Which type of fiber-optic cabling only allows an individual light path through it?
A) Unicast mode
B) Stream mode
C) Multimode
D) Single-mode
D
Explanation: There are two main types of fiber optic cabling: single-mode and multimode. Single-mode cabling has a very small interfiber core that only allows a single mode (path) of light between the transmitter and the receiver. Multimode cabling has a larger core and allows for multiple modes (paths) of light; this type of cabling is typically used for shorter distances.
