Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0018] It should be noted that extended picocells utilize digital technology and are low-power indoor coverage solutions based on fiber optic or network cables for wireless signal transmission and distribution. They are one type of indoor coverage enhancement solution. Specifically, an extended picocell consists of three parts: a picocell host (baseband unit, BBU), extension units (EUs), and remote radio units (RRUs). Due to technological maturity and cost considerations, point-to-point fiber optic interconnection and data transmission are typically used between extended picocell network elements, including between the picocell host and extension units, and between extension units and remote radio units. It should also be noted that a single picocell host can connect to multiple extension units, and each extension unit can connect to multiple remote radio units. Fiber to the Home (FTTH) is a broadband access technology that extends optical fiber directly to a user's home. Its network architecture is mainly based on Passive Optical Network (PON) technology, featuring high efficiency, flexibility, and low cost. An FTTH network typically consists of three main parts: an Optical Line Terminal (OLT), an Optical Distribution Network (ODN), and an Optical Network Unit (ONU). The OLT, ODN, and ONU are interconnected using optical fiber. The OLT performs one or more stages of optical splitting through the ODN and then connects to multiple ONUs to provide broadband access for homes and businesses. The optical splitter is the core device of the ODN, used to distribute the optical signal emitted by the OLT to multiple user terminals.

[0019] However, in related technologies, the simultaneous deployment of extended picocell base stations and FTTH networks (i.e., wireless and wired) typically involves two sets of equipment, two planning and construction schemes, and two site visits, resulting in high engineering construction costs. Therefore, this utility model aims to reduce the construction costs of "wireless + wired" dual-network projects by integrating wireless and wired equipment and using a new cable architecture between the extended unit and the remote unit, combining the access capabilities of hybrid fiber optic cables and easily accessible fiber optic cables. Specifically, the extended unit of the extended picocell base station is interconnected with the remote unit using optical fiber. Furthermore, it exhibits star-shaped networking characteristics, which are very similar to the networking between optical splitters and optical network units in FTTH. Therefore, it is considered to integrate the expansion unit and the optical splitter into a single converged module (i.e., converged device). When constructing a dual network of wireless and wired networks, only one device installation is required to meet the dual network requirements. At the same time, during network cabling, the hybrid optical-electrical cable between the expansion unit and the remote unit, as well as the easily spliced ​​optical cable between the optical splitter and the optical network unit, are merged into a single converged cable (i.e., target cable). In this way, during indoor cabling, only one cabling is required to simultaneously meet the access requirements of both the remote unit and the optical network unit.

[0020] Based on this, the present invention provides a fusion device, referring to... Figure 1 As shown, the fusion device 1 includes a target module 11, an expansion unit 12, an optical splitter 13, a target cable 14, at least one remote unit 15, and at least one optical network unit 16, wherein: The expansion unit 12 and the optical splitter 13 are located in the same target module 11.

[0021] In this embodiment of the utility model, the extension unit 12 belongs to the wireless communication part and is usually used to extend the baseband signal coverage. It is responsible for receiving signals from the baseband processing unit (BBU) and distributing them to multiple remote units. The optical branching device (OBD) 13 belongs to the wired optical access part and is a passive optical device. It is responsible for distributing optical signals from the optical line terminal to multiple optical network units. The target module 11 (i.e., the extension unit of the fused optical branching device, i.e., the fused device) refers to the hardware module that integrates the two functional modules, the extension unit 12 and the optical branching device 13, into one device. It integrates the extension unit of the original extended pico base station and the passive optical branching device of the FTTH network into one fused device. In order to simplify the processing and achieve rapid deployment, a light fusion method is adopted, which only performs structural fusion and does not perform service data processing fusion.

[0022] It should be noted that integrating the expansion unit 12 and the optical splitter 13 into the same target module simplifies the equipment structure, avoids the repetitive work of space occupation, installation and debugging caused by installing two independent devices separately, reduces deployment complexity, and improves deployment speed.

