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

100G QSFP-DD optical modules typically range from $300 to $1,200 per unit depending on type, reach, and vendor, with third-party modules offering significant cost savings over OEM brands.

Pricing Overview

• Short-Reach (SR) Modules: Designed for multi-mode fiber within data centers, prices generally range from $300 to $600 per module. These are suitable for intra-rack or inter-rack connections up to 100 meters. Vendors like QSFPTEK offer compatible SR modules at up to 90% lower cost than OEM brands while maintaining quality certifications such as CE, FCC, RoHS, and ISO9001 .
• Long-Reach (LR) Modules: Single-mode fiber modules for distances up to 10 km typically cost $700 to $1,200 per module. These are used for inter-data center links or metro DCI applications. FiberMall provides QSFP-DD DCO coherent modules for extended C-band and DP-QPSK modulation, suitable for metro and cloud interconnects .
• Coherent Modules: For high-performance DCI or metro networks, coherent 100G QSFP-DD modules can exceed $1,000 per unit, depending on reach and DSP technology. These modules support advanced features like polarization diversity and electronic link equalization .
• Third-Party vs OEM: Third-party vendors such as QSFPTEK and UnitekFiber offer cost-effective alternatives to OEM modules, often cutting 50–90% of the cost while ensuring full compatibility with major switch brands and rigorous testing for BER, eye pattern, and temperature performance .

• MefiberModule: Supplies QSFP-DD modules for scalable data rates up to 400G/800G, supporting both multi-mode and single-mode fiber .

Key Considerations

1. Compatibility: Ensure modules are tested with your switch or router brand to avoid interoperability issues.
2. Reach Requirements: Choose SR for intra-data center links and LR or coherent modules for inter-data center or metro connections.
3. Budget vs Performance: Third-party modules offer significant cost savings, but coherent modules may be necessary for long-distance or high-performance DCI.
4. Certifications: Look for CE, FCC, RoHS, ISO9001, and other quality certifications to ensure reliability in critical data center environments. In summary, 100G QSFP-DD modules for data center interconnection are available across a wide price range depending on reach, technology, and vendor. For short-reach intra-data center links, expect $300–$600 per module, while long-reach or coherent modules can cost $700–$1,200 or more, with third-party vendors providing cost-effective alternatives without compromising quality.
