Pigtail Single Mode Dual Core Round Head APC

A Pigtail Single Mode Dual Core Round Head APC is a high-performance fiber optic pigtail with an angled physical contact connector, designed for low-loss, long-distance single-mode applications.

Overview

A fiber optic pigtail is a short length of optical fiber with a pre-terminated connector on one end and a bare fiber on the other, intended for fusion or mechanical splicing to backbone cables or multi-fiber trunks . The single-mode designation (OS2) indicates a 9/125µm core, optimized for long-distance, high-bandwidth transmission . The dual-core round head APC refers to the connector type and polish:

• APC (Angled Physical Contact): The fiber end-face is polished at an 8° angle, which minimizes back reflection and improves signal integrity, making it ideal for FTTH, telecom, and RF video applications .
• Round head: The connector ferrule has a circular design, compatible with standard SC, LC, or other connector housings.
• Dual-core: Typically indicates the pigtail can accommodate two fibers in a single assembly, useful for duplex transmission or redundancy.

Key Features

• Low insertion loss and high return loss due to factory-polished APC connectors .
• Pre-terminated and tested for end-face quality, insertion loss (IL), and return loss (RL), ensuring reliable performance .
• Flexible jacket options: LSZH (Low Smoke Zero Halogen) or standard PVC for safety and environmental compliance .
• Compatibility: Works with SC/APC, LC/APC, or other connector types depending on network requirements .

Applications

• FTTH (Fiber to the Home) deployments for high-speed broadband .
• Telecom and data center networks requiring low-reflection, long-distance single-mode connections .
• Backbone and trunk cable termination in patch panels or enclosures.
• Fusion splicing to connect bare fibers to pre-terminated components, ensuring a clean, low-loss signal path .

Advantages

• Superior optical performance compared to field-terminated connectors.
• Reliable and consistent quality due to factory termination and polishing.
• Reduces network downtime by providing a ready-to-use, high-quality connection point.
• Supports duplex or dual-fiber applications with dual-core configurations. Choosing a Pigtail Single Mode Dual Core Round Head APC ensures high-speed, long-range, and low-reflection performance, making it a preferred choice for professional fiber optic installations .
