## Summary description

Passive InfiniBand cable from CBO, model CAB-Q-Q-3M-BL, QSFP to QSFP connection with a length of 3 meters. Designed for high-speed data links between QSFP ports in data centers and HPC environments. Provides a reliable physical connection for compatible QSFP interfaces, suitable for short-reach interconnects, server-to-switch or switch-to-switch links.

## Long description

Passive InfiniBand cable from BlueOptics, model CAB-Q-Q-3M-BL is a 3-meter QSFP-to-QSFP direct connection designed for short-reach, high-bandwidth links in data centers and HPC environments. The cable provides a straightforward physical connection between QSFP ports and supports reliable data transfer for server-to-switch, switch-to-switch or device-to-device interconnects where compatible QSFP interfaces are used.
Advantages
This passive QSFP-to-QSFP cable offers low-latency, high-throughput connectivity with minimal power consumption since no active components are required. Its 3 m length balances flexibility and signal integrity for short-reach links in rack and row topologies. The plug-and-play design reduces installation time and complexity, while standardized QSFP connectors ensure broad compatibility with devices that accept QSFP passive copper assemblies.
Suitable for
 Server-to-switch connections in data center racks
 Switch-to-switch short-reach interconnects within the same rack or adjacent racks
 High-performance computing clusters requiring InfiniBand QSFP links
 Temporary or permanent point-to-point links where low latency is required
Key specifications
 Interface: QSFP to QSFP passive copper assembly
 Length: 3 meters
 Cable type: Passive InfiniBand cable suitable for short-reach connections
 Use environment: Data center and high-performance computing (HPC) applications
 Latency: Low-latency physical link characteristic of passive copper QSFP connections
How to use
Connect each QSFP connector to the corresponding QSFP port on your devices, ensuring proper orientation and secure seating. Verify that both ends are compatible with the equipment’s QSFP interface and that firmware or driver settings on the devices permit passive copper links. After connection, monitor link status indicators on the devices to confirm successful negotiation and data transfer. For best results, route the cable to avoid sharp bends and mechanical strain.
Usage recommendations
For reliable performance, use this cable for short-reach connections within racks or between adjacent racks. Avoid excessive bending radii and exposure to mechanical stress. Confirm device compatibility with passive QSFP copper assemblies and, when deploying in dense installations, plan cable routing to maintain airflow and access to ports.