[0023] The target module 11 is connected to at least one remote unit 15 and at least one optical network unit 16 via the target cable 14.

[0024] In this embodiment of the utility model, the target cable 14 is a fused cable formed by fusing two types of cables; The target module 11 connects two types of terminal devices simultaneously via a single target cable 14 (converged cable): a remote unit 15 and an optical network unit 16. The remote unit 15 is on the wireless side, responsible for receiving signals sent by the extension unit and transmitting them via radio frequency. The optical network unit 16 is on the wired side, responsible for receiving optical signals distributed by the optical splitter 13 and converting them into electrical signals for user use. In this way, by deploying only a single converged cable, the extension unit 12 and the optical splitter 13 in the target module 11 can be connected to the remote unit 15 and the optical network unit 16 respectively, instead of deploying a cable between the extension unit 12 and the remote unit 15 and another cable between the optical splitter 13 and the optical network unit 16 as in related technologies. This facilitates cabling and reduces the amount of construction work.

[0025] The fusion device provided in this embodiment integrates the expansion unit and the optical splitter into the same target module. This target module can be connected to the remote unit and the optical network unit through a single cable, namely the target cable. This allows for the deployment of both wireless and wired networks in scenarios requiring simultaneous deployment, with only one planning and one site visit required. This is unlike related technologies which require two sets of equipment, two planning and construction schemes, and two site visits for the deployment of wireless and wired networks. As a result, the deployment process is simplified, deployment efficiency is improved, and deployment costs are reduced.

[0026] This utility model embodiment provides yet another fusion device, referring to... Figure 2 As shown, the fusion device 2 includes a target module 21, an expansion unit 22, an optical splitter 23, a target cable 24, at least one remote unit 25, at least one optical network unit 26, and multiple access points 27, wherein: The expansion unit 22 and the optical splitter 23 are disposed in the same target module 21; Extension unit 22 is connected to at least one remote unit 25 via target cable 24; The optical splitter 23 is connected to at least one optical network unit 26 via the target cable 24.

[0027] Multiple access points 27 are set on the target cable 24.

[0028] Each remote unit 25 is connected to the target cable 24 via an access point 27; Each optical network unit 26 is connected to the target cable 24 via an access point 27.

[0029] In this embodiment of the invention, an access point (i.e., a snap-in point) refers to a pre-set physical interface location on the target cable 24, specifically a physical interface location on the target cable 24 used to connect to a remote unit 25 or an optical network unit 26. Multiple access points 27 are provided on the target cable 24, and these access points 27 are distributed at different locations on the target cable 24. Each access point is used to connect to a remote unit 25 or an optical network unit 26. These access points can be pre-fabricated interfaces or interfaces that can be snapped in on-site, facilitating construction and maintenance. Each remote unit 25 is connected to the target cable 24 through an independent access point and receives signals from the extension unit 22. Similarly, each optical network unit 26 is connected to the target cable 24 through an independent access point and receives optical signals from the optical splitter 23. In this way, each remote unit 25 and each optical network unit 26 are connected through independent access points without interfering with each other. This not only facilitates maintenance and expansion but also improves connection stability and signal quality. At the same time, each access point corresponds to a terminal device (i.e., one remote unit 25 or one optical network unit 26), supporting flexible deployment and future expansion by setting multiple access points on the target cable. This facilitates multi-terminal access, improves cabling efficiency, and enhances system scalability.

[0030] It should be noted that this module describes a highly integrated, cable-converged, and flexible access point deployment scheme. Through a single target cable and multiple access points, it achieves efficient connection between the extension unit 22 and the remote unit 25, as well as between the optical splitter 23 and the optical network unit 26. It is suitable for scenarios that require simultaneous deployment of wireless and wired networks and has the advantages of fast deployment, low cost, and strong scalability.

[0031] The target module 21 described above also includes a first interface 211 and a second interface 212; The expansion unit 22 is connected to the baseband processing unit 28 through the first interface 211; The optical splitter 23 is connected to the optical line terminal 29 via the second interface 212.

