Item Single mode fiber Multi-mode fiber
Dispersion Less dispersion
Allows greater dispersion and
therefore, signal loss exists.
Light source and
transmission
distance
Uses lasers as the light
source often within campus
backbones for distance of
several thousand meters
Uses LEDs as the light source
often within LANs or distances
of a couple hundred meters
within a campus network

Fiber connectors are indispensable passive components in an optical
fiber communication system. They allow the removable connection
between optical channels, which makes the optical system debugging
and maintenance more convenient. There are multiple types of fiber
connectors. Figure 27 shows an LC connector.
