Description

Technical Field

[0001] The present application relates to the technical field of optical fiber network units, and in particular to a panel-type gateway with an external optical fiber interface. Background Art

[0002] With the recent rise in FTTR and POL solutions, the goal is to create all-optical indoor Wi-Fi solutions, extending fiber to every room and achieving whole-home gigabit Wi-Fi coverage. The original FTTH home single ONU device has been expanded to multiple distributed devices within the room, requiring smaller devices and more invisible installation.

[0003] For example, panel-mounted ONUs installed in 86-inch backplanes and ceiling-mounted optical APs are popular with users for their small footprint and minimal use of indoor space. Furthermore, for aesthetic reasons, optical fiber, power cables, and other wiring are typically routed to the back of the equipment. These flexible wiring harnesses must be connected within the confined space of the 86-inch backplane, leading to issues such as interference between the connector and the backplane, a small bend radius, and stress on the connector.

[0004] For example, the side length of an 86-inch backplane is approximately 60 to 70 mm, while the length of an SC fiber plug is approximately 40 to 60 mm. The bending space for the external fiber is approximately 10 to 20 mm, which can cause interference between the fiber and the 86-inch backplane after insertion. Furthermore, when the fiber is bent within this confined space, the coil radius cannot meet the fiber specifications, which can easily lead to problems such as reduced optical power, increased dispersion, spectral anomalies, and optical axis eccentricity caused by optical port stress.

[0038] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] The embodiment of the present application provides a panel-type gateway with an external optical fiber interface, which can solve the problems in the related art of interference between the optical fiber plug connected to the panel-type ONU and the base box, small bending radius, and plug stress.

[0040] See also Figures 1 to 4 As shown, the embodiment of the present application provides a panel-type gateway with an external optical fiber interface, including:

[0041] The housing includes a bottom shell 3 with an open end and an end cap. The bottom shell 3 and the end cap interlock to form a receiving space for mounting a circuit board. The interlocking connection between the bottom shell 3 and the end cap facilitates installation and removal of the bottom shell 3 and the end cap, and facilitates assembly of the circuit board into the receiving space formed by the interlocking connection between the bottom shell 3 and the end cap.

[0042] The circuit board is located within the housing formed by the interlocking bottom housing 3 and the end cap. The external interface includes a wiring harness 602, one end of which is connected to the circuit board, and a fiber optic interface 601, located outside the housing and connected to the other end of the wiring harness 602. The fiber optic interface 601 is used to connect and remove the pigtail plug. The wiring harness 602 transmits the optical signal received by the fiber optic interface 601 to the circuit board.

[0043] The optical fiber interface 601 provides the transmission channel function of the optical fiber signal, includes the necessary external optical fiber plug adapter, optical signal transmission and other components, is coupled with the optical fiber as one, and provides the docking and adaptation function of the optical fiber plug to the outside.

[0044] In the panel-type gateway with an external fiber optic interface of the present embodiment, the external interface's wiring harness 602 is connected to the circuit board within the housing, and then the fiber optic interface 601 is extended outside the housing. Wiring harness 602 not only transmits optical signals between the circuit board and the fiber optic interface 601, but also, by virtue of its bendability, allows the fiber optic interface 601 to be positioned and angled freely outside the housing.

[0045] When the fiber optic plug is connected to the fiber optic interface 601, the fiber optic interface 601, located outside the housing, can be flexibly positioned anywhere within the 86-inch housing via the wiring harness 602, allowing for more flexible placement of the fiber optic plug. This allows for full utilization of the 86-inch housing space, meeting both the required space for fiber optic plug insertion and the fiber pigtail winding requirements. This eliminates the issues of interference between the fiber optic plug and the 86-inch housing, as well as excessive bending of the fiber pigtail, caused by the fixed position of the fiber optic interface 601.

[0046] In some alternative embodiments: See Figures 4 to 6 As shown, an embodiment of the present application provides a panel-type gateway with an external optical fiber interface. The external interface of the panel-type gateway also includes a BOSA optical module 603 connected to the circuit board. The wiring harness 602 is a flexible wiring harness and one end extends into the housing and is connected to the BOSA optical module 603.

[0047] The BOSA optical module 603 includes a fiber optic adapter (not shown in the figure) for connecting an optical fiber, and the wiring harness 602 includes an optical fiber (not shown in the figure) connected between the fiber optic adapter and the fiber optic interface 601; a first fiber optic ferrule (not shown in the figure) connected to one end of the optical fiber is installed in the fiber optic adapter, and a second fiber optic ferrule (not shown in the figure) connected to the other end of the optical fiber is installed in the fiber optic interface 601.

[0048] The first optical fiber ferrule and the second optical fiber ferrule are both optical fibers wrapped by ceramics. The first optical fiber ferrule and the second optical fiber ferrule are coupled with the optical fibers in the wiring harness 602 to realize emission or input of optical signals.

