Fiber optic pigtails LC and FC

An LC-FC fiber optic pigtail is a short fiber cable terminated with an LC connector on one end and an FC connector on the other, designed for splicing and high-performance optical connections.

Overview

Fiber optic pigtails are short lengths of fiber optic cable with a connector on one end, used to connect devices that lack built-in connectors, such as lasers, receivers, and switches . The LC-FC pigtail combines the small, high-density LC connector with the durable, threaded FC connector, making it suitable for compact installations while ensuring stable, high-performance connections .

Key Features

• Fiber Type: Available in singlemode (OS1/OS2) and multimode (OM1, OM2, OM3) . Singlemode is ideal for long-distance transmission, while multimode is used for shorter distances.
• Connector Types: LC (small form factor, push-pull) and FC (screw-on, high durability) provide flexibility for different network equipment .
• Jacket Options: Common jackets include OFNR (riser-rated, flame-retardant PVC) and LSZH (low-smoke zero halogen) for safety in building installations .
• Bend-Insensitive Fiber: Reduces signal loss when bent or twisted, improving installation in tight spaces .
• Ferrule Material: High-precision zirconia ceramic ferrules ensure long life, stability, and interchangeability .
• Cable Diameter: Typically 0.9mm or 2.0mm tight-buffered for easy stripping and splicing .

Applications

• Fusion or Mechanical Splicing: Connects fiber optic cables to devices or patch panels .
• Data Transmission: Supports high-speed networks, including 10 Gbps over multimode fiber up to 2 km .
• Optical Test Equipment: Used in labs and field testing for precise measurements.
• CATV and Sensors: Suitable for optical communication and sensor systems .

Advantages

• Low Insertion Loss: Ensures minimal signal degradation during connection .
• High Flexibility: Bend-insensitive fibers and small LC connectors allow installation in dense racks or limited spaces .
• Custom Lengths: Many suppliers offer pigtails in various lengths to match installation requirements .
• Durability: FC connectors provide secure, threaded connections for high-vibration environments .

Summary

An LC-FC fiber optic pigtail is ideal for applications requiring a combination of compact LC connections and robust FC terminations, supporting both singlemode and multimode fibers. It is widely used in network installations, splicing, and high-density optical setups, offering low loss, flexibility, and reliable performance .
