Price list for 100G QSFP optical modules for data center interconnection

100G QSFP28 modules range from approximately $35 for short-range third-party modules to over $2,200 for OEM long-range modules, depending on type, vendor, and reach.

Overview of 100G QSFP28 Module Pricing

• Short-Range (SR4, up to 100m on multimode fiber): Third-party modules can cost as low as $35 per module, offering a very low cost per Gbps (~$0.35/Gbps) while OEM versions may be higher depending on vendor branding and support .
• Long-Range (LR4, up to 10km on single-mode fiber): OEM modules can reach $2,200 per module, whereas compatible third-party LR4 modules are available for around $280 per module, providing significant cost savings for large-scale deployments .
• Extended Reach (ER4, ZR4, up to 80km): Prices vary widely depending on vendor and optical reach, typically higher than LR4 due to advanced optics and longer distance support .

Factors Affecting Pricing

1. Vendor Type: OEM modules include vendor-specific coding, firmware, and support, which increases cost. Third-party modules are often MSA-compliant and compatible with multiple switch platforms, offering lower prices but may require testing for full interoperability .
2. Optical Reach: Modules supporting longer distances (LR4, ER4, ZR4) are more expensive due to higher-quality components and stricter performance requirements .
3. Volume Discounts: Bulk purchases can significantly reduce per-unit cost, especially for third-party modules .
4. Platform Compatibility: Some switch vendors enforce strict vendor checks; modules with platform-specific coding may be required for locked systems, affecting pricing .

Example Pricing from Suppliers

• QSFPTEK: Offers 100GBASE-SR4/LR4/ER4/ZR4 modules ranging from 100m to 80km, with pricing dependent on reach and type .
• Cables on Demand (Amphenol XGIGA): QSFP28-SR4 modules for short-range multimode fiber (~100m) and QSFP28-LR modules for single-mode fiber up to 10km, factory-direct pricing available upon request .
• Huawei QSFP28-100G-SR4: OEM short-range module for high-performance data centers; pricing requires direct inquiry with the vendor .

Cost-Saving Considerations

• Using MSA-compliant third-party modules can reduce costs by up to 90% compared to OEM modules for LR4 deployments, while maintaining similar performance and reliability .
• Testing modules on actual switch platforms before large-scale deployment ensures compatibility and avoids operational issues. In summary, 100G QSFP28 module prices vary widely based on range, vendor, and support. Short-range third-party modules are highly cost-effective, while long-range OEM modules are significantly more expensive. Careful selection and testing of third-party modules can provide substantial savings for data center interconnections.
