QSFP-DD Optical Module Smart FOB Price

Smartoptics QSFP-DD modules typically range from $1,400 to $1,800 for 400G short-reach modules, with higher-end coherent or long-haul modules costing significantly more. Price OverviewQSFP-DD (Quad Small Form-Factor Pluggable Double Density) modules vary widely in price depending on type, reach, and vendor. For 400G short-reach SR8 modules, which are commonly used for in-rack and cross-row data center connections, third-party vendors like Smartoptics offer prices between $1,400 and $1,800 per module.

These modules are cost-efficient, interoperable, and suitable for high-density data center deployments. For longer-reach or coherent modules, such as ZR+ for metro or regional transport, prices can escalate dramatically.

M modules for long-haul DCI applications may exceed $130,000, while third-party alternatives are generally more affordable but still significantly higher than short-reach modules.

Factors Affecting FOB Price

Module Type: SR8 (short-reach), DR4/FR4 (medium reach), ZR/ZR+ (long-haul coherent)Transmission Distance: Longer distances require more advanced optics, increasing costVendor: OEM modules are typically more expensive than third-party vendors like SmartopticsVolume Discounts: Bulk purchases can reduce per-unit cost, though these tiers are often undisclosed Additional Features: AES-256 encryption, OTN compliance, and DWDM support can add to the price Smartoptics QSFP-DD HighlightsSupports 400G and 800G Ethernet speedsCompatible with 400ZR and 800ZR networksOffers short-range multimode, coherent DWDM, and 2x100G optionsProvides cost-efficient Layer 1 security and multi-vendor interoperability SummaryFor budgeting purposes, expect Smartoptics 400G QSFP-DD short-reach modules to cost around $1,400–$1,800 FOB, while coherent or long-haul modules will be significantly higher.

Prices are influenced by module type, reach, vendor, and additional features, and volume discounts may apply for large orders.
