The price of OM3 multimode fiber typically ranges from $1.50 to $6.00 per foot, depending on core count, quality, and cable type.

OM3 fiber is a 50/125 µm multimode fiber optimized for laser-based equipment, commonly used in high-speed data centers and enterprise networks . It supports 10 Gigabit Ethernet up to 300 meters and can handle 40/100 Gigabit Ethernet up to 100 meters . Large-core OM3 cables, such as those with multiple cores (e.g., 12-core to 96-core), are priced higher due to increased material and manufacturing complexity.

Pricing Details

• Standard OM3 multimode fiber: $1.50 to $6.00 per foot, depending on manufacturer and quality .
• Armored or LSZH (Low Smoke Zero Halogen) cables: $1.15 to $6.50 per meter, offering extra protection against physical damage and fire safety requirements .
• Custom or high-core-count cables: Prices increase with the number of cores, with 96-core or higher cables costing more due to additional glass and jacket materials .

Factors Affecting Price

1. Core Count: More cores increase material costs and complexity.
2. Cable Type: Armored, plenum-rated, or LSZH cables are more expensive than standard PVC-jacketed cables .
3. Brand and Quality: Premium brands like Corning offer lower attenuation and higher reliability, which can increase cost .
4. Length: Prices are usually quoted per meter or per foot, so longer runs proportionally increase total cost .

Where to Buy

OM3 fiber cables are available from electronics distributors like Mouser Electronics, online marketplaces such as Amazon, and specialized fiber suppliers like Fiber4u . Many suppliers offer custom lengths and core counts, allowing you to tailor the cable to your network requirements. In summary, for large-core OM3 optical fiber, expect $1.50–$6.00 per foot for standard cables, with armored or high-core-count options costing more depending on specifications and manufacturer .
