Abstract
A wavelength selective switch includes a first optical pathway for carrying first and second wavelengths to and from a first direction, a second optical pathway for carrying at least one wavelength to and from a second direction, a first add/drop port in communication with at least one of the first and second optical pathways over a third optical pathway, a first tunable wavelength topology coupled with the third optical pathway and one of the first and second optical pathways for optical transport of the first wavelength from the first direction to the first add/drop port, a second tunable wavelength topology coupled with the third optical pathway and one of the first and second optical pathways for optical transport of the second wavelength from the first add/drop port to the first direction. The first and second tunable wavelength topologies are configured to dynamically re-tune to a third wavelength.
