Abstract
A system and method of asymmetrical fiber or waveguide spacing comprising, in general, an asymmetrical fiber concentrator array (FCA), wherein an offset in the front face spacing of the output waveguides relative to the input waveguides functions to reduce or eliminate the introduction of static back reflection, and static in-to-in crosstalk into a fiber by an optical switch, but does not impose the cost, complexity, and insertion loss penalties brought about by additional components.
