The CWDM multiplexer/demultiplexer launched by Guangzhou Sintai Communications Co., Ltd. is designed for economical and efficient multi-wavelength CWDM network applications. It is based on thin-film filter (TFF) technology and operates on ITU grids with 20nm channel spacing.
The CWDM wavelength ranges from 1270 to 1610 nm and supports at most 18 channels of optical signal multiplexing/demultiplexing. It has a series of advantages, such as multi-kind of packaging structures, low insertion loss, high channel isolation, and so on.
