8.2.1. Optical Fiber
Fiber optic cable is described by the amount of fibers contained within.
The cable described by the following terms:
• Glass
• Buffer
• Jacket
GLASS
Glass is the middle fiber in the cable. The data sent over the cable travels through the glass.
BUFFER
The buffer is the plastic coating that covers the fiber optic cable. The buffer protects the glass
from moisture and other damage.
JACKET
The jacket covers the buffer, providing greater protection to the glass.
The fiber consists of:
•
Core
•
Clad
The central part of a fiber is known as the core, and the material surrounding the core is known
as the clad. The clad has a lower index of refraction than the core, allowing light to be
completely reflected off the surface between the core and the clad. As a result, propagated light
remains entirely within the core. The cross-section of the cable is expressed as the core diameter
