Optical Wavelength Division Multiplexer Price Quote

Optical Wavelength Division Multiplexers (WDMs) typically range from $50 to several hundred dollars, depending on type, wavelength range, and specifications.

Price Overview

Coarse WD

M (CWDM): These devices, used for simpler telecom or fiber-optic applications, generally cost $50–$150 per unit on marketplaces like eBay.

Dense WD

M (DWDM): DWDM devices, which support more channels and tighter wavelength spacing, are more expensive, often $200–$500 or higher, depending on channel count and insertion loss.

Filter-based WD

Ms (FWDM): FWDMs using Thin Film Filter (TFF) technology for applications like EDFA, Raman amplifiers, or FTTx networks typically fall in the $100–$400 range, with higher-end models offering low insertion loss, high isolation, and environmental stability. Laboratory or specialty WDMs: Single-mode, polarization-maintaining, or custom wavelength WDMs from suppliers like Thorlabs or OZ Optics may cost $150–$600, depending on wavelength combination, connector type, and power handling.

Factors Affecting Price

Wavelength Range: Devices covering standard telecom bands (1310 nm, 1550 nm) are generally less expensive than those covering specialized NIR or visible wavelengths. Insertion Loss and Isolation: Lower insertion loss and higher isolation specifications increase cost. Connector Type: FC/PC, FC/APC, or unterminated leads can affect pricing.

Channel Count: DWDM devices with more channels or ultra-dense spacing are more expensive than CWDM with fewer channels. Power Handling: High-power WDMs for fiber lasers or amplifiers are priced higher due to specialized coatings and pigtail processing.

Purchasing Options

Online marketplaces: eBay offers a wide range of WDMs with fast shipping and competitive prices. Specialty suppliers: Thorlabs, Fiber-Mart, and OZ Optics provide WDMs with detailed specifications and the option to request a custom quote for precise pricing. Custom or high-performance WDMs: For applications requiring specific wavelength combinations, low insertion loss, or high-power handling, contacting suppliers directly for a quote is recommended.

In summary, WDM prices vary widely based on type, wavelength, and performance requirements, ranging from around $50 for basic CWDM units to several hundred dollars for DWDM or specialty devices. For exact pricing, especially for high-performance or custom WDMs, requesting a quote from suppliers like OZ Optics or Thorlabs is the most reliable approach.
