Design and Construction of Network Cable
The QSFP-H40G-ACU7M= is a 7-meter long Cisco QSFP+ Direct Attach Copper (DAC) network cable designed for high-speed data transmission in data center environments. It is specifically designed for use with Cisco networking equipment, such as switches and routers, that support QSFP+ ports.
The cable is constructed using high-quality materials and advanced manufacturing techniques to ensure reliable and high-performance data transmission. The cable features four high-speed copper channels, each capable of transmitting data at speeds of up to 10 Gbps, resulting in a total bandwidth of up to 40 Gbps.
The QSFP-H40G-ACU7M= cable features quad small form-factor pluggable plus (QSFP+) connectors on both ends, which are designed to connect to QSFP+ ports on networking equipment. The connectors are made of high-quality materials and are designed to provide a secure and reliable connection.
The cable is designed to be hot-swappable, meaning that it can be installed or removed from a networking device without powering down the device or disrupting the network. This feature makes it easy to add or remove devices from the network without causing any downtime or interruption to network services.
The QSFP-H40G-ACU7M= cable is also designed to be low-power, which helps to reduce energy consumption and operating costs. The cable features a high-quality copper conductor, which provides excellent signal quality and reduces the risk of data loss or signal degradation.
Key Features of 7 Meter DAC Network Cable
The QSFP-H40G-ACU7M= Cisco 7M QSFP+ DAC Network Cable is a high-speed direct-attach copper cable that connects devices with QSFP+ interfaces. Here are some key features of this cable:
- Length: The cable is 7 meters long, making it suitable for connecting devices that are relatively far apart.
- Compatibility: The QSFP-H40G-ACU7M= cable is designed to work with Cisco networking equipment that has QSFP+ interfaces. It is compatible with a wide range of Cisco switches, routers, and other network devices.
- High-speed data transfer: The cable supports data transfer rates of up to 40Gbps, making it ideal for high-bandwidth applications such as data center networking, storage networking, and high-performance computing.
- Direct-attach copper (DAC) technology: The QSFP-H40G-ACU7M= cable uses DAC technology, which provides a cost-effective, low-power, and low-latency solution for interconnecting devices over short distances.
- Passive cable: The cable is a passive cable, which means it does not require any power or signal conditioning. This makes it easy to install and use.
- Copper conductors: The cable has four copper conductors, one for each of the four channels. Copper conductors are preferred for short-distance connections because they offer low resistance and high conductivity, which ensures reliable data transfer.
- QSFP+ form factor: The cable uses the QSFP+ form factor, which is a compact, hot-pluggable interface that supports four independent data channels. This form factor is widely used in data centers and high-performance computing environments.
Quality Control Measures
The QSFP-H40G-ACU7M= Cisco 7M QSFP+ DAC Network Cable is a high-speed data transmission cable that is designed to provide reliable connectivity between network devices. To ensure that the cable performs optimally and meets the desired standards, several quality control measures are put in place during its production.
- Material selection: The cable is made of high-quality materials that are carefully selected to ensure optimal performance. This includes high-quality copper wires and connectors that are designed to withstand high data transfer rates and reduce signal interference.
- Performance testing: The cable is subjected to rigorous performance testing to ensure that it meets the desired standards for data transmission. This includes testing the cable for its data transfer rate, signal strength, and signal-to-noise ratio.
- Quality assurance: The cable is subjected to strict quality assurance processes to ensure that it is free from defects and meets the desired standards for durability and reliability.
- Manufacturing processes: The cable is manufactured using advanced processes that ensure consistent quality and reliability. This includes using automated machinery and processes that reduce the likelihood of human error and ensure that each cable is made to the same exacting standards.
- Packaging and shipping: The cable is carefully packaged to ensure that it arrives at its destination in optimal condition. This includes using protective packaging materials that prevent damage during shipping and storage.

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!
