Axiom QSFP+ to four SFP+ twinaxial direct attach cable, 4 metres

Axiom

Axiom QSFP-4SFP10G-CU4M-AX 40Gbps QSFP+ to 4x 10Gbps SFP+ 4m fibre optic cable

SKU CH-SMN0-NB0EH MPN QSFP-4SFP10G-CU4M-AX

Splits a 40 Gbps QSFP+ port into four 10 Gbps SFP+ links over a 13 ft passive twinaxial cable with full OEM compatibility

  • 40 Gbps aggregate bandwidth from one QSFP+ to four 10 Gbps SFP+ ports
  • 4 metre twinaxial reach links adjacent rack equipment without transceivers
  • Passive copper construction draws no power and adds no latency
  • MSA compliant design guarantees interoperability with multi-vendor switches and routers
  • 100 % OEM compatibility pre-programmed for drop-in Cisco QSFP-4SFP10G-CU1M replacement

Direct-attach breakout cable

This passive twinaxial cable splits a single 40Gbps QSFP+ port into four independent 10Gbps SFP+ connections. It is built for data-centre operators and network engineers who need to link a high-density switch uplink to multiple downstream servers or appliances. The 4-meter length suits adjacent rack connections in standard cabinets.

Check port type and switch code

Verify that the upstream device presents a QSFP+ interface and that the downstream gear uses SFP+ transceivers or fixed ports. Confirm the switch or router firmware accepts third-party direct-attach cables and that the breakout mode is enabled in the operating system. The passive design requires no external power but does not amplify signals beyond the rated reach.

MSA-compliant twinax construction

The cable meets Multi-Source Agreement mechanical and electrical specs, so it seats securely in any compliant cage without adapter brackets. Passive copper twinax keeps latency low and eliminates the failure points of active optics. Each end carries a serialized part number for inventory tracking and OEM qualification. The 13-foot run stays within the passive reach envelope for 10Gbps lanes.

Questions about this item

Does the package include the QSFP+ and four SFP+ connectors, or must they be purchased separately?

The cable ships with a QSFP+ male connector on one end and four SFP+ male connectors on the other, so no separate transceivers are required.

The listing shows a single 4-metre length — is that the only option available?

Yes, this part number is supplied only as a 4-metre (13.12 ft) twinaxial direct-attach cable.

What does the 40 Gbps rating mean when the cable is installed in a switch?

It provides a 40GBase-CR4 link that splits into four independent 10 Gbps channels, each carried over its own SFP+ connection.