[0049] BOSA (Bidirectional Optical Assembly) is the abbreviation of a single-fiber bidirectional optical device, which realizes the function of simultaneously receiving and transmitting optical signals on one optical fiber. The optical fiber interface 601 is used to adapt to optical fiber plugs including but not limited to conventional optical fiber plugs that can only transmit optical signals (such as FC type plugs, LC type plugs), and optoelectronic composite cable plugs that can transmit both optical signals and electrical energy (such as SC type plugs, XC type plugs). The optical fiber interface 601 of the embodiment of the present application can be matched with any of the above types of optical fiber plugs.

[0050] The harness 602 is a flexible harness, and the length of the harness 602 can be set specifically according to needs. It includes various single-mode optical fibers of different specifications, and the outer periphery of the optical fibers can have a protective layer of various protective materials, shapes, and colors.

[0051] The wiring harness 602 also includes an outer tube sleeve that wraps the optical fiber, and the surfaces of the BOSA optical module 603 and the optical fiber interface 601 are both wrapped with a protective layer. The protective layers of the BOSA optical module 603 and the optical fiber interface 601 are both connected to a protective sleeve wrapped around the end of the wiring harness 602.

[0052] The protective sleeve is connected to the protective layer of the BOSA optical module 603 and the optical fiber interface 601 and is coated on the end of the wire harness 602, thereby protecting the connection between the end of the wire harness 602 and the BOSA optical module 603 and the optical fiber interface 601 from fatigue fracture.

[0053] In some alternative embodiments: See Figures 4 to 6 As shown, the embodiment of the present application provides a panel-type gateway with an external optical fiber interface. The BOSA optical module 603 of the panel-type gateway also includes a power pin (not shown in the figure). The optical fiber interface 601 is provided with a metal electrode (not shown in the figure), and the wiring harness 602 also includes a power line (not shown in the figure) connecting the power pin and the metal electrode.

[0054] The wiring harness 602 of the embodiment of the present application is equipped with a power cord in addition to the use of optical fiber to transmit optical signals. A metal electrode for connecting to the power cord is provided in the optical fiber interface 601, and a power pin for connecting to the power cord is provided in the BOSA optical module 603, thereby enabling the external interface to transmit both optical signals and electrical energy.

[0055] When the above-mentioned external interface is connected to the circuit board of the panel-type gateway, the external interface can be connected to the optoelectronic composite cable through the optical fiber interface 601, without the need to connect an additional power cord to the circuit board separately. After the external interface is connected to the circuit board, it provides power and optical signals at the same time, which simplifies construction difficulty, reduces tooling costs, facilitates maintenance, and greatly reduces the size of internal optical module devices and power circuits.

[0056] When the BOSA optical module 603 of the panel-type gateway is not equipped with a power pin, the optical fiber interface 601 is not equipped with a metal electrode, and the wiring harness 602 is not equipped with a power cord connecting the power pin and the metal electrode, the optical fiber interface 601 cannot be adapted to connect to the optoelectronic composite cable. At this time, a power interface for connecting the power cord needs to be added to the circuit board, and a wiring hole needs to be opened on the bottom shell 3 to expose the power interface and for inserting the power cord.

[0057] The BOSA optical module 603 with an external interface also includes a tube body (not shown in the figure), in which are connected an optical transmitting device (not shown in the figure) for transmitting optical signals, an optical receiving device (not shown in the figure) for receiving optical signals, and an optical fiber adapter (not shown in the figure) for coupling optical fibers.

[0058] The optical emitting device is used to emit an optical signal based on the electrical signal. The tube body is used to achieve a fixed connection between the optical emitting device and the optical fiber adapter. The optical signal is transmitted into the optical fiber adapter by the tube body. A first optical fiber ferrule is installed in the optical fiber adapter. The first optical fiber ferrule is an optical fiber wrapped in ceramic, and the first optical fiber ferrule realizes the emission of the optical signal.

[0059] The BOSA optical module 603 transmits and receives light through the same optical fiber. Therefore, the BOSA optical module 603 also includes an optical receiving device for converting optical signals into electrical signals. The optical signal input into the tube body through the first optical fiber ferrule in the optical fiber adapter is reflected in the tube body to the optical receiving device and converted into an electrical signal by the optical receiving device.

[0060] The tube body allows for the transmission of optical signals converted from electrical signals, which are then emitted by the first optical fiber ferrule. Furthermore, the optical signals transmitted by the first optical fiber ferrule are sent to the optical receiver, where they are converted into electrical signals. To this end, the optical transmitter, receiver, and fiber optic adapter must all be secured to the tube body.

[0061] In some alternative embodiments: See Figure 1 and Figure 2 As shown, an embodiment of the present application provides a panel-type gateway with an external optical fiber interface, and a card column 604 is provided on the outer wall of the optical fiber interface 601 of the panel-type gateway, and a circular card groove 303 and a fan-shaped card groove 305 are provided on the outer wall of the bottom shell 3 to match the card column to fix the optical fiber interface 601 on the outer wall of the bottom shell 3.

[0062] Two latches 604 are spaced apart on the outer wall of the optical fiber interface 601. One latch 604 is pivotally connected to the circular slot 303, while the other is slidably connected to the fan-shaped slot 305. The two latches 604 on the optical fiber interface 601 snap into place with the circular slot 303 and the fan-shaped slot 305, respectively, securing the optical fiber interface 601 to the bottom housing 3. The center of the circular slot 303 is concentric with the center of the fan-shaped slot 305.

