DLC optical cable

DLC refers to a type of fiber optic connector and patch cord used in telecommunications, particularly for connecting base station equipment.

What is DLC?

DLC (Dual LC) is a fiber optic connector type where both ends of the cable are terminated with LC connectors, which are small form-factor connectors commonly used in high-density network applications . DLC patch cords are designed for single-mode or multi-mode fibers and are widely used in Fiber to the Antenna (FTTA) setups, base stations, and other telecom infrastructure .

Key Features

• Connector Type: LC connectors on both ends (DLC/DLC), available in PC, UPC, or APC polish types .
• Fiber Types: Single-mode (G652D, G657A) and multi-mode (OM1, OM2, OM3, OM4) fibers .
• Cable Jacket: Options include PVC, LSZH (Low Smoke Zero Halogen), or outdoor UV-resistant jackets .
• Durability: Many DLC cables are water-blocked, flexible, and UV-resistant, suitable for outdoor deployment .
• Standards Compliance: Designed according to Telcordia GR-326-CORE, IEC 874-1, ANSI/TIA-568-C.3, ISO/IEC 11801, and UL94V-0 .

Applications

• Telecommunication Base Stations: DLC cables are used to connect radio units to baseband units, supporting high-speed data transmission .
• Outdoor Fiber Assemblies: Armored or protected DLC cables are used in outdoor environments, providing resistance to water, UV, and mechanical stress .
• High-Density Networks: Their small form factor allows for efficient space utilization in patch panels and network racks .

Advantages

• Compact and High-Density: LC connectors are smaller than SC or ST, allowing more connections in limited space.
• Reliable Performance: High concentricity ferrules and precise alignment ensure low insertion loss and high return loss.
• Customizable: Lengths, fiber types, and jacket materials can be tailored for specific network requirements . In summary, DLC on optical cables refers to dual LC connector patch cords that are essential for modern telecom networks, offering compact, reliable, and flexible solutions for both indoor and outdoor fiber optic deployments .
