## Summary description

Passive InfiniBand cable CBO CBL-QSFP-40GE-PASS-3M-BL with QSFP connectors and a 3 m length. Designed for short-reach, high-throughput links between switches, servers or network adapters that support QSFP interfaces. Provides straightforward connectivity for 40GbE/InfiniBand setups where a passive copper link is acceptable; ideal for rack-to-rack or in-rack connections with minimal configuration.

## Long description

CBO InfiniBand cable CBL-QSFP-40GE-PASS-3M-BL is a 3-metre passive QSFP-to-QSFP copper assembly designed for short-reach, high-bandwidth links. It provides a direct physical connection between devices with QSFP ports and supports 40GbE/InfiniBand signalling where passive copper is suitable. The cable comes in black and is intended for in-rack or rack-to-rack connections that require low-latency, high-throughput data transfer without active signal conditioning.
Advantages
The passive QSFP-to-QSFP construction delivers reliable electrical performance for short distances while eliminating the need for additional transceivers or power. Its 3 m length balances reach and cable management in typical server and switch deployments. Compatibility with standard QSFP interfaces enables plug-and-play installation and predictable signal characteristics for 40GbE and InfiniBand links. The black jacket offers a neutral appearance that blends into standard rack environments.
Suitable for
Direct connections between switches with QSFP ports
Server-to-switch links inside racks
High-bandwidth short-reach InfiniBand or 40GbE links
Rack-to-rack connections within the same equipment row
Key specifications
Connector type: QSFP to QSFP (passive copper)
Cable length: 3 metres
Cable colour: black
Intended use: short-reach high-throughput links
Supported protocols: 40 Gigabit Ethernet and InfiniBand signalling
Form factor: direct attach copper (passive)
How to use
Ensure both devices have compatible QSFP ports and support passive copper direct-attach assemblies for the intended data rate. Route the cable to avoid sharp bends and secure excess length to maintain airflow and accessibility in the rack. Insert each QSFP connector into the corresponding port until the latch engages; no additional configuration is required at the cable level. Verify link status and negotiated speed on the connected equipment and replace or re-route the cable if physical damage or connection issues are detected.
Usage recommendations
Use this passive QSFP cable for short-distance connections where a cost-effective, low-latency copper solution is acceptable. Avoid installations requiring extended reach, active signal conditioning, or electromagnetic isolation; in those cases consider active copper or optical alternatives. Regularly inspect connectors and jacket integrity and follow equipment vendor guidance for maximum supported cable types and lengths.
