Specialty Optical Fiber Specifications

Help with Specialty Optical Fiber specifications:

Fiber Type

	Fiber Type:
	Your choices are...
	Bare Fiber		Bare fiber consists of a fiber optic core and cladding. Bare fiber can be single mode or multimode.
	Attenuating		Attenuating fibers are used at the ends of optical fiber links to adjust the transmitted signal down to a controlled degree of attenuation, or to provide reflection-free termination. To achieve this, a short piece of ATN is used in the attenuator.
	Double Clad		Double clad fiber is used for high power applications such as fiber lasers, amplifiers, etc.
	Erbium Doped		Erbium-doped fiber amplifiers (EDFA) are widely used in the optical fiber telecommunications industry because they allow transmission transparency. New-generation EDFAs include power amplifiers, pre-amplifiers and in-line amplifiers for C- and L-bands.
	Erbium / Ytterbium Doped		Optical fibers are doped with both erbium and ytterbium.
	Fiber Laser		Fiber lasers use a lasing medium that consists of an optical fiber doped with low levels of rare-earth halides for amplifying light. The output is tunable over a broad range and can be broadband. Laser diodes are used for pumping because of the fiber laser's low threshold power. Laser diodes also eliminate the need for cooling.
	Graded Index		With graded index fibers, the refractive index of the core is in the form of a parabolic curve and decreases toward the cladding.
	High NA		High NA fibers capture more input with very low, bend-induced attenuation.
	Metallized		Fibers are coated with metals for increased temperature resistance, ease of soldering, and suitability for harsh environments.
	Mid-IR		Mid-IR fiber is designed to provide ultra-low loss optical transmission in the mid-Infrared spectrum (2 to 10 microns).
	Photonic Crystal		Photonic crystal fibers use an air-filled cladding region to confine light in very small mode field areas.
	Photosensitive		Photosensitive fibers exhibit uniform and controlled photosensitivity to conventional UV radiation techniques. The quality of the Bragg grating depends heavily on the UV-sensitive fiber used to write the grating.
	Polarization Maintaining		Fibers maintain the polarization of entering light.
	Ytterbium Doped		Optical fiber is doped with yterrbium.
	Other		Other unlisted fiber types.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Fiber Mode:
	Your choices are...
	Single Mode		Single mode fibers have a small core, only a few times the wavelength of light transmitted, that allows only one mode of light to propagate. Single mode fiber is commonly used with laser sources for high speed, long distance links.
	Multimode		Multimode fibers have a core diameter much larger than the wavelength of light transmitted to allow many modes of light to propagate. Multimode fiber is commonly used with LED sources for lower speed, short distance links.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Fiber Core Size		Fiber core size is the size of the light-conducting, central portion of an optical fiber, an area composed of material with a higher index of refraction than the cladding. The core size is smaller for single mode and larger for multimode fibers.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Fiber Performance

	Wavelength		This is the wavelength for which the fiber optic cable was designed.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Numerical Aperture		Numerical aperture (NA) measure a fiber's light-gathering ability. It is the maximum angle to the fiber axis at which light is accepted and propagated through the fiber. NA = sin a, where a is the acceptance angle. NA is also used to describe the angular spread of light from a central axis, as in exiting a fiber, emitting from a source, or entering a detector.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Maximum Attenuation		Maximum attenuation is the decrease in signal strength along a fiber optic cable caused by absorption and scattering. Attenuation is usually expressed in dB/km.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Bending Radius		This is the smallest radius that an optical fiber or fiber cable can bend before increased attenuation or breakage occurs.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Operating Temperature		This is the full required range of ambient operating temperature.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
