Axiom CPAC-DAC-100G-1M-AX 100G QSFP28 DAC fibre optic cable 3.3ft

SKU CH-WC92-JCB9N MPN CPAC-DAC-100G-1M-AX

A 100 Gbps QSFP28 passive DAC cable with twinaxial construction, 3.3 ft length, and MSA compliance for OEM compatibility

  • 100 Gbps throughput via 100GBase-CR4 twinaxial copper
  • QSFP28 connectors on both ends for direct switch-to-switch links
  • 3 ft passive cable keeps rack cabling short and tidy
  • MSA-compliant coding ensures drop-in compatibility with OEM ports
  • Limited lifetime warranty backs long-term deployment confidence

100G QSFP28 Passive DAC Cable

This passive direct-attach cable carries 100GBase-CR4 traffic over twinaxial copper with QSFP28 connectors on both ends. It is built for short-reach links between switches, routers and servers inside the rack. The 3.3ft length suits adjacent or same-rack ports. Buyers who need longer reach or optical media should consider other cable types.

Check Port Compatibility And Coding

Verify that each end device accepts QSFP28 passive DACs and supports 100GBase-CR4 signalling. Confirm the switch or router firmware allows third-party coded modules; the cable carries an application-specific code for Check Point equipment. Ensure the port density and airflow direction leave enough clearance for the connector latch.

Twinax Construction With MSA Compliance

The black twinaxial assembly meets multi-sourcing agreement dimensions so it seats securely in any MSA-compliant QSFP28 cage. Passive design means no external power draw and no heat from active components. The latch mechanism gives a positive click and resists accidental disconnect during routine cable management. Limited lifetime warranty backs the build quality.

Questions about this item

Does the CPAC-DAC-100G-1M-AX ship with both QSFP28 ends attached or do I need separate transceivers?

The cable has QSFP28 connectors permanently fixed on both ends, so no extra transceivers are required.

The model list shows only a 3.3ft length — is that the sole option for this part number?

Yes, CPAC-DAC-100G-1M-AX is manufactured in a single 3.3ft length; other lengths carry different part numbers.

What does the 100G rating deliver when the cable is plugged into a switch?

It provides a 100GBase-CR4 twinaxial link up to 3.3ft with passive signalling and MSA-compliant pin-out.
