Why each option
Both 10GBase-SR and 10GBase-LR are fiber optic 10 Gigabit Ethernet standards that require fiber cable for data transmission.
10GBase-SR uses multimode fiber, while 10GBase-LR uses single-mode fiber, so they do not both use the single-mode fiber type.
Both standards are based on fiber optics and do not use Unshielded Twisted Pair (UTP) copper cable media for transmission.
Both 10GBase-SR (Short Reach) and 10GBase-LR (Long Reach) are specifications for 10 Gigabit Ethernet over fiber optic cabling, thus they both require fiber cable media for transmission.
10GBase-SR uses multimode fiber, but 10GBase-LR uses single-mode fiber, so they do not both use the multimode fiber type.
