Ethernet 100BaseFX networks use what type of cabling?
|
|
Fiber optic
|
|
|
Shielded twisted pair
|
|
|
Coaxial
|
|
|
Unshielded twisted pair

Explanation:
Detailed explanation-1: -100BaseTX requires Category 5 cable, and 100BaseFX uses fiber-optic cable. For more information, see the section “100BaseT4” in this chapter. B, C, D. Fast Ethernet standards are specified in the IEEE 802.3u standard.
Detailed explanation-2: -100BASE-FX is a physical layer specification for Fast Ethernet over fiber optics using two multi-mode fiber optic strands for both links, reception and transmission. The maximum length is 412 meters for half-duplex connections (to ensure that collisions are detected) or 2 kilometers for full-duplex.
