Price list for QSFP fiber optic enterprise routers for data center interconnection

QSFP-DD module prices range from approximately $1,400 for short-reach 400G SR8 modules to over $130,000 for long-haul coherent ZR+ modules.Price Ranges by Module Type400G SR8 (Short-Reach, in-rack/cross-row): $1,400–$1,800 from reputable third-party vendors, ideal for standard data center deployments .400G DR4 and FR4 (Medium-Reach, row-to-row or campus links): Prices vary depending on vendor and distance, typically higher than SR8 but significantly lower than long-haul coherent modules .400G/800G ZR and ZR+ (Long-Haul Coherent, DCI applications): OEM modules can exceed $130,000, supporting distances from 120 km (800ZR) up to 1,000 km (800G ZR+) over DWDM networks .OEM vs Third-Party ConsiderationsOEM modules (e.g., Cisco, Juniper, Arista) generally command higher prices due to brand, warranty, and guaranteed interoperability .Third-party modules offer cost savings, especially for short-reach deployments, but require careful verification of compatibility with your router or switch .Factors Affecting PricingTransmission Distance: Longer distances and coherent optics significantly increase cost.Connector Type: Duplex LC vs MPO-12 or other parallel interfaces can influence pricing.Module Speed: 400G modules are generally less expensive than 800G modules due to lower complexity.Volume Discounts: Bulk purchases can reduce per-unit cost, though these tiers are often undisclosed .Example Cisco QSFP-DD Modules400GBASE-DR4, MPO-12, 500m: Entry-level short-reach module.400G-FR4, Duplex LC, 2 km: Medium-reach module for intra-data center links.400GBASE-LR8, Duplex LC, 10 km: Long-reach module suitable for campus or metro DCI.400G-ZR/ZR+ Coherent DCO: High-performance long-haul modules for metro/regional interconnects .Deployment InsightsQSFP-DD modules are primarily used in high-performance data center fabrics, hyperscale cloud environments, and AI clusters where East-West traffic is heavy. Short-reach SR8 modules dominate in-rack and cross-row connections, while ZR/ZR+ coherent modules are reserved for long-haul DCI applications . Selecting the right module involves balancing cost, reach, and compatibility with your existing infrastructure. For large-scale deployments, considering TCO (Total Cost of Ownership), including power consumption and lifecycle, is recommended .
