4. Product Introduction
The Extreme Networks 40GB-F15-QSFP is a 40G QSFP+ Active Optical Cable that provides a direct 40 Gigabit Ethernet connection over 15 meters. It integrates four optical lanes for high-bandwidth, low-latency links between switches, routers, or servers.
Network engineers use this AOC for cost-effective, reliable interconnects inside data centers or between racks in automation backbone applications. It eliminates the need for separate transceivers and fiber patch cords while delivering plug-and-play 40G performance.

6. Frequently Asked Questions (FAQ)
What is the maximum supported distance for the 40GB-F15-QSFP? This 15-meter Active Optical Cable is designed for short-reach applications up to its rated length. Performance is best within that range.
Is this a passive cable or active? It is an Active Optical Cable with integrated electronics for signal regeneration, allowing reliable 40G performance over the full length.
Will it work in any QSFP+ port? It is compatible with Extreme Networks equipment supporting 40G QSFP+. Always verify port specifications and firmware support on your specific switch model.
Can I use this for 4x10G breakout? This is a standard 40G AOC. For breakout to 4x10G, use dedicated breakout cables or transceivers.
How do I clean and handle the connectors? Use fiber optic cleaning tools on the MPO-style interfaces. Avoid touching the optical surfaces and always use protective caps when not connected.
What condition are your units? New Original / New Surplus. Cables undergo continuity testing, insertion loss verification, and functional link testing with compatible Extreme hardware. Test reports available.
Is this a direct replacement for shorter 40G cables? Yes, it provides a longer-reach option. Ensure total cable length does not exceed switch port specifications and maintain proper installation practices.