[0032] In this embodiment of the present invention, the first interface 211 (i.e., the wireless network uplink interface) is a dedicated uplink interface of the expansion unit in the target module 21. It is usually an optical interface (such as the Common Public Radio Interface, CPRI) used to transmit baseband data. The first interface ensures a high-speed, low-latency connection between the expansion unit and the picocell host and is the starting point of the entire wireless signal transmission. The baseband processing unit is a device responsible for processing baseband signals and is usually connected to the expansion unit 22. It is used to perform signal modulation, demodulation, encoding and other functions. The second interface 212 is a dedicated uplink interface of the optical splitter in the target module 21. It is an optical interface used to receive downlink optical signals from the optical line terminal and transmit the user's uplink optical signals back to the optical line terminal. The second interface 212 is the source of fiber-to-the-home network signals. The optical line terminal is a device located at the network center and is used to send optical signals to the optical network unit and receive the data returned by it. It plays a core role in the passive optical network.

[0033] In this embodiment of the utility model, reference is made to Figure 3 As shown, although the expansion unit 22 and the optical splitter 23 are integrated into a target module 21, the original uplink external interfaces (i.e., the first interface and the second interface) of the expansion unit 22 and the optical splitter 23 remain unchanged. Specifically, the expansion unit 22 is connected to the baseband processing unit through the first interface 211, and the optical splitter 23 is connected to the optical line terminal through the second interface 212. This can achieve the following: (1) Independent interfaces and service isolation: Although the expansion unit and the optical splitter are physically integrated, their uplink interfaces remain independent. This means that the wireless signal and the wired signal are separated from the source and do not interfere with each other, ensuring the performance and stability of their respective networks. This is a lightweight integration strategy that reduces technical complexity; (2) Compatibility with existing networks: The baseband processing unit and the optical line terminal are standard devices in existing mature networks. By retaining independent standardized interfaces, the target module can be seamlessly connected to the operator's existing wireless and wired networks without any modification to the existing core network, which greatly improves the convenience and feasibility of deployment. (3) Simplified site-side deployment: Although the uplink requires two optical fibers (to the baseband processing unit and the optical line terminal respectively), the biggest simplification occurs on the site side. Only one fusion device (i.e. the target device) needs to be installed and one fusion cable (i.e. the target cable) needs to be laid, which solves the needs of wireless and wired coverage at the same time, saving space and construction costs.

[0034] The target module 21 mentioned above also includes a third interface 213, and the expansion unit 22 and the optical splitter 23 are respectively connected to the target cable 24 through the third interface 213.

[0035] In this embodiment of the invention, the third interface 213 is a downlink interface on the target module 21, serving as the output for connecting the target cable 24 (i.e., the fusion cable). It serves both the expansion unit 22 and the optical splitter 23. Specifically, the expansion unit 22 has its corresponding third interface, and the optical splitter 23 also has its corresponding third interface. The number of third interfaces is equal to the sum of the number of third interfaces corresponding to the expansion unit 22 and the optical splitter 23. The connection of the third interface 213 to the target cable 24 means that the expansion unit 22 needs to send data to the remote unit... The electrical / optical signals of element 25 and the optical signals to be distributed by optical splitter 23 to optical network unit 26 are transmitted over long distances through third interface 213 into a target cable 24. This achieves the following: (1) True one-line connection: The third interface is the physical basis for realizing "simultaneous transmission of wireless and wired signals through one cable". It connects multiple independent third interfaces (downlink optical port of expansion unit 22, power output port and downlink optical port of optical splitter 23) to the target cable, so that only one cable needs to be laid externally, which greatly simplifies the wiring complexity. (2) Simplified construction and maintenance: For installers, only one downlink cable needs to be connected, which reduces the difficulty of operation, reduces the probability of error, and also facilitates later maintenance and fault location.

