SC-FC fiber optic pigtails are short fiber cables with SC and FC connectors pre-terminated on one end, designed for splicing to backbone fibers to ensure low-loss, reliable connections.

Overview

A fiber optic pigtail is a short length of fiber cable with a factory-installed connector on one end and an exposed fiber on the other, intended for fusion or mechanical splicing to a main fiber line. SC-FC pigtails combine SC (Subscriber Connector) and FC (Ferrule Connector) types, allowing flexible connectivity between equipment with different interfaces.

The S

C connector is known for its durable snap-in design, widely used in telecom and data networks, while the FC connector features a screw-on mechanism, providing a secure connection suitable for high-vibration environments.

Types and Specifications

Fiber Mode: Available in single-mode (OS2, 9/125µm) for long-distance, high-bandwidth applications, and multimode (OM1/OM2/OM3/OM4) for shorter distances within buildings or campuses. Polish Types: UPC (Ultra Physical Contact): Standard polish with low back reflection, typically blue connectors.

AP

C (Angled Physical Contact): 8-degree angled polish for superior return loss, typically green connectors, ideal for RF video or high-precision applications. Cable Structure: Tight-buffered for protection, with partial outer jackets to allow flexibility and accommodate tight bend radii. ApplicationsSC-FC pigtails are commonly used in: Data centers and LANs for connecting patch panels and transceivers.

Telecom and CAT

V networks for backbone termination.

FTT

H (Fiber to the Home) and PON networks. Testing and high-vibration environments where FC connectors provide stability. AdvantagesFactory-terminated connectors ensure low insertion loss and high return loss, improving network performance.

Bend-insensitive fibers reduce attenuation when twisted or bent, simplifying installation and maintenance. Compatibility with multiple connector types allows flexible integration into existing networks. Time-saving: Pre-terminated ends reduce field termination errors and installation time.

Installation

The unterminated end of the pigtail is spliced to the main fiber using fusion or mechanical splicing, creating a stable and reliable connection point. SC-FC pigtails can be used in high-density enclosures, with the outer jacket stripped as needed to accommodate tight bends. SC-FC fiber optic pigtails are essential for ensuring high-performance, low-loss connections in modern fiber optic networks, providing both flexibility and reliability for diverse applications.
