Product Features
Technical Overview
This cable operates at a data transfer rate of 100 Gbit/s, supporting high-speed network traffic between compatible devices. The QSFP28 connector interfaces with 100GbE ports, while the four SFP28 connectors each handle 25GbE links, allowing aggregation or distribution of network bandwidth.
The twinaxial copper construction provides stable electrical performance for distances up to 10 meters, with this specific model optimized for 3-meter runs. The passive architecture eliminates active components, reducing power consumption and potential points of failure in the link.
Key Product Advantages
This cable simplifies high-speed network connectivity by eliminating the need for separate transceivers and fiber patch cables. The direct-attach copper design provides a plug-and-play solution that reduces installation complexity and total cost of ownership.
Density Optimization
The breakout configuration allows a single 100GbE port to connect to four 25GbE devices, maximizing port utilization in switches and routers.
- QSFP28 to 4x SFP28 breakout
- 100GbE to 25GbE aggregation

FAQ
What type of cable is the Axiom CX-DAC-4SFP25G-3M-AX?
This is a passive direct-attach copper (DAC) breakout cable with twinaxial construction. It features a QSFP28 connector on one end that breaks out to four individual SFP28 connectors, designed for connecting 100GbE ports to 25GbE devices without requiring separate transceivers.
What is the maximum data transfer rate supported by this cable?
The cable supports a data transfer rate of 100 Gbit/s (100GbE). The QSFP28 end handles the full 100GbE bandwidth, while each of the four SFP28 connectors supports 25GbE, allowing the cable to aggregate or distribute network traffic between different speed interfaces.
What devices are compatible with this breakout cable?
The cable is compatible with network devices, routers, and switches that support QSFP28 and SFP28 interfaces. This includes enterprise switches with 100GbE ports connecting to servers, storage arrays, or other network equipment with 25GbE network interface cards.
What does 'passive' mean for this DAC cable?
Passive means the cable contains no active electronic components or signal conditioning circuitry. It relies on the electrical properties of the twinaxial copper conductors to transmit signals, which eliminates external power requirements and reduces potential points of failure compared to active cables or optical solutions.
