Distance Capabilities & Transmission Speeds

The Cisco QSFP-H40G-CU2M= 2M QSFP+ Twinaxial Passive Direct-attach Copper Cable supports a maximum data transfer rate of 40 Gbps. This cable is designed to be used in high-speed networking applications, such as data centers and cloud computing environments.

The QSFP-H40G-CU2M cable is a passive copper cable, which means it does not require any additional power or cooling. The cable is designed to be used with QSFP+ ports, which are commonly found on networking devices such as switches, routers, and servers.

The maximum distance supported by the QSFP-H40G-CU2M cable depends on a number of factors, including the type of networking device, the specific network topology, and the environmental conditions. In general, passive copper cables such as the QSFP-H40G-CU2M are designed for use in short-distance applications, typically within a rack or between adjacent racks.

Quality and Reliability

The QSFP-H40G-CU2M= Cisco 2M QSFP+ Twinaxial Passive Direct-attach Copper Cable is a high-quality and reliable solution for high-speed data center applications that require low latency and high bandwidth. Here are some of the key factors that contribute to its quality and reliability:

  • High-Quality Materials: The QSFP-H40G-CU2M= cable is built with high-quality materials, including copper wire and QSFP connectors, which are designed to withstand the rigors of data center environments.
  • Rigorous Testing: The cable is rigorously tested by Cisco to ensure that it meets or exceeds industry standards for performance and reliability.
  • Passive Copper Cable: The QSFP-H40G-CU2M= is a passive copper cable, which means that it does not require any external power source or equipment for operation, making it more reliable and less prone to failure than active cables.
  • Low Latency: The cable has low latency, which is essential for high-speed data center applications that require real-time data processing and fast response times.
  • High Bandwidth: The cable supports data transfer rates of up to 40 Gbps, which provides high bandwidth and throughput for data center applications.
  • Compatibility: The QSFP-H40G-CU2M= cable is compatible with Cisco networking equipment that supports QSFP interfaces, which makes it easy to integrate into existing data center infrastructures.
  • Warranty: The cable comes with a limited lifetime warranty from Cisco, which provides assurance that it is a high-quality and reliable solution for data center applications.

Installation and Configuration

The installation of the Cisco QSFP-H40G-CU2M= 2M QSFP+ Twinaxial Passive Direct-attach Copper Cable is straightforward and can be done by following these steps:

  • Ensure that the device is turned off and disconnected from the power source before installing the cable.
  • Align the QSFP+ connectors on the device and the cable.
  • Insert the QSFP+ connectors into their respective ports and gently push until they click into place.
  • Secure the cable by tightening the screws on the connector, if applicable.

Once the cable is installed, it should be configured according to the specific requirements of the network topology and the connected devices. Configuration steps may vary depending on the specific devices being used, but generally involve configuring the devices to recognize and utilize the QSFP-H40G-CU2M cable as a valid connection.

It is important to ensure that all connected devices are configured with the appropriate settings to support the maximum transmission speed of the QSFP-H40G-CU2M cable. This may include configuring settings such as link speed, duplex mode, and flow control settings.

In addition, it is important to follow best practices for cable management, including using cable trays or other cable management systems to ensure proper cable routing, and using cable strain relief measures to prevent damage to the cable or connectors.

Regular cable inspections can also help to identify and address any physical damage or wear that may affect cable performance. Overall, proper installation and configuration of the QSFP-H40G-CU2M cable can help to ensure optimal performance and reliability of the network infrastructure.

Cables - Direct Attach Cable

Direct Attach Cable, also known as the DAC cable, connects the equipment and peripherals in a data network. All the active networking equipment, including the data storage devices, switches, routers, servers, and more, will be connected and synched using the DAC cables. As far as the usage is concerned, these direct attached copper cables are getting fame in the data storage centers and the industry sector and server rooms: the reason being the cost-effective, efficient, and easier way to form the connection.

Direct Attach Copper Cables Are Terminated with Modules:

DAC cables are terminated from the manufacturer with the modules, which can easily connect the active peripheral equipment and secure an electrical connection. These modules are factory terminated and cannot be removed from the DAC cables afterward. Hence these wires possess a fixed length.

There are plenty of types and models available for the direct attach cables, including the direct, breakout, active and passive. As mentioned in the name, the direct cable can form a direct stable connection among the two peripherals, while breakout can connect one port with the four others. On the other hand, an active DAC cable will transmit signals to a little longer distance than the passive ones.

We, at ALLHDD, have got you all the range DAC cables for you to shop from! Choose from the following sub-categories: 0.5 Meter, 1 Meter, 16.4 Feet, 2 Meter, 4xC-13 Attached, 5 Meters, SFP+, 0.65 Meter, 10 Feet, 10 Meters, and 3 Meter.

DAC cables can follow longer paths:

Many of you might be wondering if the direct attach cable can transmit the data up to 10 meters or more! Yes, these cables can transfer the data to a more extended range depending on the data rate. The data rate is inversely proportional to the transmit range- the more the data rate, the less will be the range!

Direct Attach Data Cables are cost-effective!

DAC cables are more cost-effective as compared to the other ones. Using the two optical transceivers and fiber cable will not generate similar results as these DAC cables would!

Immense Reliability:

Not only are these cost-effective and can cover long range but are reliable as well! As already mentioned, the DAC cables are factory terminated with a module that plugs into the networking equipment and generates a physical connection. Apart from the secure connection, the 26 to 28 AWG Copper material makes them rugged. Therefore, surviving through the damage and cracks, DAC cables are a way to connect peripherals swiftly. You can choose from the following options 7 Meter, ProCurve, 0.65M, 1.2 Meter, 20 Meter and 30 Meter and also claim a 2.5% discount!
