Models and Specifications of Flame-Retardant Optical Cables for Telecommunications

Flame-retardant optical cables are designed with specialized sheathing, armoring, and materials to maintain communication integrity during fire, with models varying by structure, fire-resistance rating, and application environment. Key Models and DesignsFLOWGUARD™ Fire-Resistant Optical Cables These cables feature reinforced plastic (FRP) armoring for flexibility, low bending radius, and rodent protection. They are waterproof, operate across wide temperature ranges, and support up to 12 fibers per bundle, making them suitable for indoor and outdoor communication networks.

Ceramic Sheathing Flame-

Retardant Cables Developed with a cable core wrapped in two-sided synthetic mica tape, an inner sheath packed with ceramic sheathing materials, steel wire armor, and an LSZH outer sheath. These cables achieve high flame resistance, with LOI up to 40% and temperature index up to 370°C. They maintain optical fiber attenuation under extreme fire conditions (up to 950°C) and comply with IEC60332 and BS6387 standards, ideal for subways, tunnels, and rail transport.

APA

R Fire-Resistant/Survival Cables These cables use steel wire braiding or corrugated steel tape armor, with fibers in gel-filled loose tubes around a central strength member. They are LSZH and FR-sheathed, supporting single-mode (G652. D, G657 A, G655) and multi-mode (OM1–OM4) fibers.

They ensure operation for up to 3 hours in fires up to 750°C, suitable for emergency communication systems in public buildings, tunnels, and metro lines.

ETK Kablo B2ca-

Classified Cables Certified to B2ca CPR and FE180 standards, these cables maintain optical integrity under extreme heat and flame. They provide low smoke emission, zero halogen content, and mechanical durability, suitable for tunnels, hospitals, airports, industrial plants, and data centers. B2ca classification ensures very high fire performance with limited heat release and flame spread.

Stainless Steel Wrinkled Optical Unit Cables This model incorporates a stainless steel wrinkled optical unit filled with waterproof fiber pastes, offering compact structure, small diameter, and light weight. It provides flame retardancy, fire resistance, cold resistance, ozone and chemical resistance, low-temperature flexibility, and heat stability, suitable for communication and data transmission in harsh environments.
