New Zealand Double-Armored Flame-Retardant Optical Cable Models

Double-armored, flame-retardant optical cables in New Zealand include Prysmian Draka FireTuf, YOFC stranded loose tube armored cables, and AFL RIO Wrapping Tube cables, all featuring LSZH sheaths and compliance with fire safety standards.Key Models and Features

1. Prysmian Draka FireTuf

• Available in OM1, OM3, OM4 multimode and OS2 singlemode configurations with 4, 8, 12, or 24 fiber cores .
• Features corrugated steel tape armor for rodent protection and a central loose tube construction.
• Internal and external LSZH sheaths provide low smoke and halogen-free protection.
• Incorporates MaxCap BendBright™ technology for bend-insensitive performance.
• Compliant with IEC 60331-25 fire resistance and IEC 60332-2-3-24C flame retardant standards, suitable for fire alarm, voice alarm, tunnels, and public buildings . 2. YOFC Flame-Retardant Double Armored Stranded Loose Tube Cable
• Fibers housed in high-modulus plastic loose tubes with filling compound, stranded around a metallic central strength member .
• Core armored with laminated aluminum tape and corrugated steel tape, with LSZH inner and outer sheaths.
• Designed for transport/storage temperatures from -40℃ to +70℃ and standard lengths of 2,000m.
• Suitable for indoor/outdoor deployment where mechanical protection and fire safety are critical . 3. AFL RIO Wrapping Tube Cable (WTC) with SpiderWeb Ribbon®
• High-density fiber optic ribbon cable for indoor/outdoor applications .
• Flame-retardant, LSZH-compliant, and riser-rated for building installations.
• Features water-blocking core and bonded fiber ribbon design for efficient splicing.
• Supports high fiber counts (144F to 6912F) and flexible installation in ducts, trays, or covered pathways.
• Engineered for space-constrained, fire-regulated environments .

Considerations for Selection

• Fire safety compliance: Ensure cables meet IEC or local fire standards for flame retardancy and circuit integrity.
• Armor type: Double-armored cables with steel tape and aluminum layers provide superior mechanical protection.
• Fiber type and count: Choose based on network bandwidth requirements and future scalability.
• Environmental suitability: Check for temperature range, UV stability, and indoor/outdoor rating.
• Bend-insensitive technology: Important for tight bends or high-density installations. These models are widely available in New Zealand through distributors of Prysmian, YOFC, and AFL, providing robust, fire-safe solutions for critical infrastructure, public buildings, and industrial networks.
