[0002] At present, the single-to-multimode conversion device is mainly composed of some optical component parts and a single-channel conversion unit, and the switching is achieved by plugging and unplugging the external optical cable. The single-to-multimode conversion device is mainly used in application scenarios such as data link shipboard equipment, ground station equipment and data processing centers, which are generally in a hot and humid smoke environment or a dusty environment. The optical components and single-channel conversion units do not have the ability to resist hot and humid smoke and dust. Frequent plugging and unplugging of external optical cables leads to contamination by liquids, salt spray and dust. When the optical transmission components are contaminated by liquids, smoke, dust, etc., the quality of the communication link drops sharply, affecting the system function and performance.

[0028] After completing the connection switching, change the conversion relationship information, end the switching state, and execute the steps of forwarding the cache signal in the single-mode FIFO receiving unit to the corresponding multi-mode FIFO sending unit, and forwarding the cache signal in the multi-mode FIFO receiving unit to the corresponding single-mode FIFO sending unit.

[0029] Furthermore, it also includes a user control unit, which is used to receive conversion relationship information input by a user.

[0030] Further, the user control unit includes a UART unit, a command parsing unit, a register control unit and a register group;

[0053] The embodiments of the present invention provide a single-mode and multi-mode optical terminal switching method, device, equipment and medium, which are suitable for single-mode and multi-mode switching application scenarios, are conducive to achieving lossless switching, and protect optical components from environmental pollution during switching.

[0054] The single-mode and multi-mode optical terminal switching solution proposed by the present invention is composed of hardware and software. Figure 1 , Figure 2 As shown, Figure 1 is a schematic diagram of a single-mode multi-mode optical terminal hardware system according to an embodiment of the present invention. Figure 2 This is a software module diagram of a single-mode and multi-mode optical terminal switching method according to an embodiment of the present invention. The hardware design mainly includes FPGA, single-mode optical module, and multi-mode optical module. The optical signals derived from the single-mode optical module and the multi-mode optical module are connected to the optical connector of the chassis through optical fiber jumpers, and the single-mode optical module and the multi-mode optical module complete the photoelectric signal conversion. A matrix mapping table is built into the FPGA, and the FPGA completes the matrix switching of the electrical signal data according to the matrix mapping table. The built-in matrix mapping table can be manually configured and modified.

[0055] In one implementation, the hardware system provides a user serial port connected to the FPGA, and completes external UART serial port communication through the user serial port to achieve switching control and configuration, reading or modification of the matrix mapping table. The number of single-mode and multi-mode channels of the hardware can be equal or unequal. When data is transparently transmitted, single-mode or multi-mode channels that are not on the matrix mapping table are in an inoperative state.

[0056] In the hardware system, the materials of the optical connector and the chassis shell are made of salt spray-proof materials, such as passivated stainless steel. The PCB circuit board inside the chassis is sprayed with polyurethane varnish, left to solidify under high temperature conditions, and sprayed with multiple layers in sequence to make the PCB circuit board mildew-proof, moisture-proof, and salt spray-proof.

[0057] The software design scheme consists of a single-mode high-speed transceiver, a single-mode FIFO unit, a switching matrix unit, a multi-mode FIFO unit and a multi-mode high-speed transceiver. Among them, the single-mode FIFO unit includes a single-mode FIFO receiving unit and a single-mode FIFO sending unit, and the multi-mode FIFO unit includes a multi-mode FIFO receiving unit and a multi-mode FIFO sending unit. In the software module, a single-mode FIFO unit corresponds to a single-mode high-speed transceiver, and a multi-mode FIFO unit corresponds to a multi-mode high-speed transceiver. In the hardware system, a single-mode high-speed transceiver corresponds to a single-mode optical module, and a multi-mode high-speed transceiver corresponds to a multi-mode optical module. Through the modular design of the software, the number of channels can be customized according to product requirements. It only needs to define the same number of single-mode optical modules, multi-mode optical modules, registers, single-mode FIFO send / receive units and multi-mode FIFO send / receive units, single-mode high-speed port transceivers and single-mode high-speed port transceivers.

