Price list for low-noise QSFP optical modules for data center interconnection
QSFP optical module prices vary widely by speed, reach, and vendor, ranging from under $2,000 for short-reach 400G modules to over $130,000 for long-haul coherent ZR+ modules, with third-party options offering significant cost savings.
400G QSFP-DD Modules
- Short-reach SR8 (in-rack connections): Under $2,000 from reputable third-party vendors, ideal for low-latency, low-noise intra-rack links (OEM prices may be higher) .
- DR4/FR4 (row-to-row or campus links): Mid-range pricing; third-party modules are highly competitive, often 50% cheaper than OEM equivalents .
- LR4 (longer DCI links): OEM modules can exceed $10,000; third-party alternatives can reduce costs significantly while maintaining low-noise performance .
- ZR/ZR+ (coherent long-haul DCI): OEM modules may exceed $130,000; third-party options can offer substantial absolute savings, though careful attention to firmware and DOM compatibility is required .
800G QSFP-DD Modules
- Emerging market: Prices are still stabilizing; third-party modules typically cost 60–70% of OEM list prices .
- Use case: High-performance AI clusters or ultra-high-speed DCI where low-latency and low-noise operation are critical .
100G QSFP28 Modules
- Cost factors: BOM, chipsets, production, overhead, and profit margin influence pricing; typical 100G QSFP28 modules range from $500 to $2,500 depending on reach and vendor .
- Low-noise options: Modules designed for minimal signal degradation and high reliability are available from both OEM and third-party suppliers .
40G QSFP+ Modules
- Short to medium reach (150m–80km): Prices are generally lower, ranging from $100 to $1,000 depending on distance and vendor .
- Applications: High-density switching, routing, and intra-data center connections .
Third-Party vs OEM Considerations
- Third-party modules: Can reduce costs by 50–90% compared to OEMs, with rigorous testing for compatibility, eye pattern, BER, and temperature performance .
- OEM modules: Preferred for highly critical production workloads due to guaranteed firmware and DOM integration .
Additional Notes
- Direct Attach Copper (DAC) cables: Cost-effective for in-rack connections under 3 meters .
- Active Optical Cables (AOCs): Premium option for extended intra-row reaches .
- Volume discounts: Many vendors offer tiered pricing for bulk purchases, which can significantly reduce TCO . For a detailed price list and vendor comparison, you can explore suppliers like QSFPTEK, FS, Unitekfiber, and Vitex, which provide transparent pricing and low-noise module options suitable for data center interconnection .
