cables and a second connector for connecting downlink optical cables. The passive fiber optic cable tray may also contain multiple fiber optic adapters for enabling fiber optic connections.

[0090] In one example, the test network port can be located in the passive fiber optic storage compartment. Technicians at the network deployment site can insert network cables into the port to perform on-site debugging of the OLT. The network port refers to the aforementioned unused interface; when not in use, a dust cap can be inserted into the port.

[0091] refer to Figure 11 As shown, the OLT has a compartment on its back, which serves as the main compartment for deploying active modules; this compartment can be designated as active compartment 120. The active compartment 120 contains a circuit board with chips and an optical cage assembly for connecting the optical modules. The optical cage assembly includes an optical cage and an optical module connector located within it. The optical module connector is connected to the chips via traces on the circuit board. The optical module's connector is inserted into the optical cage and connects to the optical module connector within the cage. The optical port of the optical module is plugged into an optical fiber.

[0092] The optical fiber connected to the optical module in the active fiber optic compartment 120 originates from the passive fiber optic cable compartment 110. A waterproof connector can be installed on the common wall of the active and passive fiber optic cable compartments 120, with the optical fiber passing through the cable guide hole of the waterproof connector. Since the active fiber optic compartment is located on the back of the network equipment and the passive fiber optic cable compartment is on the front, the common wall of the two compartments forms the bottom of both the active and passive fiber optic cable compartments.

[0093] As described above, the walls of the passive fiber optic compartment 110 are equipped with a first connector for connecting uplink optical cables and a second connector for connecting downlink optical cables. The first connector has an interface located outside the passive fiber optic compartment 110 and an interface located inside the passive fiber optic compartment 110. Similarly, the second connector also has an interface located outside the passive fiber optic compartment 110 and an interface located inside the passive fiber optic compartment 110. The optical fiber connecting to the switch has its fiber optic connector inserted into the interface of the first connector located outside the passive fiber optic compartment 110. An optical fiber is also connected to the interface of the first connector located inside the passive fiber optic compartment 110. This optical fiber enters the active compartment 120 through a waterproof connector on the common wall of the passive fiber optic compartment 110 and the active compartment 120. An optical module is arranged inside the active compartment 120. The optical fiber entering the active compartment 120 has its fiber optic connector connected to the optical port of the optical module.

[0094] The optical fiber connecting to the ONT has its end connector plugged into the interface of the second connector located outside the passive fiber optic compartment 110. An optical fiber is also connected to the interface inside the passive fiber optic compartment 110 of the second connector. This optical fiber enters the active compartment 120 through a waterproof connector on the common wall of the passive fiber optic compartment 110 and the active compartment 120. The end connector of the optical fiber entering the active compartment 120 is then connected to the optical port of the optical module.

[0095] As can be seen, in fiber optic network deployment, technicians only need to connect the fiber optic cable to the switch to the first connector, connect the fiber optic cable to the ONT to the second connector, and open the passive fiber optic cable tray 110 to perform fiber optic connection and fiber optic cable tray operations, without needing to open the active fiber optic cable tray 120.

[0096] Therefore, even if technicians frequently open the passive fiber optic compartment, or if the technicians operate improperly, causing the passive fiber optic compartment to become less airtight, it will not affect the active modules inside the active compartment.

[0097] In this embodiment, the network device includes multiple compartments, and multiple functional modules within the network device are distributed across these compartments. Each compartment is independently sealed. For example, each compartment can be sealed according to the waterproofing requirements of the deployed components. For instance, the compartment containing active modules with higher waterproofing requirements can have a higher waterproofing rating, while the compartment containing passive modules with less stringent waterproofing requirements can have a slightly lower rating. Furthermore, even if the sealing performance of one or more compartments deteriorates due to frequent opening or operator error, it will only affect the functional modules within that compartment and will not affect the normal operation of functional modules in other compartments, thus improving the overall sealing performance of the network device.

[0098] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this application should be included within the protection scope of this application.
