The DWDM add-and-drop multiplexer launched by Guangzhou Sintai Communication Co., Ltd. is specially designed for multi-wavelength DWDM network applications. It works on the ITU grid with 100 GHz channel spacing based on thin film filter (TFF) technology. The wavelength range of DWDM is from 1525nm to 1565 nm, and the wavelength of ITU channel is optional. It has a series of advantages, such as multi-kind of packaging structures, low insertion loss, high channel isolation and so on. And it is widely used in wavelength upstream and downstream multiplexing in DWDM systems.
