40GBase-CU QSFP+ breakout cable

This passive twinax cable splits a single 40GBase QSFP+ port into four independent 10GBase SFP+ connections. It serves data-centre operators and network engineers who need short-reach, high-density links between switches, servers or host adapters without deploying fibre optics.

Passive copper limits reach and power

The cable operates without active signal conditioning, so its reliable distance is confined to the 13.12 ft length supplied. Passive twinax cannot equal the reach of active optical cables, and it adds no latency compensation or signal regeneration for longer runs.

Four 10 Gb/s channels aggregate to 40 Gb/s

Each SFP+ leg delivers 10 Gb/s, giving a combined 40 Gb/s throughput when all four channels are active. The assembly handles full 40GBase-CU and compatible InfiniBand traffic, but it cannot exceed the per-lane 10 Gb/s rate or the aggregate 40 Gb/s ceiling.

Questions about this item

Should I pick the 13.12 ft length or a shorter cable for my rack?

The 13.12 ft cable reaches across adjacent racks; choose a shorter length only if your QSFP+ and SFP+ ports are within the same rack to avoid excess slack.

What does the 40 Gbps total bandwidth mean when the cable is plugged into a switch?

The cable splits one 40 Gbps QSFP+ port into four independent 10 Gbps SFP+ links, so each connected server or switch port sees a full 10 Gbps channel.

Is the QSFP+ to 4x SFP+ breakout limited by the passive twinax design?

Yes, the passive twinax construction supports the rated 40 Gbps aggregate (4 × 10 Gbps) up to the 13.12 ft length without signal regeneration.
