Indoor Six-Core Single-Mode Fiber Optic Cable

Indoor six-core single-mode fiber optic cables are tight-buffered, low-smoke, flame-retardant cables designed for reliable indoor data transmission and easy termination.

Cable Construction and Specifications

Indoor six-core single-mode fiber optic cables typically feature six 9/125 µm single-mode fibers with a 900 µm tight buffer for protection and ease of handling during installation. The fibers are made of high-purity silica with germanium doping, coated with a UV-curable acrylate primary protective layer. The cable often includes aramid yarn strength members for tensile strength and durability, and a low-smoke zero-halogen (LSZH) jacket to meet fire safety standards in indoor environments.

Typical outer diameters range from 4. 8 mm to 5 mm, with a lightweight design around 17. 5 kg/km.

Key FeaturesTight-buffered design: Facilitates easier termination and splicing, ideal for low-fiber-count applications in LANs or intra-building backbones. Plenum or riser rated: Suitable for installation in air-handling spaces or vertical shafts, providing low-smoke and flame-retardant properties. Durable jacket: Protects fibers during installation and in rugged indoor environments, often with color-coded fibers for easy identification.

Bend radius and flexibility: Small diameter and tight-buffered construction allow installation in space-constrained areas without compromising performance.

Applications

Indoor six-core single-mode fiber optic cables are commonly used for: Intra-building backbones connecting multiple floors or departments. Headend termination to fiber backbones in enterprise networks. Fiber rack systems and multi-floor deployments where selected fibers are used per floor.

LA

N and data center installations requiring high-speed, low-loss single-mode transmission.

Performance Considerations

Attenuation: Single-mode fibers provide low signal loss over long distances, typically around 0. 35 dB/km at 1310 nm and 0. 22 dB/km at 1550 nm depending on manufacturer specifications.

Ease of termination: Tight-buffered fibers allow direct termination without fan-out kits, simplifying installation in patch panels or wall outlets. Environmental protection: LSZH jackets and aramid yarns ensure safety and mechanical strength in indoor environments. In summary, indoor six-core single-mode fiber optic cables are high-performance, safe, and easy-to-install solutions for enterprise, industrial, and multi-floor indoor network deployments, offering reliable data transmission and compliance with fire safety standards.
