EFB Elektronik INFRALAN I-B(ZN)BH 12E 9/125 OS2 LSZH Yellow CPR-B2ca

The EFB Elektronik INFRALAN I-B(ZN)BH 12E is a high-quality indoor loose tube fiber optic cable designed for professional network installations. With 12 single-mode fibers (9/125 µm) and OS2 classification, it ensures reliable long-distance data transmission. The cable features a non-metallic central strain relief, LSZH (Low Smoke Zero Halogen) outer sheath in yellow, and meets CPR fire class B2ca-s1a,d1,a1, making it suitable for use in public buildings and areas with strict fire safety requirements.

Advantages

This cable offers excellent attenuation performance (≤0.35 dB/km at 1310nm, ≤0.22 dB/km at 1550nm) and is compatible with ITU-T G.657.A1/A2 and G.652.D standards. Its small diameter (approx. 6.5 mm) and flexible bending radius (15xOD during installation) facilitate easy handling and installation in tight spaces. The LSZH sheath reduces toxic smoke emission in case of fire, enhancing safety.

Suitable for

• Indoor fiber optic backbone cabling in data centers, office buildings, and industrial facilities
• FTTx (Fiber to the x) networks
• LAN and SAN networks requiring high bandwidth and reliability
• Installations where CPR B2ca fire classification is mandatory
