Indoor Single-Mode Dual-Core Fiber Optic Cable

Indoor two-core single-mode fiber optic cables are designed for high-speed, long-distance data transmission within buildings, supporting applications like FTTH, LAN, and CCTV networks.

Key Features

Fiber Type and Core Size: These cables use single-mode fibers with a core-to-core diameter of 9/125 µm, allowing light to travel directly through the fiber with minimal signal loss, making them ideal for long-distance and high-bandwidth applications . Some variants use bend-insensitive fibers (ITU-T G657A/G652D) for easier installation in tight spaces . Number of Cores: The cable contains two cores, enabling simultaneous transmission of two separate data channels or redundancy for critical networks . Jacket and Protection: Indoor cables typically feature LSZH (Low Smoke Zero Halogen) jackets, which are fire-retardant and safe for indoor environments. Some designs include FRP rods and yarn for added rigidity and durability, facilitating installation in conduits or along walls . Performance: Single-mode design ensures high data transfer rates, low splice loss, and reliable signal integrity. These cables are suitable for FTTH, LAN, inter-building links, and CCTV systems . Form Factor: Options include round cables with an outer diameter around 5.5 mm or flat drop cables for low-friction installation in tight indoor spaces .

Applications

• FTTH/FTTX deployments: Connecting central communication rooms to apartments or offices .
• Local Area Networks (LANs): High-speed data transmission within offices or data centers .
• CCTV and security systems: Reliable video signal transmission over long distances indoors .
• Industrial indoor networks: Supporting critical infrastructure with minimal signal degradation .

Installation Considerations

• Designed specifically for indoor use, these cables are not intended for direct outdoor exposure.
• Flat cables can be stapled to walls or run inside conduits without additional guides, while round cables may require standard cable management .
• Bend-insensitive fibers allow for tight-radius bends without significant signal loss, simplifying installation in confined spaces . Indoor two-core single-mode fiber optic cables provide a compact, durable, and high-performance solution for modern indoor networking needs, ensuring reliable connectivity for both residential and commercial applications .
