## Long description

CBO InfiniBand cable CAB-Q-S-3M-BL QSFP to 4×SFP+ 3 m, black is a 3‑metre passive breakout copper cable that links a single QSFP port to four SFP+ ports. Built for InfiniBand and high‑speed Ethernet environments, the cable delivers a compact, direct physical connection without the need for external adapters or transceivers. Its black jacket and flexible construction suit rack and chassis installations where short-reach, high-density cabling is required.
Advantages
The cable supports direct QSFP-to-4×SFP+ connectivity, simplifying cabling in top-of-rack switches, aggregation switches and server I/O modules. A single assembly replaces multiple individual cables and reduces port conversion complexity. The integrated breakout design minimizes signal loss and maintains the electrical characteristics needed for high-speed InfiniBand and 10 Gigabit Ethernet links. The 3 m length offers flexibility for common rack layouts while avoiding excess slack.
Suitable for
Connecting a QSFP port on a switch or router to four SFP+ ports on servers or expansion modules
Short-reach interconnects within racks or between adjacent racks in data centers
High-density network deployments requiring QSFP to SFP+ breakout without external adapters
InfiniBand and 10 GbE uplinks, aggregation and server connectivity
Key specifications
Connector type: QSFP to 4×SFP+ breakout
Cable length: 3 metres
Cable jacket colour: black
Media type: passive copper breakout assembly for short-reach connections
Supported protocols: InfiniBand and 10 Gigabit Ethernet electrical interfaces
Application: short-distance, high-density rack and chassis interconnects
How to use
Insert the QSFP end into the QSFP port on the source device and plug each SFP+ connector into the respective SFP+ ports on the target devices. Ensure ports are powered down or follow hot‑plug procedures recommended by your hardware vendor if inserting while systems are active. Route the cable to avoid sharp bends and excessive tension; maintain proper bend radius to preserve signal integrity. Verify link status on both devices after installation and adjust port configuration if necessary to enable the intended InfiniBand or Ethernet mode.
Usage recommendations
Use this cable for short interconnects within racks and between adjacent rack units. Confirm compatibility with the switch and server vendor for passive breakout assemblies and check port firmware or BIOS settings when mixing InfiniBand and Ethernet equipment. Store and install the cable in environments within the operating temperature range recommended by your hardware provider, and avoid running the cable alongside high‑power electrical lines to reduce potential interference.