[0036] In this embodiment of the utility model, reference is made to Figure 3 As shown, the expansion unit 22 is connected to the target cable 24 via the third interface 213, and is also connected to the remote unit 25 via the target cable 24; the optical splitter 23 is connected to the target cable 24 via the third interface 213, and is also connected to the optical network unit 26 via the target cable 24, and, referring to... Figure 3 As shown, the number of third interfaces 213 connecting the expansion unit 22 to the remote unit 25 and the number of third interfaces 213 connecting the optical splitter to the optical network unit 26 can be selected according to the actual converged deployment requirements. That is, if the expansion unit 32 connects to two remote units 25, then two third interfaces are set. At the same time, if the optical splitter 33 connects to two optical network units 26, then two more third interfaces are set. Then, all the third interfaces are connected to the same target cable. In this way, multiple downlink interfaces of the expansion unit and the optical splitter are connected to a single target cable through multiple third interfaces, which simplifies the internal wiring structure and enhances the module integration.

[0037] The fusion device provided in this embodiment integrates the expansion unit and the optical splitter into the same target module. This target module can be connected to the remote unit and the optical network unit through a single cable, namely the target cable. This allows for the deployment of both wireless and wired networks in scenarios requiring simultaneous deployment, with only one planning and one site visit required. This is unlike related technologies which require two sets of equipment, two planning and construction schemes, and two site visits for the deployment of wireless and wired networks. As a result, the deployment process is simplified, deployment efficiency is improved, and deployment costs are reduced.

[0038] This utility model embodiment provides another fusion device, see reference. Figure 4 As shown, the fusion device 3 includes a target module 31, an expansion unit 32, an optical splitter 33, a target cable 34, at least one remote unit 35, at least one optical network unit 36, multiple access points 37, and an optical cable junction box 38, wherein: The expansion unit 32 and the optical splitter 33 are disposed in the same target module 31; The target cable 34 also includes a first-class cable 341 and a second-class cable 342; Extension unit 32 is connected to at least one remote unit 35 via a first type cable 341; The optical splitter 33 is connected to at least one optical network unit 36 ​​via a Type II cable 342.

[0039] Among them, the first type of cable 341 is an optical-electric composite cable, and the second type of cable 342 is an easy-to-split optical cable.

[0040] In this embodiment of the invention, the first type of cable 341 is an optoelectronic composite cable, which is made of a composite cable and contains both optical fiber and copper conductors. The optical fiber is used to transmit baseband data light from the extension unit to the remote unit, and the copper conductor is used to provide remote power to the remote unit. Its characteristic is that a single cable solves both signal transmission and power supply problems. The second type of cable 342 is an easy-to-split optical cable, which is made of pure optical fiber cable, but has a special structure, usually a ribbon optical cable or a structure that can be easily stripped and branched. Its function is to transmit optical signals distributed by the optical splitter to various optical network units. Its characteristic is that it is easy to split, which means that during construction, an optical fiber can be easily split at any point without special tools without affecting the main transmission, making it very suitable for flexible cabling from the building junction box to each household in fiber-to-the-home scenarios.

[0041] In this embodiment of the utility model, the first type of cable 341 can specifically be an optoelectronic composite cable, which is the "dedicated highway" for wireless signals and is responsible for connecting the remote unit 25 and supplying it with power; the second type of cable 342 can specifically be an easy-to-connect optical cable, which is the "dedicated highway" for wired signals and is responsible for flexibly connecting the optical network units 26 of each household. By using different types of target cables (i.e., the first type of cable and the second type of cable) to connect the extension unit and the remote unit, and the optical splitter and the optical network unit respectively, the following can be achieved: (1) Professional division of labor and optimal performance: the most suitable cable is tailored for the two different services of wireless and wired, rather than using one type of cable to barely cope with all scenarios; (2) the optoelectronic composite cable meets the remote power supply requirements of the remote unit 35, and the easy-to-connect optical cable perfectly meets the requirements of flexible splitting of optical fiber to the home; (3) physical isolation and no interference: although the two cables may be in the same outer sheath (i.e., "target cable"), the wireless signal (including power) and the wired optical signal are physically separated, completely eliminating interference. The electromagnetic interference or signal crosstalk between each other ensures the transmission quality and network stability of each; (4) Clear construction and maintenance: maintenance personnel can quickly determine the purpose of the cable based on the cable type: the cable with both electricity and fiber goes to the remote unit 35, and the cable with pure fiber goes to the user optical network unit 36, which facilitates fault location and subsequent network expansion; (5) Realize true "integrated deployment": integrating these two cables with different functions into the outer sheath of a single target cable realizes the original intention of "one deployment, dual network coverage". Moreover, when laying, only one thick cable is needed, which is equivalent to laying all the downlink lines of the wireless system and the wired system at the same time, greatly saving manpower and pipeline space.

