1. A method for cross connecting optical signals, comprising:
- using a common beam steerer to direct a plurality of optical signals from a plurality input ports to a plurality of output ports;
adjusting a curvature of the common beam steerer so that paths of the plurality of optical signals have substantially the same effective path length; and
fixedly positioning the beam steerer at a predetermined location relative to the ports.

Abstract
A method for cross connecting optical signals includes using a common beam steerer to direct a set of optical signals from a set of input ports to a set of output ports. The method further includes adjusting a curvature of the common beam steerer so that paths of the optical signals have substantially the same effective path length.

11. An apparatus for cross connecting optical signals, comprising:
a common beam steerer adapted to direct a plurality of optical signals from a plurality of input ports to a plurality of output ports, the members of the plurality of input ports and the members of the plurality of outputs ports are each arranged spaced apart from one another on a respective plane, wherein a curvature of the common beam steerer is fixedly set so that paths of the plurality of optical signals have substantially the same effective path length. - View Dependent Claims (12, 13, 14, 15, 16)

17. An apparatus for cross connecting optical signals, comprising:
-
a first plurality of ports, members of the of the first plurality of ports are adapted for at least one of receiving, or transmitting optical signals; a second plurality of ports, members of the second plurality of ports are adapted for at least one of receiving, or transmitting optical signals, and a common beam steerer having a predetermined, fixed curvature wherein the first and second pluralities of ports are positioned relative to the common beam steerer so that a plurality of paths of optical signals transmitted between the members of the first and second pluralities of ports and steered by the common beam steerer has substantially the same effective path length. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 33, 34)
