CBO Cable MC2210126-004 5m QSFP Male to Male 40 Gbit/s

The CBO Cable MC2210126-004 5m QSFP Male to Male 40 Gbit/s is a direct-attach copper cable intended for short-reach high-speed interconnects. With QSFP male connectors on both ends and a fixed 5 m length, it delivers a low-latency, high-bandwidth link for connections between compatible QSFP ports in switches, routers and network adapters. This cable is designed to provide stable 40 Gbit/s connectivity for rack-to-rack or chassis-to-chassis installations where a short, reliable copper connection is required.

Advantages

This direct-attach cable offers a compact, fixed-length solution that eliminates the need for separate transceivers and patch cords, reducing complexity and component count. The QSFP male-to-male configuration supports high aggregate throughput with low latency and predictable signal integrity over short distances. The cable’s construction prioritizes mechanical robustness for repeated insertion and reliable electrical performance suitable for data centre topologies.

Suitable for

• Short-reach connections between QSFP-enabled switches and routers within the same rack or adjacent racks
• High-speed links between network adapters and top-of-rack switches
• Chassis-to-chassis interconnects in modular systems
• Situations where fixed-length, low-latency copper cabling is preferred over fibre for costs or power considerations

Key specifications

• Connector type: QSFP male to QSFP male
• Maximum data rate: 40 Gbit/s aggregate
• Cable length: 5 metres
• Media type: Direct-attach copper (DAC)
• Intended reach: Short-reach, rack-to-rack or chassis-to-chassis
• Typical use: High-density server and switch interconnects

How to use

Install the cable by inserting each QSFP male connector into compatible QSFP ports on the devices to be linked, ensuring alignment and a firm seating until the connector latches engage. Use the 5 m fixed length to plan port placement and cable routing to avoid unnecessary bends or strain. Verify link status on connected devices and, if required, configure interfaces at 40 Gbit/s or the supported negotiated speed. Disconnect by depressing the connector latch and withdrawing straight out to avoid damaging the ports or cable.

Recommendations

For reliable performance, avoid sharp bends and excessive pulling on the cable; maintain bend radii recommended for copper DAC assemblies and keep the cable within its 5 m intended reach. Use in environments with compatible QSFP ports and verify device compatibility for 40 Gbit/s direct-attach connections before deployment.
