Abstract: In an example embodiment, a method includes receiving a first combined optical signal at an edge filter. The method further includes redirecting, at the edge filter, a second combined optical signal toward a first zigzag demultiplexer; and passing a third combined optical signal through the edge filter toward a light redirector based on wavelength. The method further includes redirecting the third combined optical signal toward a second zigzag demultiplexer. The method may further includes separating, at the first zigzag demultiplexer, the second combined optical signal into a first optical signal on a first optical path and a second optical signal on a second optical path based on wavelength. The method further includes separating, at the second zigzag demultiplexer, the third combined optical signal into a third optical signal on a third optical path and a fourth optical signal on a fourth optical path based on wavelengths.
