Frequently Asked Questions
What is a 100G QSFP28 active optical cable used for?
A 100G QSFP28 AOC is used to connect high-speed network switches to multiple servers or network devices in data centers. The active optical design enables 100 Gbps data transfer over fiber optic cables, making it ideal for demanding applications like cloud infrastructure, HPC clusters, and enterprise storage networks.
How does this QSFP28 4X SFP28 cable differ from copper direct attach cables?
Unlike copper DACs, this fiber optic AOC eliminates electromagnetic interference, supports longer distances without signal degradation, and generates less heat. The active optics provide superior performance in dense data center environments where multiple high-speed connections are required simultaneously.
Is the UNC GROUP MFA7A50-C007-U compatible with non-Mellanox equipment?
This cable is optimized for Mellanox-based infrastructure. While it may work with other 100G-capable QSFP28 and SFP28 ports, full compatibility and performance are guaranteed only with Mellanox switches and network adapters. Verify endpoint specifications before deployment.
What is the maximum recommended distance for this 7-meter AOC?
The 7-meter reach is ideal for in-rack and adjacent-rack deployments in standard data center topologies. This distance minimizes latency while maintaining signal integrity for 100GBase transmission without requiring additional amplification or regeneration.
