Price list for QSFP28SFP optical modules for data center interconnection

QSFP28 modules for 100G data center interconnect typically range from $35 for short-reach third-party modules to $2,200 for OEM long-reach modules, with most third-party LR4 modules around $280 each.

Typical Price Ranges

• Short-Reach (SR4, multimode, up to 100m): Third-party modules can start as low as $35–$50 per module, while OEM versions may cost several hundred dollars depending on brand and warranty .
• Long-Reach (LR4, single-mode, up to 10km): Third-party modules are commonly priced around $280 per module, whereas OEM modules can reach $2,200 per module .
• Extended-Reach (ER4/ZR4, 30–80km): Prices vary widely, typically $1,000–$3,000 depending on vendor, optical performance, and certification .

Factors Affecting Pricing

1. Vendor Type: OEM modules guarantee full compatibility and support with their switches, while third-party modules are often cheaper but may require testing for full interoperability .
2. Module Type and Reach: Longer reach modules (LR4, ER4, ZR4) are more expensive due to higher-quality optics and engineering requirements .
3. Power Consumption: QSFP28 modules typically consume 3.5–4.5W, which can influence operational costs in large deployments .
4. Warranty and Support: OEM modules often include full vendor support and warranty, while third-party modules may offer limited warranty but significant cost savings .
5. Volume Discounts: Bulk purchases can reduce per-unit cost, especially for third-party suppliers .

Example Cost Comparison

• A financial services firm purchased 800 QSFP28 LR4 modules: OEM cost was $2,200 each ($1,760,000 total), while third-party compatible modules were $280 each ($224,000 total), achieving $1.5 million in savings with successful interoperability testing .

Where to Buy

• FS Europe: Offers a variety of 100G QSFP28 modules for data center and HPC networks .
