摘　　要：报道了一种采用多个4×4,一个8×8光开关以及固定波长转换器组成的大容量全光波长交叉交换连接器(OWXC)的新颖结构,可以实现低串扰、低延迟的无阻塞光信号交换和转换,降低成本30%左右。同时,提出了应用于该结构的智能控制信号传输帧结构以及通过设置可用波长被锁定的时间门限来实现三种具有服务等级的智能光链路建立方式。实验结果显示,一条光链路从被断开到自动重新建立的时间是22 ms,可以实现人工、自动和半自动三种链路建立方式以及三根光纤,24个波长的全无阻塞交换,交换容量达到960 Gb/s。对组建大容量的光交叉连接(OXC)具有参考意义。Based on 4 × 4 and 8× 8 optical switches and static wavelength converters in a novel optical switch matrix, a large capacity intelligent all optical wavelength cross and converter connect （OWXC） is proposed. It can realize a low crosstalk and low delay zero-blocking probability for a link setup which can reduce cost to 30}{. In the intelligent control software, a very simple control frame for control information transportation is proposed along with an optical link setup method by using three kinds of resource lock threshold to realize a classification of service （COS） of link estahlishment. The experiment shows that the time from a link blocking to establishing is 22 ms. And it can realize automatic, selPautomatic and human modes three link establishment methods. The whole cross capacity is 960 Gb/s with three fibers and 24 wavelengths and zero-blocking probability which is very useful for automatic switching optical network （ASON）.
