Cost LPO optical module QSFP28

The cost of LPO QSFP28 optical modules typically ranges from $200 to $800 per unit, depending on type, distance, and vendor.

Pricing Overview

LPO QSFP28 modules, used for 100G Ethernet connectivity, vary in price based on optical technology, reach, and quality. Short-reach multimode modules (SR4) are generally less expensive, while long-reach single-mode modules (LR4, ER4, ZR4) can cost significantly more due to higher-grade lasers and precision optics ( ).

• Short-reach (100m–150m, SR4): $200–$350 per module
• Medium-reach (2km–10km, LR4): $400–$600 per module
• Long-reach (40km–80km, ER4/ZR4): $600–$800+ per module

Factors Affecting Cost

1. Engineering and Testing: Modules undergo Design Verification Tests (DVT) and Qualification Tests to ensure performance and reliability, which adds to the cost ( ).
2. Bill of Materials (BOM): High-quality chipsets, lasers, optical mux/demux, and mechanical components influence pricing ( ).
3. Production and Assembly: Labor, equipment, and testing resources contribute to the final cost ( ).
4. Vendor and Brand: OEM modules from Cisco, Juniper, or Arista are typically more expensive than third-party or compatible modules ( ).
5. Purchase Volume: Bulk orders often reduce per-unit cost due to economies of scale ( ).

Purchasing Considerations

• Ensure compatibility with your switch or router, as not all QSFP28 modules are interchangeable ( ).
• Verify distance requirements and fiber type (OM3/OM4 for multimode, single-mode for long reach).
• Check for warranty, technical support, and return policies, especially when sourcing from third-party vendors ( ). In summary, LPO QSFP28 modules cost between $200 and $800, with the exact price determined by reach, optical type, vendor, and production quality. Careful selection based on network requirements and vendor reliability ensures optimal performance and cost-effectiveness ( ).
