How to connect pigtail fiber and leather fiber

To connect leather-sheathed fiber cables to pigtail fibers, carefully strip the cable, expose the bare fibers, and fusion or mechanically splice them to the pigtail for a stable, low-loss connection.Understanding the ComponentsFiber optic pigtails are short lengths of optical fiber with a factory-terminated connector on one end and a bare fiber on the other. The connector end plugs into equipment or patch panels, while the bare fiber is designed for splicing to incoming cables in the field . Leather-sheathed or dual-core cables contain two optical fibers within a protective outer layer, often used for two-way data transmission . The leather sheath provides mechanical protection but must be carefully removed to access the fibers.Step-by-Step Connection ProcessPrepare the Cable: Peel off the outer leather sheath carefully to expose the fiber bundle inside. Use fiber strippers or precision cutting tools to avoid damaging the fibers .Expose the Bare Fiber: Remove the protective coating from each fiber to reveal the bare optical fiber. Ensure that the exposed lengths are equal for proper alignment during splicing .Splice to the Pigtail: Insert the bare fiber into the connector of the pigtail. This can be done using either fusion splicing (melting fibers together for minimal loss) or mechanical splicing (aligning fibers in a precision sleeve), .Secure the Connection: Tighten the connector or splice holder to ensure stability. Avoid bending or stretching the fibers excessively, as this can cause signal loss or breakage .Test the Connection: Use a fiber tester to verify signal integrity. The tester will confirm low insertion loss and proper alignment, ensuring the connection is reliable .Best PracticesMaintain a clean environment to prevent dust or contaminants from entering the splice, which can degrade performance .Handle fibers gently to avoid microbends or fractures.Use factory-terminated pigtails whenever possible to save time and ensure consistent performance compared to field-terminated connectors . By following these steps, you can achieve a stable, low-loss connection between leather-sheathed fiber cables and pigtail fibers, suitable for high-performance optical networks.
