EFB Elektronik INFRALAN U-DQ(ZN)BH 24G 50/125µm OM3 LSZH Black CPR-Dca Fiber Optic Cable

The EFB Elektronik INFRALAN U-DQ(ZN)BH 24G 50/125µm OM3 LSZH Black CPR-Dca is a high-performance loose tube fiber optic cable designed for universal indoor/outdoor applications. With 24 multimode fibers (OM3, 50/125µm) and a low smoke zero halogen (LSZH) outer sheath, this cable ensures reliable data transmission with minimal environmental impact. It meets CPR fire class Dca-s2, d2, a1, making it suitable for installations requiring enhanced fire safety.

Advantages

This cable offers excellent attenuation performance (≤2.8 dB/km at 850nm, ≤1.0 dB/km at 1300nm) and high modal bandwidth (1500 MHz·km OFL at 850nm, 2000 MHz·km EMB at 850nm), supporting high-speed data rates over long distances. The LSZH sheath reduces toxic smoke emissions in case of fire, while the non-metallic central strength member and swellable yarns provide rodent protection and UV resistance. Its robust construction ensures durability in harsh environments.

Suitable for

• Indoor/outdoor backbone cabling in data centers, enterprise networks, and telecom installations
• Duct and universal applications requiring fire-rated cables (CPR Dca)
• High-bandwidth applications such as 10 Gigabit Ethernet and beyond
