A Fiber Optic Cable is a network cable that contains strands of glass fibers inside as insulated casing. These cables are designed for long distance and very high bandwidth (gigabit speed) network communication. Recently Fiber optic cables are increasing being used instead of copper cables.
Accordingly to the usage, fiber optic cable can be divided into indoor cable and outdoor cable. Accordingly to fiber type, fiber optic cable can be divided into single mode G652 Cable, SM G657 cable, OM1 cable, OM2 cable, OM3 cable, and OM4 cable.
Loose tube cable, used in the majority of outside-plant installation, and tight-buffered cable, primarily used inside buildings. In a loose tube cable design, color-coded plastic buffer tubes house and protect optical fibers. A gel-filling compound impedes water penetration. Excess fiber length insulates fibers from stresses of installation and environment loading. Buffer tubes are stranded around a dielectric or steel central member, which serves as an anti-buckling element. Loose-tube cables typically are used for outside-plant installation in aerial, duct and direct buried applications.
