SC pigtail fiber is a pre-terminated optical fiber with an SC connector on one end and a bare fiber on the other, available in single-mode or multimode types with various buffer and jacket options.

Overview

An SC pigtail fiber is a short optical fiber cable designed for splicing into a fiber optic network. One end has a factory-terminated SC connector, while the other end is bare for fusion or mechanical splicing to a trunk or distribution cable . The SC connector uses a push-pull mechanism and comes in two main variants:

• SC/APC (Angled Physical Contact): Features an 8° angled ferrule to minimize back reflection (< -60 dB), ideal for FTTH, telecom, and long-distance single-mode applications .
• SC/UPC (Ultra Physical Contact): Provides a flat polish with lower back reflection than standard connectors, commonly used in data centers .

Fiber Types

SC pigtails are available in both single-mode and multimode fibers:

• Single-mode: G652D, G657A2 (bend-insensitive), OS2 for long-distance and FTTH applications .
• Multimode: OM2, OM3, OM4, OM5 for in-building, data center, and short-distance applications .

Buffer and Jacket Options

The fiber can come in different buffer diameters and jackets to match installation requirements:

• Bare fiber: 250 µm for direct splicing .
• Tight-buffered fiber: 900 µm, suitable for splice trays and closures .
• Jacketed minicables: 2.0 mm or 3.0 mm, simplex or duplex (zip-cord) constructions for easier handling and protection .
• Jacket materials: PVC, LSZH (Low Smoke Zero Halogen), armored, or outdoor-rated for environmental protection .

Applications

SC pigtails are widely used in:

• Fiber distribution frames (ODF)
• Splice closures and boxes
• FTTH networks
• Data centers and enterprise backbone cabling
• Industrial fiber optic installations They provide a low-loss, factory-polished connection that ensures consistent optical performance and simplifies field splicing.

Summary

In essence, an SC pigtail fiber is a versatile, pre-terminated fiber solution that bridges factory-polished connectors with field-installed fiber cables. Choosing the correct model involves selecting the connector type (SC/APC or SC/UPC), fiber type (single-mode or multimode), buffer diameter, and jacket type to match your network requirements .
