Tools for opening windows in fiber optic cables

Mid-span slit and ring tools, thermal strippers, and fiber jacket strippers are commonly used to access the interior fibers of fiber optic cables safely.Mid-Span Access ToolsMid-span slit and ring tools are designed to give technicians quick access to the interior optical fibers without cutting or damaging them. For example, the MS-446 Mid Span Slit & Ring Tool is suitable for thick-walled cables with diameters from 8.7 mm to 14.6 mm, allowing precise removal of the outer jacket to expose fibers for splicing or testing (Jonard Tools), .Fiber Jacket StrippersFiber jacket strippers are hand tools used to remove the protective outer layers of fiber optic cables. Tools like the JIC-125 Fiber Optic Stripper can strip 250 µm buffer coatings to expose the 125 µm optical fiber, making them essential for preparing fibers for termination or splicing (Jonard Tools), .Thermal StrippersThermal strippers use controlled heat to remove coatings from optical fibers, including baked-on or difficult-to-strip materials. The TSAB-40 Thermal Stripper features an adjustable heater up to 200°C and can handle fibers with cladding diameters from 30 µm to 1000 µm, including common 250 µm, 400 µm, and 900 µm coated fibers (Jonard Tools), .Complete Fiber Optic Tool KitsComprehensive kits often include jacket strippers, shears, scribes, polishing tools, and cleaning accessories. These kits are designed for both field and lab use, enabling technicians to perform fiber preparation, termination, and testing efficiently. Examples include Glenair Fiber Optic Termination and Test Probe Kits, which provide all necessary tools for precise fiber handling and measurement (Glenair), .Additional AccessoriesOther useful tools include polishing films, cleaning kits, and test probes to ensure optimal fiber performance after opening the cable. These accessories help maintain low insertion loss and high-quality connections during installation or repair (Corning, CommScope), . Using the correct combination of these tools ensures safe, efficient, and precise access to fiber optic cables, minimizing the risk of fiber damage and maintaining signal integrity.
