Cloud service providers rely on efficient networking solutions to deliver seamless and responsive services to their users. The QSFP-H40G-CU3M= cable contributes to the reliability and performance of cloud infrastructure by providing a high-speed, low-latency connection between network elements.

As networking technologies continue to evolve, it's essential to consider future trends and advancements. The QSFP-H40G-CU3M=, with its high-speed capabilities and compatibility features, positions itself as a relevant solution in the context of emerging technologies such as 5G, edge computing, and the growing demand for higher bandwidths.

The Cisco QSFP-H40G-CU3M= is a high-performance direct-attach copper cable that is designed to provide high-bandwidth connections in data centers and other high-performance computing environments.

This cable has a data rate of 40 Gbps, which is a significant improvement over previous generations of cables that had lower data rates. This high data rate allows for faster data transfer, enabling large amounts of data to be moved quickly and efficiently.

The cable is 3 meters in length and uses QSFP+ connectors on each end, which are compact and high-speed connectors that can support data rates of up to 40 Gbps. The QSFP+ connector is hot-pluggable, which allows devices to be added or removed from the network without interrupting the network.

The twin axial copper cable that is used in this product has been specifically designed to meet the requirements of high-performance computing environments. It is built to a high standard of quality, with low attenuation and crosstalk, ensuring that the signal stays strong and the data is transmitted accurately.

It also has a wide operating temperature range of 0 to 70 degrees Celsius (32 to 158 degrees Fahrenheit) and 5 to 95% non-condensing operating humidity range.

Resiliency and High Availability

The Cisco product 3 Meter Direct-Attach Copper Cable is designed to provide resiliency and high availability in data center and other network environments.

Resiliency refers to the ability of a system or network to continue functioning despite the presence of faults or failures. In the case of this product cable, its direct-attach copper (DAC) design allows for a more stable and reliable connection than optical transceivers, which can be affected by signal loss or interference. Additionally, its high-performance, 40 GbE technology allows for faster data transfer and recovery in the event of a failure.

High availability (HA) refers to the ability of a system or network to provide uninterrupted service in the event of a failure. This product cable's resiliency, combined with Cisco's reputation for quality and reliability, can help to ensure that the connection between devices remains stable and functioning.

Moreover, these product cables are also compliant with IEEE 802.3ba standards, which ensures that they are designed to meet the high availability and reliability requirements in data center environments.
