IET Optoelectronics, Volume 18, Issue 6, Page 179-187, December 2024.Multicore (MC‐) erbium‐doped fibre amplifier (EDFA) architecture is classified from the viewpoint of the number of erbium‐doped fibre (EDF) cores and its pumping method. In particular, the advantages of cladding pumped MC‐EDFA are shown. Abstract Amplification technologies needed for spatial division multiplexing (SDM) signal transmission have been ...
