Product information

Description

The StarTech QSFP40GPC3M is a high-performance 3-meter passive direct attach copper (DAC) cable engineered for 40GbE networking environments. Featuring QSFP+ connectors on both ends, this twinax cable provides a reliable and energy-efficient solution for high-speed data transmission between network switches, servers, and storage devices. As an MSA-compliant, uncoded cable, it ensures broad compatibility with a wide range of networking hardware, making it an ideal choice for data center connectivity where performance and cost-effectiveness are critical.

Advantages

This passive twinax cable offers a significant cost advantage over traditional fiber-optic setups by utilizing copper technology for short-to-medium distance connections. Its low-power design helps reduce overall energy consumption in dense rack environments. The hot-swappable nature of the cable allows for seamless upgrades and maintenance without the need to power down network equipment, thereby minimizing downtime. Furthermore, the robust construction ensures signal integrity for high-speed 40 Gbps data transfers, backed by a lifetime warranty for long-term peace of mind.

Suitable for

  • Connecting network switches within the same rack
  • Linking servers to top-of-rack switches
  • High-speed data center interconnects
  • Short-range 40 Gigabit Ethernet network deployments

When it may not be suitable

This cable is not suitable for long-distance networking applications, as passive copper technology is limited by signal attenuation over distances exceeding a few meters. It is also not intended for use in environments requiring fiber-optic isolation or where electromagnetic interference might be a concern over very long cable runs.

Key specifications

  • Cable length: 3 meters
  • Connector type: QSFP+ to QSFP+
  • Data rate: 40 Gbps
  • Cable type: Passive Direct Attach Copper (DAC) Twinax
  • Weight: 0.252 kg
  • Color: Black

How to use

To install the cable, simply align the QSFP+ connector with the corresponding port on your network switch or server. Insert the connector firmly until it clicks into place. Because the cable is hot-swappable, you do not need to turn off your hardware to perform the installation. Ensure that the cable is not bent beyond its minimum bend radius to maintain optimal signal performance. Once connected, the link should be automatically detected by your networking equipment.

What to consider before purchase

  • Verify that your networking equipment supports 40G QSFP+ ports.
  • Ensure the 3-meter length is sufficient for your specific rack layout.
  • Confirm that your hardware is compatible with MSA-compliant uncoded cables.

Usage recommendations

For optimal performance and longevity, avoid placing heavy objects on the cable and ensure that the cable is routed through proper cable management systems to prevent strain on the connectors.
