3.3.5. FEC Options

The GTS PMA/FEC Direct PHY Intel FPGA IP supports various FEC modes. You can enable this functionality in the parameter editor by selecting the Enable FEC option in the FEC Options tab. If Enable FEC is off, then FEC Mode option is grayed out in the GUI.

The GTS PMA/FEC Direct PHY Intel FPGA IP supports the following FEC modes:

  • IEEE 802.3 Firecode (2112, 2080) (CL74)
  • IEEE 802.3 RS (528, 514) (CL 91)
  • IEEE 802.3 RS (528, 514) (CL 91) ETC
  • Fibre Channel RS (528, 514)
  • OTU25u RS (528, 514)
