Embodiment 1
[0025] refer to figure 2 . The 6U board can use 3 optical modules to configure the digital signal processor DSP to realize the photoelectric-to-optical conversion of 60 high-speed signals. The 54 optical signals received by the digital signal processor DSP block are converted into 54 channels through the optical module through the backplane, and the high-speed The GTH electrical signal of the transceiver is demodulated, decoded, and de-interleaved through FPGA2, and the processed data is sent to FPGA1 through 12 GTH electrical signals for data modulation, demodulation capture, encoding, and compression of the encoded data stored in the memory , The data processed by FPGA1 is sent to an optical module through 6 GTH electrical signals for electro-optical conversion, and the converted 6 optical signals are sent to the backplane to other boards for subsequent digital signal processing. QDR is mainly used for data encoding and compression, and QDR2 can be a 144Mbit memory.
Embodiment 2
[0027] refer to image 3 . The beam processing module can use 6 optical modules to configure the beam processing module to realize the photoelectric-to-optical conversion of 129 high-speed signals. Among them, the 105 optical signals on the front panel are converted into 105 electrical signals through the optical module, which are respectively sent to FPGA1 65 channels, to FPGA2 has 64 channels, and FPGA1 and FPGA2 perform high-speed data interaction through 12-channel high-speed transceiver GTH, complete real-time beam zeroing of DBF signals, digital beam synthesis DBF weighting, and 24 channels of electrical signals after processing are passed through an optical module. The electro-optical conversion is converted into optical signals and sent to the backplane to other boards for subsequent digital signal processing.
Embodiment 3
[0029] refer to Figure 4 . The 6U board can use 4 optical modules to configure a high-speed photoelectric conversion module to realize the photoelectric-to-electrical conversion of 76 high-speed signals. The 12 optical signals on the front panel and the 64 optical signals on the back panel are converted into 76 electrical signals through the photoelectric conversion module. 64 channels of FPGA2 and 12 channels of FPGA1, data interaction and routing between FPGA1 and FPGA2 through the 12-channel high-speed transceiver GTH, and then the routed data is sent to the Four optical modules are used for electro-optical conversion, and the converted 76 optical signals are sent to 64 channels on the backplane and 12 channels on the front panel, which can realize high-speed exchange of 78 optical signals. The 6U board uses an Ethernet switch chip to realize data exchange with Ethernet. The SOC connects 1 PHY to the switch chip to manage the Ethernet switch chip, and connects 1 PHY to SG...
