Features and Specifications of Passive Copper Cable
The Cisco QSFP-100G-CU5M= is a 16.40 feet (5 meter) QSFP (Quad Small Form-Factor Pluggable) passive copper cable that is designed to provide reliable, high-speed connectivity between compatible Cisco networking devices.
Here are some of the key features and specifications of the Cisco QSFP-100G-CU5M= cable:
- QSFP form factor: The QSFP-100G-CU5M= cable is designed to connect QSFP ports on Cisco networking devices, including switches and routers.
- Passive copper technology: The cable uses passive copper technology, which means that it does not require any power source or signal boosting. This can help reduce costs and complexity compared to active optical cables.
- High-speed connectivity: The Cisco QSFP-100G-CU5M= cable is capable of delivering data transfer speeds of up to 100 Gbps, making it suitable for high-speed networking applications such as data center interconnects, high-performance computing, and cloud computing.

Types of Connectors Used in 5 Meter QSFP Copper Cables
The Cisco QSFP-100G-CU5M= is a high-speed copper cable that is designed to connect switches, servers, routers, and other network devices. It uses Quad Small Form-factor Pluggable (QSFP) connectors, which are a type of hot-pluggable transceiver module that can transmit and receive data over optical fiber or copper cable.
The QSFP-100G-CU5M= cable uses copper conductors to transmit data over a distance of up to 5 meters (16.40 feet) at a speed of 100 gigabits per second (Gbps). It has four lanes of data transmission, with each lane capable of transmitting data at a rate of up to 25 Gbps.
The connectors used in the QSFP-100G-CU5M= cable are QSFP connectors, which are 38-pin connectors that are used to attach the cable to a network device. The pins are arranged in a staggered pattern to ensure that the cable is properly aligned when it is inserted into the device.
There are four types of QSFP connectors that are commonly used:
- QSFP-DD: This is the newest type of QSFP connector and it is used in high-speed data centers. It has 76 pins and is capable of transmitting data at a rate of up to 400 Gbps.
- QSFP28: This connector is used for 100 Gbps and 40 Gbps Ethernet applications. It has 38 pins and is capable of transmitting data at a rate of up to 28 Gbps per lane.
- QSFP+: This connector is used for 40 Gbps and 10 Gbps Ethernet applications. It has 38 pins and is capable of transmitting data at a rate of up to 10 Gbps per lane.
- QSFP: This connector is used for 40 Gbps and 4x10 Gbps Ethernet applications. It has 38 pins and is capable of transmitting data at a rate of up to 10 Gbps per lane.
Maintenance and Troubleshooting
The Cisco QSFP-100G-CU5M= is a high-speed passive copper cable designed to provide 100Gbps connectivity between Cisco switches, routers, and other network equipment. It is a 5-meter long cable that uses QSFP (Quad Small Form-factor Pluggable) connectors on both ends to establish a reliable and fast data link.
Maintenance: To ensure optimal performance and longevity of the Cisco QSFP-100G-CU5M= cable, it's essential to follow these maintenance guidelines:
- Avoid excessive bending or pulling of the cable.
- Keep the cable clean and free of dust and debris.
- Store the cable in a dry and cool place when not in use.
- Inspect the cable periodically for any signs of damage or wear and tear.
- Avoid exposing the cable to extreme temperatures, humidity, or direct sunlight.
Troubleshooting: If you experience any issues with the Cisco QSFP-100G-CU5M= cable, you can try these troubleshooting steps:
- Check the cable connections on both ends to ensure they are secure and properly seated.
- Verify that the cable is compatible with your Cisco equipment and that it meets the required specifications.
- Inspect the cable for any signs of damage or breakage.
- Try swapping the cable with a known good cable to rule out any issues with the network equipment or the cable itself.
- Use diagnostic tools provided by Cisco to identify any errors or connectivity issues.

About New Bulk Pack 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. If you are not sure, consult with the sales representatives for any help. At ALLHDD, we have a technical team to help you solve any mystery in cable selection.
