EFB Elektronik INFRALAN U-DQ(ZN)BH 4x12E 9/125µm G.652D LSZH Black CPR Eca Universal Loose Tube Fiber Optic Cable

The EFB Elektronik INFRALAN U-DQ(ZN)BH is a high-quality universal loose tube fiber optic cable designed for indoor and outdoor use. With 48 single-mode fibers (4 tubes x 12 fibers) and a 9/125 µm core/cladding, it meets ITU-T G.652.D standards for excellent optical performance. The black LSZH (Low Smoke Zero Halogen) sheath ensures safety in confined spaces, and the CPR Eca classification confirms its fire performance. Ideal for backbone installations, data centers, and campus networks.

Advantages

This cable offers low attenuation (≤0.35 dB/km at 1310nm, ≤0.22 dB/km at 1550nm), high tensile strength (1500 N during installation), and a robust construction with non-metallic strain relief and glass yarn armouring. Its dry-filled loose tube design prevents water ingress while maintaining flexibility. The LSZH material reduces toxic smoke in case of fire, making it suitable for public buildings and tunnels.
