Reliability

The Cisco QSFP-H40G-CU3M 3 Meter Direct-Attach Copper Cable is a high-performance, reliable solution for connecting QSFP (quad small form-factor pluggable) ports on Cisco switches and other devices. It uses 40 Gigabit Ethernet (40 GbE) technology and has a maximum data transfer rate of 40 Gbps. The cable is made of copper and is 3 meters long, which allows for flexible installation options in data centers and other network environments.

One of the key features of this product cable is its reliability. Direct-attach copper (DAC) cables, such as this one, provide a more reliable and cost-effective solution for short-distance data transfer than optical transceivers. Because they use copper wires instead of optical fibers, DAC cables are less susceptible to signal loss or interference, which can result in a more stable and reliable connection. Additionally, because they do not require the use of optics, they are less complex and less expensive than optical transceivers, which can make them more reliable in the long term.
