Offshore Price Coherent Optical Module QSFP28

QSFP28 optical modules in 2026 range from around $35 for basic third-party short-reach models to several thousand dollars for OEM long-reach or specialized modules.

Price Ranges

• Short-Reach (SR4) Modules: Third-party SR4 modules can cost as low as $35–$50, offering 100G connectivity suitable for data centers and enterprise networks . OEM versions may be higher due to branding and warranty support.
• Long-Reach (LR4, ZR4) Modules: LR4 modules typically cost $200–$500, while ZR4 modules for extended distances can reach $1,000 or more, reflecting the higher cost of long-reach optical components .
• Mid-Market Modules (CWDM4, FR1, LR1): These widely available optics are competitively priced, often $100–$300, with multiple suppliers offering MSA-compliant products .

Factors Affecting Cost

1. Engineering and Testing: Design Verification Tests (DVT) and Qualification Tests ensure performance and reliability, impacting final cost .
2. Bill of Materials (BOM): Chipsets, optical mux/demux, mechanical casing, and other components contribute significantly to module pricing .
3. Production and Labor: Assembly, testing, and quality control processes influence the price, especially for OEM modules .
4. Branding and Support: OEM modules often include extended warranties, platform-specific testing, and technical support, which can justify higher prices .

Power Consumption

QSFP28 modules typically consume 3.5W–4.5W, depending on reach, temperature grade, and optical design .

Procurement Considerations

• Third-Party vs OEM: Third-party modules can offer substantial savings without compromising performance if MSA and IEEE specifications are met .
• Compatibility: Ensure EEPROM coding, DOM/DDM calibration, and platform support are verified to avoid deployment issues .
• Volume Discounts: Larger orders and established supplier relationships can reduce per-unit costs .

Example Suppliers

• FS.com: Offers a wide range of 100G QSFP28 modules with nearby warehouse shipping and 30-day returns .
• Cables on Demand: Factory-direct Amphenol XGIGA modules in SR4 and LR1 variants .
• Finisar/II-VI: OEM modules for multimode and single-mode fiber, including extended temperature options for outside plant applications . In summary, offshore QSFP28 module pricing varies widely based on reach, brand, and supplier, with third-party short-reach modules providing the most cost-effective option, while long-reach and OEM modules command higher prices due to specialized components and support.
