Product Description

Product Name C-band 80-ch 50GHz Athermal AWG Module
Athermal 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).
