(A) SEM of the 37c fiber used for high capacity MIMO-based MDM transmission along with a modally resolved loss measurement showing increasing loss with increasing mode order. (B) Experimental set up for MDM transmission with inset showing both the WDM channel allocation and input 16 PDM:QAM constellation diagram. (C) Transmission results showing successful 96 WDM channel, 6-mode (3×MDM×2PDM), 25 GBaud/s 16 QAM transmission over 350 m of HC-PBGF [55].
