Fiber optic pigtail SC to FC

An FC-SC fiber optic pigtail is a short fiber cable with an FC connector on one end and an SC connector on the other, designed for splicing and connecting optical networks with minimal loss.

Overview

A fiber optic pigtail is a short length of fiber cable with a factory-installed connector on one end and a bare fiber on the other, intended for fusion or mechanical splicing to a trunk fiber or patch panel. In the case of an FC-SC pigtail, the FC connector provides a secure screw-on connection, ideal for high-vibration environments or testing equipment, while the SC connector offers a simple, durable snap-in design commonly used in telecom and data applications .

Key Features

• Connector Types: FC (screw-on) and SC (snap-in)
• Fiber Modes: Available in single-mode (OS2, 9/125µm) for long-distance, high-bandwidth applications, and multimode (OM1–OM4) for shorter distances
• Polish Types: UPC (Ultra Physical Contact) or APC (Angled Physical Contact) to reduce return loss
• Cable Structure: Typically 0.9mm tight-buffered fiber, sometimes with partial outer jackets for protection and bend radius management
• Lengths: Standard lengths include 1m, 1.5m, and 2m, with options for custom lengths and bundled color-coded sets for patch panels

Applications

• Splicing: Connects a pre-terminated fiber to a trunk cable via fusion or mechanical splicing
• Patch Panels and ODFs: SC end plugs into patch panels or transceivers, while FC end ensures secure connection in high-vibration or testing setups
• FTTH/FTTx Networks: Used in fiber access terminals, splitter boxes, and distribution panels for efficient network deployment
• Telecom and Data Centers: Provides reliable, low-loss connections for high-density installations

Performance

• Insertion Loss: Typically ≤ 0.3 dB
• Return Loss: ≥ 50 dB for UPC, ≥ 60 dB for APC
• Factory Testing: Each pigtail is tested to ensure minimal signal attenuation and high-quality connections

Advantages

• Eliminates the need for field polishing, ensuring factory-grade connector quality
• Reduces installation time and improves accuracy
• Compatible with a wide range of network equipment and optical devices
• Supports high-density and organized fiber management with color-coded bundles In summary, an FC-SC fiber optic pigtail is a versatile and reliable component for connecting and splicing fiber networks, combining the secure FC connector with the widely used SC connector to meet diverse network requirements while maintaining low loss and high performance .
