Fiber Optic Cables

Fiber optic cables are thin strands of optically pure glass that carry digital information.

A single optical fiber has the following parts:

• Core - Thin glass center of the fiber where the light travels.
• Cladding - Low-refractive-index material that surrounds the core of an optical fiber to contain core light while protecting against surface contaminant scattering
• Buffer coating - Protective coating applied directly on the fiber

Multiple optical fibers are can be arranged in bundles. These bundles are protected by the cable's outer covering, called a jacket.

Optical fibers come in two types:

• Single Mode fibers
• Multimode fibers

Fiber optic cables have many advantages over other types of cables. They are thinner and more lightweight than traditional copper wires and also use less power and provide less signal degradation. The fiber optic cables have a higher capacity for information and power than copper wires. They are also non-flammable and are better suited for digital and light signal transmission.
