Loss at a connector due to fiber end face angles being misaligned.Ībbreviation for angled physical contact. Amplifiers may be placed just after the transmitter (power booster), at a distance between the transmitter and the receiver (in-line amplifier), or just before the receiver (preamplifier). The angle between an incident ray and the normal to a reflecting or refracting surface.Ī device, inserted within a transmission path, that boosts the strength of an electronic or optical signal. Analog signals have frequency and bandwidth measured in hertz. A fiber with both a silica core and a silica cladding, regardless of the presence of a polymer overcoat or buffer.Ī signal that varies continuously (e.g., sound wavers). Adapter sleeve material is typically phosphor bronze, ceramic or polymer.Ī device that drops and/or add one or more optical channels to a signal.Ĭable made entirely of dielectric (insulating) materials without any metal conductors, armor, or strength members.Īlso known as all-glass fiber. Adapters can help mate or connect a variety of fiber optic cables together.Ī mechanical fixture within an adapter body that aligns and holds two terminated fiber connectors. It contains the split sleeve, also known as the interconnect sleeve, that holds the two ferrules together. Related to numerical aperture (NA).Īn adapter is a mechanical device designed to align fiber-optic connectors. The angle over which the core of an optical fiber accepts incoming light usually measured from the fiber axis. Examples include controlled power supplies, transistors, LEDs, amplifiers, and transmitters. Abrasives differ from polishing materials mainly in particle size.Ī device that requires a source of energy for its operation and has an output that is a function of present and past input signals.
Caused by impurities in the fiber such as hydroxyl ions.Ī material such as silicon carbide, aluminum oxide, silica, cerium oxide, emery or rouge that is used to figure, shape, or finish optical elements. The portion of optical attenuation in optical fiber resulting from the conversion of optical power to heat.
