Optical network element and optical transmission system

摘要

The invention relates to an optical network element (100; 200), particularly optical line terminal, OLT, for transmitting (540) and receiving (560) signals via at least one optical fiber link (500), wherein said optical network element (100; 200) comprises primary optical pumping means (166; 266) and secondary optical pumping means (146; 246) for providing optical pump power to said at least one optical fiber link (500), wherein said primary optical pumping means (146; 246) and/or said secondary optical pumping means (166; 266) are preferably integrated into said optical network element (100; 200).
