This single-core tight-buffered optical cable features a 900μm fiber surrounded by aramid yarn strength members and a flame-retardant LSZH jacket. The compact 3.0 mm diameter and lightweight 7 kg/km design make it ideal for indoor patching and short-haul applications. It offers short-term tensile strength of 150 N and crush resistance of 500 N/100mm, ensuring reliable handling during installation. The cable uses G.652D single-mode fiber with low attenuation (≤0.35 dB/km at 1310 nm, ≤0.21 dB/km at 1550 nm) and operates from -20 °C to +85 °C. Compliant with IEC standards for tensile, crush, impact, and bending tests, this cable is perfect for data center patching, optical distribution frames, and FTTH terminal connections where fire safety and mechanical robustness are required.
1. Compact and Lightweight Design for High-Density Patching
With an outer diameter of only 3.0 mm and a weight of 7 kg/km, this cable is exceptionally slim and light. It allows high-density routing in crowded patch panels, cable trays, and data center cabinets. The small footprint reduces airflow blockage and simplifies cable management, enabling technicians to install more fibers in the same space without compromising cooling or accessibility.
2. Robust Mechanical Protection with Aramid Yarn Strength Members
The cable features aramid yarn strength members, providing short-term tensile strength of 150 N and crush resistance of 500 N/100mm. This ensures the fiber remains protected during pulling, bending, and everyday handling. The aramid yarn also offers excellent cut-through resistance, preventing accidental damage from sharp edges in cable management systems. These mechanical properties guarantee reliable performance throughout installation and long-term use.
3. Flame-Retardant LSZH Jacket for Indoor Fire Safety
The LSZH (Low Smoke Zero Halogen) jacket emits minimal toxic smoke and no corrosive halogens when exposed to fire, meeting strict safety standards for indoor environments. It is ideal for data centers, schools, hospitals, and public buildings where human safety and equipment protection are critical. The jacket also resists UV and aging, ensuring long-term durability even in demanding indoor settings.
4. Excellent Optical Performance with G.652D Single-Mode Fiber
The cable utilizes G.652D single-mode fiber, offering attenuation ≤0.35 dB/km at 1310 nm and ≤0.21 dB/km at 1550 nm. It supports long-distance transmission with low bending loss (≤0.05 dB at 1550 nm over 100 turns, 30 mm radius). The tight-buffered construction prevents micro-bends, ensuring stable signal integrity for high-speed networks, FTTH, and backbone applications.
5. Wide Operating Temperature and Flexible Bending Radius
The cable operates from -20 °C to +85 °C and can be installed between -10 °C and +70 °C, accommodating various indoor climates. The minimum bending radius is 10× cable diameter (unloaded) and 20× (loaded), allowing flexible routing around corners and through tight spaces. This combination of thermal resilience and bendability makes it suitable for both equipment rooms and outdoor termination enclosures.
