2.2.6. Network Interface

The Intel® FPGA PAC N3000 has two Quad Small Form-Factor Pluggable (QSFP) 28 cages on the faceplate panel. The supported network interfaces are based on the board ordering part number (OPN). There are two OPNs for the board. One OPN supports 10GbE and the other supports 25GbE.

25GbE network configurations:
  • 2 x 25 GbE per QSFP28
  • 4 X 25 GbE on QSFP A, QSFP B is disabled
  • Programmable Forward Error Correction (FEC) including Reed-Solomon Forward Error Correction (RS-FEC), BASE-R FEC (also known as Firecode) and no FEC
    Note: Support is provided for IEEE 802.3 clause 108 and clause 74. Clause 91 is not supported.
  • Supports 25GBASE-CR and 25GBASE-SR
10GbE network configurations:
  • 4 x 10GbE per QSFP+
  • Supports 10GBASE-CR and 10GBASE-R
Ethernet functionality for both 10 GbE and 25 GbE network configurations:
  • User configurable pause flow frame generation
  • User configurable maximum packet size up to 9600 bytes
  • Auto negotiation is not implemented in Intel provided FPGA image

The Intel® FPGA PAC N3000 supports Short Reach (SR) optical transceivers and Direct Attached Copper (DAC) cables up to 3m in length. The tables below list Ethernet cables, QSFP modules and Ethernet switches known to work with the Intel® FPGA PAC N3000.
