#架构#fpga开发#服务器#人工智能#信号处理
  • 4-channel 10G SFP+ Fiber Optic Channels
  • PCIe x8 Host Interface, supports 5Gbps/lane, system bandwidth 4GByte/s
  • Fiber Optic Channels support RapidIO, Aurora, and other protocol standards, up to 10Gbps/lane
  • Independent DDR3 SDRAM cache, operating clock frequency 500MHz
  • 4-channel SATA 3.0 interface
  • High-performance clock management unit

A 4-channel 10G fiber optic adapter based on a PCI Express bus architecture, the board features four SFP+ 10 Gigabit fiber optic interfaces, an x8 PCIe host interface, and one group of 64-bit DDR3 SDRAM as high-speed cache, enabling high-speed acquisition, real-time recording, and broadband playback of 4-channel fiber optic network data. The board also features four SATA interfaces, enabling high-speed storage of fiber optic data, supporting the SATA 3.0 standard, with a maximum storage bandwidth of up to 1.6 GByte/s. The board is a standard full-height, half-length PCIe form factor, suitable for current mainstream servers or workstations, and can be widely used in data centers, server acceleration computing, and other scenarios. It can also be used in hardware-in-the-loop simulation systems.