[0058] The present invention is based on a software-defined single-mode and multi-mode optical terminal switching method, which specifically includes the following steps.

[0059] S1, receiving a single-mode electrical signal or a multi-mode electrical signal and decoding it;

[0060] S2, buffering the decoded signal of the single-mode electrical signal in the single-mode FIFO receiving unit, and buffering the decoded signal of the multi-mode electrical signal in the multi-mode FIFO receiving unit;

[0061] S3, forwarding the buffered signal in the single-mode FIFO receiving unit to the corresponding multi-mode FIFO sending unit according to the conversion relationship information, and forwarding the buffered signal in the multi-mode FIFO receiving unit to the corresponding single-mode FIFO sending unit;

[0062] S4, after encoding the buffered signal in the multi-mode FIFO sending unit, send it through the multi-mode high-speed transceiver, and after encoding the buffered signal in the single-mode FIFO sending unit, send it through the single-mode high-speed transceiver.

[0063] Among them, after the single-mode high-speed port transceiver receives a single-mode electrical signal, or the multi-mode high-speed port transceiver receives a multi-mode electrical signal, correspondingly, according to the switching relationship, the received single-mode electrical signal needs to be converted into a multi-mode electrical signal and output through a multi-mode optical module, and the received multi-mode electrical signal needs to be converted into a single-mode electrical signal and output through a single-mode optical module. In this solution, the physical optical signal is converted into an electrical signal recognizable by the software system through a hardware optical module, and the converted electrical signal is decoded and processed in the corresponding single-mode high-speed port transceiver or multi-mode high-speed port transceiver, and the decoded single-mode electrical signal is transmitted to the single-mode FIFO receiving unit for data caching, and the decoded multi-mode electrical signal is transmitted to the multi-mode FIFO receiving unit for caching of received data.

[0064] The receiving cache data of the single-mode FIFO receiving unit and the multi-mode FIFO receiving unit are read by the switching matrix unit, and are transmitted to the corresponding multi-mode FIFO sending unit or the single-mode FIFO sending unit for caching the sending data according to the conversion relationship. A matrix mapping table is pre-stored in the switching matrix unit, mapping the corresponding relationship between each single-mode FIFO receiving unit and the multi-mode FIFO sending unit, and the multi-mode FIFO receiving unit and the single-mode FIFO sending unit.

[0065] Among them, the single-mode FIFO receiving unit and the multi-mode FIFO receiving unit are both composed of multiple receiving FIFOs, and the single-mode FIFO sending unit and the multi-mode FIFO sending unit are also respectively composed of multiple sending FIFOs. The number of receiving FIFOs and sending FIFOs is equal. The single-mode FIFO receiving / sending unit and the multi-mode FIFO receiving / sending unit are mainly used to switch the data buffer between the matrix unit and the high-speed port transceiver. The receiving FIFO and sending FIFO of the single-mode FIFO receiving / sending unit and the multi-mode FIFO receiving / sending unit are realized by calling the asynchronous FIFO IP integrated in the FPGA. Figure 3 The figure shows a schematic diagram of the receiving FIFO. The receiving FIFO is cached by writing electrical signal data into the single-mode or multi-mode high-speed port transceiver, and the cached electrical signal data is then read by the switching matrix unit. Figure 4 The figure shows a schematic diagram of a transmit FIFO. The transmit FIFO is cached by writing electrical signal data into the switching matrix unit. The cached electrical signal data is then read by a single-mode high-speed port transceiver or a multi-mode high-speed port transceiver, and the electrical signal is finally sent out.

[0066] Finally, the buffered data of the single-mode FIFO sending unit is encoded and sent by the single-mode high-speed transceiver, and the buffered data of the multi-mode FIFO sending unit is encoded and sent by the multi-mode high-speed transceiver. Figure 5 The figure shows a schematic diagram of a high-speed port transceiver. The single-mode / multi-mode high-speed port transceiver internally calls the serial high-speed transceiver IP integrated in the FPGA to realize the decoding and encoding of the electrical signal. The high-speed port transceiver receives the electrical signal data of the single-mode optical module or the multi-mode optical module, decodes it, and transmits it to the single-mode FIFO receiving unit or the multi-mode FIFO receiving unit. It receives the electrical signal data of the single-mode FIFO sending unit or the multi-mode FIFO sending unit, encodes it, and transmits it to the single-mode optical module or the multi-mode optical module.

