Abstract
An optical network includes a first optical network for carrying a plurality of optical channels in an optical fiber, wherein each of the plurality of optical channels comprise a discrete wavelength in a first range of wavelengths. A second optical network coupled to the first optical network by a first tunable filter. A first customer location coupled to the second optical network by a second tunable filter. The first tunable filter is configured to pass a first set of optical channels from the first optical network to the second optical network. The first set of optical channels includes a subset of the plurality optical channels within a second range of wavelengths less than the first range of wavelengths. The second tunable filter is configured to pass a particular channel within the first set of optical channels from the second optical network to the first customer location.
