Frequently Asked Questions
What is a 100G QSFP28 breakout cable used for?
A 100G QSFP28 breakout cable splits a single 100G connection into four 25G lanes, enabling flexible port configurations in data centers. This allows organizations to connect multiple servers or switches using a single high-capacity port, optimizing network architecture and reducing infrastructure costs.
Why choose an Active Optical Cable over copper alternatives?
Active Optical Cables (AOCs) provide superior performance over extended distances without signal degradation. This 20-meter AOC eliminates EMI interference, supports longer cable runs than copper, and delivers consistent low-latency performance essential for mission-critical data center operations.
Is this cable compatible with my Mellanox switch?
Yes, this UNC Group cable is specifically engineered for Mellanox systems. The QSFP28 to SFP28 breakout configuration is fully compatible with Mellanox switches, adapters, and network infrastructure that support 100G and 25G optical connectivity standards.
What distance can this 20M fiber optic cable support?
The 20-meter length accommodates extended cable runs typical in large data center environments, providing flexibility in rack placement and network topology design while maintaining full optical signal integrity and performance specifications.
