DWDM Athermal AWG Module
Description
DWDM Athermal Arrayed Waveguide Grating
DWDM AAWG
Dense Wavelength Division Mux/Demultiplexer Athermal Arrayed Waveguide Grating(AAWG) 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. Both C- and L-band devices are available with flat top spectral response. Custom frequency grids, fiber types and connector options are also available.
