Reduction of Power Consumption of Full C-band WDM Amplification by WDM Sub-banding and SDM Conversion using a High Core Count Multi-Core Amplifier

Abstract

We propose a method for power reduction of amplification by sub-banding wideband WDM signals and using SDM conversion on the sub-bands. We demonstrated 6.6% of power reduction using a 19C-EDFA amplifying 4.8THz of signal bandwidth on the C band.
