Product Name C-band 80-ch 50GHz Athermal AWG ModuleAthermal
modules are packaged using athermalization techniques with no
electrical power and no temperature control units, can perform
MUX/DeMUX functions. Athermal AWG(AAWG) 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. Lighwit's Athermal AWG(AAWG)
provide excellent optical performance, high reliability, ease of
fiber handling and power saving solution in a compact package.
Different input and output fibers, such as SM fibers, MM fibers and
PM fiber can be selected to meet different applications. We can
just offer 19" 1U rackmount package for 50G AWG products.The planar
DWDM components(Thermal/Athermal AWG) from
Lightwit Photonics are fully qualified according to
Telcordia reliability assurance requirements for fiber optic and
opto-electronic components (GR-1221-CORE/UNC, Generic Reliability
Assurance Requirements for Fiber Optic Branching Components, and
Telcordia TR-NWT-000468, Reliability Assurance Practices for
Opto-electronic Devices).2. Optical Specifications All
specifications guaranteed over the operating temperature range.