[0042] The multiple access points 37 also include a first type access point 371 and a second type access point 372; Each remote unit 35 is connected to a type 1 cable 341 via a type 1 access point 371; Each optical network unit 36 ​​is connected to a type 2 cable 341 via a type 2 access point 372.

[0043] In this embodiment of the invention, the first type of access point 371 refers to the access point set on the first type of cable (optical-electric composite cable) 341. It is an access point designed for connecting the remote unit 35. This access point needs to be able to handle both optical fibers and cables simultaneously, completing both optical fiber splicing / termination and power line connection. The second type of access point 372 is an access point set on the second type of cable (easy-to-split optical cable) 342. It is an access point designed for connecting optical network units. This access point is usually a pure optical fiber operation point. Utilizing the characteristics of the easy-to-split optical cable, a single optical fiber can be quickly and with low loss.

[0044] In this embodiment of the utility model, each remote unit 35 has a dedicated access point on the optical-electric composite cable. At this access point, the construction personnel connect one of the optical-electric composite cables to the remote unit. Each optical network unit 36 ​​has a dedicated access point on the easy-to-connect optical cable. At this access point, the construction personnel branch off an optical fiber from the easy-to-connect optical cable and connect it to the optical network unit 36 ​​in the user's home. This achieves the following: (1) By defining two types of dedicated access points, the construction standard is enforced, and the construction personnel will not get confused and will not mistakenly connect the optical network unit 36 ​​to the optical-electric composite cable, nor will they connect the remote unit 35 to the easy-to-connect optical cable, thus ensuring the correctness and security of the network. (2) Flexible on-demand deployment: Access points are pre-planned but activated on demand. Cables can be laid out at once, with multiple access points reserved on them. Later, based on user occupancy or coverage needs, remote unit 35 or optical network unit 36 ​​can be activated at the corresponding access points at any time without rewiring, greatly improving deployment flexibility and reducing initial investment; (3) Fault isolation and easy maintenance: Each terminal device has its own independent physical access point. If one access point or one terminal device fails, it will not affect the normal operation of other access points and other devices on the cable, making it easy to locate and repair faults; (4) Maximize cable capacity utilization: Multiple access points can be densely set on one converged cable, and one cable can serve all wireless and wired users in an area (such as a building), achieving extremely high deployment density and resource utilization.

[0045] The aforementioned fusion device 3 also includes an optical cable junction box 38, and an optical cable junction box 38 is provided at each second type access point 372; In this embodiment of the utility model, the optical cable junction box 38 is a device used to fix and protect the optical cable connection port. It is usually set at the access point. By setting the optical cable junction box 38 at the second type of access point 372, standardized access management of the optical network unit is realized, and the reliability and maintenance convenience of the optical fiber connection are improved.

[0046] Each optical cable junction box 38 is connected to an optical network unit 36.

