The Cisco QDD-400-CU2M is a 2-meter long QSFP-DD to QSFP-DD passive copper cable designed for high-performance computing applications. This cable is specifically designed to connect switches, servers, and other network devices that require high-speed data transfer rates.
The QSFP-DD connector is a small form-factor pluggable (SFP) interface that supports data transfer rates of up to 400 Gbps. It consists of 8 pairs of differential channels that can transmit data at a rate of 50 Gbps per channel. The QSFP-DD connector is backwards compatible with QSFP and QSFP+ interfaces, which means that it can be used with existing QSFP devices.
The Cisco QDD-400-CU2M cable is a passive copper cable, which means that it does not require any active components such as signal repeaters or amplifiers to transmit data. This makes the cable more cost-effective than active copper cables or optical cables, which require expensive active components.
The QDD-400-CU2M cable is designed to meet the requirements of high-performance computing applications such as data center networking, cloud computing, and high-performance computing clusters. It is capable of transmitting data at a rate of up to 400 Gbps over a distance of 2 meters. The cable is also designed to support the latest Ethernet standards such as 100GbE, 200GbE, and 400GbE.
The QDD-400-CU2M cable is designed to be highly reliable and durable. It is made from high-quality materials and is tested to meet or exceed industry standards for quality and performance. The cable also features an EMI shield to reduce electromagnetic interference and improve signal integrity.
Aerospace and Defense of Passive Copper Cable
The Cisco QDD-400-CU2M is a 2-meter QSFP-DD to QSFP-DD passive copper cable designed for use in high-speed data center and networking applications. QSFP-DD stands for Quad Small Form-factor Pluggable Double Density, which is a new standard for high-speed networking that supports data rates up to 400 Gbps.
The QDD-400-CU2M cable is part of Cisco's Aerospace and Defense portfolio, which provides solutions for mission-critical applications in the aerospace and defense industry. These solutions are designed to meet the strict requirements for reliability, durability, and performance in harsh environments such as military aircraft, spacecraft, and ground-based defense systems.
The QDD-400-CU2M cable is specifically designed to provide high-speed connectivity between QSFP-DD-enabled networking devices, such as switches, routers, and servers. The cable features a QSFP-DD connector on both ends, allowing for easy installation and compatibility with other QSFP-DD-enabled devices.
The cable is also designed with passive copper technology, which provides a cost-effective and reliable solution for high-speed data transmission over short distances. Passive copper technology uses copper wires to transmit data without the need for active components such as repeaters or amplifiers, making it a simpler and more cost-effective solution for short-range connectivity.
In terms of performance, the QDD-400-CU2M cable supports data rates up to 400 Gbps and is compliant with the QSFP-DD MSA (Multi-Source Agreement) standard. The cable also features low insertion loss and crosstalk, ensuring reliable data transmission over the entire length of the cable.
Quality Control Measures of 2 Meter Copper Cable
Cisco QDD-400-CU2M is a 2-meter long QSFP-DD to QSFP-DD passive copper cable designed to connect different networking equipment such as switches, routers, and servers. To ensure the quality of the cable and its performance, Cisco employs several quality control measures during the manufacturing and testing process.
Here are some of the quality control measures taken by Cisco for the QDD-400-CU2M cable:
- Manufacturing processes: Cisco follows strict manufacturing processes to ensure that the cable is built to the highest quality standards. This includes using high-quality materials, such as oxygen-free copper conductors, which are designed to reduce signal loss and interference.
- Testing: Cisco performs extensive testing on every cable to ensure that it meets the industry standards for performance and reliability. This includes tests for signal integrity, noise reduction, and thermal performance.
- Certification: The QDD-400-CU2M cable is certified by the Fibre Channel Industry Association (FCIA) and meets the requirements of the InfiniBand Trade Association (IBTA). These certifications ensure that the cable is compatible with a wide range of networking equipment and meets the highest standards for quality and performance.
- Packaging: Cisco ensures that the cable is packaged and shipped in a way that prevents any damage during transit. The cable is packed in a protective box to prevent bending or kinking of the cable.
- Warranty: The QDD-400-CU2M cable comes with a limited lifetime warranty from Cisco. This warranty ensures that the cable will be free from defects in material and workmanship and will perform as expected.
