Direct Attach 100G Link

This Axiom twinaxial cable provides a 100GBASE-CR4 connection between two QSFP28 ports. It is built for data-centre racks and high-performance compute clusters that need short-reach, low-latency links. The black, shielded assembly arrives new and ready for immediate deployment.

QSFP28 Male-to-Male Interface

Both ends carry a QSFP28 male connector wired for the 100GBASE-CR4 electrical specification. This single interface detail determines whether the cable matches your switch, NIC or transceiver slot; no other connector or protocol is supported.

Rack-Level Integration

The twinaxial construction keeps the link inside a single rack or adjacent racks without optical transceivers, freeing both power budget and front-panel density. It requires matching QSFP28 cages on each device and a clear cable-routing path; longer runs or cross-building links are outside its design scope.

Questions about this item

What does the 100GBASE-CR4 rating mean for actual throughput?

The cable supports 100 Gb/s aggregate bandwidth across four 28 Gb/s lanes when connected to compatible QSFP28 ports.

Which interface standard does the QSFP28 connector follow and what does it limit?

The QSFP28 Male Network connectors comply with the 100GBASE-CR4 electrical specification, capping each lane at 28 Gb/s for a total of 100 Gb/s.

What physical clearance is needed to plug the QSFP28 ends into a switch?

Each end uses a standard QSFP28 male form factor; allow enough rack depth for the cable bend radius and the connector latch to engage fully.
