Filter-based wavelength division multiplexing (WDM) filter devices
GEZHI's Filter-based wavelength division multiplexing (WDM) filter devices utilized thin-film filter technology. It multiplexes & demultiplexer three wavelength at 1310, 1490 & 1550nm that carry the voice, data and video services. The Filter-based wavelength division multiplexing (WDM) filter devices combines and separates light to realize bidirectional communication signals at 1310/1490/1550nm wavelength in a wid range. Its used in the "triple-play" FTTH systems with 1 to 2 port configuration. 3wavelengths are fed into the device through the common input port, one wavelength is reflected from one output port, simultaneously, the other 2 wavelengths pass through the device at other output port.
