Description

一种集成型全光交换节点Integrated all-optical switching node

技术领域Technical field

本发明涉及通信技术领域，尤其涉及一种集成型全光交换节点。The present invention relates to the field of communications technologies, and in particular, to an integrated all-optical switching node.

背景技术Background technique

光通信网络主要由传送网，交换网，接入网三个部分组成，当下，高清视频、云计算等高带宽需求业务的增长，给光通信网络带来了巨大的带宽挑战，由于现有的光通信网络为光电混合网络，而光电混合网络中的网络节点在进行信息交换时，需要对光信号进行光/电、电/光转换，导致交换吞度量和功耗的受到限制，成为交换网的一大瓶颈，为了解决这一问题，人们提出了全光网AON(All Optical Network)的概念。The optical communication network is mainly composed of three parts: the transmission network, the switching network and the access network. Nowadays, the growth of high-bandwidth demand services such as high-definition video and cloud computing brings huge bandwidth challenges to the optical communication network due to the existing The optical communication network is an opto-electric hybrid network, and the network nodes in the opto-electric hybrid network need to perform optical/electrical/electrical/optical conversion on the optical signals during the information exchange, which leads to restrictions on the switching and measurement and power consumption, and becomes a switching network. In order to solve this problem, the concept of All Optical Network (AON) has been proposed.

全光网中的全光交换节点基于波长路由光交换技术，在光域上实现信息的高速交换，数据信号从源节点到目的节点的整个传输过程中始终使用光信号，无需进行光/电、电/光转换，这样，网内光信号的流动就没有光电转换的障碍，交换吞吐率高、功耗低。The all-optical switching node in the all-optical network is based on the wavelength-routed optical switching technology, and realizes high-speed exchange of information in the optical domain. The optical signal is always used during the entire transmission process of the data signal from the source node to the destination node, and no optical/electrical, Electric/optical conversion, in this way, there is no obstacle to photoelectric conversion in the flow of optical signals in the network, and the exchange throughput is high and the power consumption is low.

为了构造全光交换节点，现有技术中采用光开关矩阵拼接而成，称为集成型全光交换节点，然而在实际应用中发现，当输出下波光信号占用的输出端所连接的光纤方向，为穿通光信号请求穿通到的光纤方向时，将出现穿通阻塞。如图1为一种现有的集成型全光交换节点，该全光交换节点中包括第一光开关组101、第二光开关组102和第三光开关组103，当从该第一光开关组101的输入端1输入的下波光信号从该第一光开关组的输出端2输出时，若该第一光开关组输入的穿通光信号请求穿通至该输出端2连接的光纤方向时，由于该下波光信号占用了该输出端2，导致穿通光信号无法从该输出端2输出，从而出现穿通阻塞。In order to construct an all-optical switching node, the optical switch matrix is spliced in the prior art, which is called an integrated all-optical switching node. However, in practical applications, when the output optical fiber is connected to the output end of the optical fiber, A punch-through blockage occurs when the through-light signal is requested to pass through the fiber direction. FIG. 1 is a conventional integrated all-optical switching node, where the all-optical switching node includes a first optical switch group 101, a second optical switch group 102, and a third optical switch group 103. When the lower-wave optical signal input from the input end 1 of the switch group 101 is output from the output end 2 of the first optical switch group, if the through optical signal input by the first optical switch group is requested to pass through to the optical fiber direction connected to the output terminal 2 Since the lower wave optical signal occupies the output terminal 2, the through-light signal cannot be output from the output terminal 2, and a punch-through blockage occurs.
