Classification of Regenerators
Optical regenerations are classified into 3 categories by the 3 R's scheme.
- R : reamplification of the data pulse alone is carried out.
- 2R : in addition to reamplification, pulse reshaping is carried out. E.g.: Mamyshev 2R regenerator.
- 3R : in addition to reamplification and reshaping, retiming of data pulse is done.