[0067] See also Figure 6 In the switching matrix unit software flow chart shown, a specific implementation of step S3 includes: if the conversion relationship information indicates that the current switching state is entered, stop forwarding the cache signal, and connect the single-mode FIFO receiving unit to the corresponding multi-mode FIFO sending unit, and connect the multi-mode FIFO receiving unit to the corresponding single-mode FIFO sending unit according to the matrix mapping table; after completing the connection switching, change the conversion relationship information, end the switching state, and execute the steps of forwarding the cache signal in the single-mode FIFO receiving unit to the corresponding multi-mode FIFO sending unit, and forwarding the cache signal in the multi-mode FIFO receiving unit to the corresponding single-mode FIFO sending unit.

[0068] In the above switching steps, the lossless switching conversion relationship and data forwarding are implemented by FPGA code, and the switching matrix unit executes the lossless switching conversion relationship to forward data between the single-mode FIFO receiving / transmitting unit and the multi-mode FIFO transmitting / receiving unit. The code flow is that when the value of the conversion change effective register is 1, it enters the switching state, stops the forwarding of cached data between the single-mode / multi-mode FIFO units, and avoids data loss due to the switching conversion relationship. According to the matrix mapping table, for the received data is a single-mode electrical signal, the single-mode FIFO receiving unit is connected to the corresponding multi-mode FIFO transmitting unit in the matrix mapping table. For the received data is a multi-mode electrical signal, the multi-mode FIFO receiving unit is connected to the corresponding single-mode FIFO transmitting unit in the matrix mapping table. The single-mode or multi-mode channel not on the matrix mapping table is in an inoperative state. After the switching conversion relationship is completed, the conversion change effective register automatically returns to 0, the switching state ends, and the switching matrix unit restarts the cache data forwarding. If the value of the conversion change effective register is 0, there is no need to switch the connection, and forwarding can be performed according to the current mapping relationship.

[0069] In one embodiment, the default conversion relationship of the switching matrix unit is that the single-mode FIFO receiving unit and the multi-mode FIFO sending unit are connected and switched in sequence one by one, and the multi-mode FIFO receiving unit and the single-mode FIFO sending unit are connected and switched in sequence one by one. Figure 7 The schematic diagram of the default conversion relationship of the switching matrix unit shown in the figure shows that the multiple receiving FIFOs and multiple transmitting FIFOs of the single-mode and multi-mode can be numbered, and the switching conversion is completed in sequence according to the numbers as the default switching order. In addition, the order can also be configured.

[0070] In one embodiment, a user input is provided to input conversion relationship information, and the switching state and matrix mapping table can be edited. Figure 8 The user control unit is shown in the figure. The user control unit consists of four sub-units: UART unit, command parsing unit, register control unit, and register group. The register group consists of multiple registers, and the value of each register constitutes the mapping relationship between the single-mode FIFO unit and the multi-mode FIFO unit. The switching matrix unit performs connection switching according to the value of the register group.

[0071] Specifically, the user inputs the conversion relationship information through the user serial port, and the input data is serial data. The serial data is transmitted to the UART unit, and the serial-to-parallel conversion is performed according to the UART communication protocol. The converted parallel data is parsed by the command parsing unit according to the register read and write command format. If the address, write command, and write data are obtained by parsing, they are output to the register control unit, and the register control unit modifies the corresponding register value in the register group to form an updated matrix mapping table. If the address and read command are obtained by parsing, they are output to the register control unit, and the register control unit reads the corresponding register value in the register group. The register control unit returns the read data to the command parsing unit, and the parallel data is output to the UART unit according to the register read and write command format. The UART unit converts it into parallel data and outputs it to the user interface. Among them, the read and write command format refers to Table 1.

[0072] Table 1 Command format planning reference table.

[0073]

[0074] The address, value meaning and number of channels of the internal registers can be planned and modified according to the actual situation. A planning scheme for a register group can be referred to Table 2.
