Axiom
Axiom JNP-100G-DAC-1M-AX 100G QSFP28 Twinax 3.3 ft
A 100 Gbps passive twinax cable with QSFP28 connectors on both ends, 3.3 ft long
- 100Gbps throughput with QSFP28 connectors
- Passive twinax design requires no external power
- 3 ft reach for close-range rack links
- Direct-attach cable cuts transceiver cost and latency
- Pre-terminated ends enable plug-and-play deployment
Axiom 100G QSFP28 Twinax Cable
This Axiom direct attach cable provides a 100GbE link between two QSFP28 ports using passive twinaxial copper. It is built for short-reach connections inside racks or between adjacent cabinets where fibre is not required. The 3.3 ft length suits dense top-of-rack or leaf-spine layouts.
Ideal for high-density 100GbE interconnects
Network engineers deploying 100GbE switches, routers or servers with QSFP28 cages will use this cable for low-latency, low-power links up to 3.28 ft. It does not suit runs that exceed the passive copper reach or installations that require active optical transceivers for longer distances. Buyers needing fibre media or breakout configurations should select a different product type.
Verify QSFP28 port compatibility and length budget
Confirm that both ends of the link present QSFP28 interfaces rated for 100Gbase direct attach copper. Measure the exact patch-path distance to ensure the 3.28 ft cable reaches without strain or excess slack. Check that the switch or NIC firmware lists this part number as a supported passive cable before ordering.

Questions about this item
What QSFP28-equipped network devices must I already own to use this 100G 3.3 ft passive twinax cable?
You need two network devices that each provide a QSFP28 port supporting 100G direct-attach copper, such as compatible switches, routers or NICs with matching cages.
Can this 100G QSFP28 twinax cable interoperate with legacy 28G QSFP+ ports on older equipment?
No, the cable terminates in QSFP28 connectors designed for 100G signalling; QSFP+ ports operate at different lane speeds and are not electrically compatible.
How can I verify the link is operating at the intended 100G rate after connecting the 3.28 ft passive twinax cable?
Check the port status on both connected devices — they should report a 100G link up with no errors, and the interface counters should show traffic flowing at line rate.
