Price list for QSFP-DD active optical modules for data center interconnection

Fiber optic patch cord knowledge brief Published 14 Jul 2024

Prepared for preliminary research by the JEWELBLU OPTICAL knowledge desk. Confirm connector types, fiber grades, polish, loss budgets and installation requirements against current standards and product documentation.

QSFP-DD coherent optical modules for DCI range from under $2,000 for short-reach 400G SR8 modules to over $130,000 for long-haul coherent ZR+ OEM modules, with third-party alternatives offering significant savings.400G QSFP-DD Modules
  • SR8 (Short Reach, in-rack/cross-row): Typically priced between $1,400 and $1,800 from reputable third-party vendors. These are the standard entry point for 400G adoption in data centers and are widely used for short-distance connectivity .
  • DR4/FR4 (Medium Reach, between rows or campus links): Prices are competitive due to a robust third-party ecosystem, generally lower than OEM LR4 modules, reflecting market compression over the past 18 months .
  • LR4 (Long Reach, DCI): OEM modules can exceed $10,000, making them a significant cost factor in DCI deployments. Third-party alternatives can reduce costs substantially .
  • ZR/ZR+ (Coherent, long-haul DCI): OEM ZR+ modules for long-haul applications can cost over $130,000, while third-party options provide dramatic absolute savings. These modules support distances up to 120 km (ZR) and beyond 1000 km (ZR+) over DWDM networks .
800G QSFP-DD Modules
  • 800G ZR/ZR+ coherent optics: Prices are still stabilizing. Buyers can expect to pay roughly 60–70% of OEM list prices for proven third-party 800G transceivers. OEM modules are often preferred for critical production workloads due to DOM integration and firmware compatibility .
  • Applications: 800G ZR modules are ideal for single-span DCI links up to 120 km, while 800G ZR+ modules extend to metro or regional interconnects beyond 1000 km .
Key Considerations
  • OEM vs Third-Party: Third-party modules can offer substantial cost savings, especially for coherent ZR/ZR+ optics, without compromising performance if compatibility is verified .
  • Volume Discounts: Vendors often provide tiered pricing, which can significantly reduce the total cost for large-scale deployments .
  • Total Cost of Ownership (TCO): Beyond module price, consider power consumption, reliability, and maintenance when planning DCI infrastructure .
  • Compatibility: Ensure QSFP-DD modules are compatible with existing switch/router ports and support required DWDM distances .
Summary

For data center interconnects, short-reach 400G SR8 modules are the most cost-effective, while coherent ZR/ZR+ modules represent the largest line-item expense. Third-party alternatives provide meaningful savings, particularly for long-haul DCI deployments. 800G QSFP-DD coherent modules are emerging, with prices still maturing, and OEM modules are often chosen for mission-critical applications .
