Product Features
Technical Overview
This 40GBASE-CR4 QSFP+ to 4 10GBASE-CU SFP+ cable operates as a passive DAC, meaning it requires no external power and has minimal signal processing. The twinaxial construction provides robust electrical performance with effective shielding against electromagnetic interference.
The cable terminates in a single QSFP+ connector on one end and four SFP+ connectors on the other, enabling breakout connectivity from a 40GbE port to four 10GbE ports. This configuration supports aggregation and distribution of network traffic across multiple devices.
Key Product Advantages
This DAC cable delivers several practical benefits for network administrators seeking reliable high-speed interconnects without the complexity of active components.
Cost-Effective Connectivity
As a passive solution, this cable eliminates the need for additional power and signal processing electronics, reducing both initial cost and long-term power consumption compared to active optical cables or transceiver-based solutions.
- No external power required
- Lower total cost of ownership
- Simplified deployment
High-Speed Breakout Capability
The QSFP+ to 4 SFP+ configuration enables efficient utilization of 40GbE ports by distributing bandwidth across multiple 10GbE connections, optimizing port density and network architecture flexibility.
- 40GbE to 4x10GbE breakout
- Port aggregation support
- Traffic distribution capability
Deployment / Use Cases
This cable is specifically designed for short-reach connections within data centers, server rooms, and networking closets where high bandwidth and low latency are critical.
Typical applications include connecting top-of-rack switches to servers, linking aggregation switches to access switches, and establishing inter-switch links in high-performance computing environments. The Chelsio compatibility makes it particularly suitable for networks utilizing Chelsio-based networking equipment.
Data Center Interconnects
Ideal for connecting switches and routers within the same rack or adjacent racks, providing reliable 40GbE connectivity with minimal signal degradation over the 3-meter distance.
Server Connectivity
Enables high-speed connections between servers and switches, supporting bandwidth-intensive applications and reducing network bottlenecks in virtualized environments.

FAQ
What type of cable is the Axiom OCTTAPCBL3M-AX?
The Axiom OCTTAPCBL3M-AX is a passive Direct Attach Copper (DAC) twinaxial cable. It features a 40GBASE-CR4 QSFP+ connector on one end and four 10GBASE-CU SFP+ connectors on the other end, providing a breakout solution for connecting 40GbE ports to multiple 10GbE ports without requiring external power or signal processing.
What is the maximum data transfer rate supported by this cable?
This cable supports a maximum data transfer rate of 40 gigabits per second (Gbit/s). The QSFP+ end operates at 40GbE, while the four SFP+ ends each support 10GbE, allowing for aggregate bandwidth distribution across multiple connections in breakout configurations.
Is this cable compatible with Chelsio networking equipment?
Yes, the Axiom OCTTAPCBL3M-AX is specifically designed to be compatible with Chelsio-based networking equipment. This ensures reliable interoperability and performance when used with supported Chelsio switches, routers, and network interface cards in data center and enterprise environments.
What does 'passive DAC' mean for this cable?
Passive DAC means this Direct Attach Copper cable operates without active electronic components for signal processing or amplification. It relies on the electrical properties of the twinaxial copper conductors to transmit signals, resulting in lower power consumption, reduced heat generation, and typically lower cost compared to active optical cables or transceiver-based solutions.
