LinkX Cable is focused on accelerating data center and artificial intelligence computing systems that not only deliver high data transfer rates, but are also designed to specifically optimize low latency performance to meet the high speed and efficiency requirements of modern computing systems.

I. Main features and technical specifications

1.transmission distance and rate

Data center applications: Support transmission distances up to 2 km, usually within 50 meters.

2.Data transmission rate:

800Gb/s Connected to the switch.

400Gb/s(400G optical modules) is connected to the network adapter and DPU (data processing unit).

II. Low latency and high bandwidth

Low latency: With 100G-PAM4 technology, LinkX cables can still maintain ultra-low latency when transferring large amounts of data, providing a solid guarantee for real-time analysis and decision making.

High bandwidth: Supports high bandwidth applications to meet the requirements of high-speed data transmission.

Low Bit Error Rate (BER) : Optimize design and testing to achieve the lowest bit error rate for low-latency, high-bandwidth applications.

Direct connection: Cross-fiber connects the two transceivers directly, reducing latency along the data transmission path. LinkX products can be seamlessly integrated into Nvidia Quantum InfiniBand and Spectral Ethernet network switches, ConnectX PCIe network adapters, and BlueField PCIe Dpus, creating an efficient and collaborative AI-accelerated ecosystem.

III.The unique advantages of AI-accelerated networks

In terms of accelerating AI computing, Nvidia's networking technology shows significant advantages:

1, Focus on ultra-high data rates and low latency: The product focuses on a small number of components optimized for high data rates and low latency, unlike the complex configuration of hundreds of different components in the traditional IEEE Ethernet cable and transceiver product line.

2. Integrated design and testing: These components are not only designed and manufactured, but also rigorously tested to ensure that they operate optimally in an end-to-end configuration.

IV. Select an InfiniBand cable and optical module

When selecting an InfiniBand cable and optical transceiver module, you need to consider the buffer delay requirements of the switch, optical module performance, and optical fiber delay. This combined consideration helps minimize latency in high-speed systems, which is a key factor in AI-accelerated systems.