[0047] It should be noted that when extended pico base stations and fiber-to-the-home networks are deployed independently, as in related technologies, refer to... Figure 5 As shown, the expansion unit 32 and the remote unit 35 are connected by a point-to-point optical fiber composite cable; the optical splitter 33 is connected to 8 rooms (such as...) Figure 5The optical network units 36 shown in ① to ⑧ are connected by easy-to-split optical cables. A splice point is set up in each room, and one optical fiber is laid out through an optical cable junction box so that the optical network unit 36 ​​in the room can be connected later when needed. However, this construction mode requires two sets of equipment (expansion unit 32 + optical splitter 33), two planning and construction schemes (one planning for the extended pico base station, and one planning for the fiber-to-the-home network), and two site visits, involving high engineering construction costs; while referring to Figure 6 The deployment method of this utility model shown is similar to that of... Figure 5 The deployment methods shown are different. Specifically, after integrating the expansion unit 32 of the extended pico base station and the optical splitter 33 of the fiber-to-the-home network into the target module 31, the original two-stage equipment installation is simplified to a single installation. Simultaneously, the original fiber-optic composite cable between the expansion unit 32 and the remote unit 35, as well as the easy-to-connect optical cable between the optical splitter 33 and the optical network unit 36, can also be integrated into a single cable (i.e., the target cable); 8 rooms (e.g.) Figure 6 As shown in ① to ⑧), the fiber optic cable is still laid out by pulling the core through the optical cable junction box at the splice point in each room. The optical network unit 36 ​​in each room is connected to the optical cable junction box. The connection of the remote unit 35 is also made by connecting it from the splice point of the target cable at a suitable location. However, the splice is made of optical-electric composite cable. In this way, in actual construction, only one planning and one site visit are needed to complete the engineering cabling of the remote unit 35 and the optical network unit 36, which simplifies the installation process and reduces the construction cost.

[0048] The target module 31 also includes a first interface 311, a second interface 312, and a third interface 313; The expansion unit 32 is connected to the baseband processing unit 39 through the first interface 311; The optical splitter 33 is connected to the optical line terminal 310 via the second interface 312; The expansion unit 32 and the optical splitter 33 are respectively connected to the target cable 34 through the third interface 313.

[0049] It should be noted that this utility model integrates wireless and wired devices, and the cable architecture between the new form extension unit 32 and the remote unit 35, and between the optical splitter 33 and the optical network unit 36, integrates the access capabilities of optoelectronic hybrid cables and easy-to-connect optical cables, so as to realize the simultaneous entry, design and construction of wireless and wired networks, thereby reducing the construction cost of dual-network projects of wireless and wired networks.

[0050] It should be noted that the converged deployment architecture of the picocell host and fiber-to-the-home network is as follows: Figure 7As shown, the expansion unit and optical splitter are integrated into the target module, and the first and second type cables are integrated into the target cable. In this way, when building a dual network of wireless and wired networks, only one equipment installation is required to meet the dual network requirements. At the same time, during network cabling, the hybrid optical-electrical cable between the expansion unit and the optical splitter and the easy-to-connect optical cable between the optical splitter and the optical network unit are integrated. During indoor cabling, only one cabling is required to meet the access requirements of both remote units and optical network units.

[0051] The fusion device provided in this embodiment integrates the expansion unit and the optical splitter into the same target module. This target module can be connected to the remote unit and the optical network unit through a single cable, namely the target cable. This allows for the deployment of both wireless and wired networks in scenarios requiring simultaneous deployment, with only one planning and one site visit required. This is unlike related technologies which require two sets of equipment, two planning and construction schemes, and two site visits for the deployment of wireless and wired networks. As a result, the deployment process is simplified, deployment efficiency is improved, and deployment costs are reduced.

[0052] In the embodiments provided by this utility model, the structural embodiments described above are merely illustrative. For example, the division of modules is only a logical functional division, and in actual implementation, there may be other division methods, such as: multiple modules or components can be combined, or integrated into another system, or some features can be ignored or not executed. In addition, the various components shown or discussed are coupled to each other or directly coupled.

[0053] The features disclosed in the several method or structural embodiments provided by this utility model can be arbitrarily combined without conflict to obtain new method or structural embodiments.
