D2×2 Mechanical Optical Switch

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).

Standard rack-mount optical switching equipment based on the LW-64 silicon chip supports standalone deployment or stacked expansion. Hardware: LW-64 silicon chip. Channels: 64 fully cross-connected channels. Input/output: LC ports. Dimensions: standard 19-inch, 1U height. Expansion: stacking for scale up/scale out architectures. Options: integrated EDFA (erbium-doped fiber amplifier) and GFF (gain-flattening filter).

Rack-mount optical switches provide all-optical routing, wavelength selection, and self-healing protection in optical switching equipment and systems. They can also operate as slave devices for multichannel optical-device testing and monitoring, offering efficient testing, flexible configuration, and easy upgrades.

A motor-driven optical switch controls and switches optical paths and plays an important role in optical communications. Main applications include multichannel optical monitoring in optical transmission systems, automatic switching of multiple light sources/detectors in LANs, and multipoint dynamic monitoring in optical sensing systems. Optical test systems use it for testing optical fibers, optical devices, networks, and field-installed optical cables, as well as optical-device assembly and alignment.
