Price of Fixed Optical Attenuator

Fixed optical attenuators typically range from $10 to $150 per unit, depending on type, connector, and attenuation value.OverviewFixed optical attenuators are devices designed to provide a constant optical loss in fiber-optic systems, commonly used for receiver protection, power balancing, and testing in single-mode (SM), multimode (MM), or polarization-maintaining (PM) fibers . They are available with various connector types such as FC, SC, LC, SMA, and can be designed for specific wavelength ranges (e.g., 1240–1620 nm for single-mode fibers), .Price FactorsFiber Type: Single-mode and polarization-maintaining attenuators are generally more expensive than multimode versions due to higher precision requirements .Connector Type: APC connectors often cost more than PC/UPC connectors because of their angled design, which reduces back-reflection .Attenuation Value: Higher dB values (e.g., 20 dB or more) may slightly increase cost, though most standard values like 5 dB, 10 dB, and 15 dB are widely available at lower prices .Brand and Quality: Reputable suppliers such as Thorlabs, FS, and DigiKey offer attenuators with guaranteed tolerances and wavelength specifications, which can affect pricing .Typical Price RangeLow-end / basic multimode attenuators: $10–$30 per unitStandard single-mode fixed attenuators (5–15 dB): $30–$80 per unitHigh-precision or polarization-maintaining attenuators: $80–$150 per unit Bulk kits or sets, such as Thorlabs' attenuator kits containing multiple fixed attenuators and terminators, may cost $100–$200 depending on the number of components and connector types included .SummaryThe price of fixed optical attenuators varies primarily with fiber type, connector type, and attenuation precision. For most standard applications, expect to pay $10–$80 per unit, while specialized or high-precision attenuators can reach $150 or more. Choosing the right attenuator involves balancing cost with required performance, wavelength range, and connector compatibility .
