6G optical modules typically cost between $50 and $150 per unit, depending on type, distance, and vendor.

Price Ranges by Module Type

• 6G SFP+ LR (Long Reach, 10 km, 1310nm): Available from vendors like FiberMall, these modules are designed for single-mode fiber and can transmit up to 10 km. Prices for such modules generally fall in the $100–$150 range depending on brand and purchase volume .
• 6G SFP+ IR (Intermediate Reach, 2 km, 1310nm): Modules like AscentOptics' SFP-6GSM31-02C support 2 km transmission over single-mode fiber and are considered cost-effective, typically priced around $50–$100 per unit .

Factors Affecting Cost

1. Transmission Distance: Longer reach modules (LR) are more expensive than shorter reach (IR) modules due to higher-quality lasers and optical components.
2. Brand and OEM vs. Compatible Modules: Branded OEM modules often carry a 20–40% premium over aftermarket or compatible modules, reflecting warranty, support, and reliability .
3. Technology and Materials: Costs are influenced by lasers, photodiodes, silicon chips, and precision manufacturing in cleanroom environments .
4. Market Demand and Supply: Legacy modules like 6G SFP+ may fluctuate in price due to lower production volumes and demand for newer high-speed modules (25G, 40G, 100G), which can create temporary scarcity .

Practical Considerations

• Volume Purchases: Buying in bulk can reduce per-unit cost.
• Vendor Selection: Ensure modules are tested and certified to meet SFP+ MSA standards and digital diagnostics functions for reliability .
• Total Cost of Ownership: Consider warranty, support, and replacement ease when comparing prices, as cheaper modules may incur higher operational costs over time . In summary, expect to pay roughly $50–$150 for a 6G SFP+ optical module, with higher prices for long-reach or branded OEM units, and lower prices for short-reach or compatible aftermarket modules.
