They have small diameter, light weight and installation friendly since they come in a single tube with loose tube fiber count up to 12 fibers. Their compact construction protect the loose tube from shrinking, the armour makes it crush, rodent and impact resistant, the water proofing tape and jelly protects it from water and moisture, the outer PE sheath gives it ultraviolet protection. This cable is suitable for outdoor distribution through ducts, conduits or aerial pipe lines. They come in larger delivery length, so can also be used in long distance communication system, service drop cables, building interconnections.

Optical Characteristics
Of all the differences between multimode & singlemode fiber, the most fundamental differences are the size of the fiber’s core and the associated attenuation or loss and bandwidth of the fiber. The smaller the core diameter, the higher the fiber’s bandwidth and the lower the attenuation (loss in dB per kilometer). The fiber’s attenuation and bandwidth are also dependent on wavelength.
Singlemode was for high-speed long distance transmission and multimode (in either the 50 µm or 62.5 µm core diameters) was used for lower speed short distance applications. Multimode 50 µm fiber had a lower cost and higher modal bandwidth than multimode 62.5 µm core fiber. Bandwidth is a measurement of the data carrying capacity of the fiber. A higher bandwidth fiber carries more data. See table below.
