EFB Elektronik INFRALAN I-B(ZN)BH 4x12E 9/125µm OS2 LSZH giallo CPR-B2ca

The EFB Elektronik INFRALAN I-B(ZN)BH 4x12E is a high-performance indoor fiber optic cable designed for reliable single-mode transmission. With 48 fibers arranged in 4 loose tubes of 12 fibers each, this cable meets OS2 standards and features a 9/125 µm core/cladding diameter. The LSZH (Low Smoke Zero Halogen) sheath ensures safety in indoor environments, while the yellow color provides easy identification. Compliant with CPR class B2ca-s1a,d1,a1, it is suitable for building infrastructure.

Advantages

This cable offers low attenuation (≤0.35 dB/km at 1310 nm and ≤0.22 dB/km at 1550 nm), ensuring excellent signal integrity over long distances. Its fully dielectric construction eliminates the need for grounding, simplifying installation. The central non-metallic strength member provides robust tensile strength while maintaining flexibility. LSZH material reduces toxic smoke emission in case of fire, enhancing safety.

Suitable for

• Indoor backbone cabling in data centers and enterprise networks
• FTTx (Fiber to the x) applications
• Building riser and horizontal cabling
• High-speed data transmission up to 100 Gbps and beyond
