## Summary description

This CBO InfiniBand passive direct-attach copper (DAC) cable QFX-QSFP-DAC-1M-BL is a 1 m QSFP+ to QSFP+ assembly designed for short-distance high-speed connections between switches, servers and storage. As a passive DAC it provides low-latency, energy-efficient connectivity without transceivers, suitable for rack-to-rack or within-rack links in data centers and HPC environments.

## Long description

This CBO InfiniBand passive DAC Cable QFX-QSFP-DAC-1M-BL is a 1 m QSFP+ to QSFP+ direct-attach copper assembly engineered for short-distance, high-speed interconnects. Designed to link switches, servers and storage within racks or between adjacent racks, the passive DAC offers a low-latency, energy-efficient alternative to active optics by eliminating separate transceivers. The cable supports InfiniBand and QSFP+ interfaces and is suitable for data center and high-performance computing (HPC) environments where dense, reliable connections are required.
Advantages
The passive design reduces power consumption and heat generation compared with transceiver-based links while maintaining minimal latency. A one-meter length provides a compact, neatly routed connection for within-rack or adjacent-rack setups. Compatibility with QSFP+ ports simplifies deployment across compatible switches, servers and storage systems. The cable’s copper construction offers robust physical durability for repeated insertions and secure link stability in high-density racks.
Suitable for
Short-distance connections between switches and servers within a rack
Rack-to-rack links in adjacent cabinets
High-performance computing clusters requiring low-latency interconnects
Storage area networks and SAN fabrics using InfiniBand or QSFP+ ports
Key specifications
Connector type: QSFP+ to QSFP+
Length: 1 meter
Media: Direct-attach copper (passive)
Intended use: Short-reach, high-speed interconnects
Typical applications: Data center, HPC clusters, SAN
How to use
Install the cable by inserting each QSFP+ end into the corresponding QSFP+ port on your switch, server or storage device until the latch engages. Ensure devices are powered down or follow hot-plug procedures recommended by the equipment vendor when connecting or disconnecting. Verify link status through the device management interface or LEDs to confirm successful negotiation. Use the 1 m length to route the cable cleanly inside racks or between adjacent cabinets to avoid strain on connectors.
Usage recommendations
For reliable performance, use the cable within the specified short-reach environment and avoid sharp bends or excessive pulling. Confirm compatibility with your equipment’s QSFP+ and InfiniBand implementations and check port settings for speed and lane configurations where applicable.
