100Ghz 1x48 Athermal Arrayed-waveguide grating DWDM module C13 to
C60 wavelength
GEZHI 1x48 Athermal Arrayed-waveguide grating DWDM is by
silica-on-silicon planar technology. The AWG chips which GEZHI used
for DWDM Mux/Demux are targeted for Long-Haul / Metro and access
applications, where outstanding optical performance and low cost
are paramount.
The arrayed-waveguide grating (AWG) wavelength division
multiplexers and demultiplexers with 100 GHz channel spacing. The
wavelength from C13 to C60 wavelength with LC/UPC connector.
The AAWG circuit chips, which are planar lightwave circuits (PLCs)
are fabricated . These silica-on-silicon waveguide exhibit
exceptional material uniformity, low polarization dependence and
low propagation loss.
