24、y be coupled into an optical fiber. 2.2.2 ATTENUATION Diminution of optical power (loss of light). Expressed in dB or (for optical fiber) in dB/km. 2.2.3 BANDWIDTH (FIBER BANDWIDTH) Range of signal frequencies carried on an optical fiber with a defined maximum signal distortion. For multimode fiber,

25、 fiber bandwidth is limited by signal distortion and is expressed as a product of signal bandwidth and propagation distance (MHz-km).SAE AS5382A Page 4 of 26 2.2.4 BOUND MODE In an optical fiber, a mode whose field decays monotonically in the transverse direction everywhere external to the core, and

26、 which does not lose power to radiation. Bound modes correspond to guided rays in the terminology of geometric optics. 2.2.5 BUFFER A typically polymeric coating that is used to protect an optical fiber from physical damage, moisture or chemicals, or to provide mechanical isolation. (See also: Fiber

27、 Optic Cable, Loose Tube Type and Tight Buffer Type) a. PRIMARY BUFFER The buffer coating applied by the fiber manufacturer during the fiber drawing operation. Sometimes referred to simply as “fiber coating” or “primary coating.” b. SECONDARY BUFFER Any number of coatings applied over the primary bu

28、ffer. Secondary buffers may be applied by the fiber manufacturer in an operation secondary to the draw process or by a cable manufacturer. A secondary buffer may also be known as “upjacketing.”2.2.6 CLADDING The optical material surrounding the core of an optical fiber. Cladding may be either glass

29、or polymeric, but must always be a material having an index of refraction lower than that of the core material. 2.2.7 CORE The central region of an optical fiber through which light is transmitted. The core must always be a material having an index of refraction higher than the surrounding cladding

30、material. 2.2.8 CUTOFF WAVELENGTH For a single-mode fiber under specified conditions, the wavelength at which the fibers second order mode is attenuated a specified amount. At wavelengths greater than the cutoff wavelength, a fiber is said to transmit single-mode. 2.2.9 DISPERSION A phenomenon due t

31、o a wavelength-dependent propagation velocity that results in signal distortion and pulse broadening. In optical fibers, several dispersion effects are present. Material (or chromatic) dispersion is that due to the constituent materials forming the fiber. Waveguide dispersion is due to the dependenc

32、e of the group and phase velocities on the numerical aperture, core diameter, and wavelength. Modal dispersion or distortion, important only in multimode fibers, results from the variation in path lengths for the different modes of the fiber. For single-mode optical fibers, material and waveguide di

33、spersion are the dominant causes of dispersion. 2.2.10 FAR-FIELD REGION That region, far from a source or radiating aperture, where the diffraction pattern is essentially the same as that observed at an infinite distance. SAE AS5382A Page 5 of 26 2.2.11 FIBER OPTIC CABLE One or more optical fibers c

34、ontained in a common jacket, usually with an integral strength member. a. LOOSE TUBE TYPE A cable design in which the fiber(s) is placed into a cavity which is much larger than the fiber with its primary buffer. This is intended to give the fiber mechanical independence in applications with high rel

35、ative motions and/or large temperature swings which could cause differential motion or stress inside conventional tight buffer cable structures. b. TIGHT BUFFER TYPE A cable design in which the secondary buffer(s) are applied in a manner resulting in firm contact between the primary buffer and subse

36、quent protective layers. c. SEMI-LOOSE STRUCTURE A cable design having a modified semi-loose structure that allows slight movement of the fiber and associated buffer between the inner jacket and the outer strength members. 2.2.12 FIBER OPTIC CABLE ASSEMBLY One or more fiber optic cables terminated w

37、ith two or more optical terminations (usually connectors) and so arranged that it can be handled as one unit. 2.2.13 HERMETIC COATING A thin coating (typically several hundred angstroms of amorphous carbon) applied directly to the fiber surface before the application of the primary buffer, for the p

38、urpose of sealing the fiber surface against hydrogen ingress and improving the fibers fatigue resistance. 2.2.14 INDEX OF REFRACTION (REFRACTIVE INDEX) The index of refraction of a medium, denoted by n, is the ratio of the velocity of light in vacuum to the velocity of light in that medium. 2.2.15 M

39、ODE In any cavity or transmission line, one of those electromagnetic field distributions that satisfies Maxwells equations and the boundary conditions or that can be designated by a radiation pattern in a plane transverse to the direction of travel. Usually understood to be a single optical path or

40、ray of light. 2.2.16 MODE FIELD DIAMETER The measure of the width of the guided optical powers intensity distribution in a single-mode fiber. Usually specified instead of fiber core diameter for single-mode fiber. 2.2.17 NEAR FIELD REGION That region, near a source or radiating aperture, where the d

41、iffraction pattern differs significantly from that observed at an infinite distance. SAE AS5382A Page 6 of 26 2.2.18 NUMERICAL APERTURE (NA) A measure of the light gathering ability of a fiber. NA is commonly defined as the sine of the acceptance angle (a) of an optical fiber multiplied by the refra

42、ctive index of the material in contact with the entrance face of the fiber. For a step indexfiber in air, NA = 2212nn- where n1and n2are the refractive indices of the core and cladding materials, respectively. (See also: Acceptance Angle) 2.2.19 OPTICAL FIBER A filament, made of dielectric materials

43、, that guides light.a. GRADED INDEX OPTICAL FIBER An optical fiber in which the refractive index of the core varies with radial distance from the fiber axis and is lowest near the cladding. b. STEP INDEX OPTICAL FIBER An optical fiber characterized by a uniform refractive index in the core and a sha

44、rp decrease in refractive index at the core-cladding interface. c. SINGLE-MODE OPTICAL FIBER An optical fiber in which only the lowest order bound mode can propagate at the wavelength of interest. (See also: Bound Mode) d. MULTIMODE OPTICAL FIBER An optical fiber which will allow more than one bound

45、 mode to propagate. (See also: Bound Mode) 2.2.20 OPTICAL TIME DOMAIN REFLECTOMETER (OTDR) A measurement device used to characterize a fiber, wherein an optical pulse is transmitted through the fiber and the resulting light scattered and reflected back to the input is measured as a function of time.

46、 Useful in identifying defects andother localized losses. 2.2.21 PREFORM A glass structure (usually a rod) from which an optical fiber may be drawn. 2.2.22 QUALIFICATION INSPECTION Qualification Inspection is a process that demonstrates that a component is capable of fully conforming to all the requ

47、irements defined in a standard. Qualification Inspection includes definition of the measurements, tests, analysis, and associated data which provides consistent rationale for acceptance of a particular suppliers design as meeting the standard requirements typically prior to acquisition by the Purcha

48、ser. 2.2.23 QUALIFIED PRODUCTS LIST A Qualified Products List is a list of suppliers whose products have been evaluated to a defined process and who are authorized to provide those products to a purchaser upon request. When a Qualified Products List is specified, only approved suppliers are authoriz

49、ed to provide products under the part number defined in the component standard. A Qualified Products List is established by a Qualifying Activity. SAE AS5382A Page 7 of 26 2.2.24 QUALIFYING ACTIVITY A Qualifying Activity is a function established by a Purchaser or group of Purchasers that has a defined process used to consistently evaluate all suppliers products in accordance with the component standard. 2.2.25 QUAL
