Abstract:
1. An optical network, comprising: 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 passive banded optical filter; and a first customer location coupled to the second optical network by a first tunable filter, wherein the first passive banded optical filter is configured to pass a first set of optical channels from the first optical network to the second optical network, wherein the first set of optical channels comprises a subset of the plurality optical channels within a second contiguous range of wavelengths less than the first range of wavelengths; and wherein the first 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.
