EFB Elektronik U-DQ(ZN)BH 48E 9/125µm G.657.A LSZH čierny CPR-B2ca nízkodymový optický kábel

Single-mode fiber optic cable with 48 bend-insensitive G.657.A fibers in a black LSZH sheath, engineered for universal indoor/outdoor use and certified CPR B2ca for low fire hazard. The non-metallic construction with glass yarn strain relief ensures fully dielectric operation, making it ideal for installations near power lines or in lightning-prone areas.

Advantages

The bend-insensitive G.657.A fibers allow tight bends without significant signal loss, simplifying installation in confined spaces. The LSZH jacket emits low smoke and zero halogen when exposed to fire, enhancing safety in populated buildings. With a CPR classification of B2ca-s1a,d1,a1, this cable meets stringent European fire safety regulations, reducing risk and liability. The fully dielectric design eliminates grounding requirements and provides immunity to electromagnetic interference, ensuring reliable data transmission.
