Price-tunable optical module QSFP28

QSFP28 optical transceiver modules typically range from $35 for basic short-reach third-party models to $780 or more for OEM long-reach modules, with most compatible LR4 modules around $280 in 2026.Typical Price RangesShort-Reach (SR4) Modules: Prices can start as low as $35 for common third-party modules, suitable for distances up to 100 meters on multimode fiber .Long-Reach (LR4) Modules: OEM LR4 modules can cost $780 per module, while compatible third-party LR4 modules are often available for $280 each, supporting 10 km single-mode fiber .Extended Reach (ER4/ZR4) Modules: Prices increase with reach, with ER4 and ZR4 modules (up to 80 km) generally costing more due to higher-grade optics and engineering requirements .Factors Affecting PriceVendor Type: OEM modules are typically more expensive due to branding, warranty, and vendor support, while third-party compatible modules offer significant cost savings .Engineering and Testing: Costs include design verification, reliability testing, and qualification processes, which are reflected in the final price .Bill of Materials (BOM): Chipsets, optical components, and mechanical housing contribute to module cost .Production and Overhead: Labor, equipment, and operational expenses, along with profit margins, influence pricing .Purchase Volume and Business Strategy: Bulk orders or strategic pricing promotions can reduce per-unit cost .Practical ConsiderationsPower Consumption: QSFP28 modules typically consume 3.5W–4.5W, depending on reach and design .Compatibility: Ensure modules match your switch platform and optical specifications; third-party modules may require verification for full interoperability .Total Cost of Ownership: Consider shipping, customs, spares, and cabling when budgeting for deployment . In summary, QSFP28 module prices vary widely based on reach, vendor, and specifications, with third-party modules offering substantial savings over OEM options while maintaining similar performance for most applications .
