Dual-core single-mode fiber optic cable lc

A single-mode dual-core LC fiber optic cable is a duplex 9/125 µm fiber designed for high-speed, long-distance data transmission with LC connectors on both ends.

Overview

A single-mode dual-core fiber optic cable consists of two separate fiber cores (dual-core or duplex) that allow simultaneous bidirectional data transmission, effectively doubling the communication capacity compared to a single-core fiber. The single-mode (SM) designation means the fiber has a small 9-micron core, allowing light to travel in a single, straight path, which minimizes signal loss and supports long-distance transmission . The cladding diameter is typically 125 microns, following industry standards .

LC Connectors

The LC (Lucent Connector) is a small form factor connector with a 1.25mm ceramic ferrule, commonly used in high-density networking environments. LC connectors are available in duplex configurations, meaning two fibers are paired in a single clip for easier installation and management . They are widely used in data centers, telecom networks, and enterprise LANs.

Performance and Applications

• Transmission Distance: Single-mode fibers can transmit data up to 10 km at 1310 nm and 30–40 km at 1550 nm, making them ideal for long-haul and high-speed networks .
• Bandwidth: Supports high-speed Ethernet standards, including 1G, 10G, 40G, 100G, and even 400G connections .
• Cable Jacket: Typically comes with a 2.0–3.0 mm outer diameter, PVC or OFNR-rated jackets, and sometimes zip-cord reinforcement for durability .
• Color Coding: Single-mode cables are usually yellow to distinguish them from multi-mode fibers .

Practical Considerations

• Cable Lengths: Available in custom lengths from 1 meter up to 100 meters or more, depending on the manufacturer .
• Testing and Quality: High-quality single-mode LC duplex cables are tested for attenuation and performance to ensure reliable network uptime .
• Use Cases: Ideal for connecting switches, routers, servers, and optical transceivers in data centers, telecom networks, and enterprise backbone networks. In summary, a single-mode dual-core LC fiber optic cable provides efficient, high-speed, and long-distance data transmission with reliable LC connectors, making it a standard choice for modern networking infrastructure .
