Design and analysis of the high-order mode dispersion compensating fiber

Abstract

We discussed how to design the typical trip-clad high-order mode fiber (HOMF) profiles to achieve the required dispersion properties based on LP02 mode, to compensate all modern transmission fibers, without sacrificing other important properties, such as effective area. Finally, HOMF compensating 100km eLEAF fiber has been designed. Its dispersion at 1550nm is -1217ps/nm/km, and the relative dispersion slope (RDS) is 0.02nm-1. Only ~345m of HOMF is needed to achieve full dispersion and dispersion slope compensation of the span, while maintaining effective area above 52μm2 over the entire C-band.
