Lenovo 0.5m Intel OPA 100 Series Passive Copper QSFP28 Cable

Overview

The Lenovo 00WE031 is a 0.5 meter passive copper QSFP28 cable designed specifically for Intel OPA 100 Series hardware. It provides a reliable, high-speed connection between servers, storage devices, and switches within the same rack or between adjacent racks. Its passive design means it contains no active electronics, which helps reduce latency and power consumption while maintaining signal integrity for short-distance data transmission.

This cable is ideal for data centers and high-performance computing environments where space is limited and airflow is critical. Its compact length minimizes cable clutter and supports efficient rack organization, making it a practical choice for upgrading or expanding network infrastructure.

Key features

• Passive copper construction that eliminates the need for power and reduces potential points of failure
• QSFP28 connectors on both ends with secure latching to ensure stable connections in dense setups
• Short 0.5 meter length designed to fit neatly inside racks or between adjacent racks without excess slack
• Direct attach cable suitable for connecting servers, switches, and storage devices in high-speed networks
• Plug-and-play installation simplifies deployment and maintenance in complex data center environments

Key specs

• Length: 0.5 meter (1.64 feet)
• Connector type: QSFP28 male to QSFP28 male
• Cable type: Passive copper
• Compatibility: Intel OPA 100 Series hardware

Connectivity and compatibility

This cable is designed to work seamlessly with Intel OPA 100 Series devices, providing a direct attach connection that supports high-speed data transfer within racks. The QSFP28 connectors ensure compatibility with a wide range of network switches, servers, and storage nodes that use this interface standard. Its passive design means it relies on the host devices for signal conditioning, which helps maintain low latency and power efficiency.

Ideal uses and environments

The Lenovo 00WE031 fits well in data centers and high-performance computing clusters where short, reliable connections are needed between devices in close proximity. It is particularly useful for top-of-rack switch connections, server clusters, and storage arrays where cable management and airflow are priorities. This cable is a strong choice for IT professionals looking to maintain clean, efficient network setups without the complexity or cost of active optical cables.
