The Siemon 40Gb/s AOC QSFP+ High Speed Interconnect Active Optical Cable delivers reliable, low-latency connectivity for modern data centre and enterprise environments. It is compatible with QSFP+ networking equipment, and provides a lightweight, high-bandwidth alternative to copper cabling while ensuring consistent interoperability, extended reach, and superior signal integrity.
It supports data transfer rates of up to 40Gb/s, making it ideal for connecting switches, servers, storage systems, and high-performance computing platforms across racks or longer intra-data-centre distances. It is suitable for enterprise networks, cloud computing infrastructures, virtualised environments, and hyperscale data centres where high bandwidth and reliable long-reach connectivity are essential for optimal performance.
It has integrated optical transceivers and factory-terminated fibre and features a hot-pluggable QSFP+ interface for quick, tool-free installation and replacement without disrupting active network operations. The active optical design provides extended reach, immunity to electromagnetic interference, and reduced signal degradation over distance.
Each cable is tested for compatibility, durability, and reliability across supported platforms, while its low power consumption and lightweight construction improve airflow and simplify cable management in high-density environments.
