Automatic stripping and welding of optical cables

Automatic fiber stripping and welding methods combine precision coating removal with fusion splicing to ensure high-quality, reliable optical connections.Automatic Fiber StrippingAutomatic fiber stripping systems are designed to remove protective coatings from optical fibers without damaging the glass cladding. These systems can handle a variety of coatings, including acrylate, polyimide, PVC, carbon, and metallic layers, and are suitable for both single fibers and fiber ribbons . Key methods include:Mechanical Stripping: Uses precision blades to remove polymer coatings. Automated mechanical strippers can adjust for fiber diameter and strip length, ensuring consistent results for high-strength fusion splices .Thermal Stripping: Applies controlled heat to soften or burn off coatings. Thermal strippers can be fully automated with adjustable temperature and timing, suitable for delicate fibers and high-throughput production .Plasma-Assisted Stripping: Non-contact method using plasma to etch away coatings, ideal for metallic or polyimide layers. This preserves fiber strength and is effective for high-performance applications like fiber Bragg gratings .Burst Technology: Super-heated air or nitrogen is precisely applied to burst away polymer coatings cleanly, providing high-strength fiber ends for fusion splicing . Automatic systems often integrate cleaning and preparation steps, including residue removal and fiber cleaving, to prepare fibers for immediate splicing .Automatic Welding (Fusion Splicing)After stripping, fusion splicing is the standard method for welding optical fibers. Automated fusion splicers align fiber cores precisely and use an electric arc to fuse them, producing low-loss, high-strength joints. Features of modern automated splicers include:Core Alignment: Active or passive alignment ensures minimal optical loss.Recipe Control: Pre-programmed settings for different fiber types and coatings.Integrated Cleaving and Inspection: Some systems combine stripping, cleaving, and splicing in a single workflow for maximum efficiency .Integrated Automation SolutionsCompanies like AFL, Komax, LASER COMPONENTS, and 3SAE Technologies offer fully automated fiber prep and splicing systems that combine stripping, cleaning, cleaving, and fusion splicing. These systems improve throughput, reduce human error, and are adaptable to various fiber diameters and coatings . Advanced units may include:Window Stripping: Removing coatings from mid-fiber sections for specialized applications.High-Strength Splice Preparation: Ensuring tensile strength above 20 N for demanding environments.Non-Contact Coating Removal: Preserves fiber integrity for sensitive or metallic-coated fibers.SummaryAutomatic stripping and welding of optical fibers involve precision coating removal using mechanical, thermal, or plasma-assisted methods, followed by fusion splicing for permanent, low-loss connections. Fully automated systems integrate these steps, offering high reliability, repeatability, and efficiency for telecommunications, data centers, and specialized fiber optic applications .
