Tariff-Cost Tunable Optical Module QSFP28

QSFP28 coherent optical modules typically cost between $280 and several thousand dollars per unit, with coherent ZR modules for long-haul 100G links averaging around $1,500–$3,000 depending on vendor and specifications.

Market Pricing Overview

Standard QSFP28 modules for 100G Ethernet, such as LR4 or CWDM4, can cost $280 per module for third-party options, while OEM modules may reach several thousand dollars each.

Coherent Z

R modules, designed for long-haul 100G transmission over distances up to 80–300 km, are more expensive due to advanced Digital Signal Processors (DSPs), tunable lasers, and silicon photonics front-ends. Typical power consumption ranges from 3. 5W–6W, depending on module type and temperature grade.

Factors Affecting Cost

Engineering and Development: Design Verification Tests (DVT) and Qualification Tests ensure performance and reliability, adding to the module cost. Bill of Materials (BOM): Chipsets, optical mux/demux, mechanical housing, and other components contribute significantly to the final price. Production and Overhead: Labor, equipment, testing, and operational overhead influence pricing.

Vendor Strategy: OEM branding, warranty, support, and volume discounts can create wide price variations.

Coherent Z

R ModulesQSFP28 ZR coherent modules use dual-polarization QPSK modulation and advanced DSPs to extend 100G links over long distances while remaining compatible with standard QSFP28 ports. They are ideal for data center interconnects, metro networks, and 5G transport, and typically cost $1,500–$3,000 per module, depending on vendor and features.

Tariff Considerations

While specific tariffs vary by country, coherent optical modules are generally classified under HS Code 8517. 62 (optical fiber communication apparatus). Import duties can range from 0% to 5–10%, depending on trade agreements and local regulations.

Additional costs may include VAT, customs handling, and shipping, which should be factored into the total landed cost.

Practical Procurement Tips

Consider third-party compatible modules for cost savings if vendor support is not critical. Evaluate power consumption and temperature range for deployment in edge or industrial environments. Include tariffs, VAT, and shipping in budgeting to avoid unexpected costs.

For long-haul coherent deployments, ensure multi-vendor interoperability by selecting modules compliant with OIF 100G ZR MSA standards. By combining baseline module prices with applicable tariffs and logistics costs, organizations can estimate the total cost of acquiring QSFP28 coherent optical modules for their network infrastructure.
