Progression: Maintenance Tech II - III Conventional( Latest Update)

buffer tubes - ANSWER A flexible cylindrical structure that houses, compartmentalizes, and protects smaller groups of optical fibers within larger multi-fiber cables. pigtails - ANSWER A length of optical fiber with a connector at only one end, which may be spliced to a smaller diameter optical fiber for testing or termination. acceptance testing - ANSWER Length and loss test of fiber-optic cable that is typically performed twice—when the cable is received from the manufacturer and after the cable is installed and spliced into the network. fiber-to-the-x (FTTx) - ANSWER Multipurpose term which includes FTTH (fiber-to-the-home), FTTC (fiber-to-the-curb), FTTP (fiber-to-the-premises), etc. mid-entry splice - ANSWER Also called an express splice. A splice in fiber-optic cable where only a select number of optical fibers are cut and spliced. The remaining buffer tubes and optical fibers remain untouched. Micron (μm) - ANSWER A micrometer: The equivalent of one one-millionth (1 × .000001) of a meter. Hermetically sealed closures are used in aerial installations in areas of high temperature and low humidity. - ANSWER False Splice closures are used to provide the transition between outdoor optical fiber to indoor fiber. - ANSWER False Splice closures provide weather protection to the exposed buffer tubes, optical fibers, and splices when the fiber-optic cable jacket is removed and spliced in the outside fiber-optic cable network. - ANSWER True Splice closures provide strain relief to the fiber-optic cable from axial forces applied to any of the cables. - ANSWER True What are the general categories of optical splice applications? - ANSWER Optical splice applications can generally be categorized as: in-line splices, branch splices, splitters, mid-entry splices, pigtails, restoration sp
