Abstract

Transmissions over multimode fibers can be done using different techniques, nevertheless, inter-model crosstalk is a main limiting factor for high data rate transmissions. We characterize the statistics of the inter-modal crosstalk in direct detection M-PAM and DMT systems and assess their relative advantages and disadvantages.
