Price list for SFP LPO optical modules for data center interconnection

SFP coherent optical modules for DCI range from under $2,000 for short-reach 400G modules to over $130,000 for OEM 400G/800G ZR+ long-haul modules, with third-party options offering significant savings.Pricing OverviewShort-Reach 400G Modules (SR8): Typically used 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 entry point for 400G adoption .Medium-Reach Modules (DR4, FR4): Bridge data center rows or campus links. Third-party competition has driven prices down, though exact figures vary by vendor .Long-Reach Modules (LR4, ZR, ZR+): Used for DCI over longer distances. OEM LR4 modules can exceed $10,000, while coherent ZR+ modules for extended metro or regional interconnects may surpass $130,000 . Third-party alternatives can reduce costs by 30–40% or more.800G QSFP-DD Modules: Pricing is still stabilizing. Buyers can expect 60–70% of OEM list prices for proven third-party 800G transceivers, with OEM modules preferred for critical workloads due to firmware and DOM compatibility .Vendor ExamplesCisco 800G QSFP-DD and OSFP ZR/ZR+ Modules: Support 800G traffic over DWDM links up to 120 km for 800ZR and over 1000 km for 800G ZR+, suitable for single-span DCI or metro/regional interconnects .GIGALIGHT Coherent Modules: Offer 100G, 200G, and 400G pluggable digital coherent optical transceivers compatible with DCI BOX transport platforms, providing cost-effective solutions for long-haul and metro DCI applications .ConsiderationsOEM vs Third-Party: OEM modules are more expensive but may offer better compatibility and support. Third-party modules can provide substantial savings, especially for large-scale deployments .Module Type Selection: The choice between SR, DR, LR, ZR, and ZR+ depends on distance, network topology, and required bandwidth. Coherent modules are essential for long-haul DCI links.Total Cost of Ownership (TCO): Beyond module price, consider cabling (DAC vs AOC), optical amplifiers, and network infrastructure when budgeting for DCI deployments . In summary, SFP coherent optical module prices vary widely based on reach, speed, and vendor. Short-reach 400G modules are relatively affordable, while long-haul 400G/800G ZR+ modules represent the largest line-item expense in DCI networks. Third-party modules offer significant cost savings without compromising performance for many applications.
