N10-005 · Question #910

Which of the following is MOST commonly used with a fiber-optic network backbone?

The correct answer is A. 100BaseFX. 100BaseFX is the Fast Ethernet standard specifically designed for fiber-optic cabling, operating at 100 Mbps over multimode fiber. The 'FX' suffix indicates fiber. 100BaseT and 100BaseTX both use copper twisted-pair cabling (the 'T' and 'TX' suffixes indicate twisted pair)…

Explanation

100BaseFX is the Fast Ethernet standard specifically designed for fiber-optic cabling, operating at 100 Mbps over multimode fiber. The 'FX' suffix indicates fiber. 100BaseT and 100BaseTX both use copper twisted-pair cabling (the 'T' and 'TX' suffixes indicate twisted pair). 1000BaseCX uses short-haul copper twinaxial cable (the 'CX' indicates copper), making it unsuitable for fiber backbone runs.
