This 12-fiber optical cable features twelve 900μm tight-buffered fibers individually color-coded for easy identification. Each fiber is surrounded by aramid yarn strength members and protected by a flame-retardant LSZH jacket. The cable measures 5.6 mm in diameter and weighs 28 kg/km, offering high mechanical robustness with short-term tension of 660 N and crush resistance of 1000 N/100mm. It complies with IEC 60794-1-2 standards for tensile strength, crush, impact, bending, and torsion. Operating temperature ranges from -20°C to +85°C, with bending radius of 10× (unloaded) and 20× (loaded) cable diameter. Available in single-mode (G652D) or multimode configurations. Ideal for indoor backbone cabling, data centers, and high-density installations.
1. High-Density 12-Core Design with Color-Coded Fibers
The cable integrates twelve 900μm tight-buffered fibers, each individually colored (blue, orange, green, etc.) for quick identification during splicing and termination. This 12-core fiber cable saves rack space while supporting high-density interconnections. With a compact 5.6 mm diameter, it reduces conduit congestion.
2. Superior Mechanical Strength with Aramid Yarn Reinforcement
Reinforced by aramid yarn strength members, this LSZH indoor optical cable delivers exceptional pull and crush resistance – short-term tension up to 660 N and crush resistance of 1000 N/100mm. These robust parameters minimize installation damage risks, ensuring long-term reliability in backbone cabling.
3. Flame-Retardant LSZH Jacket for Safe Indoor Use
The flame-retardant LSZH jacket emits low smoke and zero halogen toxins when exposed to fire, meeting strict safety requirements for data centers, server rooms, and public facilities. This tight-buffered indoor cable provides fire protection without compromising flexibility.
4. Excellent Optical Performance with Low Attenuation
Using G652D single-mode fiber, the cable offers attenuation ≤0.35 dB/km at 1310nm and ≤0.21 dB/km at 1550nm, ensuring high signal integrity over long distances. Bending loss is ≤0.05 dB at 1550nm (100 turns, 30mm radius), making it ideal for high-speed networks.
5. Wide Temperature Range & Flexible Bending
The cable operates reliably from -20°C to +85°C (installation down to -40°C storage). With a minimum bending radius of 10× outer diameter (unloaded) and 20× (loaded), it allows easy routing around corners and through cable trays. This 12-core LSZH cable is built for demanding indoor environments.
