## Summary description

Passive InfiniBand cable CBO OS6860-CBL-40-BL with QSFP connectors and 0.5 m length. Designed for short-range high-speed interconnects between QSFP-enabled switches, adapters or storage devices. Provides a compact black cable for rack-mounted or dense server environments, simplifying direct connections and reducing insertion points.

## Long description

The InfiniBand cable CBO OS6860-CBL-40-BL QSFP to QSFP 0.5 m is a passive, short-reach copper interconnect designed for high-speed links between QSFP-enabled switches, adapters and storage devices. With a 0.5 m length and compact black jacket, this cable suits dense rack and server environments where space and signal integrity matter. It provides a direct QSFP-to-QSFP connection that simplifies cabling and reduces the need for intermediate transceivers.
Advantages
This passive InfiniBand cable delivers low-latency, high-bandwidth connectivity suitable for short-distance links. Its QSFP-to-QSFP terminations ensure straightforward compatibility with devices that support QSFP modules and ports. The 0.5 m length minimizes excess cable slack in rack-mounted setups and helps maintain tidy cable management. The black outer jacket offers a neutral appearance that integrates with standard server-room installations.
Suitable for
Direct connections between QSFP-enabled network switches in racks
High-performance computing clusters and server interconnects
Direct attach links between adapters and storage arrays
Short-distance links inside data centre cabinets and server enclosures
Key specifications
Cable type: passive copper direct-attach
Connector type: QSFP to QSFP
Length: 0.5 m
Colour: black
Application: short-range, high-speed InfiniBand interconnects
How to use
Insert each QSFP connector into the corresponding QSFP port on the devices to be linked, ensuring connectors are fully seated and retention latches engage. No external power or configuration is required for passive operation; devices should recognise the physical link and negotiate speed and protocol automatically according to their capabilities. Avoid sharp bends and excessive pulling forces during installation to preserve signal integrity.
Usage recommendations
For best performance, use this 0.5 m cable in short, direct connections within the same rack or adjacent racks. Verify device compatibility with QSFP passive direct-attach cables and ensure port firmware and drivers are up to date. Maintain cable bend radius and avoid routing near high-interference equipment.
