1.Product Overview

TNU2CTU is a high-performance enhanced classical optical interconnect research and integration platform designed for the integration requirements of hundred bit and more complex quantum computing prototype systems on the OSN 9800 series optical transmission platform.As an advanced version of TNU1CTU, this product has been comprehensively enhanced in terms of channel density, timing performance, system integration, and programmability, aiming to provide a solid and reliable classical control and data network foundation for building quantum computing prototype systems close to practical scale, and solve the core interconnect engineering challenges brought by quantum bit scale expansion.

2.Core Enhancement Features and Engineering Positioning

High density channel expansion capability

Support a significant increase in the number of independent control and data channels (such as 32 or more) to meet the exponential growth demand for parallel control channels in hundred bit quantum processors.

By adopting higher integration optoelectronic devices and advanced packaging technology, the channel density can be doubled in a compact space, supporting the integration of large-scale systems.

Sub nanosecond global synchronization and extremely low jitter performance

Integrate a new generation of high-precision synchronous distribution engine, improve the timing alignment accuracy between multiple channels to sub nanosecond level (<500 ps), and further reduce the additional time jitter of single channels.

Support more complex synchronization topologies (such as master-slave and hierarchical synchronization) to meet the collaborative operation requirements between distributed quantum computing modules.

Enhanced signal integrity assurance

Adopting more advanced equalization and pre emphasis techniques to optimize the waveform fidelity of high-frequency control signals (such as fast microwave pulses used for superconducting qubits) after long-distance optical electrical optical conversion.

Enhanced anti-interference design and better noise figure ensure that weak quantum measurement signals can be transmitted back with high signal-to-noise ratio in complex laboratory electromagnetic environments.

Deep System Integration and Collaborative Interface

Provide hardware interfaces and software drivers for deeper collaboration with mainstream commercial quantum control systems such as Quantum Machines OPX+and Zurich Instruments SHFQA.

Supports more flexible topology configurations (such as multicast, arbitrary point-to-point connections), and can be dynamically reconfigured through the concept of Software Defined Networking (SDN).
