APC single-core pigtail models

APC single-core fiber optic pigtails are available in LC/APC and SC/APC configurations, using single-mode fibers like G652, G655, and G657, designed for low insertion loss and high return loss in PON, CATV, and FTTH networks.OverviewAPC (Angled Physical Contact) pigtails are designed to minimize back reflection and signal interference, making them ideal for analog CATV, bidirectional PON, and high-frequency optical networks. Single-core pigtails typically feature a single fiber terminated with an APC connector on one end and a bare fiber for splicing on the other, allowing seamless integration into patch panels or optical equipment .Common Models and SpecificationsConnector Types: LC/APC and SC/APC are the most common for single-core pigtails. LC/APC connectors are preferred for high-density applications due to their smaller form factor, while SC/APC connectors are widely used in CATV and PON systems .Fiber Types: Single-mode fibers such as G652, G655, and G657 are used, offering low attenuation and stable transmission .Jacket and Diameter: Pigtails are available with 0.9mm or 1.5mm jackets, often LSZH or PVC, providing flexibility and environmental protection .Performance: High-quality APC pigtails achieve insertion loss ≤0.3dB and return loss ≥40dB, ensuring minimal signal reflection and high signal integrity .Color Coding: Single-core pigtails may be color-coded for easy identification in multi-fiber installations, following standard color schemes like blue, green, or orange .ApplicationsPassive Optical Networks (PON): Supports GPON/EPON deployments with minimal reflection for bidirectional traffic .Cable TV (CATV): Ensures clear analog signal transmission with low interference.Fiber-to-the-Home (FTTH): Provides reliable last-mile connectivity for residential and business users.Telecommunication Networks: Suitable for metro and long-haul networks requiring high-frequency, low-reflection links.Advantages of APC over UPCAPC connectors feature an 8° angled polish that directs reflected light away from the fiber core, significantly reducing back reflection compared to UPC connectors. This is critical for analog and bidirectional systems where signal integrity is sensitive to reflections .SummaryAPC single-core pigtails are essential components for high-performance optical networks. They are available in LC/APC and SC/APC types, use single-mode fibers (G652, G655, G657), and provide low insertion loss, high return loss, and environmental stability, making them suitable for PON, CATV, FTTH, and other mission-critical optical applications .
