INFRALAN U-DQ(ZN)BH OS2 24E (1x24) Eca 3000N LSZH Black, 7.5mm G657A1 Fibre Optic Cable 54424D1E-CPR

For data centre technicians and enterprise network installers, this INFRALAN U-DQ(ZN)BH OS2 24E fibre optic cable provides a robust backbone for high-speed, long-distance connections. The cable contains 24 single-mode fibres in a loose tube construction, each compliant with ITU-T G.657.A1 bend-insensitive standards, ensuring reliable performance even in tight routing spaces.

• CPR fire rating: Eca
• Outer diameter: 7.5 mm
• Cable colour: Black
• Tensile strength: 3000 N
• Attenuation: ≤ 0.35 dB/km at 1310 nm, ≤ 0.25 dB/km at 1550 nm
• Minimum bend radius: 10 mm static, 20 mm dynamic
• Operating temperature: -20 °C to +70 °C
• Installation temperature: -5 °C to +50 °C
• UV resistant
• Suitable for indoor and outdoor use

Why choose it

The LSZH sheath reduces toxic smoke and corrosive gas emissions in fire conditions, making it safer for confined spaces. With a 3000 N tensile rating, the cable withstands demanding installation pulls, while the bend-insensitive fibres minimise signal loss when routed around corners.

Ideal use cases

• Backbone cabling in data centres and server rooms
• Long-distance links between buildings on a campus
• High-density fibre distribution in enterprise networks
• Installations requiring CPR Eca compliance

Good to know

The non-metallic construction provides rodent protection and eliminates grounding concerns. The cable is UV resistant, allowing outdoor runs without additional protection. Always follow the specified bend radius to maintain optimal performance.
