EFB Elektronik trunk kábel U-DQ ZN BH OM4 8G 1x8 LC-LC 170m Dca LSZH - 170 m (O8322S170OM4)

Data center technicians and network engineers rely on this EFB Elektronik trunk cable for high-density fiber optic backbone links. The U-DQ ZN BH construction with 8 multimode OM4 fibers in a central loose tube offers a compact, non-metallic solution for structured cabling between distribution areas. Pre-terminated with LC connectors on both ends, the 170-meter length is ideal for spanning large facilities or connecting equipment across floors.

Why choose it

The OM4 fiber supports 10G, 40G, and 100G Ethernet up to 550 meters at 850 nm, making it future-ready for high-speed data center applications. The LSZH jacket and Dca fire rating ensure low smoke and toxic gas emission in case of fire, critical for enclosed spaces. The central loose tube design provides excellent protection against mechanical stress while remaining flexible for installation.

Ideal use cases

• Data center backbone cabling between racks and distribution areas
• Enterprise LAN and SAN infrastructure
• High-density fiber optic links in campus networks

Good to know

The cable is pre-terminated and factory tested, reducing on-site termination time and ensuring consistent performance. The aqua jacket color identifies OM4 multimode fiber per industry standards.
