Abstract

一种光交叉互连节点(300)和光信号交换的方法。该光交叉互连节点(300)包括：第一光切换开关(301)、第二光切换开关(302)、下波波长交换开关(303)、上波波长交换开关(304)和穿通维度交换开关(305)，第一光切换开关(301)接收光信号，光信号包括第一光信号和/或第二光信号，将第一光信号发送到下波波长交换开关(303)，将第二光信号发送到穿通维度交换开关(305)；下波波长交换开关(303)对第一光信号进行波长交换；上波波长交换开关(304)对本地生成的第三光信号进行波长交换，并将进行波长交换后的第三光信号发送到第二光切换开关(302)；穿通维度交换开关(305)对第二光信号进行维度交换并发送到第二光切换开关(302)。该光交叉互连节点(300)避免了上下波共享一个波长交换的光开关，能够减少光交叉互连节点(300)的串扰。
