Delock Twinax Cable QSFP+ to QSFP+ 40 Gbps 2 m

The Delock Twinax cable is a high-performance solution designed for rapid data transmission between networking devices equipped with QSFP+ ports. Measuring 2 meters in length, this passive direct attach copper cable facilitates stable and efficient connectivity for high-bandwidth applications. It is engineered to support data rates of up to 40 Gbps, making it a reliable component for modern network infrastructures.

Advantages

This cable offers a cost-effective alternative to optical transceivers for short-distance connections, as it eliminates the need for additional modules. Its passive design ensures low power consumption and minimal latency, which is critical for maintaining high-speed data flow in demanding environments. The robust construction provides durability and consistent signal integrity, ensuring that your network equipment operates at peak performance without unnecessary signal degradation.

Suitable for

• Connecting switches and routers in data centers
• High-speed server-to-server communication
• Short-range network links within server racks
• High-bandwidth storage area networks

When it may not be suitable

This cable is not intended for long-distance networking, as passive copper technology is limited by signal attenuation over extended lengths. It is also not compatible with devices that do not feature QSFP+ ports, and it cannot be used as a direct replacement for fiber optic cables in environments requiring long-reach connectivity.

Key specifications

• Connector type: QSFP+ to QSFP+
• Data transfer rate: Up to 40 Gbps
• Cable length: 2 meters
• Cable type: Passive direct attach copper (DAC)
• Application: High-speed networking

How to use

To use the cable, simply insert the QSFP+ connector into the corresponding port on your networking hardware until it clicks into place. Ensure that both devices are powered on and configured to support 40 Gbps speeds. The cable is hot-swappable, allowing for installation or removal without shutting down the connected equipment, provided the hardware supports this feature.

What to consider before purchase

• Verify that your networking equipment supports the QSFP+ standard
• Measure the required distance between devices to ensure 2 meters is sufficient
• Check the compatibility list of your switch or server manufacturer

Usage recommendations

For optimal performance, ensure that the cable is not bent beyond its minimum bend radius and is kept away from sources of electromagnetic interference. Regularly inspect the connectors for dust or debris to maintain a clean signal path.
