Flame-retardant four-core optical cables typically range from $0.40 to $1.80 per meter, depending on type, construction, and environment.

Price Overview

The cost of a four-core flame-retardant optical cable varies based on several factors, including fiber type (single-mode OS2 or multimode OM3/OM4), jacket material (LSZH, PVC, armored), installation environment (indoor, outdoor, direct burial), and compliance with fire and flame-retardant standards . Typical pricing from suppliers like OWIRE starts at $0.40 per meter for basic indoor LSZH cables and can reach $1.80 per meter for ruggedized outdoor or armored versions designed for harsh conditions . A standard 100-meter reel of single-mode OS2 4-core cable usually costs $60–$90, depending on customization and order volume .

Factors Affecting Price

• Fiber Type: Single-mode OS2 cables for long-distance transmission are generally more expensive than multimode OM3/OM4 cables used for shorter runs .
• Construction: Armored cables with steel tape or additional strength members provide extra protection and cost more than standard LSZH cables .
• Fire and Flame Standards: Compliance with IEC 60331-25 (fire resistance) and IEC 60332-2-3 (flame retardancy) ensures safety in critical environments but can increase cost .
• Environmental Suitability: Outdoor-rated cables with water-blocking gel, UV resistance, and hydrolysis protection are priced higher due to enhanced durability .
• Bulk Orders: Large-volume purchases often qualify for tiered discounts, reducing the per-meter cost for projects exceeding 1,000 meters .

Applications

These cables are widely used in fire alarm systems, voice evacuation networks, public buildings, tunnels, metro systems, and industrial outdoor installations where maintaining communication during fire emergencies is critical . The combination of flame-retardant LSZH sheaths, central strength members, and loose tube design ensures both safety and mechanical reliability.

Summary

For a flame-retardant four-core optical cable, expect a price range of $0.40–$1.80 per meter, with higher costs for armored, outdoor, or single-mode long-distance variants. Bulk orders and supplier-specific discounts can further influence the final cost, while compliance with fire and flame-retardant standards ensures safety and reliability in critical installations .
