Practical applications of all-optical regeneration require from it a graceful scalability with the number of wavelengthdivision-multiplexed (WDM) channels. We describe several main approaches to WDM-compatible regeneration and review in greater detail two recent demonstrations of 16-channel regeneration: one using time-lensing and the other using group-delaymanagement. We discuss scalability, practical issues, and outlook for these WDM regeneration methods.
