Price per kilometer of 4-core optical fiber cable

The cost of one kilometer of 4-core optical fiber cable ranges from approximately $400 to $1,800, depending on type, construction, and environmental rating.

Price Breakdown

• Basic indoor 4-core single-mode OS2 cable: Around $0.40 per meter, totaling roughly $400 per kilometer for standard indoor distribution cables .
• Ruggedized outdoor or armored 4-core single-mode OS2 cable: Prices can reach $1.80 per meter, totaling about $1,800 per kilometer for cables designed for harsh environments, direct burial, or aerial deployment .
• Multimode OM3/OM4 4-core cables: Typically cost less than single-mode for short-distance applications, but prices vary depending on fiber quality and jacket type, generally falling between $0.50 and $1.50 per meter.

Factors Affecting Cost

1. Fiber Type: Single-mode (OS2) is preferred for long-distance transmission and tends to be more expensive than multimode (OM3/OM4) used for shorter runs .
2. Cable Construction: Armored, LSZH (Low Smoke Zero Halogen), or direct burial cables increase the price due to enhanced durability and safety standards .
3. Bulk Purchases: Ordering over 1,000 meters often qualifies for tiered discounts, reducing the per-meter cost .
4. Certifications and Testing: Cables meeting ISO/IEC 11801 or TIA/EIA-568 standards may cost more but ensure lower signal loss and higher reliability .

Additional Considerations

• Installation Costs: The material cost above does not include labor, trenching, splicing, or termination, which can significantly increase total project expenses .
• Long-Term Value: High-quality single-mode cables offer 20–30 years of service life with lower maintenance costs compared to cheaper alternatives . In summary, for a 1 km run of 4-core optical fiber, expect to pay $400–$1,800 for the cable itself, with the final cost depending on fiber type, environmental rating, and bulk purchase discounts.
