Abstract
The present invention comprises a shifting unit that uses optical fibers to shift beams among various outputs. The shifting unit comprises a shifting entrance plane and a shifting exit plane. The shifting entrance plane comprises at least one row of signal input positions. Each signal input position is adapted to receive an optical signal from a source. The shifting exit plane comprises a respective number of rows of signal output positions. Each signal output position is adapted to output an optical beam. Each signal input position of a given row is connected by an optical fiber to a corresponding signal output position. Also, each optical fiber is the same length as every other optical fiber in the shifting unit. The present invention also comprises methods and apparatus comprising the shifting unit.
