CBO InfiniBand QSFP cable QSFP-Cable-1M-BL — 1 m, QSFP to QSFP, black

The CBO InfiniBand QSFP cable QSFP-Cable-1M-BL is a 1 m direct-attach cable with QSFP connectors on both ends, finished in black. Designed for short-range InfiniBand interconnects, this QSFP-to-QSFP cable provides a direct electrical connection for devices with compatible QSFP ports, supporting low-latency and high-throughput links commonly required in data centers, HPC clusters and storage networks.

Advantages

This QSFP cable offers a compact, single-cable solution for linking QSFP ports without additional transceivers, reducing equipment complexity and rack space. The 1 m length minimizes signal loss and is suitable for top-of-rack or within-rack connections. Its QSFP-to-QSFP direct-attach design supports stable low-latency performance and efficient power usage compared with separate transceiver and fiber assemblies.

Suitable for

• Short-range interconnects between QSFP-enabled switches and servers
• High-performance computing (HPC) cluster node connections
• Storage area network (SAN) links and server-to-storage connections
• Top-of-rack and within-rack cabling in data centers

Key specifications

• Length: 1 metre
• Connector type: QSFP to QSFP (direct-attach)
• Cable color: black
• Application: Short-reach InfiniBand interconnects for data center and HPC environments
• Performance focus: Low latency, high throughput for clustered and storage networking

How to use

Install the cable by firmly inserting each QSFP connector into the corresponding QSFP port on two compatible devices until the connector latch engages. Ensure both devices are powered down or that hot-plugging is supported by the equipment before insertion or removal. After connection, verify link status and negotiated speeds through the devices' management interfaces or LEDs. Use the 1 m length for short, direct connections within a rack or between adjacent racks as appropriate.

Usage recommendations

Route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius specified by the equipment manufacturer. For reliable operation, match the cable to compatible QSFP ports and verify device firmware supports direct-attach copper QSFP links where applicable. Store unused cables in a dry, dust-free environment to preserve connector integrity.
