Performance Specifications of Direct-Attach Breakout Cable

The QSFP-4SFP10G-CU5M= Cisco 5M SFP+ copper Direct-Attach Breakout Cable is a high-performance networking cable designed to support high-speed data transmission in data centers and other high-performance computing environments. Here are some key performance specifications of this cable:

  • Data Transfer Rate: The QSFP-4SFP10G-CU5M= cable supports data transfer rates of up to 40 Gbps, making it ideal for use in high-performance computing environments where speed and reliability are critical.
  • Cable Length: This cable is 5 meters in length, which makes it suitable for connecting devices that are located relatively close to each other. The length of the cable is important because longer cables can cause signal loss and reduce the overall performance of the network.
  • Connector Type: The QSFP-4SFP10G-CU5M= cable features a QSFP connector on one end and four SFP+ connectors on the other end. This design allows the cable to break out the high-speed signals from the QSFP connector into four separate SFP+ connectors, which can be connected to different devices.
  • Cable Type: The QSFP-4SFP10G-CU5M= cable is a copper direct-attach cable (DAC), which means that it uses copper wires to transmit signals. Copper DAC cables are known for their low latency, low power consumption, and low cost compared to fiber optic cables.
  • Compatibility: The QSFP-4SFP10G-CU5M= cable is compatible with a wide range of Cisco networking devices, including switches, routers, and servers. It is important to ensure that the devices you are connecting the cable to are compatible with the cable before making any connections.

Maintenance and Care Tip of 5M SFP+ Cable

The QSFP-4SFP10G-CU5M= is a Cisco 5-meter SFP+ copper direct-attach breakout cable that is designed to connect a 40 Gigabit Ethernet (40GbE) QSFP+ port to four separate 10 Gigabit Ethernet (10GbE) SFP+ ports. Like any other networking component, this cable requires proper maintenance and care to ensure its optimal performance and longevity. Here are some tips for maintaining and caring for the QSFP-4SFP10G-CU5M= cable:

  • Avoid physical damage: The cable should be handled with care to avoid physical damage. Any bends, twists, or kinks in the cable can cause signal distortion, attenuation, or even cable breakage.
  • Clean connectors: The connectors on both ends of the cable should be kept clean to ensure proper connectivity. Use a lint-free cloth or cleaning swab with an appropriate cleaning solution to clean the connectors.
  • Avoid extreme temperatures: The cable should be kept away from extreme temperatures, both high and low, to avoid damage to the cable and connectors. Extreme temperatures can cause thermal expansion and contraction, which can damage the cable.
  • Proper storage: When the cable is not in use, it should be stored properly in a cool and dry place to avoid any damage from moisture or dust.
  • Avoid excessive tension: Excessive tension or pulling force on the cable can cause damage to the cable, connectors, or both. Avoid any excessive tension or pulling force on the cable.
  • Regular inspection: The cable should be inspected regularly for any physical damage or signs of wear and tear. Any damaged cables should be replaced immediately.

Troubleshooting Common Issues

The QSFP-4SFP10G-CU5M= Cisco 5M SFP+ copper Direct-Attach Breakout Cable is a high-speed copper cable that connects network devices with 40G QSFP+ ports to devices with 10G SFP+ ports. Despite being a high-quality cable, there may be some common issues that you could encounter while using it. Here are some of the troubleshooting tips for those common issues:

  • Cable Length Limitation: The maximum length for QSFP-4SFP10G-CU5M= Cisco 5M SFP+ copper Direct-Attach Breakout Cable is 5 meters. If you require a longer cable length, you may need to use fiber optic cables. To resolve this issue, make sure you are using the correct cable length.
  • Connectivity Issue: Check if the cable is properly connected to the device ports. Make sure that the cable is inserted correctly and securely into the ports.
  • Compatibility Issue: Check if the devices that are being connected using the QSFP-4SFP10G-CU5M= Cisco 5M SFP+ copper Direct-Attach Breakout Cable are compatible. Some devices may not work together, causing connectivity issues.
  • Power Issues: Check if the devices are receiving enough power to function properly. If the devices are not receiving sufficient power, they may not work correctly.
  • Quality Issues: Check for any physical damages to the cable such as frayed or broken wires. If you notice any damage, replace the cable immediately.
  • Distance Limitation: QSFP-4SFP10G-CU5M= Cisco 5M SFP+ copper Direct-Attach Breakout Cable is only designed for short-distance connectivity. Check if the devices are located within the recommended distance limits.
  • Signal Interference: Check if there are any devices or cables that may be interfering with the signal. Electrical devices such as motors or transformers may create electromagnetic interference that can affect the cable's signal.
