Fiber optic single-mode dual-core lc-fc

FC-LC single-mode dual-core fiber optic cables are duplex patch cords designed for long-distance, low-loss optical transmission in telecom and data networks.

Overview

FC-LC single-mode duplex cables consist of two optical fibers (dual-core), typically with a 9/125 µm core/cladding diameter, allowing simultaneous bidirectional communication. The FC connector features a round, metal body with screw-threaded coupling, providing high reliability and vibration resistance, while the LC connector has a small form factor with a push-pull latch, ideal for high-density applications in switches, routers, and patch panels .

Key Specifications

• Fiber Type: Single-mode (OS2), optimized for long-distance transmission with low attenuation .
• Core/Cladding Diameter: 9/125 µm.
• Polish Type: UPC (Ultra Physical Contact) for minimal back reflection; APC (Angled Physical Contact) is also available in some variants .
• Cable Jacket: Options include PVC, LSZH (Low Smoke Zero Halogen), plenum-rated, or riser-rated, depending on installation requirements .
• Cable Diameter: Typically 2.0 mm for tight-buffered cables.
• Duplex Configuration: Two fibers in a single cable, often color-coded for easy identification.

Applications

• Telecommunications networks for long-haul or metro fiber links.
• Data centers for high-speed connections between switches, routers, and servers.
• Optical distribution frames (ODFs) and patch panels.
• High-performance fiber-optic networks requiring low insertion loss and high return loss .

Advantages

• Low insertion loss and return loss, ensuring efficient signal transmission.
• High reliability under multiple mating cycles due to robust FC and LC connectors.
• Compact and versatile, suitable for high-density installations.
• Customizable lengths from 0.2 m to over 50 m, with same-day shipping available from suppliers .

Purchasing Options

Suppliers like Optcore, Thorlabs, FS.com, and ShowMeCables offer FC-LC single-mode duplex cables with various lengths, jacket materials, and polish types. Some models are end-of-sale but replaced with updated versions, ensuring continued availability . In summary, FC-LC single-mode dual-core fiber optic cables are ideal for reliable, long-distance optical communication, combining the ruggedness of FC connectors with the compact LC form factor for high-density network environments.
