C-band 40ch 100GHz Athermal AWG DWDM Modules for Metro & long haul
Networks
GEZHI Dense Wavelength Division Multiplexer (DWDM) modules, which
use Athermal Arrayed Waveguide (AWG) technology. The module can
also provide a splitter (i.e. tap), for sampling and monitoring
link traffic.
Athermal AWG (AAWG) DWDM Module have equivalent performance to
standard Thermal AWG(TAWG) but require no electrical power for
stabilization. They can be used as direct replacements for Thin
Film Filters(Filter type DWDM module) for cases where no power is
available, also suitable for outdoor applications over -30 to +70
degree in access networks.
Features
100-GHz channel spacing
Wide-Band design - maximizes uniformity in passband
Athermal design for non-powered distribution nodes.
Standard Fiber Connectors: SC, ST, FC, LC, or customized
Connector Polish: UPC or APC (as applicable)
Pigtail modules also available
Can be used as Mux or Demux
Applications
WDM transmission
WDM based ADM
Metro and long haul net works
Wavelength selective routing
Optical signal processing
