Abstract
A bypass switch wherein a spherical reflector is movable between first and second positions relative to an array of optical transceivers, at locations, designated the 'S' (source), 'D' (detector), 'I' (input fiber), 'O' (output fiber), and 'L1' and 'L2' (first and second loop) locations. An optical fiber ('loop fiber') has its ends registered at the L1 and L2 locations. The six optical transceiver terminal locations are characterized by first and second symmetry points. The first symmetry point is midway between the S and O locations and midway between the I and D locations. The second symmetry point is midway the I and O locations, midway between the S and L2 locations, and midway between the L1 and D locations. In the first reflector position, the center of curvature is coincident with the first symmetry point. In the second reflector position, the center of curvature is coincident with the second symmetry point. A simple geometric configuration has the six transceiver locations equidistantly spaced along a line (S, D, I, O, L1, L 2), with the first symmetry point between the D and I locations and the second between the I and O locations.
