Which Ethernet naming defines Gigabit Ethernet over multimode fiber?

In Ethernet naming, the number after BASE tells you the speed, and the suffix describes the media and wavelength used. For Gigabit Ethernet over fiber, the SX suffix indicates short-wavelength transmission over multimode fiber. This setup uses 850 nm light and is optimized for multimode fiber types commonly used inside buildings and data centers. So the option that specifies Gigabit Ethernet over multimode fiber is the one with 1000BASE-SX, since LX is intended for long-wavelength, typically single-mode fiber and longer distance, while T denotes copper and 10GBASE-SR is a higher-speed standard over multimode.
