U-DQ(ZN)BH 250
TECHNICAL DATA SHEET
Universal Fibre Optic Cable | Singlemode & Multimode | Indoor/Outdoor | Black LSZH | CPR Eca
U-DQ(ZN)BH 250 is a metal-free fibre optic cable designed for indoor and outdoor data communication and telecommunications networks.
The cable features optical fibres arranged in gel-filled loose tubes, non-metallic glass yarn reinforcement and a black low-smoke zero-halogen (LSZH) outer sheath.
Multi-loose-tube versions incorporate a central FRP strength member and water-blocking materials.
Available fibre types include G.652D, G.657A1, OM1, OM2, OM3 and OM4. The cable is suitable for indoor installation and outdoor installation in empty conduits.
CPR classification: Eca.
