Price List for 400g Optical Modules

The price of 400G optical modules ranges from around $1,400 for short-reach SR8 modules to over $130,000 for long-haul ZR+ modules, depending on type, reach, and vendor.Price Ranges by Module TypeSR8 (Short-Reach, In-Rack): Typically priced between $1,400 and $1,800 from reputable third-party vendors, making them the most cost-effective option for standard data center deployments .DR4/FR4 (Medium-Reach, Cross-Row or Campus Links): Prices are higher than SR8 modules, reflecting longer reach and more complex optical design .ZR+ (Long-Haul, Data Center Interconnect): Can exceed $130,000 from OEMs due to advanced coherent optics and extended transmission distances .Factors Affecting PriceForm Factor and Compatibility: QSFP-DD, OSFP, and CFP2 form factors have different tooling and thermal requirements. Larger or niche form factors often carry a 5–15% premium due to lower production volumes and higher non-recurring engineering costs .Optical Reach and Modulation: Modules using PAM4 signaling or coherent optics for long distances are more expensive than short-reach NRZ-based modules .Vendor Type: OEM modules are generally more expensive than third-party alternatives, sometimes by a factor of 10 or more, depending on the module type and support services .Volume and Procurement Strategy: Bulk purchases or long-term contracts can reduce per-unit costs, while small orders may face higher pricing due to limited economies of scale .SummaryFor most data center applications, 400G SR8 modules provide a cost-effective entry point at around $1,400–$1,800, while medium- and long-reach modules like DR4, FR4, and ZR+ can range from several thousand to over $130,000 per unit. The final price depends on module type, optical reach, form factor, and vendor selection, so careful planning and specification matching are essential to optimize total cost of ownership .
