Foss

What Foss does

Foss (legal name Foss Fiber Optics AS) is a Norwegian manufacturer of fiber optic infrastructure that designs, produces, and sells connectivity systems for demanding industrial and mission-critical environments. Operating since 1984 from a Drammen, Norway headquarters and a Bratislava, Slovakia manufacturing subsidiary (Foss Fibre Optics s.r.o.), the company serves telecommunications, transportation, defense, offshore/maritime, industrial, and data center segments. Its customer base is concentrated in the Nordic and Central European markets (Norway as primary, plus Slovakia and Czech Republic) and includes blue-chip anchors such as the Norwegian Armed Forces (Forsvaret), Equinor, Kongsberg, Statnett, Hydro, Aker Solutions, Bane Nor, Telenor, Telia, and CERN.

The product portfolio is organized into four core lines: Fiber Optic Systems (cables, connectors, patch panels, wall boxes, MPO connectivity), Rugged Fiber (ProBeam, D38999, Hawke, HARTING Han and other ruggedized connectors engineered for shock, vibration, and temperature extremes), Foss Data Center Systems (pre-terminated high-density solutions with cooling-integrated cubes and transceivers up to 800Gbps), and Plug & Play pre-terminated assemblies. Supporting products span splice closures, xWDM/CWDM components, network electronics, transceivers, fiber sensing (distributed acoustic sensing over a dual-channel 100km range), and Seikoh Giken-based polishing equipment. The company's technical differentiation rests on in-house manufacturing across Norway and Slovakia (3,500+ sqm), which enables strict quality control, bespoke customization, and short delivery times, supplemented by representation of world-leading brands (CommScope, Prysmian, Leoni, Tykoflex).

Foss operates a hardware-sales business model driven by a sales-led B2B go-to-market motion: direct account management with technical consultation for enterprise and government projects, complemented by a multi-language (English, Slovak, German) e-commerce storefront for standard catalog products. Revenue is generated through fiber optic hardware sales, project-based pre-terminated Plug & Play deployments, bespoke custom engineering for defense and industrial clients, and, from autumn 2024, a new structured cabling line for the Norwegian market. Pricing is not publicly disclosed and operates on quote-based terms (quotes valid 30 days, 14-15 day payment terms). The company is wholly owned by DiscoverIE Plc, a London Stock Exchange-listed FTSE250 manufacturer and distributor of electrical components, and holds ISO 9001 (TUV NORD) and ISO 14001 certifications.
