AAWG WDM - Athermal Arrayed Waveguide Gratings Wavelength Division Multiplex
There are currently three types of DWDM technologies developed in the industry, which are based on AWG, TFF and FBG technologies. AWG is a planar waveguide device, which is an arrayed waveguide grating made on a chip substrate using PLC technology. Compared with FBG and TTF, AWG has the advantages of high integration, large number of channels, low insertion loss, and easy mass automated production.
The Athermal AWG module is based on the arrayed waveguide grating technology and does not require additional power supply or temperature control. It is a pure passive module. It has the characteristics of low loss and polarization-related loss, low crosstalk, etc., and has good stability in the operating temperature range of -40°C to 85°C.
With the vigorous development of 5G, users will have higher and higher requirements for bandwidth. Operators will need to continuously increase data transmission rates, increase transmission capacity, and reduce operating costs. Among them, the active WDM-PON solution is difficult to deploy on a large scale due to its high cost; while the passive WDM-PON will have more application space due to its advantages of low cost, no power supply, and easy installation. Among them, the non-thermal AWG will be more widely used because of its larger number of channels, denser channel spacing, and no need to rely on power supply or temperature control.
Athermal AWG WDM, also known as Athermal Arrayed Waveguide Grating WDM and AAWG WDM Splitter, along with FBT WDM splitter, LAN WDM splitter, Filter WDM splitter, dense WDM splitter and coarse WDM splitter, are the most commonly used WDM device in construction of PON.
