2.2.6. Network Interface
The Intel® FPGA PAC N3000-N has two Quad Small Form-Factor Pluggable (QSFP) 28 cages on the faceplate panel.
- 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
The Intel® FPGA PAC N3000-N supports Short Reach (SR) optical transceivers and Direct Attached Copper (DAC) cables up to 3m in length. QSFP modules must consume no more than 3.5 watts. The table below lists Ethernet cables, QSFP modules and Ethernet switches known to work with the Intel® FPGA PAC N3000-N. Solution providers must validate Ethernet connectivity for the application.
