Cost of SD-WAN Equipment QSFP-DD

QSFP-DD transceivers for SD-WAN deployments range from $1,400 for short-reach 400G modules to over $130,000 for long-haul coherent ZR+ modules, with 800G modules generally priced at 60–70% of OEM list prices. QSFP-DD Module Pricing400G QSFP-DD Modules: Short-reach SR8 modules (in-rack or cross-row connections) cost $1,400–$1,800 from reputable third-party vendors, making them the most common entry point for high-speed SD-WAN deployments. DR4 and FR4 modules (for inter-row or campus links) are moderately priced, bridging short and medium distances.

LR4 modules (longer distances) can exceed $10,000 from OEMs, while ZR and ZR+ coherent modules for long-haul connections can reach $130,000, representing the largest line-item expense in wide-area SD-WAN networks. 800G QSFP-DD Modules: Pricing is less commoditized and still stabilizing. Buyers can expect 60–70% of OEM list prices for proven third-party 800G transceivers.

Early adoption often favors OEM modules for critical workloads due to firmware and DOM compatibility considerations. Cabling Costs: Direct Attach Copper (DAC) cables are cost-effective for short in-rack connections, typically around $120 for a 3-meter cable, offering significant savings compared to multiple SR8 modules. Active Optical Cables (AOCs) are required for longer intra-row or inter-rack distances and command a premium.

SD-WAN Deployment ConsiderationsSD-WAN appliances using QSFP-DD modules benefit from high-bandwidth connectivity, supporting multiple transport types (fiber, LTE/5G, fixed wireless) and centralized management. Monthly recurring costs (MRC) for SD-WAN vary by bandwidth and vendor. For example, 2Gbps connections can range from $496 to $1,256 per month per site, reflecting differences in vendor pricing, throughput, and service features.

Total cost of ownership includes transceivers, cabling, SD-WAN appliances, and ongoing subscription fees, so module selection directly impacts both capital and operational expenses.
