How to open an SDSSS fiber optic cable

Opening an SDSSS fiber optic cable requires careful stripping of the outer jacket and Kevlar fibers using specialized tools to access the internal optical fibers without causing damage. Tools You Will NeedThree-hole jacket stripper: For removing the outer cable jacket cleanly. Kevlar fiber cutter or scissors: To cut the aramid strength members safely.

Fiber optic stripper: For removing the protective coating from individual fibers. Precision fiber cleaver: To produce a flat, smooth end-face for splicing or connectorization. Lint-free wipes and 99% isopropyl alcohol: For cleaning exposed fibers.

Visual Fault Locator (VFL): Optional, to verify fiber integrity after opening.

Step-by-

Step Procedure

Prepare the Cable: Inspect the SDSSS cable for any visible damage and ensure it is de-energized. Slide any connector boots or protective covers away from the section you plan to open. Strip the Outer Jacket: Use a three-hole jacket stripper to remove approximately 2 inches (50 mm) of the outer jacket.

This exposes the internal yarn and fiber strands without nicking the fibers. Cut Kevlar Strength Members: Carefully trim the exposed Kevlar fibers using Kevlar shears. Avoid cutting or scratching the optical fibers themselves.

Separate and Strip Individual Fibers: Use a fiber optic stripper to remove the protective coating from each fiber. This step is critical to prevent damage and ensure proper splicing or connectorization. Cleave the Fiber: Place the stripped fiber into a precision cleaver to create a flat, mirror-like end-face.

Proper cleaving minimizes signal loss and ensures reliable connections. Clean the Fiber: Wipe the fiber with lint-free wipes and isopropyl alcohol to remove any debris or contaminants. Optional Testing: Use a Visual Fault Locator to check that the fiber is intact and properly prepared for splicing or termination.

Safety Considerations

Do not look directly into fiber ends; invisible laser light can cause eye damage. Handle fiber shards carefully; they can penetrate skin and cause injury. Work in a clean, well-lit area to avoid contamination and accidental damage.

By following these steps and using the proper tools, you can safely open an SDSSS fiber optic cable and prepare it for splicing, connectorization, or inspection while minimizing the risk of signal loss or fiber damage.
