Abstract :
We investigate link restoration in optical networks carrying multiple data-rates. We compare rate-tunable opto-electronic interfaces (elastic) versus rate-specific (fixed) technologies and show the reconfiguration ability of elastic interfaces strongly reduces the required spare resources.
