Study and application with EoS technical for the optical supervisory channel on WDM networks

After the management channel technique and methods were analysed comparatively between network elements on WDM optical networks, some suggests were pointed out in the process of design. An Optical Supervisory Channel System realized with ethernet over SDH was brought to success and tested. The advantages of the system were discussed. it shows very important significance for interlinkage in WDM optical networks.
