通过对常见光交叉连接器（OXC）的改进，提出了一种具有有限波长转换能力的内部光交叉连接节点（L-WIXC），既具备冲突消解能力又降低成本。采用算法编程方法，分析比较了L-WIXC和其他两种现有OXC结构，以及基于不同信令协议的L-WIXC的拥塞性能，结果表明L-WIXC具有较低的拥塞概率，并且基于JET协议的L-WIXC比基于JIT协议的L-WIXC具有更低的拥塞概率。通过搭建L-WIXC仿真平台，测试信号光功率、串扰、误码率、眼图等性能参数，分析讨论了单个L-WIXC节点，以及基于L-WIXC节点的线状网络和网状网络的仿真测试结果。结果表明L-WIXC具有良好的联网性能。

A novel optical cross connection named limited wavelength conversion wavelength interchangeable cross connection (L-WIXC) is proposed to improve the conflict resolution and decrease the cost. The optical architecture and network control system of L-WIXC as well as corresponding control algorithm are described. By means of comparing congestion properties of several different OXC structures and different signaling protocols, it can be concluded that the congestion of L-WIXC is lower, and L-WIXC with JET protocol has better congestion probability than that with JIT protocol. A simulation platform is also built for testing the performance of L-WIXC. The tests are done and analyzed for single L-WIXC node, serial links with L-WIXC and mesh links with L-WIXC by simulating the optical power, crosstalk, BER and eye diagram. The results show that L-WIXC has satisfying performance for applying in optical switching networks, especially in optical burst switching network.
