Abstract
Coupling of optically pumped amplifiers between two nodes of an optical communications system. Optical pump power from one direction of the bi-direction communication is diverted to power optically pumped amplifiers in the opposite direction of the bi-directional communication. The optical link in the optical communications system may include both forward and backward Raman amplifiers, as well as forward and backward optically (for example, remote optically) pumped amplifiers for any given optical communication direction. Such coupling has the potential to increase reliability and/or efficiency of the optical communications system.
