Performance and Reliability of QSFP Passive Cable
The Cisco QSFP-100G-CU5M is a 16.40 feet (5 meters) QSFP+ passive copper cable that is designed to provide high-speed data connectivity between network devices that are equipped with QSFP+ ports. The cable supports a data transfer rate of up to 100 Gbps, making it suitable for use in high-performance computing environments such as data centers.
In terms of performance, the Cisco QSFP-100G-CU5M cable is designed to meet industry standards for high-speed data transmission. The cable uses a passive copper design, which means that it does not require any external power source to transmit data. This makes it an energy-efficient solution that is ideal for use in environments where power consumption is a concern.
The reliability of the Cisco QSFP-100G-CU5M cable is also an important consideration. The cable is designed to be durable and long-lasting, with a robust construction that can withstand repeated plugging and unplugging. Additionally, the cable is shielded to prevent electromagnetic interference (EMI) and crosstalk, which can degrade signal quality and cause data transmission errors.
Installing & Maintaining Tips and Tricks
The Cisco QSFP-100G-CU5M is a 16.40 feet QSFP (Quad Small Form-factor Pluggable) passive copper cable that provides a cost-effective way to connect devices in a data center or enterprise network. Here are some tips and tricks for installing and maintaining this cable:
- Verify Compatibility: Before installing the Cisco QSFP-100G-CU5M cable, ensure that it is compatible with the devices you want to connect. Check the datasheet or manual of your devices to verify their QSFP compatibility and cable requirements.
- Proper Handling: When handling the cable, avoid pulling or twisting it too much. Do not bend the cable beyond its minimum bend radius, which is usually specified in the datasheet or manual. Also, avoid exposing the cable to extreme temperatures, moisture, or dust.
- Proper Installation: The Cisco QSFP-100G-CU5M cable can be plugged directly into QSFP ports on compatible devices. Ensure that the cable is properly seated and secured to prevent accidental disconnections. Avoid installing the cable near sources of electromagnetic interference, such as power cables or motors.
- Cable Management: Proper cable management is essential for maintaining a clean and organized data center or network. Use cable ties or Velcro straps to bundle and organize cables. Avoid placing cables near heat sources or sharp objects that may damage them.
- Regular Inspection: Regularly inspect the cable for any signs of wear, damage, or loose connections. If you notice any problems, replace the cable immediately to prevent network downtime or data loss.
- Firmware Updates: Ensure that your devices have the latest firmware updates installed, as this can improve compatibility and performance with the Cisco QSFP-100G-CU5M cable.
- Cleaning: Periodically clean the cable connectors and ports using a lint-free cloth and isopropyl alcohol to remove any dirt or debris. Avoid using abrasive cleaners or materials that may damage the cable or ports.
Troubleshooting Common Issues
The Cisco QSFP-100G-CU5M is a 16.40 feet QSFP passive copper cable used for high-speed data transmission in data centers and enterprise networks. Like any other networking equipment, it can encounter issues that may require troubleshooting. Here are some common issues that may arise with the Cisco QSFP-100G-CU5M cable and how to troubleshoot them:
- Poor or no connectivity: If the cable is not providing a stable connection or no connectivity at all, the first step is to check the physical connections. Make sure the connectors are properly seated in the ports and the cable is securely plugged in. If the issue persists, try replacing the cable with a new one.
- Signal loss: Signal loss can be caused by several factors, including cable length, electromagnetic interference (EMI), and signal attenuation. To troubleshoot signal loss, first, check the cable length and ensure it is within the recommended range. Then, try relocating the cable away from any potential sources of EMI, such as power cables or electrical equipment. If the issue persists, it may be necessary to use a signal booster or a signal regenerator to amplify the signal.
- Compatibility issues: The Cisco QSFP-100G-CU5M cable may not be compatible with all networking equipment. Before purchasing the cable, check the compatibility matrix provided by Cisco or consult with a networking expert. If the cable is not compatible, it may cause connectivity issues or even damage the equipment.
- Bent or damaged connectors: Bent or damaged connectors can cause poor connectivity or even break the cable altogether. If the connectors are bent or damaged, replace the cable with a new one.
- Length limitations: The Cisco QSFP-100G-CU5M cable has a maximum length of 16.40 feet. If the cable is too short or too long, it may cause signal loss or other connectivity issues. Ensure that the cable length is within the recommended range.

About Refurbished Products
Cables - Copper Cable
Coper cables still remain the most popular option in high voltage and low voltage applications such as networking. Despite the disadvantages, such as electromagnetic interference, copper still offers a cost-effective solution for many applications.
How does Copper Cable Transmit Data?
It is a simple process that starts by energizing one side of a copper wire to set electrons in it in motion. The electrons travel to the other end of the wire with the signal information. Since movement is involved, you can expect the electrons to lose their energy and eventually stop moving if the cable is very long. The loss of electron energy leads to a reduction in signal strength. When the electrons stop moving before reaching the other end of the copper wire, a total signal loss occurs. In long-distance data transmission, boosters are placed at an appropriate location to re-energize the electrons. That is usually not a problem of concern when wiring your server because of the short distance involved.
Does Length of Copper Cables Matter?
Yes, it does. As already mentioned, there is a degradation of signals as they move through the copper conductor due to losses. Copper wires have an internal resistance that will oppose the movement of current through them. Data moves through these copper cables as a stream of or pulses of current. The longer the wire, the higher the resistance and more likely signal strength deterioration. Think of it as walking uphill. The further you go, the more tired you become, and you may eventually stop moving.
When you are shopping for copper cables, just make sure you get an appropriate wire length for the application. Do not use a 10-meter cable where you can use a 5-meter cable. You make your system more efficient by using the best cable for the application.
Copper Cables for Every Application
You might have been made to believe that all copper cables are the same. That is not true. Manufacturers of these cables do so with specific applications in mind. A different approach is followed for applications where data rate and bandwidth are a priority. That is why you will find InfiniBand copper cables intended for such applications. Also, the connectors at the end of the copper wires show the intended use. You will find a big difference in the connectors used by IBM's RIO-2 copper cable and HP's X240 direct attach cable.When you are shopping for a copper cable, know what you intend to use it for.
