Which choice below does NOT accurately describe the difference between multi-mode and singlemode fiber optic cabling?
A.
Multi-mode fiber propagates light waves through many paths, single-mode fiber propagates a
single light ray only.
B.
Both types have a longer allowable maximum transmission distance than UTP Cat 5.
C.
Multi-mode fiber has a longer allowable maximum transmission distance than single-mode fiber.
D.
Single-mode fiber has a longer allowable maximum transmission distance than multi-mode fiber.
Explanation:
Multi-mode fiber has a shorter allowable maximum transmission distance than single-mode fiber
(2km vs. 10km). Multi-mode transmits the light through several different paths in the cable, whereas
single-mode uses one light path, making single mode perform better. However, multi-mode is less
expensive to install and is used more often in short-to-medium haul networks. Category 5
unshielded twisted pair (UTP) has a maximum transmission distance of 100 meters. Sources: Catalyst
