Multifiber indoor cables I-F(ZN)H

Indoor cables for permanent installation in cable ducts and conduits

For data center applications, maximizing packing density is essential, while remaining compliant with stringent fire safety requirements. For this purpose, cables with a 4 to 144 fiber count have been developed with a minimal outer diameter. The smaller diameter of our cables makes it possible to improve air circulation in the rack.

  • Cost savings
  • High packing density, small cable design, considerable space savings
  • Direct assembly possible with MPO/MTP connectors
  • CPR-approved cable types
  • Small bending radius
  • Can be worked dry
