Correct Answer: Splice Closures ar e used to protect optical fibers and splices against a full range of environmental changes in a erial installations or below ground in vaults. When preparing a fiber -optic cable for splicing, what is the purpose of removing approximately 2.5 cm (1 inch) of jacket and any armor that is present, from the end of the cable? Correct Answer: To access the cables rip cord and to check the cutting depth of the knife or ringing tool. What does water do to the glass core of an optical fiber? Correct Answer: Wate r causes the glass core of the optical fiber to become opaque, which degrades the signal as its transported through the fiber. When preparing a splice closure, what should be done with the fiberglass rod strength member that runs down the center of loose -tube fiber optic cable?

What is the purpose of splice trays inside splice closures? Correct Answer: Splice trays are designed to provide protection for mechanical splices, fusion splice protectors, and optical splitters as well as provide storage for the required fiber slack. How should the buffer tubes be secured in the closure? Correct Answer: The b uffer tubes should be secured with tie wraps to allow slight movement without pulling or stressing the optical fibers. How are optical splices secured in a splice tray? Correct Answer: Retaining clips hold optical splices in place in a splice tray. What is the Purpose of Buffer tubes in a fiber optic cable? Correct Answer: Buffer tubes protect and separate the optical fiber in smaller bundles When splicing fiber -optic cable, why is it a good safety practice to clean off fiber strippers and other hand tools after each use? Correct Answer: To prevent the accidental transfer of fiber debris or fiber chips onto clean hands.
