Connectivity and compatibility

This cable fits any standard QSFP+ port, making it a versatile choice for connecting switches, routers, servers, and storage nodes in enterprise data centers. Its compatibility with Cisco systems ensures seamless integration in mixed-vendor environments. The optical design supports high-speed Ethernet, Infiniband QDR, and Fibre Channel networks, covering a broad range of high-performance computing and storage applications.

Performance and reliability

The active optical cable design provides a stable 40 Gbps connection with minimal signal degradation over its 15-meter length. The optical fiber core protects data transmission from electromagnetic and radio frequency interference, which can affect copper cables in crowded rack environments. Its low power draw and hot-swappable capability contribute to reliable, energy-efficient operation with minimal downtime during maintenance or upgrades.

Ideal uses and environments

This cable is well suited for enterprise data centers, virtualized environments, and high-performance computing clusters that require fast and reliable interconnects. It works effectively in setups where rack density and airflow are concerns, thanks to its thin and lightweight jacket. Organizations running 40 Gigabit Ethernet backbones, Infiniband QDR clusters, or Fibre Channel storage networks will find this cable a practical and efficient solution for their connectivity needs.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
