Frequently Asked Questions

What is the difference between an active and passive direct attach cable?

An active direct attach cable (DAC) includes electronic components to boost and condition the signal, allowing for longer reach than passive DACs. This 7-meter cable is active, ensuring signal integrity over its full length for 40 Gigabit Ethernet.

Is this cable compatible with non-Cisco QSFP+ equipment?

While specifically designed and tested for Cisco QSFP-H40G-ACU7M compatibility, this cable also complies with MSA (Multi-Source Agreement) industry standards. This compliance generally ensures broader compatibility with other QSFP+ devices that adhere to MSA specifications, though Cisco validation is its primary assurance.

Can this cable be used for 10 Gigabit Ethernet applications?

This cable is engineered for 40 Gigabit Ethernet (40GbE) applications. While some 40GbE QSFP+ ports can be configured to break out into 4x10GbE SFP+ connections with specific breakout cables and transceivers, this particular cable is a direct 40GbE QSFP+ to QSFP+ link and is not designed for 10GbE breakout use.

What is the jacket material of this cable?

The jacket material of the StarTech.com QSFPH40GACU7 cable is Polyvinyl chloride (PVC). This material provides durability and flexibility, suitable for typical data center and network closet environments.
