Description
Features and Specifications of 2.5 Meter Copper Cable
The Cisco QDD-400-CU2.5M QSFP Passive 2.5M Copper Cable is a high-speed networking cable that is designed to connect network switches, routers, and other networking devices. It is a direct attach copper (DAC) cable that supports 40 Gigabit Ethernet (GbE) data transfer speeds, making it ideal for high-bandwidth applications such as data centers, server farms, and cloud computing environments.
Some of the key features and specifications of the Cisco QDD-400-CU2.5M QSFP Passive 2.5M Copper Cable include:
- Cable length: The cable is 2.5 meters (8.2 feet) long, which is suitable for connecting devices in close proximity.
- Connector type: The cable features QSFP connectors on both ends, which are compatible with QSFP ports on Cisco networking devices and other brands of networking equipment that support QSFP interfaces.
- Data transfer speed: The cable supports data transfer speeds of up to 40 GbE, which is sufficient for high-bandwidth applications.
- Cable type: The cable is a passive copper cable, which means that it does not require any power to operate.
- Temperature range: The cable is designed to operate in a wide temperature range, from 0°C to 70°C, which makes it suitable for use in a variety of environments.
- Compatibility: The cable is compatible with a wide range of Cisco networking devices, including Cisco Nexus switches, Cisco Catalyst switches, and Cisco ASR routers.
Working Principle of QSFP Cable
The Cisco QDD-400-CU2.5M QSFP Passive 2.5M Copper Cable is a high-speed cable designed to provide reliable connectivity between switches, routers, servers, and storage devices. It is designed to work with QSFP ports, which are commonly found in data centers and high-performance computing environments.
The cable is made up of four high-speed copper pairs, each capable of carrying data at speeds of up to 10 Gbps. These copper pairs are twisted together to minimize crosstalk and interference, which helps to ensure reliable data transmission.
The working principle of the Cisco QDD-400-CU2.5M QSFP Passive 2.5M Copper Cable is relatively simple. When connected to a QSFP port on a switch or other networking device, the cable establishes a physical link between the two devices. Data is then transmitted through the cable using a variety of protocols, depending on the specific networking application.
One key advantage of the Cisco QDD-400-CU2.5M QSFP Passive 2.5M Copper Cable is its passive design. Unlike active cables, which require power to transmit data, passive cables use no power and simply rely on the physical properties of the cable itself to transmit data. This makes the cable simpler and less expensive to manufacture, while also reducing the risk of failure due to power issues.
Benefits of Passive Copper Cable
The Cisco QDD-400-CU2.5M QSFP Passive 2.5M Copper Cable is a high-speed networking cable that provides several benefits to users. Here are some of the benefits of using this cable:
- High speed connectivity: The Cisco QDD-400-CU2.5M cable provides a high-speed connectivity solution with a data transfer rate of up to 40 Gbps. This makes it an ideal cable for high-bandwidth applications such as data centers, cloud computing, and video streaming.
- Passive design: This cable has a passive design, which means that it does not require any power source or active components. This makes it easy to install and use, and also reduces the overall power consumption of the system.
- Copper construction: The cable is made of copper, which is a highly conductive material that provides superior signal quality and reduces signal loss. Copper cables are also more affordable than optical cables, making them a cost-effective solution for high-speed connectivity.
- QSFP+ form factor: The cable is designed to support the QSFP+ form factor, which is a compact and versatile interface that can support multiple data rates and protocols. This makes the cable compatible with a wide range of devices and networking equipment.
- Length: The cable is 2.5 meters in length, which provides sufficient distance for connecting devices in close proximity to each other. Longer cables can be used with the help of compatible extender modules.
