Pump energy source, method of providing pump energy to an optical transmission system, and optical transmission system

摘要

It is disclosed a pump energy source ( 20 ) for providing pump energy (E_p) to an optical transmission system ( 100 ) transmitting an optical signal along an optical fiber, in particular an optical transmission system ( 100 ) in which a beam of said pump energy (E_p) is introduced to said optical fiber so that said beam of said pump energy (E_p) copropagates with said optical signal.
