Product Features
Technical Overview
This cable adheres to the 100GBASE-CR4 standard, utilizing a QSFP28 connector on one end and four SFP28 connectors on the other to break out a single 100 GbE link into four 25 GbE channels. The twinaxial copper construction offers robust electrical performance with minimal signal loss, suitable for distances up to 5 meters without active signal conditioning.
The passive DAC architecture provides plug-and-play functionality, requiring no configuration or management software. It supports hot-pluggable installation, allowing for easy deployment and maintenance without network downtime. The cable is backward compatible with lower-speed interfaces where supported by the connected devices, offering flexibility in mixed-speed environments.

FAQ
What is the maximum distance supported by this DAC cable?
This Axiom passive DAC cable supports a maximum distance of 5 meters (16.4 feet). It is designed for short-reach applications within data center racks or between adjacent racks, providing reliable high-speed connectivity without signal degradation over this length. For longer distances, active optical cables or fiber transceivers would be required.
Is this cable compatible with non-Fortinet network equipment?
While specifically validated for Fortinet compatibility, this 100GBASE-CR4 QSFP28 to 4 SFP28 passive DAC cable may work with other vendors' equipment that supports the same standard. However, compatibility is not guaranteed, and it is recommended to verify with the device manufacturer or test in your specific environment before deployment.
What does 'passive DAC' mean for this cable?
Passive DAC (Direct Attach Copper) means the cable contains only copper wires without any active electronic components for signal conditioning or retiming. This results in lower power consumption, reduced latency, and higher reliability compared to active cables. It is ideal for distances up to 5 meters where signal integrity can be maintained passively.
Can this cable be used for breakout from 100 GbE to 10 GbE ports?
No, this cable is specifically designed for 100GBASE-CR4 to 4 x SFP28 breakout, supporting 25 GbE per SFP28 port. It is not compatible with 10 GbE SFP+ ports due to different electrical specifications. For 100 GbE to 10 GbE breakout, a different cable or transceiver solution would be required.
