Frequently Asked Questions
What is a 100G QSFP28 active optical cable used for?
A 100G QSFP28 AOC is used to connect high-speed networking equipment in data centers and enterprise environments. This cable supports 100Gbps connections between Mellanox switches, servers, and storage systems, providing the bandwidth needed for demanding applications like cloud computing, virtualization, and real-time analytics.
How does the 4x SFP28 breakout configuration work?
The 4x SFP28 breakout splits the single 100G QSFP28 connection into four separate 25Gbps SFP28 lanes. This allows you to connect multiple 25GbE devices to a single 100G port, providing flexibility in network architecture and enabling gradual infrastructure upgrades without replacing existing equipment.
Is this cable compatible with my Mellanox switch?
Yes, the UNC Group MFA7A50-C005-U is specifically designed for Mellanox 100GbE networks. It supports QSFP28 and SFP28 interfaces found on Mellanox switches, NICs, and network adapters. Verify your equipment's port specifications to ensure compatibility before installation.
What are the advantages of a 5-meter active optical cable?
A 5-meter AOC provides extended reach beyond standard copper cables while maintaining signal integrity and low latency. Active optical cables are ideal for rack-to-rack connections, cross-cabinet deployments, and environments where electromagnetic interference is a concern, all while supporting full 100Gbps performance.
