Splice holder assembly for an optical fiber cable splice closure

Abstract

A splice holder assembly of this invention is used in an optical fiber cable splice closure. The assembly includes a splice tray that is an open-topped enclosure in which is mounted splice organizing modules that hold optical fiber splices. The tray includes retainers that confine optical fibers in a lower portion of the tray, and that also support a card with a list of splice locations and optical fiber identities coupled by each splice. The card supports at least one splice cassette situated inside of the splice tray. The splice cassette includes a bottom portion and a cover. To the bottom portion, at least one splice organizing module is mounted. The cassette's bottom portion also has T-shaped engagements which hold respective protective tubes housing optical fibers, that run between a distribution unit of the closure and the cassette. The slack of the optical fibers can be wound in the bottom portion of the cassette and the ends of the optical fibers coupled together with splices inserted and held in the modules. The cassette cover includes depressed portions which engage with the inner sides of the bottom portion. Hinged tabs of the cassette's bottom portion can be folded into engagement with the cover to hold the cover over the top of the bottom portion. The cassette cover can be provided with a label indicating splice locations and the optical fibers coupled at each splice. A strap holds the splice cassette(s) in the splice tray.
