CBO InfiniBand cable XLDACBL3-BL 3 m QSFP black

The CBO InfiniBand cable XLDACBL3-BL 3 m QSFP black is a passive high-speed cable designed to connect equipment with QSFP interfaces over a short distance. It provides a direct link between switches, servers, storage arrays and compute nodes in data center and cluster environments where low-latency, high-throughput connections are needed. The cable's 3 metre length and QSFP terminations make it suitable for top-of-rack or mid-row cabling runs that require reliable physical interconnects without active components.

Advantages

This passive InfiniBand cable supports high data rates typical for QSFP interfaces while avoiding the need for external transceivers, reducing power consumption and component count. The fixed 3 m length simplifies planning for short inter-rack or intra-rack connections and the robust black jacket offers physical protection in dense cable environments. Compatibility with standard QSFP ports enables straightforward plug-and-play installation between compatible network and compute devices.

Suitable for

• Direct links between QSFP-equipped switches and servers
• Interconnects for cluster nodes in high-performance computing
• Short-distance connections to storage arrays and SAN equipment
• Top-of-rack and mid-row cabling in data center racks

Key specifications

• Connector type: QSFP terminations at both ends
• Length: 3 metres
• Cable type: Passive InfiniBand copper/compatible with QSFP ports
• Color: Black outer jacket
• Application: Short-reach high-speed interconnects for data center and cluster environments

How to use

Inspect the cable and connectors before installation to ensure there is no visible damage. Align the QSFP connector with the device port, insert the connector until it seats securely and confirm the connection with device port LEDs or management interfaces. Avoid sharp bends and maintain the manufacturer's recommended minimum bend radius. For removal, press any release mechanism on the connector housing (if present) and pull straight out to prevent stress on the port.

Usage recommendations

Use this cable for short, direct QSFP connections within racks or between adjacent racks. Keep cable runs tidy and supported to prevent strain; avoid routing near high-heat sources and maintain proper airflow in rack environments. Verify port compatibility and supported data rates on both connected devices before deployment.
