L. Raddatz et al., INFLUENCE OF RESTRICTED MODE EXCITATION ON BANDWIDTH OF MULTIMODE FIBER LINKS, IEEE photonics technology letters, 10(4), 1998, pp. 534-536
It is shown that multimode optical fiber links that use laser-based tr
ansmitters may be limited in bandwidth to values less than half those
of the over-filled launch bandwidth. A solution to this problem, based
on an offset launch, is therefore proposed, which increases the bandw
idth to more than the over-filled launch.
