Cost-effective optical router QSFP28

QSFP28 optical transceivers typically range from $200 to $600 per module, depending on type, distance, and vendor.Typical PricingThe Huawei QSFP28-100G-SR4, a common short-range 100G optical transceiver, is priced in the $200–$400 range for single units, though exact pricing depends on vendor, quantity, and support options . Other QSFP28 modules, such as LR4 (long-range) or ER4 (extended-range), generally cost more, often $400–$600 per module, due to higher-quality lasers and longer transmission distances . Vendors like FS and Vitex provide similar modules with comparable pricing, and bulk purchases or enterprise contracts may reduce per-unit cost .Factors Affecting CostModule Type and Distance: SR4 modules are for short distances (up to 100m on multimode fiber), LR4 supports up to 10km on single-mode fiber, and ER4 can reach 40km or more. Longer distances require more advanced optics, increasing cost .Optical Technology: Modules may use VCSELs for multimode or DFB lasers for single-mode applications. PAM4 or CWDM4 variants for higher performance also raise prices .Vendor and Brand: Original equipment manufacturer (OEM) modules like Huawei or Cisco are typically more expensive than third-party or compatible modules .Engineering and Testing Costs: Development, design verification, and reliability testing (temperature cycling, moisture resistance, shock tests) contribute to the final price .Accessories and Support: MPO fiber cables, patch panels, cleaning kits, and protective cases may add to the total cost if purchased together .Market ConsiderationsQSFP28 modules are widely used in data centers, enterprise networks, and high-performance computing environments. Prices fluctuate based on supply chain conditions, global demand for 100G networking, and technological upgrades. For the most accurate pricing, contacting vendors directly or checking online distributors is recommended . In summary, a single QSFP28 module generally costs between $200 and $600, with the exact price influenced by range, optical type, vendor, and additional accessories.
