fiberless optics
->
free-space optics
Free-space optics (FSO), also known as optical wireless communication or optical wireless networking, refers to the transmission of data using modulated beams of light through free space (air or a...
fiberscope
An optical instrument consisting of an objective lens, a coherent (usually flexible) fiber bundle and an eyepiece to examine the output of the fiber bundle.
flexible imagescope
->
fiberscope
An optical instrument consisting of an objective lens, a coherent (usually flexible) fiber bundle and an eyepiece to examine the output of the fiber bundle.
fused array of fibers
Optical fibers fused together to form a solid, vacuum-tight assembly in the form of a slab or rod. Discs or rectangular shapes having ground and polished surfaces perpendicular to the fiber lengths...
hard-clad silica fiber
A type of optical fiber in which a silica core is surrounded by a hard polymer or similar material much stronger than the customary cladding material.
high-loss fiber
Optical fiber in which the attenuation exceeds the normally acceptable level for long-haul or data communications use.
imagescope
->
fiberscope
An optical instrument consisting of an objective lens, a coherent (usually flexible) fiber bundle and an eyepiece to examine the output of the fiber bundle.
large-core fiber
Optical fiber with a large core, often a step-index fiber; "large'' is at times defined as greater than 85 µm.
legacy fiber
Older fiber optic cable that may not be suitable for state-of-the-art applications and that is difficult for suppliers to sell.
lightguide
->
fiber optic lightguide
A bundle of optical fibers arranged randomly for the purpose of transmitting energy, not an image.
liquid core optical fiber
Multimode straight fiber capable of transporting linearly polarized light with any incident polarization angle, and in which no form of internal stress can develop that could lead to birefringence.
low-loss fiber
Optical fiber that transmits a greater percentage of input light than does high-loss step-index fiber. Low-loss fiber requires higher purity materials and a more sophisticated drawing process and...
monomode optical waveguide
->
single-mode waveguide (or fiber)
An optical waveguide in which only the lowest order bound mode, which may consist of a pair of orthogonally polarized fields, can propagate at the wavelength of interest.
multifiber cable
Fiber optic cable bearing many fibers independently sheathed and capable of carrying unrelated signals. They often surround a central strength member, and can be either loose- or tight-buffered. One...
multifiber joint
A fiber optic connector or splice that mates two multifiber cables, optically aligning all of the individual fibers simultaneously.
multifibers
An array of optically distinct fibers that are fused into one strand. They are used to keep the resolution efficiency of the smaller, single fibers and eliminate difficulty in handling. Their...
multihaul transceiver
A multihaul transceiver is an optical transceiver module designed to support multiple network architectures or transmission technologies within a single compact device. It offers versatility and...
multimode fiber
->
multimode optical waveguide
An optical waveguide that will allow more than one bound mode to propagate.
optical fiber
Optical fiber is a thin, flexible, transparent strand or filament made of glass or plastic used for transmitting light signals over long distances with minimal loss of signal quality. It serves as a...
plastic-clad silica fiber
An optical waveguide having a silica core and a plastic cladding.
pluggable optics
Pluggable optics, also known as pluggable transceivers or optical transceivers, are modular devices used in optical communication systems to transmit and receive data over optical fibers. They are...
Raman fiber probe
A flexible fiber cable with a small diameter that transports light from the excitation laser to the target. Used in Raman spectroscopy, the probe is capable of obtaining high-quality data at high...
randomized fiber optic cable
Fiber optic cable in which the arrangement of fibers within the bundle has been made random so that output light will be uniformly distributed and not relay the image of the light source at the input...
rare-earth doped fiber
An optical fiber in which ions of a rare-earth element, such as neodymium, erbium or holmium, have been incorporated into the glass core matrix, yielding high absorption with low loss in the visible...
revolving lens fiber optic scanner
A sequential scanning device, utilizing a revolving lens, in which the cathode-ray tube image is transformed into a circle of fibers. The rotating lens focuses each fiber successively on a multiplier...
sapphire optical fiber
Sapphire optical fiber is a type of optical fiber made from single-crystal sapphire, which is a form of aluminum oxide (Al2O3) that is highly transparent in the infrared region of the electromagnetic...
single-mode waveguide (or fiber)
An optical waveguide in which only the lowest order bound mode, which may consist of a pair of orthogonally polarized fields, can propagate at the wavelength of interest.
step index fiber
An optical fiber in which the core is of uniform refractive index.
ultraviolet fiber optics
Ultraviolet (UV) fiber optics refers to optical fibers that are designed and optimized for the transmission of ultraviolet light, which is electromagnetic radiation with wavelengths shorter than...
w-type fibers
->
double-clad fiber
Double-clad fiber (DCF) is a specialized optical fiber that features two concentric cladding layers surrounding a core. The design of double-clad fibers allows them to be used in various...
