光交叉连接技术光交叉连接是全光网络的核心技术,也是全光网络技术中最难解决的“瓶颈”问题。在理想的全光网中,信号从源节点到目的节点均是在光的范畴内进行,但是由于现有器件技术的限制,使得全光网中各节点的处理能力有限,并不能完成光波转换及存储等功能,而这些功能对于全光网有效地运行具有很重要的意义。因此人们从实用的角度出发,提出了有限制地在节点上使用电处理的策略,即用电处理来完成现在光处理所不能完成的功能,从而使全光WDM网的运行使用的能力和范围得到充分的扩展。
Optical cross-connect technology Optical cross-connect is the core technology of all-optical network, but also the most difficult bottleneck in all-optical network technology. In the ideal all-optical network, the signal from the source node to the destination node are in the light of the category, but due to the limitations of the existing device technology, making all-optical network nodes in the processing power is limited and can not complete the optical conversion And storage and other functions, and these functions for the effective operation of all-optical network has a very important significance. Therefore, people from a practical point of view, put forward a limited use of electric treatment nodes in the strategy that the use of electricity to complete the current optical processing can not be done, so that all-optical WDM network operation and use of the ability and scope Get full expansion.
