EFB Electronics U-DQ(ZN)BH 48G 50/125 OM4 LSZH μαύρο CPR-B2CA - Low-Smoke

The EFB Electronics U-DQ(ZN)BH 48G is a high-performance loose tube multimode fiber optic cable designed for demanding indoor installations. With 48 fibers of OM4 grade, it delivers exceptional bandwidth and low attenuation for high-speed data transmission. The cable features a black LSZH (Low Smoke Zero Halogen) sheath, ensuring safety in confined spaces by emitting minimal smoke and no toxic halogens in case of fire. Compliant with CPR fire class B2ca-s1a,d1,a1, it meets stringent European building regulations. Ideal for data centers, enterprise networks, and backbone cabling, this cable provides reliable performance and easy installation.

Advantages

High fiber count (48 fibers) in a compact design saves space and simplifies cable management. OM4 grade supports 40G and 100G Ethernet over longer distances. LSZH sheath enhances safety in public and commercial buildings. CPR B2ca certification ensures compliance with EU construction standards.

Suitable for

• Data center backbone cabling
• Enterprise local area networks (LANs)
• High-speed network infrastructure (10G, 40G, 100G)
