Price List for QSFP-DDSD-WAN Equipment for Data Center Interconnection

QSFP-DD transceiver prices vary widely, from around $1,400 for short-reach 400G modules to over $130,000 for long-haul coherent ZR+ modules, depending on type, reach, and vendor.Price Ranges by Module TypeShort-Reach (SR8) 400G Modules: Ideal for in-rack or cross-row connections, priced between $1,400 and $1,800 from reputable third-party vendors .Medium-Reach (DR4/FR4) Modules: Used for inter-row or campus links, prices are competitive due to third-party market pressure, generally $2,000–$5,000 depending on vendor and volume .Long-Reach (LR4) Modules: Suitable for DCI over tens of kilometers, OEM prices can exceed $10,000, while third-party alternatives may offer significant savings .Coherent ZR/ZR+ Modules: Designed for metro or regional DCI, 400G–800G coherent optics can range from $30,000 to $130,000+, depending on reach (up to 120 km for 800ZR, over 1000 km for 800G ZR+) and vendor .Vendor OptionsCisco: Offers QSFP-DD and OSFP 800G ZR/ZR+ coherent optics, compliant with QSFP-DD MSA, suitable for single-span DCI or extended DWDM networks .Third-Party Vendors (e.g., QSFPTEK, FS): Provide compatible 400G–800G modules at 50–90% lower cost than OEMs, with quality assurance and testing for interoperability .Additional ConsiderationsTransmission Distance: Longer distances and coherent optics significantly increase cost.Volume Discounts: Bulk purchases from third-party vendors can reduce per-unit cost.Total Cost of Ownership (TCO): Consider module lifespan, power consumption, and maintenance when budgeting for DCI deployments . For procurement, short-reach SR8 modules are the most cost-effective for in-data-center links, while coherent ZR/ZR+ modules dominate the budget for long-haul DCI. Third-party vendors offer substantial savings without compromising compatibility, making them a viable alternative to OEM pricing.
