Optical Communications Repeater - Classification of Regenerators

Classification of Regenerators

Optical regenerations are classified into 3 categories by the 3 R's scheme.

  1. R : reamplification of the data pulse alone is carried out.
  2. 2R : in addition to reamplification, pulse reshaping is carried out. E.g.: Mamyshev 2R regenerator.
  3. 3R : in addition to reamplification and reshaping, retiming of data pulse is done.
