LC Pigtail Fiber Optic Connector Overview

The LC pigtail is a widely used fiber optic connector in modern telecommunications and data networks. Known for its compact design and high performance, this connector type has become a popular choice for various applications.

What is an LC Pigtail?

An LC pigtail is a short fiber optic cable with an LC connector pre-installed on one end and unterminated fibers on the other. The “pigtail” refers to the unterminated end that is typically spliced or connected to other fiber optic components in a network installation.

Key Features of LC Pigtails

LC pigtails offer several distinctive features that make them advantageous for fiber optic installations:

• Small Form Factor: The LC connector is approximately half the size of traditional SC connectors
• Push-Pull Mechanism: Easy to connect and disconnect with a secure latch
• Low Insertion Loss: Typically less than 0.3 dB for high-quality connectors
• High Return Loss: Often exceeding 50 dB for UPC connectors
• Dual LC Option: Available in single or duplex configurations

Common Applications

LC pigtails are used in various scenarios including:

• Fiber distribution frames
• Patch panels
• Fiber optic terminal boxes
• Data center interconnections
• Telecommunication networks

Types of LC Pigtails

LC pigtails come in several variations to meet different network requirements:

• Single-mode LC Pigtails: Designed for long-distance transmission with 9/125μm fibers
• Multimode LC Pigtails: Used for short-distance applications with 50/125μm or 62.5/125μm fibers
• UPC vs APC Polish: Available with Ultra Physical Contact (blue connector) or Angled Physical Contact (green connector) polish
• Armored Pigtails: Feature additional protection for harsh environments

Installation Considerations

When working with LC pigtails, several factors should be considered:

• Proper fiber preparation and cleaning
• Correct fusion splicing techniques
• Adequate bend radius management
• Proper strain relief
• Labeling and documentation

The LC pigtail continues to be a fundamental component in fiber optic networks, offering reliability, performance, and flexibility for various installation scenarios. Its compact size and excellent optical characteristics make it particularly suitable for high-density applications in modern data centers and telecommunications infrastructure.
