Frequently Asked Questions
Is this cable compatible with non-Cisco QSFP+ equipment?
Yes, while designed for Cisco compatibility, this cable also complies with MSA (Multi-Source Agreement) industry standards, making it compatible with other MSA-compliant QSFP+ devices.
What is the advantage of a direct attach copper (DAC) cable over fiber optic transceivers?
DAC cables offer a more cost-effective and lower-power solution for short-distance connections (typically up to 7 meters) compared to fiber optic transceivers, making them ideal for in-rack or adjacent rack links.
Can this cable be used for 10 Gigabit Ethernet connections?
This specific cable is designed for 40 Gigabit Ethernet. While some QSFP+ ports can break out to 4x10G, this cable is a single 40G link and would require specific hardware support for 10G breakout.
What is the jacket material of this cable?
The cable features a Polyvinyl chloride (PVC) jacket, providing durability and protection for the copper conductors in various operating environments.
