The CWDM optical add-and-drop multiplexer launched by Guangzhou Sintai Communications Co., Ltd. is specially 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 1270nm to 1610 nm with optional ITU channel wavelength. It has a series of advantages, such as multi-kind of packaging structures, low insertion loss, high channel isolation and is widely used in CWDM system for wavelength add-and-drop multiplexing.
