Price of Double-Strand Cable for Optical Fiber

The cost of a 2-strand (duplex) optical fiber cable ranges from approximately $0. 40 to $6 per foot, depending on fiber type, jacket, and installation method.

Retail and Bulk Pricing

For raw duplex singlemode fiber (2 strands, 9/125 µm), retail prices on platforms like Amazon typically start around $0. 40–$1. 50 per foot for standard riser-rated zip cord cables, with bulk purchases offering lower per-foot costs.

Stonewall Cable and similar suppliers allow customization of jacket type (riser, plenum, LSZH), connectors, and optional features, which can increase the price slightly. Pre-terminated or patch cables with connectors are more expensive due to factory termination.

Material Cost Factors

Fiber Type: Singlemode fiber is generally cheaper per foot than multimode fiber, but multimode OM4 or OM5 can cost ~25% more than OM4. Strand Count: A 2-strand cable is at the low end of strand count pricing; higher strand counts increase cost proportionally. Jacket and Construction: Indoor riser-rated cables are less expensive than plenum-rated or armored cables.

Armored or direct-burial cables can range from $0. 50 to $5 per foot depending on environmental protection. Length Discounts: Buying longer reels (e.g., 10,000 ft) can reduce per-foot cost by ~20% compared to 1,000 ft spools.

Installation Considerations

If including installation, costs rise significantly. For example, a 1,000 ft indoor singlemode run with minimal termination may total $2,650–$3,100, while outdoor armored runs with splicing and conduit can reach $11,000–$14,500 for 5,000 ft. Labor, permits, and accessories are major contributors to installed cost.

Summary

Raw 2-strand duplex fiber cable: $0. 40–$1. 50 per foot (singlemode, riser-rated)Armored or plenum cables: $0.

50–$5 per footPre-terminated or patch cables: higher, depending on connectors and factory terminationBulk purchases: can reduce per-foot cost by 20–40% For accurate budgeting, consider fiber type, jacket, strand count, and whether installation is included. Shopping around with multiple suppliers is recommended to get the best pricing for your specific application.
