ETK Kablo Fire-Resistant Fiber Optic CablesStandards: CPR B2ca, FE180 fire-resistanceFeatures: Low smoke, zero halogen, flame retardantApplications: Tunnels, hospitals, airports, industrial plants, data centers, railway networksBenefits: Maintains optical signal integrity under extreme heat, mechanical durability, global compliance with EU and international safety codes 4. APAR Fire Survival Optical CablesFiber Types: G652.D, G657.A, G655 singlemode; OM1, OM2, OM3, OM4 multimodeCore Counts: 2F to 512FConstruction: Gel-filled loose tubes around central strength member, steel wire or corrugated steel tape armor, LSZH sheathFire Resistance: Operates for 3 hours at 750°CApplications: Fire alarm systems, voice evacuation, public buildings, tunnels, metro linesFeatures: Halogen-free, flame retardant, UV and weather resistant, chemical resistant to diesel, petrol, glycol, ethanol, and oils SummaryThese flame-retardant armored optical cables are designed to ensure continuous operation during fire events, protect fibers mechanically, and comply with international fire and safety standards. Selection depends on fiber type, core count, installation environment, and required fire-resistance rating. For critical infrastructure, cables with LSZH sheaths, steel armor, and compliance with IEC 60331-25 or CPR B2ca standards are recommended to maintain both safety and data integrity. These models are suitable for industrial, public, and marine applications, providing reliable performance in high-risk environments while minimizing smoke and halogen emissions during fire exposure.
