Multimode indoor optical fiber cable typically costs between $2.50 and $5.50 per foot, depending on fiber type, strand count, and jacket rating.

Price Ranges by Fiber Type and Rating

• OM1 Multimode: Generally the most affordable, with riser-rated indoor cables priced around $3.23 to $3.43 per foot for standard 12-strand configurations .
• OM3 Multimode: Designed for higher performance over longer distances, costs range from $3.28 to $4.50 per foot, with riser and plenum-rated options affecting the price .
• OM4 Multimode: Offers superior performance and future-proofing, typically priced $4.50 to $5.50 per foot for standard indoor ratings, and can reach $13.50 per foot for armored or specialized applications .

Factors Affecting Cost

1. Fiber Count: Higher strand counts increase costs proportionally. For example, a 24-strand cable costs roughly twice as much as a 12-strand cable .
2. Jacket and Construction: Indoor riser-rated (CMR) cables are cheaper than plenum-rated (CMP) cables due to fire safety requirements. Armored cables for harsh environments or direct burial add significantly to the price .
3. Cable Length and Bulk Purchase: Buying longer reels (e.g., 10,000 ft) can reduce the per-foot cost by approximately 20% compared to shorter lengths .
4. Installation Environment: Indoor ceiling or riser installations are less expensive than outdoor or underground runs, which may require conduit, trenching, or directional boring .

Additional Considerations

• Pre-terminated assemblies and patch cables cost more due to factory termination and connector type .
• Long-term value: While multimode fiber is more expensive per foot than single-mode fiber, it often reduces total link costs because transceivers are cheaper and installation is simpler for short-distance indoor networks .
• Regional pricing: Costs can vary by region, with the Midwest generally lower than the Northeast or West Coast in the U.S. . In summary, for indoor multimode fiber optic cable, expect to pay $2.50–$5.50 per foot for standard riser or plenum-rated cables, with higher-end armored or specialized cables costing significantly more. Matching the fiber type and rating to your network requirements can optimize both performance and budget .
