Which choice below does NOT accurately describe the difference
between multi-mode and single-mode 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 5000 Series Installation Guide
