Single-fiber wavelength division multiplexer price quote

Single-fiber WDMs typically range from $100 to $500 per unit, depending on wavelength, channel count, and polarization-maintaining features.OverviewA single-fiber Wavelength Division Multiplexer (WDM) is an optical device that combines or separates multiple wavelengths on a single optical fiber, commonly used in fiber-optic communications, fiber lasers, and amplifiers . These devices can be coarse WDM (CWDM) with fewer channels and wider spacing, or dense WDM (DWDM) with many closely spaced channels . Single-mode WDMs are often built using Fused Biconic Taper (FBT) or thin-film filter technology, with options for polarization-maintaining fibers .Price FactorsThe cost of a single-fiber WDM depends on several factors:Wavelength range: Common telecom wavelengths (1310 nm, 1550 nm) are generally less expensive than specialized NIR or visible wavelengths .Channel count: Two-channel WDMs are cheaper than multi-channel CWDM or DWDM devices .Polarization-maintaining (PM) capability: PM WDMs cost more due to precise fiber alignment and micro-optic filter technology .Connector type: FC/PC, FC/APC, LC/UPC, or unterminated leads can slightly affect pricing .Insertion loss and extinction ratio: Higher-performance devices with low insertion loss and high isolation are priced higher .Typical Price RangeStandard 2-channel single-mode WDM: $100–$200 per unit.Polarization-maintaining or specialized wavelength WDM: $250–$500 per unit.Custom multi-channel DWDM modules: Can exceed $500 depending on channel count and spacing .Purchasing OptionsManufacturers like Thorlabs, Agiltron, and CSRAYZER offer WDMs from stock or custom configurations . For exact pricing, it is recommended to request a quote from the supplier, as prices vary with quantity, wavelength specifications, and performance requirements. In summary, a single-fiber WDM generally costs $100–$500, with higher-end or PM devices at the upper end of the range, and custom DWDM modules potentially costing more.
