Where to Buy Wavelength Division Multiplexing Devices

CSRAYZER’s single-mode / polarization-maintaining WDM couplers, in filter type or fused type, have low insertion loss, high isolation and excellent environmental stability. Unique pig-tail processing and high quality AR coating ensure high optical power. These components are widely used in EDFAs, fiber lasers, fiber sensors, etc.

O/E Land's WDM multiplexer features low additional loss, high extinction ratio and isolation, high load-carrying power, high stability and reliability. With our unique apodization mask technology and our world class FBG writing technology, DWDM fiber grating filters have been made with more than 40 dB isolation and with a reflection bandwidth at -25 dB of less than 1 nm (100 GHz), 0.5 nm (50 GHz), 0.25 nm (25 GHz), 0.13 nm (12.5 GHz) and 0.06 nm (6.25 GHz). Our high quality DWDM fiber grating filter is the best in the industry, ideal for any kind of DWDM system.

AMS Techno­logies carries a wide range of single mode (SM), multi mode (MM) and polarization maintaining (PM) WDMs in component or module form factors:

• component-style SM WDMs, including “source to fiber”, miniature-size, low-loss fused fiber or SM WDMs widely used in EDFAs
• multi mode (MM) WDMs for 850/1310 nm or covering a wavelength range from 400 to 1600 nm, including visible wavelength (RGB) versions
• fused polarization maintaining (PM) WDMs, available in pigtail, miniature and free-space to fiber styles and including devices with built-in filters

DK Photonics offers filter WDM couplers based on advanced micro-optic filter technology. All input and output fibers are polarization-maintaining. They feature wide-band operation, low insertion loss, high polarization extinction, high return loss and a compact package. They are ideal for PM fiber amplifiers, fiber lasers and instrumentation applications.

Technica provides several of the key components used in wavelength division multiplexing solutions including fiber Bragg gratings (Txxx family of products), Fabry–Pérot etalons and tunable filters (TFPxxx family of products), and athermal references including HCN and C₂H₂ gas cells (TWRxxx family of products).
