QSFP optical module QSFP-DD tariff cost

QSFP-DD module prices range from approximately $1,400 for short-reach third-party modules to over $130,000 for long-haul OEM coherent modules.Price Range OverviewQSFP-DD modules vary widely in cost depending on type, reach, and vendor. Short-reach SR8 modules, commonly used for in-rack or cross-row connections, typically cost $1,400–$1,800 from reputable third-party vendors, making them the most economical entry point for 400G adoption . In contrast, coherent ZR+ modules for long-haul Data Center Interconnects (DCI) can exceed $130,000 from OEMs, reflecting the advanced technology and extended transmission distances .OEM vs Third-Party ModulesOEM modules (e.g., Cisco, Juniper) are generally more expensive due to brand, certification, and support, especially for high-performance coherent optics .Third-party modules (e.g., QSFPTEK) can reduce costs by 50–90% compared to OEMs, while maintaining compatibility and quality through rigorous testing and certification .Volume Discounts and TCOLarge-scale deployments can benefit from volume discount tiers, which are often not publicly disclosed but can significantly reduce per-unit costs . A Total Cost of Ownership (TCO) approach considers not only the module price but also operational efficiency, power consumption, and lifecycle management, which is critical for budgeting in data centers .800G QSFP-DD ModulesFor 800G QSFP-DD coherent optics, prices are higher due to advanced CMOS and coherent technology, supporting up to 120 km for 800ZR and beyond 1000 km for 800G ZR+ . These modules are typically used in metro or regional interconnects and are mechanically compliant with QSFP-DD MSA standards.Key TakeawaysShort-reach 400G SR8 modules: $1,400–$1,800 (third-party)Long-haul 400G ZR+ modules: $130,000+ (OEM)800G QSFP-DD coherent modules: higher, depending on reach and technologyThird-party alternatives can drastically reduce costs while maintaining performanceVolume purchases and TCO analysis are essential for accurate budgeting Understanding the module type, transmission distance, and vendor choice is crucial to estimating the tariff cost accurately for QSFP-DD optical modules.
