Cisco Compatible Active Optical Cable (AOC) Connects Network Equipment at Speeds up to 40 Gbps
Black Box QSFP+ Active Optical Cables provide premium, error-free performance for data, storage, and high-performance computing (HPC) interconnectivity. 100% compatible with Cisco QSFP-H40G-AOC10M= and other lengths, you can rest assured when making connections among your Cisco switches, routers, and servers. Constructed for full compliance with the QSFP+ Multi-Source Agreement (MSA) and SFF-8436 industry standards, you can also make connections amongst your non-Cisco, non-proprietary 40Gb networking equipment. Programmed, tested, and serialized to ensure compliance and functionality, Black Box Active Optical Cables are the ideal solution for 40Gb Ethernet, Infiniband QDR, 4G/8G/10G Fiber Channel applications, and more.

Design, Performance, and Savings
The ultra-thin and light construction is ideal for high-density racks, placing less strain on ports and improving airflow to help cool equipment. AOCs utilize optical technology for higher bandwidth and reliable, ultra-fast data transmission over longer distances, far exceeding the 5-meter limitation where copper DAC solutions begin to fail with excessive bit error rates.

Integration and Low Latency
These cables offer a convenient, all-in-one, hot-swappable design, eliminating the need for separate transceivers and cables. Integrating the optics minimizes connection points, resulting in significantly lower latency - crucial for maintaining data integrity.

Interference Resistance and Security
The fiber optic construction provides a minimal EMI/RFI profile, ensuring superior resistance to signal interference. This is paramount for maintaining data integrity in sensitive, ultra-high-density applications. Fiber optic transmission is inherently resistant to tapping, adding a layer of physical security to your data.
