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.

Solutions of Filter-based WDM Network
The Filter WDM system uses a Multiplexer at the transmitter to
combine several wavelengths together, each one carry different
signal with bite-rate up to 10G and a demultiplexer at the receiver
to split them apart.
