The cost of a 2-kilometer optical cable ranges from approximately $600 to $12,000 depending on fiber type, strand count, and construction.

Estimated Material Costs

Fiber optic cable prices vary widely based on specifications:

• Single-mode fiber (9/125 µm): $0.10 to $0.50 per foot for standard cables, translating to roughly $656 to $3,280 for 2 km (6,561 feet) if purchased as raw cable materials .
• Multimode fiber (50/62.5 µm): $0.30 to $1.00 per foot, which would cost approximately $1,968 to $6,561 for 2 km .
• High-strand-count or armored cables: Can reach $5–$6 per foot, potentially costing $32,805 to $39,366 for 2 km . Wholesale bulk purchases may reduce costs by 20–40%, while retail or pre-terminated cables are generally more expensive .

Specific 2 km Cable Listings

• OTDR launch cable (2 km, single-mode, G652D): Available on Amazon, typically sold as bare fiber or pre-connectorized, with prices varying based on connector type and polish method .
• Alibaba listings: Offer 2 km optical cables for long-distance applications, including single-mode and multimode options, with prices depending on fiber type, environmental protection (armored or outdoor-rated), and bandwidth requirements .

Factors Affecting Price

1. Fiber Type: Single-mode is cheaper per foot but requires more expensive transceivers; multimode is costlier per foot but cheaper equipment.
2. Strand Count: More strands increase cost proportionally.
3. Cable Construction: Armored or plenum-rated cables for harsh environments are more expensive.
4. Installation: Underground or direct-burial installation adds significant cost beyond the cable itself.

Practical Considerations

For a 2 km run, single-mode fiber is generally recommended for long-distance, high-bandwidth applications. If purchasing pre-terminated or armored cables, expect the higher end of the price range. For bulk raw cable purchases, contacting manufacturers or distributors directly can yield better pricing. In summary, a 2 km optical cable can cost anywhere from around $600 for basic single-mode fiber to over $12,000 for high-strand-count, armored, or pre-terminated cables, depending on specifications and purchase method .
