[0045] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] Please refer to Figures 1-6 The present invention discloses a twelve-channel multi-functional optical transceiver, which consists of five parts, as follows: Figure 1As shown, a twelve-channel multi-functional optical transceiver includes a housing 1, a main control module 3, a control component 4, an interface component 5, and a display component 7. The housing 1 has a hollow internal structure, and a power supply unit 2 is installed inside the housing 1. An exhaust vent 11 is provided on the front side wall of the housing 1, and an exhaust fan 12 is installed at the exhaust vent 11. The main control module 3 and the control component 4 are installed inside the housing 1. The interface component 5 is installed on the rear side wall of the housing 1, and two sets of power interfaces 6 are provided on the right side of the interface component 5. The display component 7 is installed on the front side wall of the housing 1, and is located to the right of the exhaust fan 12. The housing 1 of this invention is a standard 1RU width chassis, compact in size, easy to deploy, and flexible in installation. It can achieve multi-point chain transmission via optical fiber and data transmission lines, and long-distance transmission via single-mode optical fiber, making it widely applicable to program production sites and television transmission centers. When using single-mode optical fiber connections, the typical transmission distance is not less than 10 kilometers. In use, connect one end of the power cord to the power interface 6 and the other end to an external AC power source. When multiple devices need to be connected, connect one end of a data transmission cable to the SDI output interface 54 of one device and the other end to the SDI input interface 53 of another device. Then, connect the data transmission cable to the video receiving device and camera via other data transmission cables. The display component 7 can display the signal strength, operating status, and chassis temperature of each channel in real time. Combined with remote monitoring via the UI page, it ensures safe broadcasting. In this embodiment, since the 12G-SDI video output supporting 12 channels of unidirectional loop-out generates a lot of heat, two sets of exhaust fans 12 are set up and powered by two power supplies 41 respectively. This prevents both exhaust fans 12 from stopping when one power supply 41 fails, causing heat accumulation and potentially damaging the equipment.

[0047] In one specific embodiment, the power supply unit 2, the main control module 3, the control component 4, the interface component 5, the power interface 6, the display component 7, and the exhaust fan 12 are electrically connected.

[0048] In a specific embodiment, such as Figure 1 , Figure 2As shown, the main control module 3 includes a motherboard 31, a CPU 33, and an SFP optical module 34. The motherboard 31 is mounted on the bottom surface of the housing 1. An Ethernet interface 32 is located on the lower side of the motherboard 31 and is situated on the right side of the interface assembly 5. The front end of the Ethernet interface protrudes from the rear side wall of the housing 1. The CPU 33 is mounted in a slot on the surface of the motherboard 31, and the SFP optical module 34 is mounted on the upper surface of the motherboard 31. The motherboard 31 and CPU 33 are responsible for controlling the entire device according to the programmed instructions and can make corresponding adjustments based on other commands issued to the device. The device can form two independent Gigabit Ethernet transmissions through the Ethernet interface 32, which conforms to the relevant IEEE 802.3 standards. The SFP optical module 34 is connected to the fiber optic coupler 55 via a fiber optic patch cord. The function of the SFP optical module 34 is to realize the mutual conversion between electrical and optical signals, enabling the network device to perform high-speed, long-distance data transmission through optical fiber.

[0049] In a specific embodiment, such as Figure 1 , Figure 3 As shown, the interface assembly 5 includes a connecting bracket 51, a connecting plate 52, an SDI input interface 53, an SDI output interface 54, and a fiber optic coupler 55. Several connecting brackets 51 are mounted on the bottom surface of the housing 1, and several connecting plates 52 are also mounted on the bottom surface of the housing 1. Each connecting plate 52 corresponds to one of the connecting brackets 51. The upper end of each connecting bracket 51 is fixedly connected to the connecting plate 52 by a pin. Several SDI input interfaces 53 are mounted on the front end of the connecting plate 52, with the front end of each SDI input interface 53 extending through the rear side wall of the housing 1. Several SDI output interfaces 54 are mounted on the front end of the connecting plate 52, with the front end of each SDI input interface 53 extending through the rear side wall of the housing 1. The SDI output interfaces 54 are located below the SDI input interfaces 53. The fiber optic coupler 55 is mounted on the rear side wall of the housing 1, located to the right of the SDI input interfaces 53. The fiber optic coupler 55 is connected to the SFP optical module 34 via a fiber optic patch cord. The connecting plate 52 is connected to the connecting bracket 51 by a pin and fixed to the bottom surface of the housing by bolts. The connecting bracket 51 is electrically connected to the medium-wave splitter 42. The function of the fiber optic coupler 55 is to distribute optical signals to different optical fibers in a specific ratio, or to combine multiple signals into a single optical fiber for transmission.

[0050] In a specific embodiment, such as Figure 3 , Figure 4 As shown, the number of connecting brackets 51, connecting plates 52, SDI input interfaces 53, and SDI output interfaces 54 are all 12. This utility model can simultaneously support the transmission of different types of signals, such as 12 channels of unidirectional 12G-SDI video with loop-out and 2 channels of independent gigabit Ethernet.

[0051] In a specific embodiment, such as Figure 3, Figure 4 As shown, the power supply unit 2 includes an SDI power supply board 21 and a main power supply board 22. The SDI power supply board 21 is mounted on the bottom surface of the housing 1 and is electrically connected to the interface assembly 5. The main power supply board 22 is mounted on the bottom surface of the housing 1 and is located to the right of the SDI power supply board 21. A portion of the control assembly 4 is mounted above the main power supply board 22. The main power supply board 22 supplies power to various electrical appliances. It supplies power to the SDI power supply board 21, which then supplies power to the video receiving device and camera via data transmission lines. By using the main power supply board 22 and the SDI power supply board 21, the current of each electrical appliance can be effectively controlled, preventing damage from excessive current or voltage.

[0052] In a specific embodiment, such as Figure 6 As shown, the control component 4 includes a power supply 41 and a mid-wave optical splitter 42. Two sets of power supplies 41 are installed on the top of the main power supply board 22, each corresponding to a power interface 6. The power supplies 41 are electrically connected to the power interfaces 6. The mid-wave optical splitter 42 is installed on the bottom surface of the housing 1, positioned in front of the SDI power supply board 21. This device supports 12 channels of unidirectional 12G-SDI video output with loopback, requiring significant power; therefore, two sets of power supplies 41 are used. The power supplies 41 convert standard AC power into low-voltage, stable DC power. The mid-wave optical splitter 42 is used to multiplex or demultiplex optical signals of different wavelengths to achieve simultaneous transmission of multiple signals in a single optical fiber. By using an optical fiber coupler 55 and the mid-wave optical splitter 42, signal splitting and wavelength multiplexing are achieved collaboratively. A single fiber can efficiently schedule multiple signals, solving the problem of traditional equipment requiring multiple units to be stacked. This invention employs bidirectional CWDM technology, featuring equalization and clock regeneration, and its technical specifications meet broadcast-grade requirements, passing the Pathological Signal Test.

[0053] In a specific embodiment, such as Figure 5 As shown, the display assembly 7 includes a lamp board adapter board 71 and an OLED display screen 72. The lamp board adapter board 71 is mounted on the front sidewall of the housing 1, and the OLED display screen 72 is embedded in the front sidewall of the housing 1.
