More About The Siemon Company
The Siemon Company focuses on physical network infrastructure for enterprise, government, industrial, and service provider environments, supplying structured cabling and connectivity that support Ethernet, IP, and related network protocols. Its portfolio is organized around copper and fiber structured cabling systems (network infrastructure), data center physical infrastructure (data center infrastructure), and intelligent building and converged IP cabling solutions (smart building infrastructure).
In enterprise LANs and campus networks, Siemon provides end-to-end structured cabling systems (network infrastructure) designed to support standardized categories of twisted-pair copper cabling and multimode and singlemode fiber optic cabling. These systems are designed to carry Ethernet traffic at various speeds, Power over Ethernet (PoE), and other IP-based services. Components typically include patch panels, outlets, modular jacks, patch cords, and trunk assemblies (network connectivity), which together form the physical layer in accordance with standards from bodies such as ISO/IEC and TIA for structured cabling.
For data center environments, The Siemon Company offers racks, cabinets, cable management systems, and high-density copper and fiber connectivity (data center infrastructure). These products are positioned for use in architectures such as spine-leaf, Top-of-Rack (TOR), end-of-row, and middle-of-row switching layouts, supporting high-speed Ethernet and storage networking over copper and fiber media. High-density patching systems, pre-terminated trunk cabling, and cable management accessories are used to organize cross-connects and interconnects between network, server, and storage equipment.
In the intelligent building domain, Siemon provides cabling and connectivity solutions (intelligent building infrastructure) designed to support converged IP systems such as PoE lighting, access control, video surveillance, wireless access points, and building automation. These solutions are intended to support higher power levels over structured cabling following PoE and related IEEE standards, and to facilitate zoned cabling designs for flexible space utilization in commercial buildings.
The company also publishes technical resources, design guidelines, and reference architectures (professional support and enablement) to help planners and integrators align cabling and connectivity deployments with applicable building, safety, and network standards. Within an enterprise IT and OT procurement taxonomy, The Siemon Company is categorized under structured cabling systems, copper and fiber connectivity, data center physical infrastructure, and intelligent building network infrastructure.
