1024×1024 Optical Switch System
This very-large-scale optical switching system is modularly assembled from LW-64 chips, using an input layer, full-connect layer, and output layer to meet dense interconnection needs such as AI large-model training. Details: System scale: 1024×1024 fully cross-connected channels. Core components: 16 LW-64 chip modules in the input layer and 16 in the output layer; an optical backplane implements the full-connect layer. Interfaces: MTP pigtails, MPO adapters (2048), and MTx64 at input/output. Fiber: single-mode (SM Fiber). Modules: 16 Tx fiber-shuffle groups and 16 Rx fiber-shuffle groups. Unit boards: Each module contains 16 components, supporting 16ch MT×4 interfaces and 64ch FA (fiber assemblies). Protocols: SDN (software-defined networking), with traffic engineering (TE) and topology engineering (ToE).
