10GBase-SR is a 10 Gigabit Ethernet standard that uses which type of fiber?

Explanation:
10GBase-SR is about Ethernet over multimode fiber for short distances. The SR designation means short-range, and it uses multimode fiber with an 850 nm optical signal (typically from a VCSEL transmitter). This combination is optimized for shorter links inside data centers, with distances limited by the fiber type (OM1/OM2/OM3/OM4 varieties). It is not designed for single-mode fiber, copper, or wireless—those would be different standards (longer-range single-mode variants, copper Ethernet like 10GBASE-T, or wireless standards). So the correct idea is that 10GBase-SR uses multimode fiber.
