The QSFP28 passive copper cable[1] contains four high-speed copper pairs, each operating at data rates of up to 25Gb/s. Each QSFP28 port comprises an EEPROM providing product information, which can be read by the host system.

NVIDIA unique-quality cable solutions provide power-efficient connectivity for short distance interconnects. It enables higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers.

Rigorous cable production testing ensures best out-of-the-box installation experience, performance and durability.

LinkX cables and transceivers are often used to link top-of-rack switches downwards to network adapters in NVIDIA GPUs and CPU servers, and storage and/or upwards in switch-to-switch applications throughout the network infrastructure.

The latest rapid growth in data center traffic and cloud computing has resulted in tremendous increases in machine-to-machine traffic due to rapid adoption of server virtualization, software-defined networks (SDNs), and in-cloud computing. Now add the massive bandwidth requirements for networking terabytes of data for training Artificial Intelligence (AI) machine learning (ML) GPU-based systems.

This is driving massive demands for high-bandwidth and low-latency networks. High-speed DAC and AOC cables and optical transceiver interconnects are playing a critical role in these modern data center technologies.

NVIDIA® LinkX® Ethernet DAC cables are the lowest-cost way to create high-speed 100G–400G links in Ethernet switching networks and for NVIDIA GPU-based systems. DACs are widely used in data centers to connect servers and GPU compute systems to the top-of-rack (TOR) switches and link spine-to-superspine switches inside racks over short cable lengths.
