Abstract
We clear up two issues regarding the eigenvalue problem for the Manakov system; these problems relate directly to the existence of the soliton [\emph{sic}] effect in fiber optic cables.

The first issue is a bound on the eigenvalues of the Manakov system: \emph{if} the parameter $\xi$ is an eigenvalue, \emph{then} it must lie in a certain region in the complex plane.

The second issue has to do with a chirped Manakov system.

We show that if a system is chirped too much, the soliton effect disappears.

While this has been known for some time experimentally, there has not yet been a theoretical result along these lines for the Manakov system.
