Breakout Cable for 40G to 10G Links

This passive direct-attach cable splits a single 40G QSFP+ port into four independent 10G SFP+ connections. It is built for network engineers who need to disaggregate high-density uplinks without adding transceivers or active gear. The 10 ft twinaxial assembly reaches across adjacent rack units in standard cabinets. Buyers who require longer runs or active signal conditioning will need a different solution.

Passive Twinax Thermal Profile

Because the cable contains no active components, it draws negligible power and adds no measurable heat to the rack. Operation is completely silent, with no fans or electronic noise to consider in dense deployments. The 1.25 pound weight is supported entirely by the host cage latches. Installations that demand powered signal regeneration for extended reach cannot use this passive assembly.

Cisco-Coded Compatibility Label

The cable is programmed for Cisco equipment recognition, allowing the switch to identify the link and apply appropriate port policies without manual configuration. This coding removes the need for third-party workaround commands on supported platforms. Networks running non-Cisco operating systems that reject coded cables will not accept this assembly.

Questions about this item

How do I insert the QSFP+ end without damaging the latch?

Push the QSFP+ connector straight into the switch port until the pull-tab clicks; forcing it at an angle bends the internal pins.

When should I plan to replace this 10 ft passive DAC?

Replace it if the cable jacket shows kinks, the pull-tabs no longer latch, or link errors appear after rack moves.

What distance limit appears first when running 40 Gbps through this 10 ft assembly?

The 10 ft twinaxial length is the fixed reach; signal integrity drops beyond that without active optics.
