One 24-core indoor single-mode optical cable

A 24-core indoor single-mode optical cable is a tight-buffered, multi-core fiber cable designed for indoor distribution, offering high-performance single-mode transmission with low-smoke, flame-retardant jackets.

Key Specifications

Fiber Type: Single-mode (SM), typically 9/125 µm core/cladding diameter, optimized for long-distance, low-loss transmission. Number of Cores: 24 individual fibers, often arranged in tight-buffered tubes for easy handling and termination. Buffering: 900 µm tight buffer for mechanical protection and simplified installation.

Strength Members: Aramid yarn (Kevlar) for tensile strength and durability during installation. Jacket Material: Options include LSZH (Low Smoke Zero Halogen) for plenum or riser spaces, or PVC for standard indoor use. Outer Diameter: Typically ranges from 7.

2 mm to 8 mm depending on construction and jacket type. Flame and Smoke Ratings: Plenum-rated cables meet NFPA standards for low smoke and flame propagation; LSZH jackets reduce toxic gas emission in case of fire. Bend Radius: Minimum static bend radius is usually 5 times the cable diameter when using G.

657 fibers, allowing flexible routing in tight spaces. Construction FeaturesTight-Buffered Design: Each fiber is individually coated and protected, facilitating direct termination without additional pigtails or transition boxes.

Multi-

Core Arrangement: Fibers are grouped in tubes or bundles, providing organized distribution for multi-floor or intra-building backbones. Mechanical Protection: Nylon or reinforced jackets provide tear resistance and ease of pulling during installation.

Indoor/

Outdoor Compatibility: Some cables can be upgraded to indoor/outdoor versions without changing core characteristics, suitable for building entry points.

Applications

Indoor Backbone Cabling: Connecting equipment racks, patch panels, and distribution frames within buildings.

Multi-

Floor Deployments: Select fibers can be routed to each floor for structured cabling systems. Data Centers and Headends: High-density fiber distribution for network backbones and server connections. Plenum Spaces: LSZH or plenum-rated cables are suitable for air-handling spaces where fire safety is critical.

Advantages

High Transmission Performance: Single-mode fibers support long-distance, high-bandwidth applications. Ease of Installation: Tight-buffered fibers simplify termination and reduce the need for additional protective components. Safety and Compliance: LSZH and plenum-rated jackets ensure compliance with fire safety regulations.

Durability: Aramid yarn and reinforced jackets provide mechanical strength and resistance to pulling or bending stresses. In summary, a 24-core indoor single-mode optical cable is a versatile, high-performance solution for indoor fiber optic networks, offering organized multi-core distribution, mechanical protection, and compliance with fire safety standards, making it ideal for structured cabling, data centers, and multi-floor building installations.
