In optical communication, optical radiation having a wavelength less than approximately 1 m.
Industry:Telecommunications
In optical communication, a device that facilitates the splicing or breaking out of fiber optic cables. Note: The organizer provides means to separate and secure individual buffer tubes, fibers, and/or pigtails. It also provides means to secure mechanical splices or protective sleeves used in connection with fusion splices, and has means to contain the slack fiber that remains after the splicing process is completed.
Industry:Telecommunications
In general, extraneous energy, from natural or man-made sources, that impedes the reception of desired signals. 2. A coherent emission having a relatively narrow spectral content, e. G. , a radio emission from another transmitter at approximately the same frequency, or having a harmonic frequency approximately the same as, another emission of interest to a given recipient, and which impedes reception of the desired signal by the intended recipient. Note: In the context of this definition, interference is distinguished from noise in that the latter is an incoherent emission from a natural source (e. G. , lightning) or a man-made source, of a character unlike that of the desired signal (e. G. , commutator noise from rotating machinery) and which usually has a broad spectral content. 3. The effect of unwanted energy due to one or a combination of emissions, radiation, or inductions upon reception in a radiocommunication system, manifested by any performance degradation, misinterpretation, or loss of information which could be extracted in the absence of such unwanted energy. 4. The interaction of two or more coherent or partially coherent waves, which interaction produces a resultant wave that differs from the original waves in phase, amplitude, or both. Note: Interference may be constructive or destructive, i.e., it may result in increased amplitude or decreased amplitude, respectively. Two waves equal in frequency and amplitude, and out of phase by 180°, will completely cancel one another. In phase, they create a resultant wave having twice the amplitude of either interfering beam.
Industry:Telecommunications
In operations research, a procedure for locating the maximum or minimum of a linear function of variables that are subject to linear constraints. Synonym linear optimization.
Industry:Telecommunications
In open systems, the technique used by layered protocols in which a lower layer protocol accepts a message from a higher layer protocol and places it in the data portion of a frame in the lower layer.
Industry:Telecommunications
In open systems, an application service that (a) allows host terminals on a multi-user network to interact with other hosts regardless of terminal type and characteristics, (b) allows remote log-on by local-area-network managers for the purpose of management, (c) allows users to access information from another host processor for transaction processing, and (d) serves as a backup facility.
Industry:Telecommunications
In Open Systems Interconnection (OSI) --Architecture, a group of functional units in a given layer of a network in which all the functions performed by the functional units extend throughout the system at the same layer.
Industry:Telecommunications
In open systems architecture, the specification of application-layer data or application-protocol control information by using notation rules that are independent of the encoding technique used to represent the information.
Industry:Telecommunications
In open systems architecture, the distribution of network protocol among the various layers of the network.
Industry:Telecommunications
In non-ADP equipment, a CPU and firmware that are critical to the operation of the equipment. Note: An embedded processor is not subject to FIRMR regulation when used for control of devices such as weapons systems, communications devices, home appliances, automobile diagnostics, etc.
