The athermal Array Waveguide Grating Module (AWG) from Sintai is based on waveguide grating technology on the silicon substrates and adopts the unique thermal-free package design, which is a completely passive DWDM solution without power, software, or temperature control. 

Accurate channel coupling, low insertion loss, high channel isolation, and high stability can be achieved. Each module has multiplexing and de-multiplexing functions and is one of the most important devices in the DWDM system.
