EFB Elektronik INFRALAN U-DQ(ZN)BH 4G 50/125 OM2 LSZH nero CPR Dca

The EFB Elektronik INFRALAN U-DQ(ZN)BH 4G is a high-quality multimode fiber optic cable designed for universal indoor/outdoor use. With 4 fibers, OM2 grade, and a 50/125 µm core/cladding, it delivers reliable performance for data transmission. The LSZH (Low Smoke Zero Halogen) jacket ensures safety in enclosed spaces, and the CPR Dca-s2, d2, a1 fire classification meets European standards.

Advantages

This cable offers low attenuation (≤2.5 dB/km at 850nm, ≤0.8 dB/km at 1300nm) and high bandwidth (≥500 MHz·km), making it ideal for high-speed networks. Its robust construction with aramid yarns provides excellent tensile strength (1500 N) and crush resistance (1000 N/10cm). The black LSZH jacket is durable and flame-retardant, reducing toxic smoke in case of fire.

Suitable for

• Indoor and outdoor fiber optic installations
• Data centers, LAN backbones, and campus networks
• Applications requiring CPR Dca fire safety compliance
• Environments where low smoke and zero halogen are critical
