Price range of 100g optical modules

The price of a 100G QSFP28 optical module ranges from around $35 for short-reach third-party modules to $780 or more for OEM long-reach modules, depending on specifications and vendor.Price RangesShort-Reach (SR4) Modules: Compatible third-party modules can start as low as $35 per module, offering 100G connectivity over multimode fiber for distances up to 100 meters .Long-Reach (LR4) Modules: OEM modules for 10 km single-mode fiber can cost $780 per module, while compatible third-party alternatives may be available for $280 per module .Extended Reach (ER4, ZR4, CWDM4, PSM4): Prices vary significantly based on distance, wavelength, and vendor support, often ranging from $200 to several thousand dollars for OEM versions .Factors Affecting CostEngineering and Development: Design verification, reliability testing, and qualification processes contribute to the final cost .Bill of Materials (BOM): Chipsets, optical components, mechanical housing, and connectors are major contributors .Production and Overhead: Labor, equipment, testing, and general business overhead influence pricing .Vendor Type: OEM modules are typically more expensive due to branding, warranty, and platform coding, while third-party modules can offer significant savings .Purchase Volume and Relationship: Bulk orders and established supplier relationships can reduce per-unit cost .Cost EfficiencyCost per Gigabit: A $35 QSFP28 SR4 module delivers 100G, equating to $0.35 per Gbps, which is more cost-efficient than lower-speed modules like a $20 SFP+ 10G module ($2.00 per Gbps), .Hidden Costs: Shipping, customs duties, spare inventory, and cabling should be considered when budgeting .SummaryFor 2026, third-party 100G QSFP28 modules provide a cost-effective alternative to OEM modules, especially for short- and medium-reach applications. OEM modules remain more expensive due to brand, warranty, and support, but may be preferred for critical deployments requiring guaranteed compatibility. Buyers should evaluate specifications, reach, vendor reliability, and total cost of ownership before purchasing .
