1 m cable length
Juniper compatible
Male connector configuration

Keep short-reach 100G interconnects simple with this Axiom passive DAC breakout cable. Designed for Juniper-compatible environments, it converts a single QSFP28 port into four SFP28 connections over a 1 m copper assembly, making it a practical fit for high-density leaf-spine and top-of-rack designs. Passive direct attach copper is the right choice when you want predictable short-distance performance without the added cost and power draw of optics. The breakout format helps you fan out bandwidth from a 100G uplink to multiple 25G endpoints, reducing transceiver count and simplifying port planning in constrained racks. At 1 m, this cable is intended for adjacent equipment and tightly organized enclosures where excess slack creates airflow and serviceability issues. It is a straightforward way to preserve signal integrity across short runs while keeping deployment costs under control. For teams standardizing on Juniper-compatible infrastructure, this cable supports a cleaner, lower-overhead path to 100G aggregation and 25G access connectivity.

Ideal For

Connect a 100G switch uplink to four 25G server or appliance ports
Link adjacent rack equipment in a top-of-rack or leaf-spine layout
Reduce transceiver spend in short-distance aggregation deployments
Standardize breakout cabling in Juniper-compatible network environments

Why This Product

1Passive copper avoids optical transceiver costs for short runs

Frequently Asked Questions

What does QSFP28 to 4 SFP28 mean?▾

It means one 100G QSFP28 port breaks out into four 25G SFP28 connections, which is useful for distributing bandwidth across multiple endpoints.

Is this cable active or passive?▾

It is a passive DAC, so it does not include active electronics in the cable assembly.

What environments is a 1 m DAC best for?▾

A 1 m DAC is best for adjacent rack or same-rack connections where equipment is close together and cable slack needs to stay minimal.

Why choose DAC instead of optics?▾

For short-reach links, DAC typically reduces cost, power draw, and component count while keeping the connection simple and predictable.
