Fiber optic pigtail model FC

FC fiber optic pigtails are high-performance connectors with a threaded ferrule design, used to splice or connect optical fibers in single-mode or multimode networks.

Overview

The FC (Ferrule Connector) fiber optic pigtail is a short optical fiber cable with one end terminated with an FC connector and the other end left as a bare fiber for splicing or integration into network devices such as transceivers, switches, and routers . Developed in Japan, the FC connector features a metal sleeve and threaded coupling, providing secure and stable connections, particularly in environments where vibration or movement may occur . Its simple structure makes it user-friendly, though it is sensitive to dust, which can affect insertion and return loss performance .

Types and Fiber Options

FC pigtails are available in both single-mode (9/125 µm) and multimode (50/125 µm, 62.5/125 µm, and 10Gb multimode 50/125 µm) configurations . They can be terminated with different connector polish types, including PC, UPC, and APC, depending on network requirements . Single-mode FC pigtails typically have yellow jackets, multimode OM1/OM2 are orange, and OM3 10Gb laser-optimized versions are aqua, with additional colors available for multi-fiber identification .

Cable and Packaging Options

FC pigtails are commonly made with 900 µm tight-buffered cables, but custom diameters such as 1.6 mm, 1.8 mm, 2.0 mm, and 3 mm are also available . They can be supplied as simplex (single fiber) or duplex (dual fiber), and in individual, 6-pack, or 12-pack configurations. Multi-fiber versions, including 6-fiber or 12-fiber jacketed pigtails and ribbon cable pigtails, are also offered for high-density applications . The bare fiber end can be fusion spliced to other fibers or mounted in splice trays or connector panels .

Applications

FC pigtails are widely used in telecommunications, data centers, and high-speed network environments. They are ideal for fusion splicing, connecting optical devices, and ensuring low insertion loss and high stability in fiber optic networks . Their threaded design provides secure connections in equipment racks and patch panels, making them suitable for both indoor and controlled outdoor installations.

Key Considerations

When selecting an FC fiber optic pigtail, consider:

• Fiber type: single-mode vs. multimode
• Connector polish: PC, UPC, or APC
• Cable diameter and jacket type: standard 900 µm or custom sizes
• Length: customizable to project requirements
• Packaging: individual or multi-pack for bulk installations Proper selection ensures optimal transmission efficiency, network stability, and extended service life of the fiber optic system .
