Indoor/Outdoor Multi-Loose Tube Fiber Optic Cables

Indoor/outdoor, duct cables suitable for installation in interbuilding and intrabuilding backbones in aerial, duct and riser or plenum applications. The loose tube design offers mechanical ruggedness and environmental durability while the all-dielectric cable construction requires no grounding or bonding. The water-swellable yarn eliminates the need for gel-filling compound and allows more efficient and craft-friendly cable

Applications:

• Suitable for Indoor/ Outdoor Riser, Duct and Arial Installations.
• Telecommunication Networks and FTTH Deployments.
• Datacenter Network Installations.
• Suitable for Risers, vertical shafts or conduits within a building that house essential services and systems.
• Military & Defence Communication Systems.
• Oil & Gas Pipeline Monitoring.
• Rural & Remote Area Broadband Deployment.

Key Features:

• Fiber Compatibility: Supports all telecommunications-grade optical fibers (Singlemode & Multimode).
• UV-Resistant PE Sheath Provides excellent ultraviolet protection, ensuring long-term durability in outdoor environments. Offers high crush resistance and flexibility for rugged duct and aerial installations.
• All-Dielectric Construction Contains no metallic components, making the cable lightweight, non-conductive, and immune to electromagnetic interference (EMI)—ideal for sensitive data transmission zones.
• Lightning Protection The absence of metal significantly reduces the risk of lightning strikes, enhancing safety in aerial and exposed outdoor routes.
• Moisture Resistance Equipped with Water-Blocking Gel or Dry Water-Swellable Tapes, ensuring long-term protection against water ingress without the mess of gel-filled designs—streamlining splicing and installation

Standard:

• IEC 60794-1-2 (Optical fiber cable mechanical & environmental tests).
