Product Features
Technical Overview
This active optical cable features a QSFP28 connector on one end that breaks out to four SFP28 connectors on the opposite end, enabling flexible connectivity configurations. The 100GBASE-AOC specification supports full-duplex 100 Gbit/s throughput, making it suitable for backbone connections, data center interconnects, and high-performance computing networks.
Active Optical Technology (AOT) converts electrical signals to optical signals within the cable assembly, eliminating the need for separate transceivers at each connection point. This integrated approach reduces points of failure and simplifies cable management while maintaining compatibility with standard QSFP28 and SFP28 port specifications.
Key Product Advantages
This AOC cable provides several advantages over traditional copper or passive optical solutions. The active optical design ensures consistent performance across the entire 20-meter length without signal degradation, while the integrated transceivers reduce overall system cost and complexity.
Simplified Deployment
Pre-terminated with factory-tested connectors, this cable eliminates the need for field termination or separate transceiver installation, reducing deployment time and potential configuration errors.
- No separate transceivers required
- Factory tested for reliability
- Plug-and-play installation
Enhanced Reliability
Active optical technology provides superior signal integrity compared to passive copper cables, especially over longer distances where electrical signal attenuation can impact performance.
- Lower bit error rates
- Reduced electromagnetic interference
- Consistent performance across temperature variations
Space and Power Efficiency
The integrated design consumes less power than discrete transceiver solutions and requires less rack space, contributing to overall data center efficiency.
- Lower power consumption
- Reduced cable bulk
- Improved airflow management
Deployment / Use Cases
This QSFP28 to 4x SFP28 breakout cable is ideal for connecting high-density switches with 100GbE QSFP28 ports to devices with 25GbE SFP28 interfaces. The 20-meter length provides flexibility in data center layouts where equipment may be separated across racks or within the same row.
Common deployment scenarios include connecting leaf-spine network architectures, aggregating server connections in hyper-converged infrastructure, and extending storage network connections between storage arrays and servers. The Cisco compatibility ensures broad interoperability with existing network infrastructure from one of the industry's leading networking vendors.
Data Center Interconnect
Connect top-of-rack switches with 100GbE QSFP28 uplinks to servers with 25GbE SFP28 interfaces, enabling efficient bandwidth utilization and simplified cabling in high-density environments.
Network Aggregation
Consolidate multiple 25GbE connections into a single 100GbE port, reducing port utilization on core switches while maintaining full bandwidth capacity for aggregated traffic flows.

FAQ
What is the difference between this AOC cable and a standard DAC cable?
This Active Optical Cable (AOC) uses fiber optic strands with integrated optical transceivers to convert electrical signals to light, while Direct Attach Copper (DAC) cables use copper conductors with passive electrical signaling. AOCs typically support longer distances (this cable is 20m/65.6 ft), have lower weight and bulk, and are immune to electromagnetic interference, making them better suited for data center environments where these factors matter.
Is this cable compatible with non-Cisco network equipment?
While specifically tested and verified for Cisco compatibility, this QSFP28 to 4x SFP28 AOC cable uses standard 100GBASE-AOC specifications that should work with any network equipment supporting QSFP28 and SFP28 interfaces. The cable follows industry-standard electrical and optical specifications, but for optimal performance, verify compatibility with your specific switch or router model's transceiver compatibility list before deployment.
What types of network devices can I connect with this breakout cable?
This cable connects a device with a QSFP28 port (typically a switch or router) to four devices with SFP28 ports. Common applications include connecting a 100GbE switch to four 25GbE servers, aggregating multiple storage arrays to a single switch port, or linking network appliances with different interface speeds. The cable supports network devices, switches, and routers as specified in the technical documentation.
How does the lifetime warranty work for this network cable?
Axiom provides a lifetime limited warranty that covers defects in materials and workmanship for the duration of the product's life. This warranty typically includes repair or replacement of the cable if it fails under normal use conditions. Warranty claims generally require proof of purchase and may exclude damage from improper installation, physical abuse, or unauthorized modifications. Contact Axiom Memory Solutions for specific warranty terms and claim procedures.
