EFB Elektronik U-DQ(ZN)BH 24E 9/125µm G657A LSZH Black CPR B2ca - Low-Smoke Universal Fiber Optic Cable

The EFB Elektronik U-DQ(ZN)BH 24E is a high-performance universal fiber optic cable designed for indoor and outdoor applications. With 24 single-mode fibers (OS2) featuring bend-insensitive G.657.A technology, this cable ensures reliable data transmission even in tight installation spaces. The LSZH (Low Smoke Zero Halogen) sheath in black provides enhanced safety in case of fire, while the CPR B2ca classification guarantees compliance with European fire safety standards. Ideal for backbone cabling, data centers, and FTTH networks.

Advantages

Bend-insensitive fibers reduce signal loss during installation and operation. Dry water-blocking technology eliminates the need for gels, making installation cleaner and faster. The robust construction with aramid yarn strain relief ensures durability and long service life.
