| Abstract | |
In this paper, we compare the modal dispersion (MD) in standard and bend-insensitive graded-index multimode fibers (GI-MMFs and BI-MMFs). By selectively exciting 45 modes across 9 mode groups, we observed a maximum differential group delay (between mode group 9 and mode group 1) of 1.14 ns/km in BI-MMF and 2.02 ns/km in standard MMF. The reduced modal dispersion in BI-MMFs is attributed to their trench-structured index profile. Additionally, we discuss the effects of mode coupling on signal integrity and the complexities it introduces for equalization in multimode optical systems. (AU) | |
