FIBER OPTIC DEFINITIONS

Attenuation: Loss of signal power. Attenuation is typically measured in decibels per kilometer (dB/km) at a specific wavelength.
Bandwidth:

Potential information carrying capacity, the amount of information that can be sent over a communication channel, increases with the frequency.

Bend Radius: Radius a fiber can bend before the risk of breakage or increase in attenuation.
Buffering: A protective material extruded directly on the fiber coating to protect it from the environment.
Cable Assembly: Fiber Optic cable that has connectors on one or both ends.
Cladding: The material surrounding the core of an optical waveguide. The cladding should have a lower index of refraction in order to steer the light in the core.
Coating: A material put over the cladding, during the drawing process, to protect the fiber from the environment.
Core: The central region of a fiber through which light is transmitted.
Decibal (dB): The unit for measuring the relative strength of a signal.
Dispersion: The spreading of light pulses as they travel down the fiber.
Fresnal Reflection Losses: Reflection losses incurred at input and output of optical elements due to the difference in refractive index between glass and the immersion medium.
Graded Index Fiber: Fiber design of optical fiber having a core refractive index that decreases almost parabolically and radially outward toward the cladding.
Index of Refraction: The ratio of light velocity in a vacuum to its velocity in a given transmitting medium.
Jumper Assembly: A cable assembly with connectors attached on both ends.
Micron (pm): Micrometer; one millonth of a meter.
Mode: A term used to describe a light path through a fiber.
Modulation: Coding of information onto the carrier frequency. This includes amplitude, frequency, or phase.
Multimode Fiber: An optical waveguide in which light travels in multiple modes.
Numerical Aparture: The number that expresses the light gathering power of a fiber.
Pigtail: A cable assembly with connectors at one end.
Scattering: A property of glass which causes light to deflect from the fiber and contributes to losses.
Singlemode Fiber: An optical waveguide in which only the lowest-order bound mode, which may consist of a pair of orthogonally polarized fields, can optical propagate at the wavelength of interest.
Step-Index Fiber: Optical Fiber which has an abrupt change in its refractive index, due to a core and cladding that have different indices of refraction. Typically used for singlemode.
Tight Buffer: A type of cable construction where each fiber is lightly buffered by a protective thermo-plastic coating to a diameter of 900pms.
Wavelength: The distance between crests of a waveform.
