WDM Configuration Example
The following illustration shows a cartridge style WDM configuration of the
expanded fiber tray.
This application is used to fully segment the GS7000 4-Port Node when limited fiber
counts are available, or as means to conserve fibers for future use.
The GS7000 Node comes with several optical module options to help you combine
3x3, and 4x4 forward and return segments utilizing coarse wave division
multiplexing (CWDM), dense wave division multiplexing (DWDM), and available
analog or digital laser options.
With the use of four 1310 nm/1550 nm WDMs or four 1310 nm CWDMs installed in
the node's expanded fiber tray, the 1310 nm forward path signals can be combined
with the DWDM or CWDM return signals to achieve full 4x4 segmentation with half
the quantity of fibers.
Note: This solution requires WDM modules at headend as shown in the following
