Intel® gigabit fiber adapters support IEEE standards 1000BASE-SX and 1000BASE-LX. These standards define a speed of 1000mbps. There is no support for lower speeds.
In comparison, the 1000BASE-T standard for gigabit copper adapters supports automatic negotiation of 10, 100, 1000 mbps. Autonegotiation is required by the standard.
