Product Features
Technical Overview
This QSFP+ direct attach cable implements the 40GBASE-CR4 standard, which specifies four lanes of 10 Gb/s over copper twinaxial cable. The passive design means no signal regeneration electronics are built into the cable assembly, resulting in lower power consumption and reduced heat generation compared to active optical cables.
The cable maintains signal integrity across its 16.4-foot length while supporting the full 40 Gb/s bandwidth. QSFP+ connectors provide a compact, high-density interface that's hot-pluggable in compatible equipment, allowing for maintenance and reconfiguration without system downtime.
Key Product Advantages
This direct attach cable offers several practical benefits for network deployments. The passive design provides reliable connectivity without additional power requirements, while the QSFP+ interface ensures compatibility with a wide range of 40GbE network equipment.
Cost-Effective Connectivity
Eliminates the need for separate optical transceivers, reducing overall connection costs for short-distance links within data centers or between network switches.
- No transceiver modules required
- Lower total cost of ownership
- Simplified inventory management
Reliable Performance
Passive copper construction ensures stable signal transmission up to 16.4 feet while maintaining full 40 Gb/s bandwidth with minimal latency.
- Consistent 40 Gbit/s throughput
- Low signal latency
- Stable electrical connection
Deployment / Use Cases
This QSFP+ DAC cable is designed for specific networking scenarios where short-distance, high-speed connections are required between compatible devices.
In data center environments, the cable connects top-of-rack switches to servers or storage arrays within the same rack. For network infrastructure, it links aggregation switches to core switches in adjacent racks or within the same equipment row. The cable also supports high-performance computing clusters where low-latency, high-bandwidth interconnects are critical between compute nodes.
Data Center Interconnects
Connect leaf switches to spine switches within the same rack or adjacent racks, providing 40GbE backbone connectivity for modern data center fabrics.
Server-to-Switch Connections
Link high-performance servers with 40GbE network interfaces to top-of-rack switches, ensuring adequate bandwidth for virtualization, storage, and application workloads.

FAQ
What type of cable is the Axiom 10323-AX?
The Axiom 10323-AX is a 40GBASE-CR4 QSFP+ passive direct attach copper cable (DAC). This means it's a copper twinaxial cable with QSFP+ connectors permanently attached at both ends, designed for short-distance 40GbE connections without requiring separate optical transceivers or active signal regeneration electronics.
What is the maximum data transfer rate supported by this cable?
This cable supports data transfer rates up to 40 Gbit/s (40 gigabits per second). It implements the 40GBASE-CR4 standard, which uses four lanes of 10 Gb/s each over copper media, providing full 40GbE bandwidth for high-performance network connections between compatible switches, servers, or storage devices.
How long is the Axiom 10323-AX QSFP+ cable?
The cable measures 16.4 feet in length, which is equivalent to 5 meters. This length is ideal for connections within the same rack, between adjacent racks, or for equipment positioned within close proximity in data center or server room environments where short-reach 40GbE links are required.
What does 'passive' mean for this direct attach cable?
Passive means the cable contains no active signal regeneration or retiming electronics. The signal travels directly through the copper conductors without amplification, which results in lower power consumption, reduced heat generation, and typically lower cost compared to active optical cables. Passive DAC cables are designed for shorter distances where signal integrity can be maintained without electronic assistance.
