Product Description
This Cisco breakout cable converts a single 40G QSFP+ port into four separate 10G SFP+ connections, making it an effective solution for splitting high-bandwidth links into multiple lower-speed segments. Often found in data centers and enterprise network closets, it simplifies aggregation and connectivity between switches and servers. Engineered for IT professionals and network engineers, it is built to enhance flexibility while maintaining signal quality over short distances. The active optical design ensures reduced interference and longer reach compared to copper alternatives. Key Features Four independent 10G lanes aggregated into a single 40G link Compact 1-meter length for neat cable management Active optical technology minimizes signal degradation Compatible with Cisco QSFP+ and SFP+ ports Supports hot-pluggable operation for easy deployment This cable is typically deployed within data center racks or network distribution areas where splitting a 40G port into multiple 10G ports is required. It helps optimize port utilization without sacrificing performance or reliability. Its optical design also reduces electromagnetic interference, making it suitable for dense networking environments where signal integrity is crucial.

Use Cases
The QSFP-4X10G-AOC1M cable is predominantly utilized in data center environments requiring high-density, multi-rate connectivity. It serves network architects and infrastructure engineers who need to efficiently break out 40G links into multiple 10G channels to optimize port usage while maintaining low latency and high throughput. How It's Used: Connecting top-of-rack switches to servers in virtualization environments where multiple 10G links are needed from a single 40G uplink. Facilitating high-speed interconnects in storage clusters requiring multiple 10G paths for data replication and backup operations. Deploying in enterprise IT infrastructures to aggregate 10G SFP+ connections from legacy network equipment into newer 40G QSFP+ capable devices. Supporting edge computing installations where compact, low-power cabling solutions simplify rack deployments with constrained space. Enabling high-performance computing (HPC) clusters to efficiently distribute 10G bandwidth from centralized 40G backbone links. This breakout cable enhances operational efficiency by allowing flexible network segmentation without additional hardware complexity. It supports scalable network architectures that require granular bandwidth allocation, ensuring optimal use of existing fiber infrastructure while maintaining data integrity and reducing power consumption.
