BlueOptics QSFP112 Direct Attach Cable for Supermicro CBL-NTWK-0912-QSFP-0.5, 400GBASE-CR4, 0.5 Meter

The BlueOptics QSFP112 Direct Attach Cable is a high-performance networking solution engineered for demanding 400GBASE-CR4 applications and high-speed Infiniband environments. Designed as a direct replacement for the Supermicro CBL-NTWK-0912-QSFP-0.5, this 0.5-meter passive copper cable provides a reliable and efficient connection for modern data center infrastructures. By utilizing high-quality copper conductors, it ensures stable signal integrity and minimal latency for critical server-to-switch interconnects.

Advantages

This cable offers a cost-effective alternative to original manufacturer hardware without compromising on performance or compatibility. Its passive design eliminates the need for external power, reducing overall energy consumption and heat generation within the rack. The robust construction ensures durability during installation, while the precision-engineered QSFP112 connectors provide a secure fit, preventing accidental disconnections and ensuring consistent data throughput in high-density networking environments.

Suitable for

• High-speed server-to-switch interconnects
• Data center rack-to-rack cabling
• Infiniband networking environments
• 400GBASE-CR4 network infrastructure

This cable is not suitable for long-distance connections, as its passive copper design is strictly limited to short-range links up to 0.5 meters. It is also not intended for use in environments requiring fiber optic transmission or where electromagnetic interference levels exceed the shielding capabilities of standard copper cabling.

Key specifications

• Connector type: QSFP112
• Cable length: 0.5 meters
• Data rate: 400 Gbps
• Standard: 400GBASE-CR4
• Cable type: Passive copper

How to use

To install the cable, ensure that both the server and the switch ports are powered on or prepared for hardware insertion. Align the QSFP112 connector with the port on your networking equipment and push it firmly until the locking mechanism clicks into place. No additional configuration or software drivers are required, as the cable is recognized automatically by the host device. To remove the cable, pull the release tab on the connector to disengage the lock before gently sliding it out of the port.

What to consider before purchase

• Verify that your networking equipment supports the 400GBASE-CR4 standard.
• Ensure the 0.5-meter length is sufficient for your specific rack layout.
• Confirm compatibility with your existing Supermicro hardware environment.

Usage recommendations: Always handle the cable by the connector housing rather than the wire to prevent internal damage. Ensure that the cable is routed with a sufficient bend radius to maintain signal integrity and prevent strain on the ports.
