Price list for QSFP-DD access switches for data center interconnection

QSFP-DD aggregation switches for DCI range from $1,400 per 400G module for short-reach optics to over $130,000 for long-haul coherent ZR+ modules, with high-density 64-port 400G switches priced in the tens of thousands depending on vendor and configuration.QSFP-DD Module PricingShort-Reach (SR8) Modules: Ideal for in-rack or cross-row connections, priced between $1,400 and $1,800 from reputable third-party vendors, making them the most cost-effective option for 400G adoption .Medium-Reach (DR4/FR4) Modules: Used for inter-row or campus links, prices are competitive due to third-party availability, generally $3,000–$6,000 depending on vendor and volume .Long-Reach (LR4, ZR, ZR+) Modules: Required for DCI over longer distances, OEM LR4 modules can exceed $10,000, while coherent ZR+ modules for ultra-long-haul DCI can reach $130,000, though third-party alternatives can offer significant savings .High-Density Aggregation SwitchesNADDOD N9200-64DC: A 64-port 400G QSFP-DD switch with 25.6 Tbps throughput, suitable for AI, HPC, and large-scale DCI deployments. Supports spine-leaf full-mesh architecture, redundant power/fan modules, and low-latency, high-bandwidth transmission. Pricing is vendor-dependent but typically tens of thousands of dollars per unit .HPE Networking Comware 5965: High-performance 64-port 400G QSFP-DD switch with 25.6 Tbps switching capacity, sub-microsecond latency, and advanced features like VXLAN, EVPN, RoCEv2, and microsegmentation. Pricing is indicative and set by resellers, generally in the high tens of thousands USD range, excluding taxes and shipping .Considerations for ProcurementOEM vs Third-Party Modules: Third-party modules can reduce costs dramatically, especially for long-haul DCI optics, without compromising performance for most deployments .Volume Discounts: Many vendors offer tiered pricing for bulk purchases, which can significantly lower TCO for large-scale deployments .Deployment Scope: Short-reach modules are sufficient for in-rack or cross-row aggregation, while LR4/ZR/ZR+ modules are necessary for inter-data center links.TCO Analysis: Consider not only module and switch costs but also operational efficiency, power consumption, and maintenance when planning DCI infrastructure . For a budget-conscious DCI deployment, a combination of SR8 or DR4 modules with high-density 400G switches provides a balance of performance and cost, while ZR+ coherent optics should be reserved for long-haul interconnects where distance and signal integrity are critical.
