DWDM Optical Module Wavelength Adjustment
With the rapid development of network technology, Dense Wavelength Division Multiplexing (DWDM) technology is widely used in fiber optic communication systems, especially for long distance transmission, in order to meet the growing demand of users for high-speed data. This tuning capability allows network operators to select a particular wavelength or channel from the available. Before setting the center wavelength of DWDM optical modules, run the display wavelength-map command to view the mapping between the channel number of DWDM optical modules and center wavelength and then run the wavelength-channel channel-number command to set the channel number for the center. The following topics are covered in this chapter: • Time Division Multiplexing Versus Wave Division Multiplexing • Wavelength Division Multiplexing Versus Dense Wavelength Division Multiplexing • Value of.
