Description
High-Performance Computing of Direct Attach Cable
Cisco QSFP-H40G-AOC25M is a high-performance computing cable that provides a 40Gbps data transfer rate over a distance of 25 meters. It uses the QSFP+ (Quad Small Form-factor Pluggable Plus) interface on both ends of the cable, allowing for direct attach connections between two switches or servers.
Here are some key features of Cisco QSFP-H40G-AOC25M:
- QSFP+ to QSFP+ direct attach cable: The cable has QSFP+ connectors on both ends, which can be directly plugged into QSFP+ ports on switches or servers.
- Active Optical Cable (AOC) technology: The cable uses AOC technology to transmit data signals over fiber optic cables. AOC cables consist of optical fibers and optical transceivers, which convert electrical signals into optical signals and vice versa.
- High-speed data transfer: The cable provides a data transfer rate of 40Gbps, which is ideal for high-performance computing applications such as data center interconnects, high-performance computing clusters, and cloud computing.
- Long-distance transmission: The cable can transmit data over a distance of up to 25 meters, making it suitable for use in large data centers and server rooms.
- Low latency: The cable provides low latency, which is critical for real-time applications such as high-frequency trading and online gaming.
- Hot-swappable: The cable is hot-swappable, which means it can be replaced or installed without shutting down the devices connected to it.
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.
