Frequently Asked Questions
What is the primary advantage of an active direct attach cable (DAC) over a passive DAC?
Active DACs, like the StarTech.com QSFPH40GACU5, incorporate signal conditioning electronics to boost the signal, allowing for longer cable lengths (up to 7 meters for 40G) compared to passive DACs, which are typically limited to 1-3 meters. This extends deployment flexibility while maintaining copper's cost benefits.
Is this cable compatible with non-Cisco 40GbE equipment?
Yes, while designed and tested for Cisco QSFP-H40G-ACU5M compatibility, this cable also complies with MSA (Multi-Source Agreement) industry standards. This ensures broad interoperability with other brands of QSFP+ compliant 40 Gigabit Ethernet switches and network adapters.
What is the jacket material of this cable?
The StarTech.com QSFPH40GACU5 features a durable Polyvinyl chloride (PVC) jacket. This material provides good flexibility and protection for the copper conductors within typical data center and server room environments.
Can this cable be used for InfiniBand applications?
Yes, the product specifications indicate that this cable supports the InfiniBand protocol. This makes it suitable for high-performance computing (HPC) clusters and other environments requiring extremely low-latency, high-bandwidth interconnects beyond standard Ethernet.
