US Patent 7493044 Methods and apparatus for transmitting data

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.
