FEC — read before installing: RS-FEC runs inside this module. Leave host FEC off or on auto — do not force RS-FEC on the switch port; enabling host FEC will bring the link down. The far end of the link must also be a single-lambda optic of the same type with onboard FEC.

Compatibility: Compatible with Arista platforms — accepted in 100G QSFP28 ports on the 7020R Series, 7050X3 Series, 7060X Series, 7060X4 Series, 720XP Series, 7280R3 Series, 7300X3 Series, and 7800R3 Series.
