The QSFP-H40G-CU4M is a Cisco 4 Meter Passive Direct Attach Copper (DAC) Network Cable that is used to connect network devices such as switches, routers, and servers. Here are the features and benefits of this cable:
Features:
- Length: The cable is 4 meters (13.12 feet) in length, which provides flexibility in connecting devices that are located at a distance from each other.
- Connector types: The QSFP-H40G-CU4M cable has Quad Small Form-factor Pluggable (QSFP+) connectors on both ends, which are designed to fit into QSFP+ ports on network devices.
- Data transfer rate: The cable supports data transfer rates up to 40 Gbps, which makes it suitable for high-speed data transfer applications.
- Passive design: The cable is passive, which means it does not require power to operate.
- Copper construction: The cable is made of copper, which provides a reliable and cost-effective solution for connecting devices in a network.
Benefits:
- Easy to install: The QSFP-H40G-CU4M cable is easy to install, with no additional hardware or software required.
- Cost-effective: The cable is a cost-effective solution for connecting devices in a network, as it is less expensive than other high-speed data transfer cables.
- High performance: The cable supports high-speed data transfer rates up to 40 Gbps, which makes it ideal for applications that require high bandwidth.
- Reliable: The copper construction of the cable provides a reliable connection between devices in a network, with minimal signal loss or interference.
- Compatibility: The QSFP-H40G-CU4M cable is compatible with a range of Cisco devices, including switches, routers, and servers, which makes it a versatile solution for different network configurations.
Installing and configuring the QSFP-H40G-CU4M Cisco 4 Meter Passive DAC Network Cable is relatively straightforward. Here are the general steps for installing and configuring this cable:
- Power off the devices: Before connecting the cable, power off the network devices that you want to connect with the QSFP-H40G-CU4M cable.
- Identify the ports: Identify the QSFP+ ports on the devices that you want to connect. These ports are typically labeled with a "QSFP+" or "40G" marking.
- Connect the cable: Connect one end of the QSFP-H40G-CU4M cable to the QSFP+ port on one device and the other end to the QSFP+ port on the other device. Ensure that the connectors are securely fastened.
- Power on the devices: Once the cable is connected, power on the network devices.
- Verify the connection: Once the devices are powered on, verify that they have established a link over the cable. You can do this by checking the interface status or using network diagnostic tools.
- Configure the devices: If necessary, configure the network devices to use the QSFP-H40G-CU4M cable. The configuration steps may vary depending on the devices and the specific network configuration, so consult the manufacturer's documentation for guidance.
There are several differences between the QSFP-H40G-CU4M Cisco 4 Meter Passive DAC Network Cable and other types of network cables. Here are some of the main differences:
- Cable type: The QSFP-H40G-CU4M cable is a copper-based direct attach cable (DAC), whereas other types of network cables may use different types of conductors, such as optical fibers or twisted pair copper.
- Speed: The QSFP-H40G-CU4M cable supports data transfer rates of up to 40 Gbps, which is much faster than many other types of network cables. For example, a Cat 6 Ethernet cable typically supports data transfer rates of up to 10 Gbps.
- Length: The QSFP-H40G-CU4M cable is 4 meters in length, whereas other types of network cables may be shorter or longer. The length of a cable can affect its performance, as longer cables may experience more signal degradation.
- Connector type: The QSFP-H40G-CU4M cable has QSFP+ connectors on both ends, which are designed to fit into QSFP+ ports on network devices. Other types of network cables may have different types of connectors, such as RJ-45 connectors for Ethernet cables.
- Power requirements: The QSFP-H40G-CU4M cable is a passive DAC, meaning that it does not require external power to transmit data. Other types of network cables, such as optical fibers, may require external power to transmit data.
