Axiom 40GBASE-CR4 QSFP+ Passive DAC Cable Meraki Compatible 5m cpu accessory

SKU CH-29ED-W5CJP

A 5-metre passive QSFP+ direct-attach cable carrying 40 Gbps links between Meraki-compatible switches and routers

  • 40 Gbps direct-attach speed for high-bandwidth links
  • 5 metre passive copper reach up to 10 metres
  • QSFP+ male connectors fit MSA-compliant ports
  • Pre-coded for Meraki gear to avoid conflicts
  • Guaranteed OEM compatibility with unique serialisation

Direct-attach 40 Gbps cable

The Axiom 40GBASE-CR4 QSFP+ passive DAC cable provides a 5 metre copper link for high-speed network connections. It is built for data-centre and enterprise environments that need reliable 40 gigabit throughput between switches, routers or servers. The cable arrives new and carries a unique serialisation for simple asset tracking.

Pre-coded for Meraki gear

Each assembly is pre-configured with an application-specific code that matches Meraki OEM requirements, eliminating communication conflicts at power-up. The passive twinax design requires no external power and is fully compliant with the multi-sourcing agreement, so it also functions in other MSA-compliant platforms without extra setup.

Handles 40 Gbps up to 10 metres

The twinax construction supports the full 40 Gbps rate across the 5 metre length and remains within specification for runs up to 10 metres. It is not suited for links that exceed that distance or for applications demanding active optical reach. Buyers needing longer spans or different connector types should look elsewhere.

Questions about this item

Does the passive twinax cable require any firmware updates or connector maintenance over time?

No firmware updates or connector maintenance are required; the cable is pre-configured with an application-specific code and fully MSA compliant for plug-and-play operation.

What length limit applies before signal degradation appears on a 40GBASE-CR4 passive link?

The passive twinax design supports reliable operation up to 10 meters, so the 5-meter length stays well within the specified reach for high-speed data transfer.

How much heat or power does the cable add when running continuously in a Meraki switch?

As a passive twinax assembly it draws no external power and generates negligible heat, adding no thermal load to the switch during all-day operation.
