Axiom CPAC-DAC-100G-2M 100G QSFP28 DAC cable 2m

SKU CH-HEDT-67HAJ MPN CPAC-DAC-100G-2M

A 2 metre passive QSFP28 direct-attach cable delivering 100 Gbps connectivity with MSA compliance and OEM-coded compatibility

  • 100 Gbps throughput for high-density switching
  • 2-metre passive reach simplifies rack cabling
  • Check Point coded for guaranteed OEM interoperability
  • MSA-compliant design fits any QSFP28 port
  • Pre-serialised units prevent link identification errors

100G QSFP28 DAC cable for Check Point gear

This passive twinax cable provides a 100GBASE-CR4 link between compatible switches and routers. It is built for data-centre racks where short-reach, low-latency connections are required. The two-metre length suits adjacent or same-rack equipment.

Pre-coded EEPROM removes manual configuration

Each end carries an application-specific code that matches Check Point OEM requirements, so the link comes up without user intervention. MSA compliance means the same cable also works in other multi-vendor 100G QSFP28 ports. Unique serialization prevents address conflicts in dense patches.

Push-pull latching enables tool-free install

Insert the modules until the latch clicks; removal uses the same squeeze motion. The stiff twinax jacket demands a gentle bend radius — forcing tight bends can fracture the copper pairs. Verify port orientation before seating to avoid bent cages.

Questions about this item

How often does the passive twinax copper assembly need replacement in a 100 GbE link?

Passive copper has no active components to wear out; replacement is only needed if the cable is physically damaged or the QSFP28 latch fails.

What limits maximum reach when the link runs continuously at 100 Gbps?

The 2 m passive design is the reach limit; signal loss grows with length, so longer runs require active or optical cables instead.

How much heat does the cable add to a rack when it carries 100 Gbps all day?

Passive DACs draw no power and generate negligible heat; the only thermal load comes from the switch ports on each end.
