What Siemon does

Siemon (legal entity: The Siemon Company) is a privately held, family-owned designer and manufacturer of IT infrastructure solutions headquartered in Watertown, Connecticut, founded in 1903 and led by President & CEO Henry Siemon with John Siemon as COO. The company produces copper cabling systems (Category 5E through 7A), singlemode and multimode fiber optic systems, and a growing portfolio of high-speed connectivity products including Direct Attach Copper (DAC), Active Copper/AEC assemblies, Active Optical Cables (AOC), and 200G–800G PAM4 optical transceivers supporting both Ethernet and InfiniBand. Proprietary platforms include PowerGUARD+ (extended-reach PoE cabling up to 200m, 75°C thermal tolerance), LightVerse fiber systems with third-party verified ultra-low-loss performance to 800G, Z-PLUG field-terminated plugs, MapIT G2 automated infrastructure management, and TERA-MAX/Z-MAX/UltraMAX copper connectivity. Siemon supplements its OEM Technologies division and Global Project Services (GPS) professional services arm with quick-ship programs (RapidDAC, FiberNOW) delivering assemblies in five days or less.

Revenue is generated through three primary streams: (1) hardware sales of connectivity solutions via a multi-tier channel model that combines direct enterprise field sales, a global Certified Installer (CI) and Registered Installer (RI) program accessed through the Siemon Connect partner portal, and a distributor network in more than 100 countries; (2) professional services including global project management, infrastructure moves adds & changes (I-MAC), break-fix Layer 1 support, cabling audits, and design services; and (3) technology licensing, most prominently the 2025 AEC patent licensing pact with Credo Technology Group Holding Ltd. The company targets four customer segments: enterprise and hyperscale/AI-focused data centers (its primary segment), smart buildings (Wi-Fi, PoE lighting, AV, IoT sensors), cellular networks (small cell/macro cell and modular data centers), and OEM partners requiring custom connectivity solutions. Pricing is quote-based through certified installers and distributors rather than direct-to-consumer. Manufacturing spans seven production/warehousing sites globally, including a 2026-opened Tijuana, Mexico line dedicated to PAM4 cable assemblies.
