摘要
OADM节点是WDM光网络的关键节点之一。研究了OADM节点的实现方法,提出了一种设计方案,并讨论了光上下路开关阵列的驱动和监控的软硬件制作,完成了下路光功率监测的电路设计以及软件设计。分析了OADM节点保护倒换的原理和节点中的串扰问题。
The OADM node is one of the key instruments used in WDM optical networks.The structure of an OADM node is illustrated,the mechanism of protection switch and the crosstalk in it is analyzed.How to design the hardware and software for driving and monitoring the OADM node,especially for its add-drop optical switch array are shown.And it also shows the circuit design and software design for the optical drop power detects.Add-drop multiplexing boards are finished and used to fulfill OADM functions.These will be used in the OADM node and OXC node of CAINONET.
