CONNECTORS / TERMINATIONS WITH FIBER GLOSSARY

　　Aramid Yarn: Yellow fibers that provide cable tensile strength, support and additional protection for the optical fiber bundle. Kevlar? is particular brand of aramid yarn.

　　Acceptance Angle: The angle over which the core of an optical fiber accepts incoming light; usually measured from the fiber axis. Related to numerical aperture (NA).

　　All-dielectric cable: Cable made entirely of dielectric (insulating) materials without any metal conductors, armor or strength members.

　　Angle of Incidence: The angle between the incident ray and the normal to a reflecting or refracting surface.

　　Attenuation: Reduction of signal magnitude (or loss) normally measured in decibels. Fiber attenuation is normally measured per unit length in decibels per kilometer. The decrease in signal strength along a fiber optic waveguide caused by absorption and scattering. Attenuation is usually expressed in dB/km.
