Glossary
Adapter
A device used to mate fiber connectors of the same or different styles.
Attenuation
A loss of optical power, mostly due to poor connections or to light diffusion
caused by imperfections in the fiber material (scattering).
Bandwidth
The range of frequencies a fiber can transmit without significant power loss.
Buffer
A layer of protective material surrounding the cladding of a fiber. The buffer
helps protect the fiber from physical damage.
Cladding
A glass coating surrounding a fiber core to reflect light back into the core.
Core
The light-conducting central portion of an optical fiber.
