Abstract: An example optical cross-connect architecture includes at least one front inserting board and at least one rear inserting board, where each front inserting board is orthogonal to any rear inserting board, one side of each front inserting board is disposed opposite to one side of any rear inserting board, all of the at least one rear inserting board is located on one side of any front inserting board, and each front inserting board is pluggably connected to any rear inserting board. An optical signal distribution module is disposed in the at least one front inserting board, and/or an optical signal distribution module is disposed in the at least one rear inserting board.

Abstract: The technology of this application relates to an optical backplane interconnection apparatus that may include at least one optical backplane and at least one board. One side surface of each optical backplane is disposed opposite to one side surface of any board. All boards are located on a same side of any optical backplane. Each optical backplane is pluggably connected to any board. In embodiments of this application, the optical backplane is connected to any board by using only one side surface, so that a position of the optical backplane is not limited by another component. In this way, the optical backplane can be pluggably connected to the board. When the optical backplane is faulty, the optical backplane can be replaced separately without replacing an entire cabinet. In addition, each optical backplane is configured to be pluggably connected to any board, so that the optical backplane can be replaced more flexibly and more easily.
