CBO QSFP Direct-Attach Copper Cable MC2210126-005-BL 5 m, QSFP+ Male–Male, 40 Gbit/s

BlueOptics CBO QSFP Direct-Attach Copper Cable MC2210126-005-BL is a passive QSFP+ Male–Male copper assembly with a 5 m length and support for up to 40 Gbit/s aggregated data throughput. It is intended for short-range, high-speed interconnects between devices with QSFP interfaces, such as switches, routers and servers. The cable provides a fixed, low-latency wired link suitable for data centre and rack-to-rack connections where QSFP+ ports are available.

Advantages

This passive direct-attach cable offers a cost-effective alternative to active optical modules for short-distance links while maintaining 40 Gbit/s performance. Its QSFP Male–Male connectors ensure direct compatibility with QSFP+ ports without additional transceivers, reducing component count and simplifying installation. The 5 m length provides flexibility for rack-to-rack cabling within a single equipment room and minimizes signal conversion latency compared with fibre-based transceiver solutions.

Suitable for

• Short-range interconnects between switches and routers with QSFP+/QSFP ports
• Server-to-switch connections in high-density racks
• Top-of-rack and end-of-row 40 Gbit/s links within data centres
• Test lab setups and temporary high-speed connections

Key specifications

• Form factor: QSFP+ Male–Male direct-attach copper cable
• Cable length: 5 meters
• Maximum data rate: 40 Gbit/s
• Type: Passive copper assembly for short-reach links
• Suitable interfaces: Devices with QSFP/QSFP+ ports

How to use

Connect each QSFP male connector to the corresponding QSFP/QSFP+ port on your network devices. Ensure both devices support passive QSFP+ copper direct-attach cables and are configured for 40 Gbit/s links if necessary. Handle the cable by the connector housings when plugging or unplugging to avoid stressing the cable. No additional transceivers, power or configuration changes on the cable itself are required.

Recommendations

Verify port compatibility and vendor support for passive QSFP+ copper cables in your equipment documentation. Use the 5 m length for intra-rack or short inter-rack connections; for longer distances consider optical transceivers and fibre cabling. Keep connectors clean and protect them from mechanical strain to maintain link reliability.