[0063] The two clamping posts 604, the circular clamping slot 303, and the fan-shaped clamping slot 305 not only fix the optical fiber interface 601 on the bottom shell 3, but also allow the optical fiber interface 601 to rotate on the bottom shell 3 with the circular clamping slot 303 as the rotation center, and use the fan-shaped clamping slot 305 as a rotation angle limiting mechanism to make the angle of the optical fiber interface 601 on the bottom shell 3 adjustable.

[0064] In some alternative embodiments: See Figures 4 to 8 As shown, an embodiment of the present application provides a panel-type gateway with an external optical fiber interface. The circuit board of the panel-type gateway includes a chip circuit board 4 and a photoelectric board 5 that are stacked on each other. The chip circuit board 4 is connected to a communication network port 401, and the BOSA optical module 603 is located on the photoelectric board 5.

[0065] A connector electrically connected between the chip circuit board 4 and the photovoltaic panel 5 is provided. The chip circuit board 4 and the photovoltaic panel 5 are pluggable and connected to each other via the connector. The connector includes a connector socket 405 fixed to the chip circuit board 4 and a connector plug 501 fixed to the photovoltaic panel 5. The chip circuit board 4 and the photovoltaic panel 5 are electrically connected to each other via the connector socket 405 and the connector plug 501.

[0066] The chip circuit board 4 and the photovoltaic panel 5 are fastened together via a fastening portion. The fastening portion comprises multiple studs 406 fixed to the chip circuit board 4, each having threaded holes. The photovoltaic panel 5 is secured to the studs 406 via screws. The communication network port 401 on the chip circuit board 4 is preferably an RJ45 connector for connecting to a network cable, enabling the panel-type gateway to provide network connectivity for user terminal devices.

[0067] The embodiment of the present application divides the circuit board into a chip circuit board 4 and a photoelectric panel 5 that overlap each other. The photoelectric panel 5 is used to convert external AC or DC power into DC power of its own applicable voltage and to supply power to the chip circuit board 4. The chip circuit board 4 is used to process optical signals. A heat sink 402 is provided on the front of the chip circuit board 4 to cool the chip circuit board 4.

[0068] In some alternative embodiments: See Figures 1 to 8As shown, an embodiment of the present application provides a panel-type gateway with an external optical fiber interface, wherein the chip circuit board 4 of the panel-type gateway is located on the side close to the end cover, the photoelectric panel 5 is located on the side close to the bottom shell 3, and the chip circuit board 4 is connected to a first switch 403 and a second switch 404.

[0069] The end cover is equipped with an interface 203 for connecting to the communication network port 401, a button 201 for pressing the first switch 403, and a through hole for connecting to the second switch 404. The end cover comprises an upper cover 2 and a panel 1. The upper cover 2 is a rectangular structure with one end open. The end face of the upper cover 2 is provided with fixing holes for connecting to the 86-type bottom box. The panel 1 can be removably connected to the end face of the upper cover 2 to conceal the fixing holes. The side walls of the upper cover 2 are provided with upper cover heat dissipation holes 202, and the bottom shell 3 is provided with bottom shell heat dissipation holes 302.

[0070] An opening 304 for leading out the optical fiber interface 601 and the wiring harness 602 is defined on the sidewall of the bottom shell 3. A cover plate 301 is slidably connected to the bottom shell 3 to open or close the opening 304. The cover plate 301 has a notch to allow for the wiring harness 602 to pass through. The diameter of the opening 304 is slightly larger than the cross-section of the optical fiber interface 601, facilitating the passage of the optical fiber interface 601 out of the housing through the opening 304.

[0071] How it works

[0072] An embodiment of the present application provides a panel-type gateway with an external optical fiber interface. Since the panel-type gateway with an external optical fiber interface of the present application is provided with a shell, the shell includes a bottom shell 3 with an opening at one end, and an end cover, the bottom shell 3 and the end cover are buckled together to form a receiving space; a circuit board, the circuit board is located in the receiving space formed by the bottom shell 3 and the end cover being buckled together; the external interface, the external interface includes a wiring harness 602 connected to the circuit board at one end, and a fiber optic interface 601 located outside the shell and connected to the other end of the wiring harness 602.

[0073] Therefore, the panel-type gateway with an external optical fiber interface of the present application uses the wiring harness 602 of the external interface to connect to the circuit board in the housing, and then leads the optical fiber interface 601 to the outside of the housing. The wiring harness 602 can not only transmit optical signals between the circuit board and the optical fiber interface 601, but also utilizes the bendability of the wiring harness 602 itself to freely change the position and angle of the optical fiber interface 601 outside the housing. This makes it easier for the optical fiber interface 601 to plug and unplug the optical fiber plug more flexibly. This makes it easier to fully utilize the space of the 86-inch bottom box to meet the spatial plug-in requirements of the optical fiber plug and the fiber coiling requirements of the pigtail.
