FAQ About 40G QSFP+ Active Optical Cable
A 40G QSFP+ Active Optical Cable (AOC) is a high-speed cable with optical fiber and integrated transceivers that support 40Gbps data transmission over short distances. It uses QSFP+ connectors and is ideal for data centers requiring low power, high-bandwidth connectivity.
40G AOC cables are commonly used for short-range, high-speed connections such as server-to-switch links, switch stacking, and high-performance computing (HPC) clusters. Their lightweight and flexible design makes them a popular choice in modern data center architectures.
Fibrecross 40G QSFP+ AOC cables support reach distances up to 100 meters over OM3 or OM4 multimode fiber, making them ideal for top-of-rack and intra-rack deployments in data centers.
Yes, Fibrecross 40G AOC cables are fully compatible with major vendors like Cisco, Dell, Juniper, Arista, and more. Each cable is tested to ensure 100% interoperability with branded equipment.
A 40G AOC cable offers a plug-and-play solution with lower power consumption, reduced latency, and better electromagnetic interference (EMI) resistance. It eliminates the need for separate transceivers and patch cables, reducing complexity and cost.
