A method includes receiving a restoration indicator associated with a path
that includes an optical cross-connect (OXC). The OXC is reconfigured
from a standby configuration to a restoration configuration in response
to the restoration indicator. An optical signal received in a first
direction at a first wavelength is optically regenerated to produce an
optical signal in the first direction at a second wavelength. An optical
signal received in a second direction at the second wavelength is
optically regenerated to produce an optical signal in the second
direction at the first wavelength.
