Apparatus and method for switching optical transmission lines.

A switching device transmission line comprises A plugboard FIBER OPTIC (22) TO CATCH A PLURALITY OF FIRST FIBER OPTICS (12), a mounting board FIBER OPTIC (24) ARRANGED SEPARATE BOARD CONNECTION WITH AMONG THEM default spacing in the horizontal direction, TO CATCH A FIBER OPTIC second plurality (16), and a robot to handle the second fibers. EVERY SECOND FIBER OPTIC AL plugboard (22) extends through mounting board (24) and the distal end of the second optical fiber ES DESECHABLEMENTE KINGDOM TO plugboard (22) to be selectively connected to one of THE first optical fibers. WHEN THE END OF THE SECOND DISTAL FIBER OPTIC IS ATTACHED TO plugboard (22), the second optical fiber is extended laterally LOOSENED STATE BETWEEN THE TWO BOARDS. In this state, Netter OF THE SECOND UNITED FIBER OPTICS NEAR THE TWO BOARDS ARE scarcer than those in the middle ground between the two boards. THUS, THE ROBOT can easily handle the second optical fiber.
