LC pigtail material

LC pigtails are typically made of single-mode or multimode optical fiber with a 900 µm tight-buffered jacket, often LSZH or PVC, and a precision ceramic ferrule in the LC connector.Fiber Core and CladdingLC pigtails use optical fiber cores made of high-purity silica glass. Single-mode fibers (OS1/OS2) have a core diameter of 8–10 µm, while multimode fibers (OM3/OM4) have cores of 50 µm or 62.5 µm. The cladding surrounding the core is also silica, ensuring total internal reflection for light transmission .Jacket MaterialThe fiber is typically tight-buffered with a 900 µm jacket, which provides mechanical protection and flexibility. Common jacket materials include:LSZH (Low Smoke Zero Halogen): Reduces toxic fumes in case of fire, suitable for indoor installations .PVC (Polyvinyl Chloride): Standard indoor/outdoor use, cost-effective but less fire-safe than LSZH .Connector ConstructionThe LC connector on the pigtail features:Ceramic ferrule: Provides precise alignment of the fiber for low insertion loss and minimal back reflection.Plastic housing: Lightweight and durable, often color-coded for single-mode (blue) or multimode (beige/green) fibers.Polish type: Factory-polished connectors (UPC or APC) ensure high-quality signal transmission .Length and ConfigurationLC pigtails are available in standard lengths of 1–2 meters, with the bare fiber end designed for fusion or mechanical splicing to the main fiber cable. They can be single-fiber or ribbonized for mass fusion splicing .SummaryIn essence, an LC pigtail combines:High-purity silica fiber (single-mode or multimode)Tight-buffered jacket (LSZH or PVC)Precision LC connector with ceramic ferrule and factory polish This combination ensures low-loss, reliable connections in patch panels, ODFs, and FTTH/FTTx deployments .
