Product Features
Technical Overview
This active optical cable integrates electrical-to-optical conversion directly within the cable assembly, eliminating the need for external transceivers and simplifying deployment. The QSFP+ end features a single 40 GbE connector that breaks out into four independent SFP+ connectors, each capable of 10 GbE data transfer, supporting an aggregate bandwidth of 40 Gbit/s.
The cable uses multi-mode fiber (MMF) with an 850nm wavelength, optimized for short-distance, high-bandwidth applications within data centers, server rooms, and network closets. AOC technology ensures robust performance with lower power consumption and reduced heat generation compared to traditional copper DAC cables, while maintaining high signal integrity over the full 15-meter length.
Key Product Advantages
This AOC cable delivers several key benefits for modern network environments, combining high-speed performance with operational simplicity and compliance assurance.

- Eliminates external transceivers
- Plug-and-play deployment
- Reduces cable clutter
High-Speed Performance
Supports 40 GbE aggregate bandwidth with low latency and reliable data transmission, ideal for bandwidth-intensive applications and high-density network setups.
- 40 Gbit/s data rate
- Low signal degradation
- Optimized for short-reach MMF
Compliance & Reliability
TAA compliant and manufactured in the United States, meeting regulatory requirements for government and enterprise procurement, backed by a lifetime warranty for long-term reliability.
- TAA compliant
- U.S. origin
- Lifetime warranty
Deployment / Use Cases
This cable is engineered for scenarios requiring high-bandwidth connections between network switches, servers, and storage systems, particularly in environments where 40GbE uplinks need to be distributed to multiple 10GbE devices.
Common use cases include connecting Arista Networks switches with QSFP+ ports to servers or storage arrays with SFP+ ports, aggregating 10GbE links into 40GbE uplinks in top-of-rack configurations, and extending 40GbE connections within data center racks where traditional copper DAC cables may face length or interference limitations. The 15-meter reach makes it suitable for intra-rack and adjacent-rack deployments without signal boosters.
Data Center Aggregation
Connect 40GbE switch uplinks to multiple 10GbE servers or storage devices, optimizing rack space and reducing port utilization on core switches.
Network Infrastructure Expansion
Extend 40GbE connections between switches or to network appliances, leveraging AOC technology for reliable performance over medium distances.

FAQ
What is the difference between this AOC cable and a traditional DAC cable?
This active optical cable (AOC) uses fiber optics with integrated electrical-to-optical conversion, offering longer reach (up to 15m), lower weight, and better resistance to electromagnetic interference compared to direct attach copper cables (DAC). AOCs are ideal for environments where signal integrity over medium distances is critical, while DACs are typically used for shorter connections within the same rack.
Is this cable compatible with non-Arista network devices?
Yes, this cable is designed to be compatible with any network device that supports standard QSFP+ and SFP+ interfaces. While it is verified for Arista Networks switches, it should work with other brands that adhere to the same industry standards for 40GBase-AOC and 10GbE SFP+ connections, but always check your device's compatibility list for optimal performance.
What does TAA compliant mean for this product?
TAA (Trade Agreements Act) compliance indicates that this cable is manufactured in the United States or another designated country, making it eligible for procurement by U.S. government agencies and contractors. This ensures the product meets specific regulatory requirements for origin and quality, which is essential for public sector and enterprise deployments where compliance is mandatory.
How does the QSFP+ to 4xSFP+ breakout functionality work?
The cable converts a single 40 GbE QSFP+ port into four independent 10 GbE SFP+ channels. This allows you to connect one 40GbE uplink on a switch to four separate 10GbE devices, such as servers or storage units, effectively aggregating bandwidth and optimizing port usage. The breakout is handled internally by the AOC technology, requiring no additional configuration on the network devices.
What is the maximum distance this cable can support reliably?
This cable is designed for reliable performance up to 15 meters (49.2 feet) using multi-mode fiber with an 850nm wavelength. It is optimized for short-reach applications within data centers, server rooms, or between adjacent racks. For longer distances, single-mode fiber or different transceiver types may be required, but this AOC provides a robust solution for typical intra-rack and nearby rack connections.
Does this cable support DOM or DDM monitoring features?
product details do not include details on DOM (Digital Optical Monitoring) or DDM (Digital Diagnostic Monitoring) support. This AOC cable focuses on core connectivity with QSFP+ to SFP+ breakout functionality. For monitoring capabilities, check the product documentation or manufacturer specifications, as some AOC models may include these features for real-time performance tracking.
