Multiplexer specifications
This section describes multiplexer specifications. Use the specifications
to help ensure proper network operation. Multiplexer loss values include
connector loss.
There is one nanometer (nm) offset between the stated wavelength for
the Coarse Wavelength Division Multiplexing (CWDM) Gigabit Interface
Converters (GBIC) and the CWDM optical add/drop multiplexers (OADM)
due to a shift in the center wavelength of the CWDM GBIC as it reaches
typical system operating temperature.
