Athermal Arrayed Waveguide Grating 48channels 50GHZ

Athermal AWG DWDM (Arrayed Wave-guide Grating Dense Wavelength Division Mux/Demultiplexer) Modules are part of a series of high-performance products based on silica-on-silicon planar technology and a unique athermal packaging design requiring no electrical power, software or temperature control for a completely passive DWDM solution. This product range offers a combination of very low loss and high channel isolation along with long term reliability. Each module can perform Mux and Demux functions. C-Band device is available with Gaussian or Flat top spectral response. Custom frequency grids, fiber types and connector insertion options are also available. We can offer different packages for different products, including a compact box package and 19" 1U rack-mount.
