The DWDM multiplexer/demultiplexer launched by Guangzhou Sintai Communication Co., Ltd. is designed for multi-wavelength DWDM network applications. It works on an 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 with an optional ITU channel wavelength. It has a series of advantages, such as multi-kind of packaging structures, low insertion loss, high channel isolation, and so on.
