Abstract
We identify an optimal ovality range for elliptical multimode fiber that support 45 spatial modes. These fibers significantly reduce intramode crosstalk by 11 dB over 10 km fiber length, while minimizing the group delay spread. A 32 GBd 16-QAM dual polarization transmission over a 10 km fiber with crosstalk strength as -20 dB/km demonstrates that the DSP equalization requirements at the receiver are halved with optimized elliptical core fibers compared to circular core fibers. These findings suggest that elliptical core fibers are a promising solution for enabling low-complexity multimode fiber systems.
