Direct-Attach 40GbE Cable

The RUCKUS WIRELESS E40G-QSFP-QSFP-P-030 is a passive copper cable with QSFP+ connectors on both ends. It provides a 40GbE direct-attach link for switches, routers or servers that use QSFP+ ports. The three-metre length suits rack-to-rack or intra-rack connections in commercial network environments.

Thermals Noise Power

Passive copper construction means the cable draws no power and generates no heat of its own. No active electronics or fans are present, so operation is completely silent. The assembly simply conducts the signal between two QSFP+ ports without adding to the thermal or acoustic load of the rack.

Upgrade Context

This cable replaces shorter or longer passive DACs when the three-metre reach matches the physical layout. It upgrades from lower-speed direct-attach cables when the connected equipment moves to 40GbE QSFP+ interfaces. The jump is worth it when port density and latency requirements call for a native copper link rather than optical transceivers.

Questions about this item

How do I install the E40G-QSFP-QSFP-P-030 passive DAC cable and what step is often missed?

Align each QSFP+ connector with the port, push straight in until the latch clicks, then verify the link LED lights on both ends; the step often missed is fully seating the latch so the cable cannot pull loose.

What maintenance or replacement will the 3 m passive copper cable need later?

No scheduled maintenance is required; replace the cable only if the connectors are damaged, the cable is kinked, or link errors appear after reseating both ends.

What limit appears first on this 40 GbE passive DAC during sustained use?

The 3 m passive copper reach is the primary limit; beyond that distance signal integrity degrades and an active or optical cable would be needed.
