QSFP28 optical module high temperature resistant FOB price

High-temperature QSFP28 modules typically support -40°C to 85°C operation, with costs ranging from $400 to $1,200 per module depending on type, distance, and vendor.

High-

Temperature QSFP28 ModulesIndustrial-grade QSFP28 optical transceivers are designed for harsh environments, including outdoor edge computing, telecom, and industrial applications. These modules can operate reliably in temperatures from -40°C to 85°C, compared to standard commercial modules rated for 0°C to 70°C. They often feature enhanced thermal management, robust packaging, and stress-tested components to maintain performance under extreme heat or cold.

Cost Factors

The price of high-temperature QSFP28 modules depends on several factors: Engineering and Testing: Modules undergo Design Verification Tests (DVT) and Qualification Tests, including temperature cycling, moisture resistance, and shock tests, which increase development costs. Bill of Materials (BOM): High-quality chipsets, optical components, and mechanical cases suitable for extreme temperatures add to the cost. Production and Yield: Labor, equipment, and testing for industrial-grade modules are more intensive, affecting unit cost.

Module Type and Reach: SR4, LR4, CWDM4, ZR4, and ESR4 modules vary in optical reach and complexity. Longer-reach or single-mode modules generally cost more. Vendor and Volume: OEM customization, coding, and support services can influence pricing.

Bulk purchases may reduce per-unit cost. Typical Price RangeShort-reach multimode (SR4) modules: $400–$600 per moduleLong-reach single-mode (LR4, CWDM4) modules: $700–$1,200 per moduleSpecialized industrial or ESR4 modules: Can exceed $1,200 depending on distance, thermal tolerance, and vendor customization SummaryFor high-temperature applications, industrial-grade QSFP28 modules are recommended, offering -40°C to 85°C operation. Costs are higher than standard commercial modules due to enhanced engineering, materials, and testing requirements, with prices typically ranging from $400 to $1,200 per module depending on type, reach, and vendor.

When selecting modules, consider thermal tolerance, optical reach, and vendor support to ensure reliable performance in extreme environments.
