In fiber optics, a ray that passes through the optical axis of an optical fiber (in contrast with a skew ray, which does not. )
Industry:Telecommunications
In fiber optics, a mode that shares energy among one or more other modes, all of which propagate together. Note: The distribution of energy among the coupled modes changes with propagation distance. 2. In microwave transmission, a condition where energy is transferred from the fundamental mode to higher order modes. Note: Energy transferred to coupled modes is undesirable in usual microwave transmission in a waveguide.
Industry:Telecommunications
In fiber optics, a loss of optical power at a splice or connector, caused by a lateral, i.e., transverse, offset of the mating fiber cores, which offset causes an imperfect transfer of the optical signal from the "transmitting" fiber to the "receiving" fiber. Note: The effect of a given amount of lateral offset will depend on other parameters such as the relative diameters of the respective cores. For example: if, because of manufacturing tolerances, the "transmitting" core is smaller than the "receiving" core, the effect will be less than if both cores were the same size. 2. An analogous loss of optical power caused by lateral misalignment of the fiber and optical source. Synonym transverse offset loss.
Industry:Telecommunications
In fiber optics, a band of wavelengths at which an optical fiber is sufficiently transparent for practical use in communications applications. Synonyms spectral window, transmission window. 2. In imagery, a portion of a display surface in which display images pertaining to a particular application can be presented, usually by using a graphical user interface (GUI. ) Note: Different applications can be displayed simultaneously in different windows. 3. A period during which an event can occur, can be expected to occur, or is allowed to occur.

In FDM, a reference frequency used for achieving and maintaining syntonization of the oscillators of a carrier system or for comparing the frequencies or phases of the signals generated by those oscillators.
Industry:Telecommunications
In fiber optic systems, any loss of optical power at a splice. Note: A practical splice, of physically realizable fibers, has losses attributable to a number of mechanisms, some of which are intrinsic to the fibers, and some of which are intrinsic to the method or device being used to join them.
Industry:Telecommunications
In fiber optic communications, pertaining to optical wavelengths greater than 1 m.

In FDM, a reference frequency used for achieving and maintaining syntonization of the oscillators of a carrier system or for comparing the frequencies or phases of the signals generated by those oscillators.
Industry:Telecommunications
In facsimile, the product of the total line length and the number of lines per unit length, divided by. 2. For rotating devices, the product of the drum diameter and the number of lines per unit length. Synonyms: diametral index of cooperation, international index of cooperation.
