An adaptive gridless OXC is implemented using a 3D-MEMS optical backplane plus optical modules (sub-systems) that provide elastic spectrum and time switching functionality. The OXC adapts its architecture on demand to fulfill the switching requirements of incoming traffic. The system is implemented in a seven-node network linked by installed fiber and is shown to provide suitable architectures on demand for three scenarios with increasing traffic and switching complexity. In the most complex scenario, signals of mixed bit-rates and modulation formats are successfully switched with flexible per-channel allocation of spectrum, time and space, achieving over 1000-fold bandwidth granularity and 1.5 Tb/s throughput with good end-to-end performance.
一种自适应无网格光交叉连接器（OXC）通过三维微机电系统（3D-MEMS）光学背板加光学模块（子系统）实现，这些光学模块提供弹性频谱和时间交换功能。该OXC可根据需求调整其架构，以满足传入流量的交换要求。该系统在一个由已安装光纤连接的七节点网络中实现，并被证明能够根据需求为三种流量和交换复杂度不断增加的场景提供合适的架构。在最复杂的场景中，混合比特率和调制格式的信号通过灵活的每通道频谱、时间和空间分配成功交换，实现了超过1000倍的带宽粒度和1.5太比特每秒的吞吐量，同时具备良好的端到端性能。
