Introduction to the Optical Cable
The Cisco QSFP-H40G-AOC25M= is a 25-meter long direct attach copper cable that uses QSFP+ connectors on both ends. It is designed to provide a high-speed, reliable, and cost-effective solution for connecting switches, servers, and storage devices within a data center environment.
The QSFP-H40G-AOC25M= cable supports data transfer rates of up to 40Gbps and is compliant with the 40GBASE-CR4, 40GBASE-SR4, and 40GBASE-SR-BiDi standards. It is pre-configured with Cisco compatible QSFP+ transceivers and supports hot-swappable installation, making it easy to install and remove as needed.
The cable features active electrical components that help to amplify the signal and extend the reach of the connection, ensuring reliable performance over the full 25-meter length of the cable. The use of copper cabling also provides lower latency and power consumption compared to optical fiber cables, making it an ideal choice for short-distance data center interconnects.
The QSFP-H40G-AOC25M= cable is also fully compatible with Cisco switches and other networking equipment, ensuring seamless integration and hassle-free deployment. It comes with a limited lifetime warranty from Cisco, providing additional peace of mind and assurance of its quality and reliability.
Cable Length and Distance Support
The Cisco QSFP-H40G-AOC25M= is a 25-meter long, 40GBASE QSFP+ to QSFP+ direct attach cable (DAC) designed for high-speed data transmission between switches, routers, servers, and other network devices.
The cable supports a maximum data transfer rate of 40 Gbps and is compliant with the IEEE 802.3ba standard. It uses four parallel, multi-mode fibers with a wavelength of 850 nm to transmit data. The cable also incorporates active optical components that convert electrical signals to optical signals for transmission over longer distances than passive copper cables.
In terms of physical dimensions, the Cisco QSFP-H40G-AOC25M= cable has a QSFP+ form factor with a length of 25 meters (82 feet). The QSFP+ connectors at each end of the cable are designed to support hot-swapping, which allows for the cable to be plugged and unplugged without shutting down the connected devices.
High-Speed Data Transmission
The Cisco QSFP-H40G-AOC25M= direct attach cable is designed for high-speed data transmission of up to 40Gbps over a distance of 25 meters. It uses QSFP+ connectors on both ends of the cable, which support a wide range of data center applications and networking equipment.
The cable is compliant with the 40GBASE-CR4, 40GBASE-SR4, and 40GBASE-SR-BiDi standards, which ensure reliable performance and compatibility with a variety of networking devices. The use of copper cabling also provides lower latency and power consumption compared to optical fiber cables, making it an ideal choice for short-distance data center interconnects.
The QSFP-H40G-AOC25M= cable features active electrical components that help to amplify the signal and extend the reach of the connection, ensuring reliable performance over the full 25-meter length of the cable. The active components also enable the cable to support a longer distance compared to passive cables.
In addition, the cable supports hot-swappable installation, making it easy to install and remove as needed without disrupting the rest of the network. It is also fully compatible with Cisco switches and other networking equipment, ensuring seamless integration and hassle-free deployment.

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!
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!
