EFB Elektronik U-DQ(ZN)BH 8E 9/125µm G657A LSZH Black CPR B2ca - Low-Smoke Universal Loose Tube Fiber Optic Cable

The EFB Elektronik U-DQ(ZN)BH 8E is a high-quality universal loose tube fiber optic cable designed for both indoor and outdoor applications. With 8 single-mode fibers (9/125µm) compliant with ITU-T G.657.A bend-insensitive standard, this cable ensures reliable data transmission even in tight installation spaces. The LSZH (Low Smoke Zero Halogen) jacket in black provides enhanced safety by emitting minimal smoke and no toxic halogens in case of fire, making it ideal for use in public buildings, data centers, and industrial environments. Certified to CPR fire class B2ca-s1a, d1, a1, it meets stringent European fire safety regulations.

Advantages

This cable offers exceptional flexibility and durability thanks to its non-metallic strain relief (glass yarn) and loose tube construction. The bend-insensitive fiber design allows for tighter bends without signal loss, simplifying installation in confined spaces. The LSZH jacket ensures compliance with strict fire safety standards, protecting people and equipment. With a wide operating temperature range (-20°C to +70°C) and high tensile strength (1500 N during installation), it is suitable for demanding environments.

Suitable for

• Indoor/outdoor backbone cabling in buildings and campuses
• Data center interconnections requiring bend-insensitive fibers
• Industrial networks where fire safety is critical
• FTTx (Fiber to the x) deployments
• Any installation requiring CPR B2ca compliance
