Cable Length and Distance Support
The Cisco QSFP-H40G-CU0-5M= 0.5m 40GbE QSFP Twinaxial Passive Copper Cable is a high-speed copper cable designed for use in data centers and other high-performance computing environments. This cable has a length of 0.5 meters, which makes it ideal for short-range connections.
The QSFP-H40G-CU0-5M= supports data transfer rates of up to 40 Gigabits per second (Gbps) using four 10 Gbps channels. This cable is compatible with a wide range of networking equipment, including Cisco switches, routers, and servers.
One advantage of using the QSFP-H40G-CU0-5M= cable is that it is a cost-effective solution for short-range data transmission compared to optical cables. Copper cables are generally less expensive than optical cables and do not require special handling or installation considerations.
Regulatory and Compliance Information
The Cisco QSFP-H40G-CU0-5M= 0.5m 40GbE QSFP Twinaxial Passive Copper Cable complies with several regulatory and compliance standards, including:
- RoHS: The cable is compliant with the European Union's Restriction of Hazardous Substances (RoHS) directive, which restricts the use of certain hazardous substances in electronic and electrical equipment.
- REACH: The cable is also compliant with the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation, which aims to protect human health and the environment from the risks posed by chemicals.
- TAA: The cable complies with the Trade Agreements Act (TAA), which requires that products purchased by the U.S. government are made in the United States or in designated countries that have a free trade agreement with the United States.
- FCC: The cable complies with the regulations set forth by the Federal Communications Commission (FCC) in the United States.
- CE: The cable also complies with the CE Marking requirements, which indicate that the product meets certain safety, health, and environmental protection standards for products sold within the European Economic Area.
In addition to these standards, the Cisco QSFP-H40G-CU0-5M= cable may also comply with other industry-specific regulations or standards, depending on its intended use and application.
Data Transfer Rates
The Cisco QSFP-H40G-CU0-5M= 0.5m 40GbE QSFP Twinaxial Passive Copper Cable is a high-speed copper cable designed for use in data centers and other high-performance computing environments. This cable supports data transfer rates of up to 40 Gigabits per second (Gbps) using four 10 Gbps channels.
The QSFP-H40G-CU0-5M= cable is designed to provide reliable and high-speed connectivity between networking equipment, including switches, routers, and servers. This cable uses a twinaxial copper design, which provides high-speed data transfer with low latency.
Compared to optical cables, copper cables like the QSFP-H40G-CU0-5M= are generally less expensive and do not require special handling or installation considerations. However, copper cables have a shorter maximum transmission distance compared to optical cables, which may limit their use in larger data center environments.

About Refurbished Products
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!
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!
