Product Features
Technical Overview
This active optical cable implements AOC (Active Optical Cable) technology, integrating electrical-to-optical conversion at each connector end to maintain signal quality across the entire 15-meter span. The 40 Gbit/s data transfer rate supports modern high-bandwidth applications including server clustering, storage area networks, and backbone interconnects.
The cable features a QSFP+ connector on one end that breaks out to four individual SFP+ connectors, enabling flexible deployment scenarios where a single 40GbE port needs to connect to multiple 10GbE devices. This breakout capability is particularly valuable in top-of-rack switching environments and distributed computing architectures.
This section brings together practical product details such as Cable Type, Fiber Optic Mode, Cable Length, Country of Origin, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

Deployment / Use Cases
This 40GBase-AOC cable is ideal for data center environments where high-density connectivity and reliable performance are critical. The QSFP+ to 4xSFP+ breakout configuration enables efficient utilization of switch ports while maintaining full 40GbE bandwidth capabilities.
Common deployment scenarios include connecting top-of-rack switches to server racks, establishing backbone links between network distribution layers, and implementing high-performance computing clusters. The 15-meter reach provides sufficient flexibility for most rack-to-rack and within-rack connections without requiring intermediate patch panels or additional signal conditioning.
Data Center Interconnect
Connect 40GbE switches to multiple 10GbE servers or storage arrays using a single cable, reducing cable clutter and simplifying cable management in high-density environments.
Network Backbone
Establish reliable 40GbE links between core switches and distribution layers with the signal integrity advantages of active optical technology over medium-distance runs.

FAQ
What type of cable is the AddOn 721076-B21-AO?
The AddOn 721076-B21-AO is an active optical cable (AOC) that uses fiber optic technology to transmit data. It features a QSFP+ connector on one end that breaks out to four SFP+ connectors on the other end, supporting 40 Gbit/s data transfer rates over 850nm multimode fiber with a 15-meter reach.
What does TAA compliant mean for this cable?
TAA (Trade Agreements Act) compliance indicates this cable meets specific manufacturing and sourcing requirements for government procurement. Being TAA compliant makes it suitable for federal, state, and educational institution purchases where regulatory adherence is mandatory. The cable originates from the United States, which satisfies TAA country-of-origin requirements.
What is the maximum distance this cable can support?
This active optical cable supports reliable data transmission up to 15 meters (49.2 feet). The active optical technology maintains signal integrity across this distance, making it suitable for most rack-to-rack and within-data-center connections without requiring signal boosters or additional conditioning equipment.
What devices is this cable compatible with?
The cable is designed as a compatible replacement for HP 721076-B21 modules and works with network devices supporting QSFP+ and SFP+ interfaces. It undergoes compatibility testing to ensure seamless integration with existing equipment without requiring special configuration, firmware updates, or driver installations.
What warranty comes with this cable?
AddOn provides a lifetime limited warranty for this cable, offering long-term protection against manufacturing defects and performance issues. This warranty coverage demonstrates confidence in the product's durability and reliability for continuous operation in demanding network environments.
What are the advantages of active optical cable technology?
Active optical cable technology integrates electrical-to-optical conversion at each connector end, providing superior signal integrity compared to passive copper cables, especially at medium distances. AOC cables are lighter, more flexible, and generate less heat than equivalent copper solutions, while offering better electromagnetic interference immunity and longer reach capabilities within data center environments.
