A method of transmitting data includes receiving a plurality of downstream
wavelength streams from a first optical fiber, each wavelength stream
corresponding to a separate downstream data transmission, passing all
downstream streams but at least one downstream targeted-wavelength stream
to a second optical fiber, and routing the downstream targeted-wavelength
stream to a subscriber on a third optical fiber, wherein the first
optical fiber, the second optical fiber, and the third optical fiber are
connected to a single device, and wherein the third optical fiber is a
drop cable.
