![]() The average level of power in a signal that varies with time.Īn array of curved planar waveguides that separates many optical channels at once. APDs can detect faint signals but require higher voltages than other semiconductor electronics. Electrons generated at a p/n junction are accelerated in a region where they free an avalanche of other electrons. Can be fixed, manually adjustable, or electrically adjustableĪ semiconductor photodetector with integral detection and amplification stages. Attenuation is usually expressed in dB/km.Ī device used to measure power loss in fiber optic connectors, cables, or systems.Ī passive device for reducing the amplitude of a signal without appreciably distorting the waveform. The decrease in signal strength along a fiber optic waveguide caused by absorption and scattering. Fiber attenuation is normally measured per unit length in decibels per kilometer. Reduction of signal magnitude, or loss, normally measured in decibels. It contributes to the noise figure of the EDFA which causes loss of signal-to-noise ratio (SNR). A thin, dielectric or metallic film applied to an optical surface to reduce its reflectance and thereby increase its transmittance.Ī protective layer, usually metal, wrapped around a cable.Ī background noise mechanism common to all types of erbium-doped fiber amplifiers (EDFAs). A style of fiber optic connector with a 5°-15° angle on the connector tip for the minimum possible backreflection.Ī photodiode that exhibits internal amplification of photocurrent through avalanche multiplication of carriers in the junction region.Īntireflection coating. 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. Optical connectors are precision polished allowing for maximum signal transfer accuracy.Fiber Optic Terms and Definitions A Absorption.24K Gold Plated Connectors provide great listening experience Constructed with durable black PVC outer layer, low-jitter synthetic fiber and heavy metal connectors to dampen vibration.Perfect for uncompressed PCM audio, compressed 5.1 to 7.1 surround sound systems including Dolby Digital Plus, DTS-HD High Resolution, ADAT's and LPCM Connect any audio component like CD player, DVD player, or other digital audio source to both home theater system of your receiver and recorder.Supports one male input to two female outputs Please note that the two female outputs can work together at the same time! Toslink fiber optic audio splitter allows you to connect one optical audio source and split it into two receiving devices, such as a A/V receiver and a soundbar. ![]()
