QSFP optical modules, including DML types, are available in Tajikistan with prices ranging from under $2,000 for short-reach 400G modules to over $130,000 for long-haul OEM modules, depending on type and vendor.

Price Ranges by Module Type

• 400G QSFP-DD DML Modules: Short-reach SR8 modules typically cost $1,400–$1,800 from reputable third-party vendors, while long-haul coherent ZR+ modules can exceed $130,000 from OEMs, reflecting differences in transmission distance and technology complexity (Fibermall) .
• 100G QSFP28 Modules: Prices are influenced by engineering, BOM, and production costs, with third-party modules often 50–90% cheaper than OEM equivalents (Vitex, QSFPTEK) .
• 40G QSFP+ Modules: Available for distances from 150m to 400m, with pricing generally lower than 100G and 400G modules; for example, the GBICS QSFP-40G-ESR4 module is available for delivery to Tajikistan via desertcart, with pricing including taxes and shipping (Desertcart) .

Vendors and Availability in Tajikistan

• QSFPTEK: Offers 1G–400G modules with competitive pricing, cutting up to 90% off OEM costs. Modules are factory-tested for quality and compatibility, and they ship internationally, including to Tajikistan (QSFPTEK) .
• Desertcart: Provides Dell EMC-compatible QSFP+ modules, including 40GBASE-ESR4, with delivery to major Tajik cities like Dushanbe, Khujand, and Kulob. Desertcart ensures authenticity and handles customs and shipping (Desertcart) .
• FS and Vitex: Provide detailed pricing guides and cost breakdowns for 40G, 100G, and 400G modules, useful for benchmarking and comparing OEM vs third-party options (FS, Vitex) .

Key Considerations

• Module Type and Reach: Prices vary significantly based on transmission distance (short-reach vs long-haul) and technology (DML vs EML, coherent vs non-coherent).
• OEM vs Third-Party: Third-party modules offer substantial cost savings while maintaining compatibility, but OEM modules may be required for certain vendor-specific equipment.
• Volume Discounts: Many vendors provide tiered pricing for bulk purchases, which can reduce the total cost of ownership.
• Shipping and Taxes: For Tajikistan, platforms like Desertcart include shipping and applicable taxes in the listed price, simplifying procurement. For Tajikistan buyers, short-reach 400G DML modules from third-party vendors are the most cost-effective entry point, while long-haul or OEM modules should be budgeted carefully due to high costs. Checking multiple vendors and considering volume discounts is recommended to optimize procurement.
