INFRALAN U-DQ(ZN)BH OS2 12E (1x12) Eca 3000N LSZH musta, 7,5 mm G657A1 kuitukaapeli 54412D1E-CPR

Fibre optic installations in demanding environments often fail when cables cannot withstand mechanical stress, fire hazards, or tight bends. The INFRALAN U-DQ(ZN)BH OS2 12E cable solves these challenges with a rugged loose-tube design, bend-insensitive G.657.A1 fibres, and a low-smoke zero-halogen sheath.

Who is it for

Network installers and data centre managers who need a reliable single-mode backbone for indoor and outdoor runs, especially where fire safety regulations require LSZH materials and where space constraints demand tight bend tolerance.

Main features

• 12 OS2 single-mode fibres in a loose tube construction
• ITU-T G.657.A1 bend-insensitive fibre reduces signal loss in tight corners
• LSZH black outer sheath for low smoke and zero halogen emissions
• High tensile strength of 3000 N for robust installation
• CPR fire rating Eca for basic fire performance
• UV-resistant and water-blocking for outdoor use

Tips

When pulling this cable, respect the dynamic bend radius of 20 times the diameter (150 mm) to avoid fibre damage. For outdoor installations, ensure proper UV protection at termination points and use watertight enclosures.
