High-Speed Networking of Copper Cable
The Cisco QDD-400-CU3M= is a high-speed networking cable designed for use in data centers and other high-performance computing environments. Specifically, this cable is a 3 meter QSFP-DD to QSFP-DD passive copper cable, which means that it connects two devices with QSFP-DD ports using copper wires.
QSFP-DD (Quad Small Form-factor Pluggable Double Density) is a relatively new type of port that was developed to support faster data rates than the previous generation of QSFP ports. Specifically, QSFP-DD ports can support data rates of up to 400 Gbps (gigabits per second) using four lanes of 100 Gbps each.
The Cisco QDD-400-CU3M= cable is designed to support these high data rates over a distance of up to 3 meters (9.84 feet). It uses four lanes of copper wire to transmit data between the two QSFP-DD ports, and it does not require any external power source or additional components.
One advantage of using a passive copper cable like the QDD-400-CU3M= is that it is typically less expensive than other types of high-speed networking cables, such as active optical cables (AOCs) or fiber optic cables. However, passive copper cables do have some limitations. For example, they have a shorter maximum distance than AOCs or fiber optic cables, and they may be more susceptible to electromagnetic interference (EMI) and other forms of signal degradation.
Virtual and Augmented Reality
The Cisco QDD-400-CU3M= cable is a high-speed, low-latency copper cable designed to connect network switches, servers, and other networking equipment. It uses the QSFP-DD (Quad Small Form-factor Pluggable Double Density) interface, which supports data transfer rates of up to 400 Gbps. The cable is passive, which means it doesn't require any power or signal amplification to transmit data.
Virtual reality (VR) and augmented reality (AR) are technologies that create immersive and interactive digital environments for users. VR typically involves wearing a headset that covers the eyes and ears, while AR overlays digital information onto the real world using a camera or display device. These technologies are not directly related to networking equipment or cables, and there is no apparent connection between the Cisco QDD-400-CU3M= cable and VR/AR.
Definition and Specifications of 3 Meter Passive Cable
The Cisco QDD-400-CU3M= is a 3-meter long QSFP-DD (Quad Small Form-factor Pluggable Double Density) to QSFP-DD passive copper cable. It is used for high-speed data transmission between network devices, such as switches, routers, and servers.
Here are some of the key specifications of the Cisco QDD-400-CU3M=:
- Connector Type: QSFP-DD to QSFP-DD
- Cable Length: 3 meters (9.8 feet)
- Cable Type: Passive Copper Cable
- Data Transfer Rate: 400 Gigabit Ethernet
- Conductor Gauge: 28 AWG
- Operating Temperature Range: 0°C to 70°C (32°F to 158°F)
- Compatible with Cisco QSFP-DD switches and network devices
The QSFP-DD interface is a newer, high-density connector that is capable of transmitting data at speeds of up to 400 Gbps. Passive copper cables, like the Cisco QDD-400-CU3M=, are a cost-effective option for short-range data transmission within a data center or between nearby data centers.
The 28 AWG conductors used in this cable are designed to provide reliable data transmission over short distances while minimizing power consumption. The cable is compatible with Cisco's QSFP-DD switches and other network devices that use this connector type.

What is not covered by our warranty?
The reason why our warranty does not cover any problem caused by the following conditions:
(a) misuse of hardware; accidental damage; carelessness product(s) damage; shock; temperature beyond the specification of any product; faulty installation; operation; modification of goods;
(b) any misuse outside the instructions in the user manual for any specific product;
(c) damaged caused by other hardware or equipment. The warranty will void if the item is returned with physical damage, damage to the retail box, removed from the box, counterfeit labels/labelled by them, or any modifications of internal and external covers. Data loss or damages to any other equipment we do not cover by our offered warranty.
What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
Final Sale items are non-returnable/refundable in any situation. Any question? please ask our team before the shipment.
