Cable/Fiber Access Tools, Ribbon Splitting Tool Part Number: RST-000 Corning manufactures a full line of products designed to quickly, easily and safely access Corning fiber optic cables in mid-span situations. These products allow the user to enter a cable and access one or more fibers, without disturbing the continuity of other fibers at that location. Drop cables can be spliced without disturbing working traffic on other fibers. The ribbon splitting tool is designed to allow separation of 12-, 24- and 36-fiber ribbons into smaller ribbons. Multiple slots on the tool offer the ability to separate the original ribbon into two different ribbons with varying fiber counts. The tool has slots to separate the ribbon into the following smaller ribbon fiber counts: 2/2, 2/4, 2/6, 4/4, 2/10, 4/8, 6/6, 12/12 and 12/24.
