1 core of pigtail cable

A 1-core fiber optic pigtail is a single optical fiber with a factory-terminated connector on one end and a bare fiber on the other, used for splicing into a fiber network.

Structure and Design

A 1-core pigtail consists of one optical fiber (single-core) with a factory-installed connector on one end and a bare fiber on the other end for splicing into a main fiber cable . The connector end is polished and tested to ensure low insertion loss and high return loss, while the bare end is designed for fusion or mechanical splicing in the field . Unlike patch cords, which have connectors on both ends, pigtails are intended for permanent integration into fiber networks .

Applications

1-core pigtails are commonly used in FTTH (Fiber to the Home) networks, ODFs (Optical Distribution Frames), fiber terminal boxes, and splice trays . They allow for fast, reliable, and low-loss connections between bulk fiber cables and network equipment. Their single-core design is ideal for incremental network expansion and precise fiber management.

Technical Features

• Connector Types: SC, LC, ST, or APC, depending on network requirements .
• Fiber Type: Single-mode (OS2) or bend-insensitive fibers like G657A1 for indoor/outdoor use .
• Length: Typically 0.5m to 2m, but can vary based on installation needs .
• Protection: Some pigtails use water-blocking yarn or tape for outdoor deployment, ensuring minimal attenuation even in sharp bends .

Advantages

• Factory-grade connector quality ensures consistent performance.
• Flexibility to splice into any cable system.
• Time and labor savings compared to field-terminated connectors.
• Reliability in both indoor and outdoor fiber access networks . In summary, a 1-core fiber optic pigtail is a single-fiber solution that combines a pre-terminated connector with a bare fiber for splicing, making it essential for efficient, low-loss fiber network terminations and FTTH deployments .
