50Ghz 80 Channels Passive Athermal Arrayed Waveguide Grating DWDM Modules
GEZHI's 50Ghz 80 Channels Passive Athermal Arrayed Waveguide Grating DWDM Modules based on silica on silicon technology, is designed for ITU channel spacing applications where no electrical power is required. This Passive Athermal Arrayed Waveguide Grating DWDM Modules operates at 50GHz spacing ITU Grid DWDM wavelengths total 80 channels. The low cost and high performance make it the ideal solution for metro and long-haul DWDM applications. The 50Ghz 80 Channels Passive Athermal Arrayed Waveguide Grating DWDM Modules can be used to replace the traditional TFF (thin film filter) DWDM products for cases where no power is available.
GEZHI 50Ghz 80 Channels Passive Athermal Arrayed Waveguide Grating DWDM Modules is a scalable, high density and standalone passive optical module that perfectly suited to SONET / SDH , transport PDH, ETHERNET services in access and optical metro edge networks.

Compared with the traditional TFF technology, GEZHI AAWG DWDM Module has the following irreplaceable and obvious advantages:
50Ghz 80 Channels Passive Athermal Arrayed Waveguide Grating DWDM Modules has thermal stability and improved ITU-Grid accuracy that ITU-G694.1 requires for with wider transmission bandwidth, thus it can be applied to high-end areas such as long-haul/Metro DWDM optical communication system.
Better PMD feature (< 0.5 ps) enables it to meet the requirements of the 40G/100G DWDM transmission system and the PMD tolerance of the high speed system.
50Ghz 80 Channels Passive Athermal Arrayed Waveguide Grating DWDM Modules does not need external circuit control. As a pure passive product, it can use self-compensation technology to do self-adaptation control for external temperature.
