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。
Reported a novel structure of a large-capacity all-optical wavelength cross-connect connector (OWXC) using a plurality of 4 × 4, an 8 × 8 optical switches and a fixed wavelength converter to achieve low crosstalk and low delay non-blocking Optical signal exchange and conversion, reduce costs about 30%. At the same time, the structure of intelligent control signal transmission frame applied to this structure is proposed, and three types of intelligent optical link establishment with service level are realized by setting the time threshold for the available wavelength to be locked. The experimental results show that the time from disconnection to automatic re-establishment of an optical link is 22 ms, which can realize the establishment of artificial, automatic and semi-automatic three kinds of links as well as three optical fibers with 24 non-blocking switching and switching capacity Reaching 960 Gb / s. It has reference meaning to set up large-capacity optical cross connection (OXC).
