  Multimode fibers (MMFs) offer a cost-effective connection solution for small
and medium length networks. However, data rates through multimode fibers are
traditionally limited by modal dispersion. Signal processing and Multiple-Input
Multiple-Output (MIMO) have been shown to be effective at combating these
limitations, but device design for the specific purpose of MIMO in MMFs is
still an open issue. This paper utilizes a statistical field propagation model
for MMFs to aid the analysis and designs of MMF laser and detector arrays, and
aims to improve data rates of the fiber. Simulations reveal that optimal device
designs could possess 2-3 times the data carrying capacity of suboptimal ones.
