Fiber pigtails are classified into single-mode and multimode fiber pigtails and are used for short-
distance connections.

Single-mode fibers have a diameter of 5-10 um and transmit laser light in one mode with
a specified wavelength. These fibers support a wide frequency band and a high transmission
capacity, so they are used for long-distance transmission. Most single-mode fibers are
yellow, as shown in Figure
Multimode fibers have a diameter of 50 um or 62.5 um and transmit laser light in multiple
modes with a specified wavelength. These fibers have a lower transmission capacity than
single-mode fibers and are used for short-distance transmission. Model dispersion occurs
during transmission over multimode fibers. Most multimode fibers are orange, as shown
in Figure 3-4.
