6 port CWDM device provided is mainly used for passive wavelength division multiplexing modules for dual-fiber transmission. It is a TFF (thin film filter)-based wavelength division multiplexing technology with a variety of package sizes and wavelengths to choose from.
One 6 The CWDM of the port is equivalent to two 3-port products, and the price is equivalent to a 3-port product, in the wavelength division multiplexing system, it can multiplex, demultiplex or add/drop different optical signals, and increase the signal transmission speed.
