EFB Elektronik INFRALAN U-DQ(ZN)BH 12G 50/125 OM3 LSZH nero CPR Dca

The EFB Elektronik INFRALAN U-DQ(ZN)BH 12G is a high-performance, laser-optimized multimode fiber optic cable designed for demanding data center and enterprise network applications. With 12 fibers, OM3 standard, and a robust loose tube construction with non-metallic strain relief, this cable ensures reliable transmission for 10 Gigabit Ethernet up to 300 meters and supports higher data rates over shorter distances. The black LSZH (Low Smoke Zero Halogen) outer sheath provides enhanced safety in indoor environments, while the CPR Dca-s2, d2, a1 fire classification guarantees compliance with European building regulations.

Advantages

This cable offers exceptional bandwidth and low attenuation, making it ideal for high-speed networks. The LSZH jacket reduces toxic and corrosive gas emissions in case of fire, ensuring safety in occupied spaces. Its universal indoor/outdoor design allows flexible installation, and the non-metallic construction prevents electromagnetic interference.
