Right now, cross-connects have to convert light impulses into electrons before switching a signal and sending it back out as light.

FORBES: Survival technique: paranoia

That happens because, provided those electrons that have given off light are quickly pumped back to their excited states, the light bouncing around between the mirrors will stimulate the production of yet more light and a powerful, coherent beam will emerge.
