Network Cable MaxLink ML-DAC40G+2 QSFP+ 40G 2m Black

The MaxLink ML-DAC40G+2 is a high-performance 2-meter QSFP+ direct attach copper (DAC) cable engineered for high-speed networking environments. Designed to support 40G Ethernet and InfiniBand standards, this passive cable provides a reliable, low-latency connection for data centers, enterprise networks, and high-performance computing clusters. Its robust construction and flexible design ensure easy installation in dense rack environments, while the black finish maintains a clean, professional aesthetic in any server room.

Advantages

This passive copper cable offers an energy-efficient solution for short-reach interconnections, as it does not require active power components, thereby reducing overall power consumption and heat generation within the rack. The high-quality shielding and precision-engineered QSFP+ connectors ensure signal integrity and minimal data loss during high-speed transmission. Its 2-meter length provides sufficient reach for top-of-rack switching applications, and the flexible cable jacket allows for efficient cable management in tight spaces without compromising performance.

Suitable for

• Connecting 40G switches to servers
• High-speed data center interconnections
• InfiniBand networking clusters
• Top-of-rack (ToR) switch-to-switch links

This cable is not suitable for long-distance connections, as passive DAC technology is limited to short-reach applications. It is also not compatible with devices that do not feature a QSFP+ port, and it cannot be used for applications requiring active signal amplification over extended distances.

Key specifications

• Connector type: QSFP+
• Cable length: 2 meters
• Data rate: 40 Gbps
• Cable type: Passive copper (DAC)
• Color: Black

How to use

To install the cable, ensure that both the switch and the server ports are powered on or ready for connection. Align the QSFP+ connector with the port on your networking equipment and insert it firmly until the locking mechanism clicks into place. The connection is plug-and-play, meaning the network interface should automatically detect the link once the cable is securely seated. 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 hardware supports QSFP+ 40G interfaces
• Ensure the 2-meter length is sufficient for your specific rack layout
• Check compatibility with your switch manufacturer's requirements

Usage recommendations

For optimal performance and longevity, avoid bending the cable beyond its minimum bend radius and ensure that the connectors are kept free of dust and debris. Always support the weight of the cable to prevent strain on the port connections.
