Fiber Optic Module Types and Prices

Fiber optic module prices vary widely, typically ranging from $10 for standard 10G SFP modules to over $10,000 for high-end 400G QSFP-DD modules, depending on type, distance, and brand.10G SFP ModulesThe cost of a 10G SFP+ module generally falls between $10 and $300, depending on the module type, transmission distance, and brand . Short-range SR modules, commonly used in data centers for distances up to a few hundred meters, are at the lower end of this range. Long-range LR modules, which use single-mode optics for longer distances, are more expensive due to tighter manufacturing tolerances and higher optical power requirements. Branded modules from major vendors can cost multiple times more than compatible third-party options, largely due to support contracts and vendor lock-in strategies .400G QSFP-DD ModulesFor 400G QSFP-DD modules, prices are significantly higher. Entry-level SR8 modules for in-rack or short campus links typically cost $1,400 to $1,800, while long-haul coherent ZR+ modules can exceed $130,000 . The cost depends heavily on transmission distance, optical technology, and whether the module is OEM or third-party. Competitive third-party markets have compressed prices for mid-range modules, but high-performance long-distance modules remain expensive .Factors Affecting Module CostTransmission Distance: Longer distances require single-mode optics and higher precision, increasing cost .Module Type: SFP, SFP+, QSFP, QSFP-DD, and other form factors differ in price due to bandwidth and port density.Brand and Vendor: OEM modules are often priced higher than compatible third-party modules.Optical Technology: Coherent optics, DWDM, and advanced modulation increase module cost.Quantity and Bulk Purchasing: Buying in bulk can reduce per-unit cost.SummaryStandard 10G SFP: $10–$300400G QSFP-DD SR8: $1,400–$1,800High-end long-haul 400G modules: $10,000–$130,000+ Understanding your network requirements, including distance, speed, and vendor compatibility, is essential to selecting the right module while managing costs effectively .
