Leviton – ADVENTUM Indoor/Outdoor Central Dry Tube Cable Euroclass B2ca

Leviton ADVENTUM Central Dry Tube (CDT) B2ca cables provide 2–24 fibers in a compact, gel‑free central dry tube construction for building backbone and riser installations. Cables use bend‑insensitive fibers (single‑mode and multimode), glass yarn strength members, and a halogen‑free flame retardant low‑smoke (HFFR‑LS) outer sheath. CDT B2ca cables meet EN 13501‑6 Euroclass B2ca and are CE marked for CPR. Suitable for internal/external dry duct and cable tray installations where high life‑safety fire performance is required.

Features and Benefits

• 2–24 fiber counts, color‑coded according to TIA‑598‑D.
• Bend‑insensitive fiber as standard — single‑mode, OM1, OM3, OM4, and OM5 versions.
• Dry water‑blocked central tube prohibits ingress of water throughout the tube length.
• Gel‑free central dry tube construction reduces termination time and removes need for solvents.
• Glass yarn armoring provides high tensile strength and rodent protection.
• Halogen‑Free Flame Retardant Low‑Smoke (HFFR‑LS) sheath (black, UV stable as standard).
• CE marked for CPR; Euroclass B2ca meets requirements of Cca, Dca, and Eca.
• Exceeds relevant mechanical and environmental performance defined by IEC 60794‑2‑20.
