摘要:This invention relates to provisioning wavelength-selective switches and
reconfigurable optical add-drop multiplexers to minimize the bandwidth narrowing effect
from the optical filters. Novel architectures and methods are disclosed that can
significantly reduce bandwidth-narrowing on channels in a reconfigurable WDM network
where a large number of optical filter elements are cascaded. Instead of blocking unused
channels as in the prior art, unused channels are selectively provisioned depending on the
state of their adjacent channels. Unused adjacent channels of an active channel are
provisioned to follow the same path as the active channels. As each channels is deployed,
the channel frequency is selected so as to minimize bandwidth narrowing.
