Optical data cable GDX501 series

low-smokeflame-retardantindoor/outdoor

Product Application
The central tube (center-beam) glass-fiber indoor/outdoor universal optical cable GDX501 uses a loose-tube design with color-coded fibers inside the tubes. The cable core is wrapped with water-blocking yarn, reinforced by glass-fiber rod (FRP), and extruded with an FRNC/LS0H outer sheath. The construction combines indoor flame-retardant requirements with outdoor water-blocking capability to allow continuous indoor-to-outdoor routing where both properties are required. The cable is manufactured to meet relevant structured cabling and optical fiber standards (ISO/IEC 11801, GB 50311) and optical/mechanical standards (ANSI/TIA-568.3-D, IEC 60794, YD/T 1770). Fiber types comply with ITU-T G.652.D and G.657 requirements.

Product Features

• Non-metallic glass-fiber strength members and central FRP for axial strength and geometry stability.
• FRNC/LS0H jacket for low smoke and halogen-free flame performance in indoor areas; gel-filled loose tube and water-blocking yarn for outdoor moisture protection.
• Simplified structure for straightforward installation in mixed indoor/outdoor runs.

Product Performance

• Allowable tensile force: Long-term 200 N; Short-term 600 N
• Allowable crush force: Long-term 300 N/100 mm; Short-term 1000 N/100 mm
• Bending radius: Dynamic 20 × D; Static 10 × D
• Ambient temperature: Storage/transport/use -40 °C to +70 °C; Installation -15 °C to +50 °C

Technical highlights

• FRNC/LS0H jacket: flame-retardant, low smoke, halogen-free for compliance with indoor fire safety rules.
• Central FRP (glass-fiber rod) provides axial strength and reduces microbending under tension.
• Non-metallic glass-fiber yarns as strength members avoid EMI and grounding concerns.
• Gel-filled loose tube and water-blocking yarn provide moisture protection and fiber cushioning.
• Available in single-mode and multimode variants (G.652.D, OM2, OM3, OM4) with 2–24 cores.

Product Advantages

• Central-tube geometry improves bending resistance and ensures more uniform stress distribution on bends.
• Non-metallic construction enables direct indoor introduction from outdoor runs without metallic bonding.
• Halogen-free flame performance combined with outdoor water-blocking allows use in buildings with strict fire codes and exterior runs.

Use Scenarios

• Campus and municipal networks requiring continuous indoor/outdoor cabling (surveillance, backbone links).
• Commercial buildings and retail complexes where indoor fire codes and outdoor durability are both required.
• Temporary venues and event networks requiring rapid, EMI-free routing across indoor and outdoor zones.
